See Traction Control System (TCS) on page 4-10, StabiliTrak® System on page 4-6 or Enhanced StabiliTrak® on page 4-6. When road conditions allow you to safely use it again, the Adaptive Cruise Control can be turned back on. 3-23 Increasing Set Speed While Using Adaptive Cruise Control There are two ways to increase the set speed: (cid:129) Use the accelerator to get to the higher speed. Press T at the end of the lever, then release the button and the accelerator pedal. The vehicle will now cruise at the higher speed. (cid:129) Move the Adaptive Cruise Control switch from R to S . Hold it there until the desired set speed is displayed in the HUD, then release the switch. To increase the set speed in small amounts, move the switch brieﬂy to resume/increase. Each time this is done, the vehicle set speed increases by about 1 mph (1.6 km/h). Your vehicle will not reach the set speed until the system determines there is no vehicle in front of you. At that point, your vehicle speed will increase to the set speed. Decreasing Set Speed While Using Adaptive Cruise Control Press T at the end of the lever until the lower speed desired is reached, then release the button. To slow down in small amounts, brieﬂy press T . Each this is done, the set speed will be 1 mph (1.6 km/h) slower. Resuming a Set Speed If the brakes are applied while the Adaptive Cruise Control is at a set speed, this disengages the Adaptive Cruise Control. But it does not need to be reset. Once the vehicle reaches about 30 mph (48 km/h) or more, move the Adaptive Cruise Control switch brieﬂy from R to S . Adaptive Cruise Control will be engaged with the speed previously selected. 3-24 Selecting the Follow Distance (GAP) When the system detects a slower moving vehicle, it will adjust your vehicle’s speed and maintain the following distance (gap) selected. Use the GAP button on the steering wheel to adjust the follow distance between your vehicle and other vehicle’s. There are six follow distances to choose from. The follow distance selection ranges from near to far (one second to two seconds follow time). The distance maintained for a selected follow distance varies based on vehicle speed. The faster the vehicle speed the further back you will follow. Consider traffic and weather conditions when selecting the follow distance. The range of selectable distances may not be appropriate for all drivers and driving conditions. If you prefer to travel at a following distance farther than Adaptive Cruise Control allows, disengage the system and drive manually. A graphic on the HUD indicates the selected following distance. This picture shows a maximum follow distance. Press the top of the button to increase the distance or the bottom of the button to decrease the distance. The ﬁrst button press shows the current follow distance setting on the HUD. The current following distance setting is maintained until it is changed. United States version shown, Canada similar The vehicles will move closer together as you select a smaller following distance. 3-25 Alerting the Driver The alert symbol ﬂashes on the HUD and a warning beep sounds when driver action is required. Driver action is required when: (cid:129) Adaptive Cruise Control cannot apply sufficient braking because you are approaching a vehicle too rapidly. The vehicle speed drops below about 25 mph (40 km/h). (cid:129) A temporary condition prohibits Adaptive Cruise Control from operating. See DIC Warnings and Messages on page 3-79 for more information. (cid:129) A malfunction is detected in the system. See DIC Warnings and Messages on page 3-79 for more information. See Defensive Driving on page 4-2. { CAUTION: Adaptive Cruise Control has only limited braking ability to slow your vehicle. In some cases, Adaptive Cruise Control may not have time to slow your vehicle enough to avoid a collision. Be ready to take action and apply the brakes yourself. See Defensive Driving on page 4-2. Approaching and Following a Vehicle The vehicle ahead symbol only appears on the HUD when a vehicle ahead is detected in your path. If this symbol does not appear, or disappears brieﬂy, Adaptive Cruise Control will not respond to vehicles you may see ahead. 3-26 (cid:129) { CAUTION: When the Adaptive Cruise Control radar is blocked by snow, ice, or dirt, it may not detect a vehicle ahead. Adaptive Cruise Control may not have time to slow your vehicle enough to avoid a collision. Do not use Adaptive Cruise Control when the radar is blocked by snow, ice, or dirt. Keep your radar clean. See “Cleaning the System” later in this section. Adaptive Cruise Control automatically slows your vehicle down when approaching a slower moving vehicle. It then adjusts your speed to follow the vehicle in front at the selected following distance. Your speed increases or decreases to follow the vehicle in front of you but will not exceed the set speed. It may apply limited braking, if necessary. When braking is active, your brake lights come on. It may feel or sound different than if you were applying the brakes yourself. This is normal. Stationary or Very Slow-Moving Objects { CAUTION: Adaptive Cruise Control may not detect and react to stationary or slow-moving vehicles or other objects ahead of you. You could crash into an object ahead of you. Do not use Adaptive Cruise Control when approaching stationary or slow-moving vehicles or other objects. { CAUTION: Adaptive Cruise Control may not detect and react to stationary or slow-moving vehicles or other objects ahead of you. Your vehicle may accelerate toward objects, such as a stopped vehicle that suddenly appears after the lead vehicle changes lanes. Your complete attention is always required while driving and you should be ready to take action and apply the brakes. 3-27 Low-Speed Deactivation If your speed falls below 25 mph (40 km/h) while following a vehicle ahead, Adaptive Cruise Control will begin to disengage. The driver alert symbol on the HUD will ﬂash and the warning beep will sound. The driver must take action since Adaptive Cruise Control will not slow the vehicle to a stop. Deactivation When Head-Up Display is Turned Off If the HUD is turned off when Adaptive Cruise Control is engaged, it will begin to disengage. A warning beep sounds and the message RADAR CRUISE NOT READY appears on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-79 for additional information. If Adaptive Cruise Control was braking when the HUD is turned off, the braking will continue brieﬂy. Passing a Vehicle/Adaptive Cruise Control Override To increase speed to pass a vehicle, use the accelerator pedal. While you are doing this, the system will not automatically apply the brakes. A PEDAL APPLIED ACC OVERRIDE message will appear on the HUD. See Head-Up Display (HUD) on page 3-43 for additional information. Once you pass the vehicle and remove your foot from the accelerator pedal, Adaptive Cruise Control returns to normal operation and the brakes can be applied, if needed. { CAUTION: If you rest your foot on the accelerator pedal, the system will not automatically apply the brakes. You could crash into a vehicle ahead of you. Do not rest your foot on the accelerator pedal when using Adaptive Cruise Control. 3-28 Curves in the Road { CAUTION: Due to Adaptive Cruise Control limitations in curves, it may respond to a vehicle in another lane, or may not have time to react to a vehicle in your lane. You could crash into a vehicle ahead of you, or lose control of your vehicle. Give extra attention in curves and be ready to use the brakes if necessary. Select an appropriate speed while driving in curves. Adaptive Cruise Control might operate differently in a sharp curve. It might reduce your speed if the curve is too sharp. When following a vehicle and entering a curve, Adaptive Cruise Control could lose track of the vehicle in your lane and your vehicle could accelerate. When this happens, the vehicle ahead symbol will not appear on the HUD. 3-29 Highway Exit Ramps { CAUTION: Adaptive Cruise Control may lose track of the vehicle ahead and accelerate up to your set speed while entering or on highway exit ramps. You could be startled by this acceleration and even lose control of the vehicle. Disengage Adaptive Cruise Control before entering a highway exit ramp. Do not use Adaptive Cruise Control while entering or on exit ramps. Other Vehicle Lane Changes Adaptive Cruise Control might detect a vehicle that is not in your lane and apply the brakes. Adaptive Cruise Control might occasionally provide a driver alert and/or braking that you consider unnecessary. It could respond to signs, guardrails, and other stationary objects when entering or exiting a curve. This is normal operation. Your vehicle does not need service. 3-30 If another vehicle enters the same lane as you, Adaptive Cruise Control will not detect the vehicle until it is completely in the lane. Be ready to take action and apply the brakes yourself. Using Adaptive Cruise Controls on Hills and When Towing a Trailer How well Adaptive Cruise Control works on hills and while a trailer is being towed depends on your vehicle speed, vehicle load, traffic conditions, and the steepness of the hills. It might not detect a vehicle in your lane while driving on hills. While going up steep hills, you might want to use the accelerator pedal to maintain your vehicle speed. While going downhill and towing a trailer, you might want to brake to keep your vehicle speed down. Applying the brake disengages the system. You may choose not to use Adaptive Cruise Control on steep hills when towing a trailer. Disengaging Adaptive Cruise Control Apply the brake pedal or move the Adaptive Cruise Control switch to off, to disengage the system. Adaptive Cruise Control information does not appear on the HUD while the system is not engaged. Erasing Set Speed Memory The set speed memory is erased when the Adaptive Cruise Control switch or the ignition is turned off. Other Messages There are three messages that may appear on the DIC. They are SERVICE RADAR CRUISE, RADAR CRUISE NOT READY and CLEAN RADAR. These messages will appear to indicate a problem with the Adaptive Cruise Control. See DIC Warnings and Messages on page 3-79 for more information. Cleaning the System The radar can become blocked by snow, ice, or dirt. If this happens, turn off the engine and clean the emblem/ lens, located in the center of the front outside grille. Do not use Adaptive Cruise Control in icy conditions, or when visibility is low, such as in fog, rain or snow. To clean the emblem/lens, wipe the surface with a soft cloth. After cleaning the emblem/lens, engage the Adaptive Cruise Control. If you are unable to do so, see your dealer/retailer. 3-31 Headlamps The exterior lamp control is located in the middle of the turn signal/multifunction lever. O (Exterior Lamp Control): Turn the control with this symbol on it to operate the exterior lamps. The exterior lamp control has four positions: O (Off): Turns off all lamps and automatic lighting features, including Daytime Running Lamps (DRL) and IntelliBeam™. This is a momentary switch that springs back to the AUTO position when released. An AUTOMATIC LIGHTS ON message appears on the DIC when automatic lights are enabled or an AUTOMATIC LIGHTS OFF message appears on the DIC when the automatic lights are disabled. 3-32 AUTO (Automatic): Turns the exterior lamps on and off automatically depending upon how much light is outside of the vehicle. The automatic lights may be disabled even if the control is in the AUTO position. To enable automatic lighting do any of the following: Turn the headlamp control from AUTO to off and release the switch. It returns back to the AUTO position by itself. Turn the headlamp control from the parking lamp position to AUTO. Turn the headlamp control from the headlamp position to AUTO. To disable automatic lighting do any of the following: Turn the headlamp control from AUTO to off and release the switch. It returns back to the AUTO position by itself. Turn the headlamp control from AUTO to the parking lamp position. Turn the headlamp control from AUTO to the headlamp position. Disabling automatic lighting disables the automatic headlamp operation, DRL, and IntelliBeam™ High-Beams (if the vehicle has them). (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) ; (Parking Lamps): Turns on the parking lamps together with the following: (cid:129) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights 5 (Headlamps): Turns on the headlamps, together with the previously listed lamps and lights. IntelliBeam™ Intelligent High-Beam Headlamp Control System For vehicles with IntelliBeam, read this entire section before using this feature. IntelliBeam is an enhancement to the vehicle’s headlamp system. It uses a light sensor located on the back of the rearview mirror to turn the high-beam headlamps on and off depending on approaching traffic. The IntelliBeam system turns the high-beam headlamps on when it is dark enough, there is no other traffic present, and the IntelliBeam system is enabled. Turning On and Enabling IntelliBeam AUTO 3 (IntelliBeam On/Off): Press and release the IntelliBeam button on the inside rear view mirror. The indicator on the mirror turns on. Once the system has been turned on, it remains on each time the vehicle is started. Additionally, the IntelliBeam system must be enabled. To enable the System, turn the exterior lamp control to AUTO, with the turn signal/multifunction lever in its starting position. The High-Beam On Light appears on the instrument panel cluster when the high-beams are on. See Highbeam On Light on page 3-70. The vehicle has variable intensity high-beams. The high-beam indicator on the instrument panel cluster comes on as soon as the high-beams start to come on, and remains on until the high-beams have completely turned off. Vehicles with IntelliBeam quickly turn off the high-beams if the system detects the sudden presence of vehicle lights ahead. 3-33 (cid:129) (cid:129) (cid:129) Driving with IntelliBeam IntelliBeam only activates the high-beams when driving over 20 mph (32 km/h). The high-beam headlamps remain on, under the control of IntelliBeam, until any of the following situations occur: The system detects an approaching vehicle’s headlamps. The system detects a preceding vehicle’s taillamps. The outside light is bright enough that high-beam headlamps are not required. The high-beam headlamps are manually turned on or you use the ﬂash-to-pass feature. See Headlamp High/Low-Beam Changer on page 3-9 and Flash-to-Pass on page 3-13. When either of these conditions occur, the IntelliBeam feature is temporarily disabled until the high-beam stalk is returned to its starting position. If either of these conditions occur and IntelliBeam already has the high-beam headlamps on, the feature is disabled and the light in the mirror turns off. The exterior lamp control is turned to any setting except AUTO. When this occurs, IntelliBeam is disabled until the control is turned back to the AUTO position and the AUTOMATIC LIGHTS ON message displays on the DIC. 3-34 The IntelliBeam system is turned off at the inside rearview mirror. The vehicle’s speed drops below 15 mph (24 km/h). IntelliBeam may not turn off the high-beams if the system cannot detect other vehicle’s lamps because of any of the following: The others vehicle’s lamp(s) are missing, damaged, obstructed from view, or otherwise undetected. The other vehicle’s lamp(s) are covered with dirt, snow and/or road spray. The other vehicle’s lamp(s) cannot be detected due to dense exhaust, smoke, fog, snow, road spray, mist, or other airborne obstructions. (cid:129) Your vehicle’s windshield is dirty, cracked, or obstructed by something that blocks the view of the IntelliBeam light sensor. (cid:129) Your vehicle’s windshield is covered with ice, dirt, haze, or other obstructions. (cid:129) Your vehicle is loaded such that the front end of the vehicle points upward, causing the IntelliBeam sensor to aim high and not detect headlamps and taillamps. (cid:129) You are driving on winding or hilly roads. You might need to manually disable or cancel the high-beam headlamps by turning the low-beam headlamps on, if any of the above conditions exist. (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) Disabling and Resetting IntelliBeam at the Rearview Mirror IntelliBeam can be disabled and reset to the original factory setting by using the controls on the inside rearview mirror. AUTO 3 (IntelliBeam On/Off): To disable the system, press this button on the inside rearview mirror. The IntelliBeam indicator turns off and does not come back on until the IntelliBeam button is pressed again. When IntelliBeam has turned on the high-beams, pull or push the high-beam stalk. This disables IntelliBeam and the IntelliBeam indicator on the rearview mirror turns off. To re-enable IntelliBeam, press the IntelliBeam button on the mirror. A different sensitivity setting is available for dealer diagnostics. This is done by pushing and holding this button for 20 seconds until the light ﬂashes three times. If you accidentally activate this, the vehicle’s setting automatically resets each time the ignition is turned off and then on again; otherwise, refer to the text above for resetting the system. Cleaning the IntelliBeam Light Sensor The light sensor is located on the inside of the vehicle at the back of the rearview mirror. Clean the light sensor window, periodically, using glass cleaner on a soft cloth. Gently wipe the sensor window. Do not spray glass cleaner directly on the surface of the sensor window. 3-35 Wiper Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers have been in use for about six seconds. For this feature to work, automatic lighting must be enabled. See Headlamps on page 3-32 for additional information. When the ignition is turned off, the wiper-activated headlamps will immediately turn off. They will also turn off if the windshield wiper control is turned off. Headlamps on Reminder A warning chime will sound if the exterior lamp control is left on in either the headlamp or parking lamp position and the driver’s door is opened with the ignition off. See Lights On Reminder on page 3-70 for additional information. Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. The DRL system comes on when the following conditions are met: It is still daylight and the ignition is on. The automatic lights are enabled. The transmission is not in P (Park). When DRL are on, only the front turn signal lamps will be on. No other exterior lamps will be on when the DRL are being used. The instrument panel will not be lit. When the automatic lights are enabled and it is dark enough outside, the DRL will turn off and the low-beam headlamps will turn on. When it is bright enough outside, the low-beam headlamps will go off, and the DRL will turn back on. If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it will take about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness lever is in the full bright position. See Instrument Panel Brightness on page 3-40. 3-36 (cid:129) (cid:129) (cid:129) Light Sensor To operate the vehicle with the DRL off, turn the exterior lamp control off and then do one of the following: Turn the exterior lamp control to the parking lamp position. Turn the exterior lamp control to the headlamp position. Turn the exterior lamp control from AUTO to off and back to AUTO. An AUTOMATIC LIGHTS OFF message will appear on the DIC, showing that automatic lighting has been disabled. See DIC Warnings and Messages on page 3-79. The regular headlamp system should be turned on when needed. The light sensor for the DRL is located on top of the instrument panel. If the sensor is covered, it will prevent it from sensing light, and the exterior lamps may come on when they are not needed. 3-37 (cid:129) (cid:129) (cid:129) Twilight Sentinel® Twilight Sentinel® can turn the lamps on and off for you. A light sensor on top of the instrument panel makes the Twilight Sentinel work, so be sure it is not covered. Fog Lamps The fog lamp controls are located on the turn signal/multifunction lever. # (Fog Lamps): The band with this symbol is used to turn the fog lamps on and off. The parking lamps must be on for the fog lamps to work. To turn the fog lamps on or off, turn the fog lamp band on the lever up to the dot and release it. The band will return to its original position. If the high-beam headlamps are turned on, the fog lamps will turn off. The fog lamps will come back on when the high-beam headlamps are off. Some localities have laws that require the headlamps to be on along with the fog lamps. 3-38 With Twilight Sentinel the following will happen: (cid:129) When it is dark enough outside, the front turn signal lamps (DRL) will go off, and the headlamps and parking lamps will come on. The other lamps that come on with headlamps will also come on. (cid:129) When it is bright enough outside, the headlamps will go off, and the front turn signal lamps (DRL) will come on, as long as the exterior lamp switch is in the off position. If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it will take about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster might not be as bright as usual. Make sure the instrument panel brightness control is in full bright position. See Instrument Panel Brightness on page 3-40 for more information. You can idle the vehicle with the lamps off, even when it is dark outside. First set the parking brake while the ignition is in OFF/ACCESSORY. Then start the vehicle. The lamps will stay off until the parking brake is released. Twilight Sentinel also provides exterior illumination as you leave the vehicle. If Twilight Sentinel has turned on the lamps when you turn off the ignition, the lamps will remain on until: The exterior lamp switch is moved from off to the parking lamp position. (cid:129) A delay time that you select has elapsed. See Vehicle Personalization on page 2-61 to select the delay time needed. You can also select no delay time. If the ignition is turned off with the exterior lamp switch in the parking lamp or headlamp position, the Twilight Sentinel delay will not occur. The lamps will turn off as soon as the switch is turned off. As with any vehicle, the regular headlamp system should be turned on when needed. 3-39 (cid:129) Exterior Lighting Battery Saver If the parking lamps or headlamps have been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned off. This protects against draining the battery in case you have accidentally left the headlamps or parking lamps on. The battery saver does not work if the headlamps are turned on after the ignition is turned off. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on. Instrument Panel Brightness Press the center knob on the DIC control panel to extend. Then turn the knob clockwise to brighten the lights or counterclockwise to dim them. If the knob is turned completely clockwise, the interior lamps turn on. Base Level Shown, Uplevel Similar 3-40 Entry Lighting The entry lighting system turns on the reading and dome lamps and the backlighting to the exterior lamp control when a door is opened or if you press the remote keyless entry transmitter unlock button. If activated by the transmitter, the lighting will remain active for about 25 seconds. The entry lighting system uses the light sensor; it must be dark outside in order for the lamps to turn on. The lamps turn off about 25 seconds after the last door is closed. They will dim to off if the ignition is on, or immediately deactivate if the power locks are activated. Parade Dimming This feature prohibits dimming of the instrument panel displays and backlighting during daylight hours when the key is in the ignition and the headlamps are on. This feature operates with the light sensor and is fully automatic. When the light sensor reads darkness outside and the parking lamps are active, the instrument panel displays can be adjusted by turning the instrument panel brightness knob. See Instrument Panel Brightness on page 3-40 for additional information. Reading Lamps The reading lamps are located on the overhead console. These lamps come on automatically when any door is opened. For manual operation, press the button next to each lamp to turn it on or off. If the reading lamps are left on, they automatically shut off 10 minutes after the ignition has been turned off. Battery Load Management The battery load management feature is designed to monitor the vehicle’s electrical load and determine when the battery is in a heavy discharge condition. During times of high electrical loading, the engine may idle at a higher revolutions per minute (rpm) setting than normal to make sure the battery charges. High electrical loads may occur when several of the following are on: headlamps, high beams, fog lamps, rear window defogger, the climate control fan at high speeds, heated seats and engine cooling fans. If the battery continues to discharge, even with the engine idling at a higher rpm setting, some electrical loads will automatically be reduced. When this occurs, the rear window defogger may take slightly longer to clear the glass and the fan may cut back to a lower speed. For more battery saving information, see “Battery Saver Active Message” under DIC Warnings and Messages on page 3-79. 3-41 Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery’s state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as Battery Saver Active or Service Battery Charging System. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 3-79. Inadvertent Power Battery Saver This feature is designed to protect the vehicle’s battery against drainage from the interior lamps, trunk lamp, glove box lamp, or the garage door opener. When the ignition is turned off, the power to these features will automatically turn off after 10 minutes (three minutes if a new car has 15 miles (24 km) or less). Power will be restored for an additional 10 minutes if any door is opened, the trunk is opened or the courtesy lamp switch is turned on. 3-42 Head-Up Display (HUD) { CAUTION: If the HUD image is too bright, or too high in your ﬁeld of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the HUD image dim and placed low in your ﬁeld of view. For vehicles with the Head-Up Display (HUD), some of the driver information that appears on the instrument panel cluster is projected onto an image on the windshield. The information can be displayed in English or metric units. To change from English to metric units, see DIC Operation and Displays on page 3-72. The HUD consists of the following information: (cid:129) Speedometer Turn Signal Indicators (cid:129) High-Beam Indicator Symbol (cid:129) Driver Shift Control Transmission Feature, see Automatic Transmission Operation on page 2-30 (cid:129) Check Gages Icon (cid:129) Adaptive Cruise Control Features and Indicators (If Equipped), see Adaptive Cruise Control on page 3-20 Forward Collision Alert Features and Indicators (If Equipped), see Forward Collision Alert (FCA) System on page 3-9 (cid:129) Radio Features United States version shown, Canada similar Always scan the instrument panel displays, controls and driving environment just as you would in a vehicle without HUD, so important warning lights are not missed. Under important warning conditions, the CHECK GAGES message will display in the HUD. View the Driver Information Center (DIC) for more information. 3-43 (cid:129) (cid:129) Brightness Control: Press the knob on the center of the DIC control panel to extend and then pull the knob until is completely extended. Turn the knob clockwise or counterclockwise to increase or decrease the brightness of the HUD display. To adjust the HUD so it can be seen properly: 1. Adjust the seat to a comfortable driving position, before adjusting the HUD position. 2. Start the engine. 3. Adjust the position and brightness of the HUD display. The brightness of the HUD display is determined by the light conditions in the direction the vehicle is facing and where the HUD has been positioned on the windshield. If the vehicle is facing a dark object or a heavily shaded area, the HUD may begin to dim because it anticipates the vehicle entering a dark area. When sunlight enters the HUD it can make it difficult to see the display. The display will return to normal brightness when the sunlight no longer enters the HUD. Wearing polarized sunglasses could also make the HUD display harder to see. The HUD controls are located to the left of the steering wheel on the DIC control panel. Off: Turn the brightness control knob fully counterclockwise to turn the HUD display off. ~ (Head-Up Display): Press to move the HUD display up or down on the windshield. HUD cannot be adjusted side-to-side. 3-44 The Ignition is On and the HUD Image Cannot Be Seen Check to see if: The HUD unit is covered. The brightness is adjusted properly. The HUD display is adjusted to the proper height. (cid:129) Ambient light in the direction the vehicle is facing is low. (cid:129) A fuse is blown. See Fuses and Circuit Breakers on page 5-123. The windshield is part of the HUD system. See Windshield Replacement on page 5-52. The following messages may appear in the HUD: SPEED ALERT When the Speed Advisor feature is turned on, HUD displays either the posted or advisory speed as determined by the information on the map disc in the navigation system. To turn the Speed Advisor on or off, see DIC Operation and Displays on page 3-72. The Speed Advisor can be set to show a speed alert when the vehicle speed exceeds the speed alert limit as set in the DIC menu. Depending on the level of the HUD on the vehicle, your HUD may work like either of the following: The HUD speedometer will turn red when the vehicle speed exceeds the speed alert limit. When the vehicle speed is at or below the alert limit and above the posted speed or advisory speed, the speedometer turns yellow. If the Speed Alert setting in the DIC is set to AT LIMIT, the speedometer will not turn yellow. When the vehicle speed is at or below the posted speed or advisory speed, the speedometer remains green. The HUD speedometer will turn yellow when the vehicle speed exceeds the speed alert limit. When the vehicle speed is at or below the alert limit, the speedometer remains green. Posted Speed Advisory Speed 3-45 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) PEDAL APPLIED ACC OVERRIDE When the PEDAL APPLIED ACC OVERRIDE message displays, the accelerator pedal is being pressed and the Adaptive Cruise Control is overridden and cannot automatically apply the brakes. Once the accelerator pedal is released, the Adaptive Cruise Control will return to normal operation and be able to apply the brakes, if needed. An Adaptive Cruise Control active symbol, alert symbol or vehicle ahead symbol may also appear. See Adaptive Cruise Control on page 3-20 for more information. Care of the HUD Clean the inside of the windshield as needed to remove any dirt or ﬁlm that reduces the sharpness or clarity of the HUD display. To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry. Notice: When cleaning, be careful not to scratch the HUD or camera lenses. Do not spray glass cleaner directly on the HUD lens because the cleaner could leak inside the unit and cause damage. Accessory Power Outlet(s) Accessory power outlets can be used to plug in electrical equipment, such as a cellular telephone. The vehicle has one outlet in front of the center console, one in the center console lid and there may be an additional outlet in the rear of the center console. The vehicle may have a small cap that must be removed to access the accessory power outlet. Be sure to cover the outlet with the protective cap when it is not in use. Notice: Leaving electrical equipment plugged in for an extended period of time while the vehicle is off will drain the battery. Power is always supplied to the outlets. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum 20 ampere rating. Certain accessory power plugs may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer for additional information on the accessory power outlets. Notice: Adding any electrical equipment to the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not 3-46 use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. Follow the proper installation instructions that are included with any electrical equipment you install. Notice: damage not covered by the warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Improper use of the power outlet can cause If papers, pins, or other ﬂammable items Ashtray(s) and Cigarette Lighter The vehicle may have an ashtray and cigarette lighter.

Ashtray For vehicles with an ashtray, it is located under the climate control panel on the center console. Press on the door to release the ashtray. The ashtray automatically slides open for use. To empty the ashtray with the ashtray in full open position, locate the release button to the right of the ash receiver and slide it to the right (in the direction of the arrow). The ash receiver will unlock and lift slightly and can then be easily removed from the housing. To replace the ash receiver, place it into position in the ashtray housing and push down ﬁrmly until it locks into place. Cigarette Lighter Notice: Holding a cigarette lighter in while it is heating will not allow the lighter to back away from the heating element when it is hot. Damage from overheating may occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. Do not use equipment exceeding maximum amperage rating of 15 amperes. The cigarette lighter is located next to the ashtray. The vehicle does not have any cigarette lighters for the rear seat passengers. To activate the cigarette lighter, push it into the heating element and let go. When the lighter is ready it will pop back out by itself. 3-47 Climate Controls Dual Climate Control System The heating, cooling, and ventilation can be controlled for the vehicle with this system. Automatic Operation Vehicles With Heated and Ventilated Seats Shown, Vehicles Without Similar A. Driver and Passenger Side Power Buttons B. Ventilated Seat C. AUTO D. Recirculation E. Air Conditioning F. Heated Seat G. Fan Control H. Defrost I. Rear Window Defogger J. Air Delivery Mode Control 3-48 AUTO (Automatic): The system automatically controls the fan speed, air delivery, air conditioning and recirculation modes in order to heat or cool the vehicle to the desired temperature. To place the system in automatic mode: 1. Press the AUTO button. 2. Adjust the temperature to a comfortable setting, generally, between 70°F (21°C) and 80°F (27°C). Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. If the system is set at the warmest temperature setting, the system will try to continuously heat the vehicle and will not adjust the system down as the vehicle warms up. To avoid blowing cold air in cold weather, the system delays turning on the fan until warm air is available. The system starts out blowing air at the ﬂoor, but can automatically change modes as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up depends on the outside temperature and the length of time that has elapsed since the vehicle was last driven. 3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then adjust the temperature, if necessary. The display can be changed from English to metric units through the Driver Information Center (DIC). See DIC Operation and Displays on page 3-72. Manual Operation O (Driver’s Temperature Control): Press to turn the entire climate control system on or off. Turn the knob to increase or decrease the temperature inside the vehicle. O (Passenger’s Temperature Control): Press to turn the passenger climate control system on. Turn the knob to increase or decrease the temperature for the front passenger only. The passenger side power button does not turn off the climate control system. The system is set to the same setting as the driver. y A z (Fan Control): Press to increase or decrease the fan speed. This cancels automatic operation and lets the amount of airﬂow be adjusted manually. Press AUTO to return to automatic operation. If the airﬂow seems low when the fan speed is at the highest setting, the passenger compartment air ﬁlter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-54 and Scheduled Maintenance on page 6-4. y N z (Air Delivery Mode): Press to change the direction of the airﬂow in the vehicle. This cancels automatic operation and lets the air delivery mode be adjusted manually. Press AUTO to return to automatic operation. The outboard air outlets always receive airﬂow regardless of the mode selected. See Outlet Adjustment on page 3-52 to change this airﬂow from the outboard outlets. To change the current mode, select one of the following: Y (Vent): Air is directed to the instrument panel outlets. \ (Bi-Level): Air is divided between the instrument panel outlets and the ﬂoor outlets. In automatic operation, cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. [ (Floor): Air is directed to the ﬂoor outlets, with some air directed to the windshield and side windows. 3-49 - (Defog): This mode clears the windows of fog or moisture. Air is directed to the windshield and ﬂoor outlets, with some air directed to the side windows and outboard panel outlets. When this mode is selected, the system turns off recirculation and runs the air-conditioning compressor unless the outside temperature is at or below freezing. If recirculation is selected while in the defog mode, it is cancelled after 10 minutes. If there is fogging on the side windows, remain in defog or defrost mode until they clear. 0 (Defrost): This mode clears the windshield of fog or frost more quickly. Air is directed to the windshield, with some air directed to the side windows and outboard panel outlets. The air-conditioning compressor runs automatically in this setting, unless the outside temperature is at or below freezing. Recirculation cannot be selected while in the defrost mode. This mode can also cause the fan speed and air temperature to increase. ^ (Air Conditioning): Press to turn the air conditioning off. Press AUTO to return to automatic operation. To limit fogging on the windshield, the air conditioning compressor cannot be off while in the defrost mode. h (Recirculation): Press once to select recirculation mode or twice to select outside air. If in AUTO mode, press h once to select recirculation. This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to prevent outside air and odors from entering the vehicle. Recirculation is not available in the defrost mode and shuts off when defog mode is selected. Both of these features are designed to limit fogging in the vehicle. If recirculation is selected during defog mode, it automatically turns off after 10 minutes. Using the recirculation for long periods of time might cause the air inside the vehicle to become too dry or stuffy. To prevent this from happening, after the air in the vehicle has cooled, press the recirculation button again to select outside air or press the AUTO button. 3-50 Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The defogger only works when the ignition is on or during remote start, if programmed. See “Personal Settings Menu” under Vehicle Personalization on page 2-61 for additional information. = (Rear Window Defogger): Press to turn the rear window defogger on or off. The rear window defogger stays on for 10 minutes, before turning off. If the vehicle’s speed is above 30 mph (48 km/h), the rear defogger stays on continuously. If turned on again, the defogger only runs for about ﬁve minutes before turning off. The defogger can also be turned off by turning off the engine. The heated outside rearview mirrors also heat to help clear fog or frost from the surface of the mirror when the rear window defogger is on. See Outside Heated Mirrors on page 2-41. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger.

The interior temperature sensor located on the instrument panel to the right of the steering wheel, measures the temperature of the air inside the vehicle. The climate control system uses the information from these sensors to adjust the temperature, the fan speed and the air delivery, in order to maintain the selected temperature. The system may also supply cooler air to the side of the vehicle facing the sun. Do not cover the sensors or the automatic climate control system will not work properly. 3-52 Outlet Adjustment Use the lever located in the center of each outlet to change the direction of the airﬂow, either side-to-side or up and down. Use the thumbwheels to open or close the outlets to adjust the airﬂow. Turn the thumbwheel towards the vehicle door to open the outlets and allow the maximum amount of air to enter your vehicle. Turn the thumbwheel towards the center console to close the outlets and minimize the amount of air entering the vehicle. Operation Tips (cid:129) Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the ﬂow of air into your vehicle. (cid:129) Use of non-GM approved hood deﬂectors may adversely affect the performance of the system. (cid:129) Keep the path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. If the airﬂow seems low when the fan speed is at the highest setting, the passenger compartment air ﬁlter may need to be replaced. For more information, see Passenger Compartment Air Filter on page 3-54. (cid:129) Rear Climate Control System The vehicle has a rear climate control system. The base model includes air outlets in the rear of the center console for cooling and under-seat air outlets for heating. The temperature, amount of airﬂow, and the air delivery mode is controlled automatically by the front climate control system. Some vehicles may have an optional climate control panel for the rear passenger, located on the back of the center console. A. Temperature Control B. Air Delivery Mode C. Heated Seat D. Heated Seat Control Indicator 9 (Off): Turns off the airﬂow to the rear seat passengers. With the air delivery off there may be an increase in the air rush sound of the front system. Temperature Control: Turn clockwise or counterclockwise to increase or decrease the temperature. Air Delivery Mode Control: Turn to change the direction of the airﬂow for the rear seat passengers. To change the current mode, select one of the following: Y (Vent): Air is directed to the console outlets. \ (Bi-Level): Air is directed to the console and the ﬂoor outlets. [ (Floor): Air is directed to the ﬂoor outlets. The front climate control system automatically controls the amount of airﬂow to the rear seat passengers, regardless of optional equipment. Airﬂow to the rear system turns off when defrost is selected on the front climate control panel, in order to direct air to clear the windshield. z (Heated Seat): Press to turn on rear heated seats. There are two buttons, each with three indicator lights, located between the climate control knobs on the rear climate control panel. Keep the area under the front seats clear of any objects so the air in the vehicle can circulate effectively. 3-53 Passenger Compartment Air Filter Your vehicle may be equipped with a passenger compartment air ﬁlter. There are two types of ﬁlters available. There is a standard dust ﬁlter that traps small particles including pollen. There is, also, a dust/odor ﬁlter available that traps dust and pollen and uses a charcoal element to help reduce many offensive odors from entering your vehicle. The ﬁlter will need to be changed periodically. For information on when to change the passenger compartment air ﬁlter, see Scheduled Maintenance on page 6-4. Notice: Driving without a passenger compartment air ﬁlter in place can cause water and small particles, like paper and leaves, to be pulled into your climate control system which may cause damage to it. Make sure you always replace the old ﬁlter with a new one. 3-54 The access panel for the passenger compartment air ﬁlter is located under the hood near the windshield, on the passenger side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. See Doing Your Own Service Work on page 5-4 for information on doing your own service work. To access the passenger compartment air ﬁlter: 1. Pull back the rubber hood seal from the edge of the leaf screen vent cover. 2. Remove the three fasteners that hold the ﬁlter cover in place and slide the cover off. 3. To access the ﬁlter, remove the water deﬂector by lifting the outboard edge of the deﬂector to release the retention tab. 4. Lift the inboard edge of the deﬂector to release the retention tab. 5. Lift and slide the water deﬂector toward the inboard side and remove it. 6. The top edge of the ﬁlter should be visible. Reach in and lift the ﬁlter out, pulling upward and toward the front of the vehicle. 7. Insert the new air ﬁlter by sliding it back into place. Make sure the arrow on the ﬁlter is pointing toward the passenger compartment. Reverse steps 1 through 3 to reinstall the water deﬂector, ﬁlter cover and the hood seal. Warning Lights, Gages, and Indicators Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gages could prevent injury. Warning lights come on when there may be or is a problem with one of the vehicle’s functions. Some warning lights come on brieﬂy when the engine is started to indicate they are working. Gages can indicate when there may be or is a problem with one of the vehicle’s functions. Often gages and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gages shows there may be a problem, check the section that explains what to do. Follow this manual’s advice. Waiting to do repairs can be costly and even dangerous. 3-55 Instrument Panel Cluster The instrument panel cluster is designed to show how the vehicle is running. It shows how fast the vehicle is going, how much fuel is being used and many of the other things needed to drive safely and economically. United States Base version shown, Canada and Uplevel similar 3-56 Speedometer and Odometer The speedometer shows the speed in both miles per hour (mph) and kilometers per hour (km/h). See “MPH (km)” under DIC Operation and Displays on page 3-72 for more information. The odometer mileage can be checked without the vehicle running. The vehicle’s odometer works together with the driver information center. The odometer can be set for a Trip A and a Trip B. See “Trip Information” under DIC Operation and Displays on page 3-72 for more information. If the vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer. Tachometer This gage indicates the engine speed in revolutions per minute (rpm). Safety Belt Reminders Driver Safety Belt Reminder Light When the engine is started, a chime sounds for several seconds to remind the driver to fasten the safety belt, unless the driver’s safety belt is already buckled. The driver safety belt light comes on and stays on for several seconds, then ﬂashes for several more. This chime and light are repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s safety belt is already buckled, neither the chime nor the light comes on. 3-57 Passenger Safety Belt Reminder Light Several seconds after the engine is started, a chime sounds for several seconds to remind the front passenger to buckle their safety belt. This only occurs if the passenger airbag is enabled. See Passenger Sensing System on page 1-59 for more information. The passenger safety belt light, located on the instrument panel, comes on and stays on for several seconds and then ﬂashes for several more. Airbag Readiness Light The system checks the airbag’s electrical system for possible malfunctions. If the light stays on it indicates there is an electrical problem. The system check includes the airbag sensor, the pretensioners, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 1-51. This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. The airbag readiness light ﬂashes for a few seconds when the engine is started. If the light does not come on then, have it ﬁxed immediately. If the passenger safety belt is buckled, neither the chime nor the light comes on. 3-58 { CAUTION: If the airbag readiness light stays on after the vehicle is started or comes on while driving, it means the airbag system might not be working properly. The airbags in the vehicle might not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury, have the vehicle serviced right away. If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message can also come on. See DIC Warnings and Messages on page 3-79 for more information. Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your overhead console has a passenger airbag status indicator. United States Canada When you start the vehicle, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. If you use remote start to start your vehicle from a distance, if your vehicle has this feature, you may not see the system check. 3-59 Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol to let you know the status of the right front passenger’s frontal airbag. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inﬂate). { CAUTION: If the on indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Do not use a rear-facing child restraint in the right front passenger’s seat if the airbag is turned on. { CAUTION: Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off. If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. See Passenger Sensing System on page 1-59 for more on this, including important safety information. If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer/retailer for service. 3-60 { CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the airbag(s). See Airbag Readiness Light on page 3-58 for more on this, including important safety information. Charging System Light This light comes on brieﬂy when the ignition key is turned to START, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear. See DIC Warnings and Messages on page 3-79 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner. 3-61 Brake System Warning Light The vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking both parts need to be working. If the warning light comes on, there is a brake problem. Have the brake system inspected right away. United States Canada This light comes on brieﬂy when the engine is turned on. If it does not come on then, have it ﬁxed so it will be ready to warn if there is a problem. When the ignition is on, the brake system warning light also comes on when the parking brake is set. The light will stay on if the parking brake does not release fully. If it stays on after the parking brake is fully released, it means there is a brake problem. If the light comes on while driving, pull off the road and stop carefully. The pedal may be harder to push, or the pedal may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-29. { CAUTION: The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service. 3-62 Antilock Brake System (ABS) Warning Light Traction Control System (TCS) Warning Light For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started. The TCS warning light comes on brieﬂy when the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the ABS light stays on, turn the ignition off. If the light comes on while driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light stays on, or comes on again while driving, the vehicle needs service. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-62. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-79 for all brake related DIC messages. If it does not, have the vehicle serviced by your dealer/retailer. If the Traction Control System (TCS) warning light comes on and stays on, there may be a problem with the TCS. The light also comes on if the TCS is turned off using the traction control on/off button located on the console. If this light stays on or comes on while driving, pull off the road as soon as possible and stop carefully. Turn the engine off and then restart it. If the light still stays on or comes back on again while driving, the vehicle needs service. Have the TCS inspected as soon as possible. See Traction Control System (TCS) on page 4-10 and StabiliTrak® System on page 4-6 for more information. Also see Competitive Driving Mode on page 4-11 for more information. 3-63 Lane Departure Warning Light For vehicles with the lane departure warning system, this light brieﬂy comes on green, while starting the vehicle, to indicate that it is working. Engine Coolant Temperature Warning Light The engine coolant temperature warning light comes on when the engine is very hot. If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light will then go off. This light also comes on green if the system detects a left or right lane marking. It ﬂashes, changes to amber and three beeps sound if a detected lane marking is crossed without using a turn signal. For more information, see the Index in the Navigation Manual. This light also comes on brieﬂy when the vehicle is started. If the light does not go out or comes on and stays on while driving, there may be a problem with the cooling system. Driving with engine coolant temperature light on could cause the vehicle to overheat, see Overheated Engine Protection Operating Mode on page 5-36. See Engine Overheating on page 5-34 and DIC Warnings and Messages on page 3-79 for more information. 3-64 Engine Coolant Temperature Gage Tire Pressure Light This gage shows the engine coolant temperature. It can be used to see when the engine has warmed up and to make sure the cooling system is operating properly. If the gage pointer moves into the shaded area, the engine coolant is too hot and the engine coolant temperature warning light comes on. See Engine Overheating on page 5-34 for more information. For vehicles with a tire pressure light, this light comes on brieﬂy when the engine is started and provides information about tire pressures and the Tire Pressure Monitoring System. When the Light is On Steady This indicates that one or more of the tires is signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See DIC Warnings and Messages on page 3-79 for more information. Stop and check the tires as soon as it is safe to do so. If a tire is underinﬂated, inﬂate to the proper pressure. See Tires on page 5-54 for more information. 3-65 When the Light Flashes First and Then is On Steady This indicates that there could be a problem with the Tire Pressure Monitor System. The light ﬂashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor System on page 5-66 for more information. Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It makes sure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. This comes on brieﬂy while starting the engine. If it does not come on, have the vehicle serviced by your dealer/retailer. If the vehicle is continually driven with this If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction. Notice: light on, after a while, the emission controls might not work as well, the vehicle’s fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle’s emission controls and can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 5-3. 3-66 This light comes on during a malfunction in one of two ways: Light Flashing: A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on the vehicle. Diagnosis and service might be required. The following can prevent more serious damage to the vehicle: (cid:129) Reduce vehicle speed. (cid:129) Avoid hard accelerations. (cid:129) Avoid steep uphill grades. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the key off, wait at least 10 seconds, and restart the engine. If the light is still ﬂashing, follow the previous steps and see your dealer/retailer for service as soon as possible. Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. An emission system malfunction might be corrected by doing the following: (cid:129) Make sure the fuel cap is fully installed. See Filling the Tank on page 5-8. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. If the vehicle has been driven through a deep puddle of water, the vehicle’s electrical system might be wet. The condition is usually corrected when the electrical system dries out. A few driving trips should turn the light off. (cid:129) Make sure to fuel the vehicle with quality fuel. Poor fuel quality causes the engine not to run as efficiently as designed and may cause: stalling after start-up, stalling when the vehicle is changed into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up. If one or more of these conditions occurs, change the fuel brand used. It will require at least one full tank of the proper fuel to turn the light off. See Gasoline Octane on page 5-5. 3-67 (cid:129) If none of the above have made the light turn off, your dealer/retailer can check the vehicle. The dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed. Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection: The vehicle will not pass this inspection if the check engine light is on with the engine running. To perform a check engine light bulb check with the keyless ignition, make sure the transmitter fob is in the passenger compartment. See Ignition Positions on page 2-26. Press the bottom of the Acc. button on the instrument panel and hold the button down for ﬁve seconds. The instrument panel, including the check engine light, will light up and the ignition will be on, but the engine will not start — press the bottom of the Acc. button only brieﬂy, less than ﬁve seconds, the accessory power mode will be turned on, but not the ignition. After the bulb check, press and release the Acc. button again to turn the ignition off and avoid draining the vehicle’s battery. The vehicle will not pass this inspection if the OBD II (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if the battery has recently been replaced or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer/retailer can prepare the vehicle for inspection. 3-68 (cid:129) (cid:129) Oil Pressure Light For vehicles with an oil pressure light, if there is a problem with the oil, the light may stay on after the engine is started, or comes on while driving. This light indicates that oil is not going through the engine quickly enough to keep it lubricated. The engine could be low on oil or could have some other oil problem. Have it ﬁxed right away. The oil light could also come on in the following situations: The light comes on brieﬂy when the ignition is turned on to show that it is working properly. If it does not come on with the ignition on, there may be a problem with the fuse or bulb. Have it ﬁxed right away. (cid:129) Sometimes when the engine is idling at a stop, a chime sounds and the light may blink on and off. This is normal. { CAUTION: Do not keep driving if the oil pressure is low. The engine can become so hot that it catches ﬁre. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced. Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil. Security Light For information regarding this light and the vehicle’s security system, see Theft-Deterrent System on page 2-21. 3-69 (cid:129) Fog Lamp Light Cruise Control Light The fog lamp light comes on when the fog lamps are in use. This light comes on whenever the cruise control is set. The light goes out when the fog lamps are turned off. See Fog Lamps on page 3-38 for more information. Lights On Reminder The light goes out when the cruise control is turned off. See Cruise Control on page 3-16 and Adaptive Cruise Control on page 3-20 for more information. Highbeam On Light This light comes on whenever the parking lamps are on. This light comes on when the high-beam headlamps are in use. See Headlamps on Reminder on page 3-36 for more information. See Headlamp High/Low-Beam Changer on page 3-9 for more information. 3-70 Fuel Gage The fuel gage shows approximately how much fuel is in the fuel tank. It works only when the engine is on. An arrow on the fuel gage indicates the side of the vehicle the fuel door is on. If the fuel supply gets low, the “FUEL LEVEL LOW” message appears on the Driver Information Center (DIC) and a single chime sounds. See DIC Warnings and Messages on page 3-79 for more information. All of the following situations are normal and do not indicate that anything is wrong with the fuel gage: (cid:129) At the gas station the gas pump shuts off before the gage reads full. The gage may change when you turn, stop quickly or accelerate quickly. It takes a little more or less fuel to ﬁll the tank than the gage indicated. For example, the gage may have indicated that the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. 3-71 (cid:129) (cid:129) When the sport mode is active, an S will appear next to the shift position indicator on the center of the DIC display. When the manual mode is active, an M will appear on the DIC display. When the normal mode is active, only the shift position indicator will appear. While the Driver Shift Control (DSC) feature is active, the DIC will change to show the selected gear. See “Driver Shift Control (DSC)” under Automatic Transmission Operation on page 2-30 for more information. If a problem is detected, a warning message will appear on the display.

DIC Operation and Displays The Driver Information Center (DIC) has different modes which can be accessed by pressing the four DIC buttons located on the instrument panel, to the left of the steering wheel. Driver Information Center (DIC) The Driver Information Center (DIC) gives you the status of many of your vehicle’s systems. The DIC is also used to display warning/status messages. All messages will appear in the DIC display located at the bottom of the instrument panel cluster, below the tachometer and speedometer. The DIC buttons are located on the instrument panel, to the left of the steering wheel. The DIC comes on when the ignition is on. After a short delay, the DIC will display the current driver and the information that was last displayed before the engine was turned off. The top line of the DIC display shows the vehicle system information and the warning/status messages. The bottom line of the DIC display shows either the odometer, the trip odometer A or the trip odometer B information on the left side. Only one odometer can appear at a time. See “Trip Information” under DIC Operation and Displays on page 3-72 for information on changing the display to show the odometer or trip odometer information. The bottom line of the DIC display also shows the outside temperature on the right side and the shift lever position indicator in the center. See Automatic Transmission Operation on page 2-30 for more information on the shift lever positions. 3-72 DIC Buttons (Base Level) If your vehicle does not have a Head-Up Display (HUD), these are the buttons for the DIC. « 4 ª (Information): Press the top or bottom of this button to scroll through the available vehicle information displays which include digital speed display, if your vehicle has this feature, fuel range, fuel economy, fuel used, average speed, timer, battery voltage, tire pressure, and engine oil life, if your vehicle has this feature.

Information Display Menu Items The following display menu items can be displayed by pressing the information button. MPH (km/h) If the vehicle has this display, it shows the vehicle’s speed digitally in either miles per hour (mph) or kilometers per hour (km/h). MILES RANGE (km RANGE) This display shows the approximate number of remaining miles (mi) or kilometers (km) you can drive without reﬁlling the fuel tank. This estimate is based on the current driving conditions and will change if the driving conditions change. For example, if you are driving in traffic making frequent stops, the display may read one number, but if you enter the freeway, the number may change even though you still have the same amount of fuel in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. Once the range drops below about 40 miles (64 km) remaining, the display will show LOW RANGE. If your vehicle is low on fuel, the Fuel Level Low message will be displayed. See “Fuel Level Low” under DIC Warnings and Messages on page 3-79 for more information. MPG AVG (L/100 km AVG) This display shows the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number is calculated based on the number of mpg (L/100 km) recorded since the last time this display was reset. To reset MPG AVG, press the reset button. The display will return to zero. MPG INST (L/100 km INST) This display shows the current fuel economy. This number reﬂects only the fuel economy that the vehicle has right now and will change frequently as driving conditions change. Unlike average fuel economy, this display cannot be reset. GAL FUEL USED (L FUEL USED) This display shows the number of gallons (gal) or liters (L) of fuel used since the last reset of this display. To reset GAL FUEL USED, press the reset button. The display will return to zero. AVG MPH (AVG km/h) This display shows the average speed of the vehicle in miles per hour (mph) or kilometers per hour (km/h). This average is calculated based on the various vehicle speeds recorded since the last reset of this display. To reset AVG MPH, press the reset button. The display will return to zero. HUD Speed Advisor ON/OFF (On Vehicles with HUD) If the vehicle has HUD, you can choose to have the Speed Limit/Speed Advisory display appear in the HUD. The DIC will toggle between ON and OFF. Press the reset button to make your selection. See Head-Up Display (HUD) on page 3-43 for more information. 3-75 SPEED LIMIT: XXX MPH (SPEED LIMIT: XXX Km/h) or ADVISORY: XXX MPH (ADVISORY: XXX Km/h) (On Vehicles without HUD) This display will show the speed limit or the advised speed as determined by the information on the map disc in the navigation system. If there is no map disc in the navigation system, this display will not be available. The speed limit and speed advisory displays on the DIC and the HUD, if equipped, are for reference only. There may be segments of road where speed data has not been captured or times where incorrect speed data, or no speed data, will be displayed by the DIC and the HUD due to the navigation system not correctly matching the vehicle’s position to the actual road. Be aware of this and obey posted speed limits wherever you drive. SPEED ALERT This display will allow you to customize the speed alert warning. You can choose to have no warning display, or to have it display at the limit, at 5 mph (km/h) over the limit, or at 10 mph (km/h) over the limit. The DIC will toggle between OFF, AT LIMIT, +5, +10 (MPH or Km/h). Press the reset button to make your selection. TIMER OFF This display can be used like a stopwatch. You can record the time it takes to travel from one point to another. To access the timer, press the information button until 00:00:00 TIMER OFF displays. To turn on the timer, press the reset button until TIMER ON displays. The timer will then start. To turn off the timer, press the reset button again until TIMER OFF displays. The timer will stop and display the end timing value. To reset the timer, press and hold the reset button after the timer has been stopped. The display will return to zero. BATTERY VOLTS This display shows the current battery voltage. If the voltage is in the normal range, the value will display. For example, the display may read 13.2 BATTERY VOLTS. If the voltage is low, the display will have LOW after it. If the voltage is high, the display will have HIGH after it. Your vehicle’s charging system regulates voltage based on the state of the battery. The battery voltage may ﬂuctuate when viewing this information on the DIC. This is normal. See Charging System Light on page 3-61 for more information. If there is a problem with the battery charging system, the DIC may display a message. See DIC Warnings and Messages on page 3-79 and Electric Power Management on page 3-42 for more information. 3-76 Tire Pressure This display shows the pressure for each tire in either pounds per square inch (psi) or kilopascals (kPa). If the tire pressure is normal, the value will display. If the tire pressure is low or high, LOW or HIGH will appear on the display with the value. See Inﬂation - Tire Pressure on page 5-64 and DIC Warnings and Messages on page 3-79 for more information. Press the information button to scroll through the following displays: LF TIRE: This display shows the pressure in the driver side front tire. RF TIRE: This display shows the pressure in the passenger side front tire. LR TIRE: This display shows the pressure in the driver side rear tire. RR TIRE: This display shows the pressure in the passenger side rear tire. If the tire pressure display shows dashes instead of a value, there may be a problem with your vehicle. If this consistently occurs, see your dealer/retailer for service. ENGINE OIL LIFE If your vehicle has this display, it shows the estimated oil life remaining. If you see 99% ENGINE OIL LIFE on the display, that means that 99% of the current oil life remains. When the oil life is depleted, the CHANGE ENGINE OIL SOON message will appear on the display. Change the oil as soon as possible. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance on page 6-4 and Engine Oil on page 5-18. After an oil change, reset the ENGINE OIL LIFE display. To reset, see Engine Oil Life System on page 5-21. The display will show 100% ENGINE OIL LIFE after it has been reset. Also clear the CHANGE ENGINE OIL SOON message from the display. ENGLISH DISPLAY UNITS (METRIC DISPLAY UNITS) This display allows you to select between English and metric units of measurement if your vehicle has the uplevel DIC. Press the reset button to switch between English and metric units. Blank Line This display shows no information. 3-77 ENGINE BOOST (STS-V Only) This display shows a graphic that indicates the amount of boost the engine is receiving in either pounds per square inch (psi) or kilopascals (kPa). ENGINE OIL TEMPERATURE (STS-V Only) This display shows the engine oil temperature in either degrees Fahrenheit (°F) or degrees Celsius (°C). OIL PRESSURE (STS-V Only) This display shows the oil pressure in either pounds per square inch (psi) or kilopascals (kPa). TRANS (Transmission) FLUID TEMP (Temperature) (STS-V Only) This display shows the transmission ﬂuid temperature in either degrees Fahrenheit (°F) or degrees Celsius (°C). Trip Information Display Menu Items The following display menu items can be displayed by pressing the trip Information button. Odometer Press the trip information button until the odometer appears on the DIC display. The odometer shows the total distance the vehicle has been driven in either miles (mi) or kilometers (km).

The trip odometer shows the current distance traveled since the last reset for each trip odometer in either miles (mi) or kilometers (km). Both odometers can be used at the same time. For base level vehicles, each trip odometer can be reset to zero separately by pressing and holding the bottom of the trip information button while the desired trip odometer is displayed. For uplevel vehicles, reset each trip odometer by pressing the reset button or by pressing and holding the trip information button while the desired trip odometer is displayed. 3-78 DIC Warnings and Messages Messages are displayed on the DIC to notify the driver that the status of the vehicle has changed and that some action may be needed by the driver to correct the condition. Multiple messages may appear one after another. The text messages are the same for both the base audio and Navigation systems unless otherwise indicated. Some messages may not require immediate action, but you can press the reset button to acknowledge that you received the messages and to clear them from the display. Some messages cannot be cleared from the DIC display because they are more urgent. These messages require action before they can be cleared. Take any messages that appear on the display seriously and remember that clearing the messages will only make the messages disappear, not correct the problem. The following are the possible messages that can be displayed and some information about them. ADVISORY: XXX MPH (KM/H) This message displays when the Speed Alert has been turned on through the DIC Information Menu and the vehicle is at or above the advised speed. See DIC Operation and Displays on page 3-72 for more information. AUTOMATIC LIGHTS OFF This message displays when the automatic headlamps are turned off.
