on the inside of the vehicle in front of the inside 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. 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 3-31 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 3-71 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. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. The DRL system will make the turn signal lamps come on when the following conditions are met: It is still daylight and the ignition is on, the automatic lights are enabled, and the transmission is not in PARK (P). When DRL are on, only your front turn signal lamps will be on. No other exterior lamps will be on when the DRL are being used. Your instrument panel will not be lit. 3-35 (cid:127) (cid:127) (cid:127) Light Sensor The light sensor for the DRL is located on top of the instrument panel. If you cover the sensor, it will read dark, and the exterior lamps may come on when you do not need them. 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 you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave 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, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness lever is in the full bright position. See Instrument Panel Brightness on page 3-39. To operate your 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. As with any vehicle, you should turn on the regular headlamp system when you need it. 3-36 (cid:127) (cid:127) (cid:127) Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamp controls are located on the turn signal/multifunction lever. - (Fog Lamps): The band with this symbol is used to turn the front fog lamps on and off. The parking lamps must be on for the fog lamps to work. To turn the fog lamps on, turn the fog lamp band on the lever up to the dot and release it. The band will return to its original position. To turn the fog lamps off, turn the fog lamp band up to the dot and release it. The band will return to its original position, and the fog lamps will turn off. If you turn on the high-beam headlamps, the fog lamps will also turn off. They’ll turn back on again when you switch back to low-beam headlamps. Some localities have laws that require the headlamps to be on along with the fog lamps. Twilight Sentinel® Twilight Sentinel® can turn your 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. 3-37 With Twilight Sentinel® you will see the following happen: (cid:127) 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:127) 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 you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in full bright position. See Instrument Panel Brightness on page 3-39 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/ACC. Then start the vehicle. The lamps will stay off until you release the parking brake. 3-38 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, your lamps will remain on until: The exterior lamp switch is moved from off to the parking lamp position, or a delay time that you select has elapsed. See Vehicle Personalization on page 2-53 to select the delay time that you want. You can also select no delay time. If you turn off the ignition 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, you should turn on the regular headlamp system when you need it. 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. (cid:127) (cid:127) Instrument Panel Brightness This feature controls the brightness of the instrument panel lights. Base Level Shown, Uplevel Similar Press in the center knob on the DIC control panel until the knob pops out. Then turn the knob clockwise to brighten the lights or counterclockwise to dim them. If you turn the knob completely clockwise, the interior lamps will turn on. 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 3-39 for additional information. 3-39 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. Press it again to turn the lamp 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. 3-40 Inadvertent Power Battery Saver This feature is designed to protect your 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. 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. If equipped, the Head-Up Display (HUD) allows you to see some of the driver information that appears on your instrument panel cluster on the windshield. The information may be displayed in English or metric units and appears as an image focused out toward the front of your vehicle. To change from English to metric units, see DIC Controls and Displays on page 3-74. The HUD consists of the following information: (cid:127) Speedometer Turn Signal Indicators (cid:127) High-Beam Indicator Symbol (cid:127) Driver Shift Control Transmission Feature, see Automatic Transmission Operation (STS) on page 2-28 or Automatic Transmission Operation (STS-V) on page 2-32 (cid:127) Check Gages Icon (cid:127) Adaptive Cruise Control Features and Indicators (If Equipped), see Adaptive Cruise Control on page 3-19 Forward Collision Alert Features and Indicators (If Equipped), see Forward Collision Alert (FCA) System on page 3-9 (cid:127) Radio Features United States version shown, Canada similar Be sure to continue scanning your displays, controls and driving environment just as you would in a vehicle without HUD. If you never look at your instrument panel cluster, you may not see something important, such as a warning light. Under important warning conditions, the CHECK GAGES message will display in the HUD. View your Driver Information Center (DIC) for more information. 3-41 (cid:127) (cid:127) The HUD controls are located to the left of the steering wheel on the DIC control panel. ~ (Head-Up Display): Press this button to change the position of the HUD on the windshield. Press the top part of the button to move the HUD image up. Press the bottom part of the button to move the HUD image down. You can also adjust the brightness of the HUD image. Press the knob on the center of the DIC control panel in until it pops out and then pull the knob until is completely extended. Turn the knob clockwise or counter-clockwise to increase or decrease the brightness. If you turn the knob all the way to the left, the HUD image will turn off. 3-42 To adjust the HUD so you can see it properly, do the following: 1. Adjust the seat to a comfortable driving position. If you change your seat position later, you may have to re-adjust your HUD. 2. Start your engine and press the top or bottom of the HUD button to center the HUD image in your view. The HUD image can only be adjusted up and down, not side-to-side. 3. Turn the knob on the DIC control panel to adjust the brightness of the HUD image. The brightness of the HUD image is determined by the light conditions in the direction your vehicle is facing and where you have the HUD set. If you are facing a dark object or a heavily shaded area, your HUD may anticipate that you are entering a dark area and may begin to dim. To turn the HUD image off, turn the knob counter-clockwise. Polarized sunglasses could make the HUD image harder to see. As light shines out from the HUD, it is possible for light to shine back in. In rare occurrences, when the sun is at a speciﬁc angle and position, the sun’s rays can shine back into the HUD. When this occurs, the display device within the HUD will be temporarily illuminated. The event will end when the vehicle’s angle to the sun changes. Clean the inside of the windshield as needed to remove any dirt or ﬁlm that reduces the sharpness or clarity of the HUD image. To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry it. 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. If the ignition is on and you cannot see the HUD image, check to see if: (cid:127) Something is covering the HUD unit. The brightness is adjusted properly. The HUD image is adjusted to the proper height. (cid:127) Ambient light in the direction your vehicle is facing is low. (cid:127) A fuse is blown. See Fuses and Circuit Breakers on page 5-105. Keep in mind that your windshield is part of the HUD system. See Windshield Replacement on page 5-56. The following Adaptive Cruise Control message may appear in the HUD: PEDAL APPLIED ACC OVERRIDE: This message indicates that you are pressing your foot on the accelerator pedal and overriding Adaptive Cruise Control. While you are doing this, the system will not automatically apply the brakes. Once you remove your foot from the accelerator pedal, Adaptive Cruise Control will return to normal operation and be able to apply the brakes, if needed. You may also see an Adaptive Cruise Control active symbol, alert symbol or vehicle ahead symbol. See Adaptive Cruise Control on page 3-19 for more information. 3-43 (cid:127) (cid:127) CAUTION: (Continued) So, unless you check carefully behind you before and when you back up, you could strike children, pedestrians, bicyclists or pets behind you, and they could be injured or killed. Whether or not you are using rear park assist, always check carefully behind your vehicle before you back up and then watch closely as you do. The URPA display is located inside the vehicle, above the rear window. It has three color-coded lights that can be seen through the rearview mirror or by turning around. Ultrasonic Rear Parking Assist (URPA) The Ultrasonic Rear Parking Assist (URPA) system is designed to help you park while the vehicle is in REVERSE (R). It operates only at very low speeds, less than 3 mph (5 km/h). URPA can help make parking easier and help you avoid colliding with objects such as parked vehicles. The URPA system can detect objects up to 5 feet (1.5 m) behind the vehicle, and tell you how close these objects are from your rear bumper. {CAUTION: Even with the Ultrasonic Rear Park Assist system, the driver must check carefully before backing up. The system does not operate above typical backing speeds of 3 mph (5 km/h) while parking. And, the system does not detect objects that are more than 5 feet (1.5 meters) behind the vehicle. CAUTION: (Continued) 3-44 How the System Works URPA comes on automatically when the shift lever is moved into REVERSE (R) and the vehicle speed is less than 3 mph (5 km/h). When the system turns on, the three lights on the display will illuminate for one and a half seconds to let you know that the system is working. If your vehicle is moving in REVERSE (R) at a speed greater than 3 mph (5 km/h), the red light will ﬂash to remind you that the system does not work at a speed greater than 3 mph (5 km/h). If an object is detected at a REVERSE (R) speed of less than 3 mph (5 km/h), one of the following will occur: Description Amber light Amber/amber lights Amber/amber/red lights & continuous chime Amber/amber/red lights ﬂashing & continuous chime English 5 ft 40 in 20 in 1 ft Metric 1.5 m 1.0 m 0.5 m 0.3 m A chime will sound the ﬁrst time an object is detected between 20 inches (0.5 m) and 5 feet (1.5 m) away. URPA cannot detect objects that are above trunk level. In order for the rear sensors to recognize an object, it must be within detection range behind the vehicle. When the System Does Not Seem to Work Properly The light may ﬂash red when the vehicle is in REVERSE (R), if the ultrasonic sensors are not kept clean. So be sure to keep your rear bumper free of mud, dirt, snow, ice and slush. Other conditions that may affect system performance include things like the vibrations from a jackhammer or the compression of air brakes on a very large truck. If after cleaning the rear bumper and then driving forward at least 15 mph (25 km/h), the display continues to ﬂash red, see your dealer. If a trailer was attached to your vehicle, or a bicycle or an object was hanging out of your trunk during your last drive cycle, the light may also ﬂash red. The light will continue to ﬂash whenever in REVERSE (R) until your vehicle is driven forward at least 15 mph (25 km/h) without any obstructions behind the vehicle. For cleaning instructions, see Washing Your Vehicle on page 5-98. 3-45 Accessory Power Outlet(s) Your vehicle is equipped with accessory power outlets. The outlets can be used to plug in electrical equipment such as a cellular telephone, CB radio, etc. Your 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. Your vehicle may have a small cap that must be removed to access the accessory power outlet. If it does, when not using the outlet be sure to cover it with the protective cap. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always turn off electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage 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 your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating. Check with your dealer before adding electrical equipment. Follow the proper installation instructions that are included with any electrical equipment you install. Notice: damage not covered by your 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 3-46 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. 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. Ashtray(s) and Cigarette Lighter Your vehicle may have an ashtray and cigarette lighter. Notice: If you put papers, pins, or other ﬂammable items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your vehicle. Never put ﬂammable items in the ashtray. Ashtray The ashtray is located under the climate control panel on the center console. Press on the door to release the ashtray. The ashtray will automatically slide 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 reciever 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. There may also be ashtrays in the rear doors. 3-47 Climate Controls Dual Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. Automatic Operation Vehicles With Heated and Ventilated Seats Shown, Vehicles Without Similar AUTO (Automatic): When this button is pressed and the temperature is set, the system will automatically control the inside temperature, the air delivery mode, the air conditioning compressor, and the fan speed. 3-48 AUTO will appear on the display next to the fan, mode indicators, and recirculation indicator if your vehicle is equipped with the optional air quality sensor. 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 you set the system 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. In cold weather, the system may start at reduced fan speeds to avoid blowing cold air into your vehicle until warmer air is available. The system will start out blowing air at the ﬂoor but may change modes, automatically, as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up will depend on the outside temperature and the length of time that has elapsed since your 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. You can switch from English to metric units through the Driver Information Center (DIC). See DIC Controls and Displays on page 3-74. The air-conditioning system removes moisture from the air, so you may notice water dripping underneath your vehicle while idling or after turning off the engine. This is normal. Manual Operation yN z (Mode): Pressing the mode switch and changing the mode cancels automatic operation and allows the operator to manually select the air delivery location. Press AUTO to return to automatic operation. The outboard air outlets will always receive airﬂow regardless of the mode selected. See Outlet Adjustment on page 3-54 to change this airﬂow from the outboard outlets. To change the current mode, select one of the following: Y (Vent): This mode directs air to the instrument panel outlets. \ (Bi-Level): This mode directs approximately half of the air to the instrument panel outlets, and then directs most of the remaining air to the ﬂoor outlets. In automatic operation, cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. [ (Floor): This mode directs most of the air to the ﬂoor outlets with some air directed to the outboard outlets, and a little air directed to the windshield and side windows. The mode switch can also be used to select the defog mode. Information on defogging and defrosting can be found later in this section. yAz (Fan): Press this switch to increase or decrease the fan speed. Pressing this switch cancels automatic operation and allows the operator to manually select the amount of airﬂow. 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 3-55 and Scheduled Maintenance on page 6-4. h (Recirculation): This button controls the air source for the climate control system. If you are in AUTO mode, pressing this button once will choose recirculation. This mode keeps outside air from coming in the vehicle and recirculates the air in the vehicle. It can be used to prevent outside air and odors from entering your vehicle or to help cool the air inside your vehicle more quickly. 3-49 Recirculation is not available in the defrost mode and will shut off when defog mode is selected. Both of these features are designed to limit fogging in your vehicle. If recirculation is selected during defog mode, it will automatically turn off after 10 minutes to limit problems with fogging. In some conditions, using recirculation for long periods of time may cause the air inside your vehicle to become too dry or stuffy. To prevent this from happening, after the air in your vehicle has cooled, select AUTO to return to automatic climate control operation or push the recirculation button again to select outside air. Pressing this button a second time selects outside air. : (Outside Air): This mode forces the system to pull air from outside the vehicle. It can be used to bring fresh air into the vehicle. Air Quality Sensor: Your vehicle may be equipped with an optional air quality sensor to help limit the climate control system from pulling in some harmful exhaust fumes from older, poorly running or diesel-equipped vehicles that are driving near you. This sensor, when active, will monitor the air quality in front of your vehicle and switch to air recirculation when poor quality air is detected outside your vehicle. You can activate the air quality sensor on your vehicle (if equipped) by pressing the AUTO button on your climate control. The word AUTO will be shown in the center of the climate control display under the outline shape of a vehicle. When the air quality sensor senses poor quality air, the recirculation graphic will be shown as long as the sensor senses poor quality air. Under some conditions, the air quality sensor system will not operate. In cold weather, the system may not be active (even if the AUTO indication is displayed) because of concerns of fogging your windows, which may occur by activating recirculation mode. Also, the air quality sensor system will not remain in recirculation mode for extended periods of time that could cause stuffy or very dry conditions in the vehicle. Following a poorly running vehicle for an extended period of time may not keep recirculation active indeﬁnitely. 3-50 The air quality sensor will not activate due to organic odors, like skunk, and may not activate on many chemical-related odors. If you wish to limit these types of odors, you may choose to manually select recirculation. Your vehicle may also be equipped with a charcoal ﬁlter that can limit many odors from being pulled into your vehicle. This ﬁlter, like your engines air cleaner ﬁlter, will need to be changed periodically. See Scheduled Maintenance on page 6-4. The air quality sensor system does not protect against carbon monoxide (CO), which you cannot see or smell. See Engine Exhaust on page 2-39. O(Power Driver’s Temperature): Press the power button located on the driver’s side of the climate control panel to turn the entire climate control system on or off. Turn the knob to increase or decrease the temperature inside your vehicle. O(Power Passenger’s Temperature): Press the power button located on the passenger’s side of the climate control panel to turn the passenger’s climate control system on if they wish to have a different setting than the driver. Turn the knob to increase or decrease the temperature for the front passenger. Turning the passenger’s side power button off will not shut off the climate control system for the passenger. The system will be set to the same setting as the driver. { (Ventilated Seat): Press this button (if equipped) to turn on the ventilated seat for the driver’s or passenger’s side. See Heated and Ventilated Seats on page 1-4. J (Heated Seat): Press this button (if equipped) to turn on the heated seat and seatback for the driver’s or passenger’s side. See Heated and Ventilated Seats on page 1-4. ^ (Air Conditioning): Press this button to manually turn off the air conditioning compressor. Press AUTO to return to automatic operation or press the A/C OFF button again. To limit fogging on the windshield, the air conditioning compressor cannot be in off in defrost mode. 3-51 Sensors There is a solar sensor located on the instrument panel, near the windshield. There is also an interior temperature sensor located next to the steering wheel on the instrument panel. These sensors monitor the solar radiation and the air inside your vehicle, then use the information to maintain the selected temperature by initiating needed adjustments to the temperature, the fan speed and the air delivery system. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode may also be activated, as necessary. Do not cover the sensors or the automatic climate control system will not work properly. 3-52 Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog from your windshield. Use the defog mode to clear the windows of fog or moisture and warm the passengers. Use the defrost mode to remove fog or frost from the windshield more quickly. yN z (Mode): Press this button until defog appears on the display. - (Defog): This mode directs the air between the windshield and ﬂoor outlets with some air supplied to the outboard panel outlets and side window defogging outlets. When you select this mode, the system turns off recirculation and runs the air-conditioning compressor unless the outside temperature is at or below freezing. The recirculation mode is cancelled when you enter defog mode. If you select recirculation while in defog mode, it will be cancelled after 10 minutes. If you have fogging on the side windows, remain in defog or defrost mode until they clear. 0 (Defrost): Pressing the defrost button directs most of the air to the windshield, with some air directed to the side windows and outboard panel outlets. In this mode, the system will automatically turn off recirculation and run the air-conditioning compressor, unless the outside temperature is at or below freezing. Recirculation cannot be selected while in the defrost mode. This mode may also cause the fan speed and air temperature to increase. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger will only work when the ignition is in ON or during remote start, if programmed. See “Personal Settings Menu” under Vehicle Personalization on page 2-53 for additional information. = (Rear Window Defogger): Press this button to turn the rear window defogger on or off. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off about 10 minutes after the button is pressed, or if the vehicle’s speed is above 30 mph (48 km/h), the rear defogger will stay on continuously. If turned on again, the defogger will only run for about ﬁve minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. The heated outside rearview mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defogger button is on. 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. Repairs would not be covered by your warranty. 3-53 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 to the right to open the outlets completely and allow the maximum amount of air to enter your vehicle. Turn the thumbwheel to the left to close the outlets and minimize the amount of air entering the vehicle. Operation Tips (cid:127) 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:127) Use of non-GM approved hood deﬂectors may adversely affect the performance of the system. (cid:127) 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 3-55. 3-54 Rear Climate Control System Your 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, quantity, and air delivery location is controlled automatically by the front climate control system. Some vehicles are equipped with an optional climate control panel for the rear passenger, located on the back of the center console. The left knob controls the temperature of the air to the rear passengers. Turning the knob to the left will make the air cooler. Turning the knob to the right will make the air warmer. The right knob controls the air delivery to the rear passengers. Turning the knob all the way to the left will shut off airﬂow to the rear passengers. Operating with the rear air delivery off may make the entire vehicle warm or cool less quickly. It may also increase the air rush sound of the front system. (cid:127) 9(Off): This is the off position. Y (Vent): This mode directs all the rear passenger airﬂow to the outlets in the console. This is the normal position for cool down conditions. \ (Bi-Level): This mode directs airﬂow to the console outlets and the ﬂoor. [ (Floor): This mode directs all of the airﬂow to the ﬂoor. This is the normal position for warm up conditions. The amount of airﬂow to the rear passengers is controlled automatically by the front climate control system, regardless of optional equipment. Airﬂow to the rear system will be turned off when defrost is selected on the front climate control panel to direct air to clear the windshield. Vehicles equipped with a rear climate control panel, also, have heated rear seats. There are two buttons, each with three indicator lights, located between the two climate control knobs on the rear climate control panel, to control the rear heated seats. See Heated Seats on page 1-7 for additional information. Be sure to keep the area under the front seats clear of any objects so the air in your vehicle can circulate effectively. 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 also uses a charcoal element to help reduce many offensive odors from entering your vehicle. Like your vehicle’s engine air cleaner/ﬁlter, it will need to be changed periodically. For information on how often 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. 3-55 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. The access panel for the passenger compartment air ﬁlter is located under the hood near the windshield, on the passenger’s 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, do the following: 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 access cover in place and slide the cover off. 3. To access the ﬁlter, remove the black plastic water deﬂector by lifting the outboard edge of the deﬂector to release the retention tab. 3-56 Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. 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 your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle’s functions. As you will see in the details on the next few pages, some warning lights come on brieﬂy when you start the engine just to let you know they’re working. If you are familiar with this section, you should not be alarmed when this happens. Gages can indicate when there may be or is a problem with one of your vehicle’s functions. Often gages and warning lights work together to let you know when there’s a problem with your vehicle. When one of the warning lights comes on and stays on when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Follow this manual’s advice. Waiting to do repairs can be costly – and even dangerous. So please get to know your warning lights and gages. They’re a big help. Your vehicle also has a Driver Information Center (DIC) that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-73 for more information. 3-57 Instrument Panel Cluster The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, how much fuel you are using and many of the other things you will need to know to drive safely and economically. United States Uplevel version shown, Canada and base similar 3-58 Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). See “MPH (km)” under DIC Controls and Displays on page 3-74 for more information. The odometer mileage can be checked without the vehicle running. Your vehicle’s odometer works together with the driver information center. You can set a Trip A and a Trip B odometer. See “Trip Information” under DIC Controls and Displays on page 3-74 for more information. If your 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 Reminder Light When the ignition button is pressed to START, a chime will be provided for several seconds to remind people to buckle their safety belts. The driver safety belt light will also be provided and stay on for several seconds, then it will ﬂash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is buckled, neither the chime nor the light will be provided. 3-59 Passenger Safety Belt Reminder Light Several seconds after the ignition button is pressed to START, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 1-58 for more information. The passenger safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light will be repeated if the passenger remains unbuckled and the vehicle is in motion. Airbag Readiness Light There is an airbag readiness light on the instrument panel, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensors, the airbag modules, the wiring and the diagnostic module. For more information on the airbag system, see Airbag System on page 1-48. This light will come on when you start your vehicle, and it will ﬂash for a few seconds. Then the light should go out. This means the system is ready. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. If the airbag readiness light stays on after you start the vehicle or comes on when you are driving, your airbag system may not work properly. Have your vehicle serviced right away. 3-60 {CAUTION: If the airbag readiness light stays on after you start your vehicle, it means the airbag system may not be working properly. The airbags in your vehicle may not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the airbag readiness light stays on after you start your vehicle. The airbag readiness light should ﬂash for a few seconds when you turn the vehicle on. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If there is a problem with the airbag system in your vehicle, the Service airbag message will appear on the DIC display. See DIC Warnings and Messages on page 3-79 for more information. Passenger Airbag Status Indicator Your overhead console has a passenger airbag status indicator. Passenger Airbag Status Indicator – United States Passenger Airbag Status Indicator – Canada The indicator next to the passenger airbag status indicator lights is the passenger safety belt reminder light. See Passenger Safety Belt Reminder Light on page 3-60 for more information on that indicator. When the vehicle is running, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. 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. 3-61 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. Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. {CAUTION: Even though the passenger sensing system is designed to turn off the passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is failsafe, 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 1-58 for more on this, including important safety information. 3-62 If, after several seconds, all 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 for service. {CAUTION: If the off indicator and the airbag readiness light ever come on together, 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 seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 3-60. Charging System Light When you turn the engine on, this light will come on brieﬂy to show that the generator and battery charging systems are working properly. If this light stays on, your vehicle needs service. You should take your vehicle to the dealer at once. To save your battery until you get there, turn off all accessories. See DIC Controls and Displays on page 3-74 for more information. 3-63 Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part isn’t working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on, there is a brake problem. Have your brake system inspected right away. United States Canada This light should come on brieﬂy when you turn the engine on. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. When the ignition is on, the brake system warning light will also come on when you set your parking brake. The light will stay on if your parking brake does not release fully. If it stays on after your parking brake is fully released, it means you have a brake problem. If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is 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 4-37. {CAUTION: Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service. 3-64 Low Tire Pressure Warning Light This light will come on brieﬂy as you start the engine, for vehicles equipped with the Tire Pressure Monitor System. It will then come on only when a ﬂat or low tire pressure condition exists. See Tire Pressure Monitor System on page 5-67 for more information. Anti-Lock Brake System Warning Light With the anti-lock brake system, the light will come on when your engine is started and may stay on for several seconds. That is normal. If the ABS warning light comes on and stays on, there may be a problem with the antilock portion of the brake system. If the red BRAKE light is not on, you still have brakes, but you do not have antilock brakes. See Brake System Warning Light on page 3-64. If the light stays on, press the ignition button to OFF/ACC. If the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-64. 3-65 Traction Control System (TCS) Warning Light Engine Coolant Temperature Warning Light If the TC (traction control) warning light comes on and stays on, there may be a problem with the traction control system. The engine coolant temperature warning light will come on when the engine is very hot. The TC (traction control) warning light will come on brieﬂy when you turn the engine on. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. The light will also come on if you turn the traction control system off using the TC (traction control) on/off button located on the console. If the TC (traction control) warning light stays on or comes on while you are driving, pull off the road as soon as possible and stop carefully. Turn your engine off and then restart it. If the light still stays on or comes back on again while you are driving, your vehicle needs service. Have the traction control system inspected as soon as possible. See Traction Control System (TCS) on page 4-9 and StabiliTrak® System on page 4-11 for more information. Also see Competitive Driving Mode (STS-V) on page 4-10 for more information. 3-66 This light will also come 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 your vehicle to overheat, see Overheated Engine Protection Operating Mode on page 5-32. See Engine Overheating on page 5-31 and DIC Warnings and Messages on page 3-79 for more information. Engine Coolant Temperature Gage This gage shows the engine coolant temperature. It can be used to see when your engine has warmed up and to make sure your 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 will come on. See Engine Overheating on page 5-31 for more information. Malfunction Indicator Lamp Check Engine Light Your vehicle is equipped with a computer which monitors operation of the fuel, ignition, and emission control systems. This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The Check Engine light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. Notice: light on, after awhile, your emission controls may not work as well, your fuel economy may not be as good, and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty. If you keep driving your vehicle with this 3-67 If the Light Is Flashing The following may prevent more serious damage to your vehicle: (cid:127) Reducing vehicle speed (cid:127) Avoiding hard accelerations (cid:127) Avoiding steep uphill grades If the light stops ﬂashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the engine off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still ﬂashing, follow the previous steps, and see your dealer for service as soon as possible. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 5-3. This light should come on brieﬂy, as a check to show you it is working, as you start the engine. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required. 3-68 (cid:127) (cid:127) If the Light Is On Steady You also may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. 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 will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 5-5. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If none of the above steps have made the light turn off, your dealer can check the vehicle. Your dealer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that may have developed. Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. 3-69 Oil Pressure Light {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the Check Engine light is on or not working properly. 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 2-24. 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 — if you press the bottom of the ACC button only brieﬂy, less than ﬁve seconds, the accessory mode will be turned on, but not the ignition. After the bulb check, be sure to press and release the ACC button again to turn the ignition off and avoid draining the vehicle’s battery. Your vehicle will not pass this inspection if the OBD (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 you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your GM dealer can prepare the vehicle for inspection. 3-70 If equipped, this light tells you if there could be a problem with your engine oil pressure. Fog Lamp Light The fog lamps light will come on when the fog lamps are in use. This light will come on brieﬂy when you start your engine. That is a check to be sure the light works. If it does not come on, be sure to have it ﬁxed so it will be there to warn you if something goes wrong. When the light comes on and stays on, it means that oil is not ﬂowing through your engine properly. You could be low on oil and you might have some other system problem. Security Light For information regarding this light, see Theft-Deterrent System on page 2-21. The light will go out when the fog lamps are turned off. See Fog Lamps on page 3-37 for more information. Lights On Reminder This light comes on whenever the parking lamps are on. See Headlamps on Reminder on page 3-35 for more information. 3-71 Cruise Control Light Fuel Gage This light comes on whenever you set your cruise control. The fuel gage shows approximately how much fuel is in the tank. It works only when the engine is on. The light will go out when the cruise control is turned off. See Cruise Control on page 3-16 and Adaptive Cruise Control on page 3-19 for more information. Highbeam On Light This light comes on whenever the high-beam headlamps are on. See “Intellibeam™ Intelligent High-Beam Headlamp Control System” under Headlamps on page 3-31 and Headlamp High/Low-Beam Changer on page 3-8 for more information. 3-72 If the fuel supply gets low, the Full Level Low message will appear on the DIC and a single chime will sound. See DIC Warnings and Messages on page 3-79 for more information. Here are a few concerns some owners have had about the fuel gage. All of these situations are normal and do not indicate that anything is wrong with the fuel gage: (cid:127) 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. (cid:127) (cid:127) 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 Controls and Displays on page 3-74 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 (STS) on page 2-28 or Automatic Transmission Operation (STS-V) on page 2-32 for more information on the shift lever positions. 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 (STS) on page 2-28 or Automatic Transmission Operation (STS-V) on page 2-32 for more information. If a problem is detected, a warning message will appear on the display. Be sure to take any message that appears on the display seriously and remember that clearing the message will only make the message disappear, not correct the problem. 3-73 DIC Controls 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. DIC Buttons (Base Level) If your vehicle does not have a Head-Up Display (HUD), these are the buttons for your DIC. «4ª (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, if your vehicle has a tire pressure monitor (TPM) system, and engine oil life, if your vehicle has this feature. If you have an STS-V, the DIC also has additional vehicle information displays which include engine boost, engine oil temperature, oil pressure, and transmission ﬂuid temperature.

MPH (km/h) If your 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 your 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 approximately 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. 3-76 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. 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 3-63 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 for more information. Tire Pressure If your vehicle has a tire pressure monitor (TPM) system, this display shows the air pressure of each road 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, LOW will appear on the display with the value. If the tire pressure is high, HIGH will appear on the display with the value. Press the information button to scroll through the following displays: LF TIRE: This display shows the air pressure in the driver’s side front tire. RF TIRE: This display shows the air pressure in the passenger’s side front tire. LR TIRE: This display shows the air pressure in the driver’s side rear tire. RR TIRE: This display shows the air pressure in the passenger’s 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 GM dealer for service. 3-77 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. You should change your 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 5-24. 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. 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). 3-78 Trip Odometer Press the trip information button until trip odometer A or B appears on the DIC display.
