Press the button to make the front and rear turn signal lamps ﬂash on and off. Press the button again to turn the ﬂashers off. When the hazard warning ﬂashers are on, the turn signals will not work. 172 Other Warning Devices If you carry reﬂective triangles, you can set them up at the side of the road about 300 feet (100 m) behind your vehicle. Horn Press near or on the horn symbols on the steering wheel pad to sound the horn. Tilt and Telescopic Steering Wheel A tilt and telescope wheel lets you adjust the steering wheel before you drive. The steering wheel can be raised to the highest level to give your legs more room when you enter and exit the vehicle. The lever that lets you tilt and telescope the steering wheel is located on the left side of the steering column. To tilt and telescope the steering wheel, pull down the lever. Then move the steering wheel up or down or backward or forward into a comfortable position. Pull the lever up to lock the steering wheel in place. 173 Power Tilt Wheel and Telescopic Steering Column Turn Signal/Multifunction Lever If your vehicle has this feature, the power tilt wheel control is located on the left side of the steering column. To operate the power tilt feature, push the control up and the steering wheel will tilt up. Push the control down and the steering wheel will go down. Push the control forward and the steering wheel moves toward the front of the vehicle. Push the control rearward and the steering wheel moves toward the rear of the vehicle. The lever on the left side of the steering column includes the following: (cid:129) G Turn and Lane Change Signals. See Turn and Lane-Change Signals on page 175. (cid:129) 2Headlamp High/Low-Beam Changer. See Headlamp High/Low-Beam Changer on page 176. (cid:129) Flash-to-Pass. See Flash-to-Pass on page 176. (cid:129) N Windshield Wipers. See Windshield Wipers on page 176. 174 (cid:129) LQ Windshield Washer. See Windshield Washer on page 177. (cid:129) 5 Z Rear Wiper/Washer. See Rear Window Wiper/Washer on page 179. For information on the headlamps, see Exterior Lamps on page 183. Turn and Lane-Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is ﬁnished, the lever will return automatically. An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. To signal a lane change, raise or lower the lever until the arrow starts to ﬂash. Hold it there until you complete your lane change. The lever will return by itself when you release it. If you momentarily press and release the lever, the turn signal will ﬂash three times. If the arrow ﬂashes faster than normal as you signal a turn or a lane change, a signal bulb may be burned out and other drivers will not see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check for burned-out bulbs and then check the fuse. See Fuses and Circuit Breakers on page 490. Turn Signal On Chime If you leave either one of your turn signals on and drive more than 3/4 mile (1.2 km), a chime will sound to alert you. 175 Headlamp High/Low-Beam Changer To change the headlamps from low beam to high beam, push the turn signal/multifunction lever toward the front of the vehicle. This light on the instrument panel cluster comes on if the high beam lamps are turned on while the ignition is on. To change the headlamps from high beam to low beam, pull the turn signal lever toward the rear of the vehicle. Flash-to-Pass With the turn signal lever in the low-beam position, pull the lever toward you momentarily to switch to high-beam (to signal that you are going to pass). If the headlamps are on, they will return to low-beam when the lever is released. This feature operates even when the headlamps are off. Windshield Wipers Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, gently loosen or thaw them. Damaged wiper blades may not clear the windshield well, making it harder to see and drive safely. If the blades do become damaged, install new blades or blade inserts. For more information, see Windshield Wiper Blade Replacement on page 434. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. Clear away snow or ice to prevent an overload. 176 The windshield wipers are controlled by turning the band with the wiper symbol. 8(Mist): Turn the band to mist for a single wiping cycle. Hold it there until the wipers start. Then let go. The wipers will stop after one wipe. Hold the band on mist longer, for more wipe cycles. 9(Off): To stop the wipers, move the band to off. 6 (Delay): The wiper speed can be set for a long or short delay between wiping cycles. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay. 6 (Low Speed): Turn the band away from you to the ﬁrst solid band past the delay settings, for steady wiping at low speed. ? (High Speed): Turn the band further, to the second solid band past the delay settings, for high-speed wiping. Windshield Washer J (Washer Fluid): Press and release this paddle, located at the top of the turn signal/ multifunction lever, to spray washer ﬂuid on the windshield. The wipers clear the windshield and either stop or return to the preset speed. The ignition key must be in ACCESSORY or ON for this to work. See Windshield Washer Fluid on page 420 Windshield Washer Fluid. {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. WASHER FLUID LOW ADD FLUID is displayed on the Driver Information Center (DIC) when the washer ﬂuid is low. See DIC Warnings and Messages on page 244. 177 Heated Windshield Washer If your vehicle has the heated windshield washer ﬂuid system it can be used to help clear ice, snow, tree sap, or bugs from the windshield. This feature only works with the front wiper system, not the rear wiper system. The button is located to the left of the steering column on the instrument panel. Push the heated washer ﬂuid button to activate the heated windshield washer ﬂuid system. This activation begins four heated wash/wipe cycles. The ﬁrst heated wash/wipe cycle can take up to 40 seconds to occur, depending on outside temperature. After the ﬁrst wash/wipe cycle, it can take up to 20 seconds for each of the remaining cycles. Press the button again to turn off the heated windshield washer ﬂuid system or it will automatically turn off after four wipe cycles have been completed. When the heated windshield washer ﬂuid system is activated under certain outside temperature conditions, steam might ﬂow out of the washer nozzles for a short period of time before washer ﬂuid is sprayed. This is a normal condition. WASHER FLUID LOW ADD FLUID is displayed on the DIC when the washer ﬂuid is low. See DIC Warnings and Messages on page 244. 178 Rear Window Wiper/Washer {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. The rear wiper control is located on the turn signal/multifunction lever. To turn the rear wiper on, slide the lever to a wiper position. 9(Off): Slide the lever to this setting to turn the wiper off. 5 (Rear Wiper Delay): Slide the lever to this setting to turn on the rear wiper delay. Z (Rear Wiper): Slide the lever to this setting to turn on the rear wiper. = (Rear Wiper Wash): Push the button on the end of the turn signal/multifunction lever to spray washer ﬂuid on the rear window. The wipers will clear the rear window and either stop or return to your preset speed. For more washer cycles, press and hold the button. 179 Cruise Control With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). When you apply your brakes, cruise control is turned off. {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. 180 The cruise control buttons are located on left side of the steering wheel. T (On/Off): Press this button to turn cruise control on and off. The indicator comes on when cruise control is on. + RES (Resume/Accelerate): Press this button to make the vehicle accelerate or resume to a previously set speed. SET–: Press this button to set the speed or make the vehicle decelerate. [ (Cancel): Press this button to cancel cruise control. Setting Cruise Control Cruise control will not work if your parking brake is set, or if the master cylinder brake ﬂuid level is low. The cruise control light on the instrument panel cluster comes on after the cruise control has been set to the desired speed. {CAUTION: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. 1. Press the cruise control on/off button. 2. Get up to the speed desired. 3. Press and release the SET– button located on the steering wheel. 4. Take your foot off the accelerator. Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This shuts off the cruise control. But you do not need to reset it. Once you are driving about 25 mph (40 km/h) or more, press the +RES button on your steering wheel. The vehicle will go back to the previously chosen speed and stay there. Increasing Speed While Using Cruise Control To increase the cruise speed while using cruise control: (cid:129) Press and hold the +RES button on the steering wheel until you reach the desired speed, then release it. (cid:129) To increase vehicle speed in small increments, press the +RES button. 181 Reducing Speed While Using Cruise Control To reduce your speed while using cruise control: (cid:129) Press and hold the SET– button on the steering wheel until you reach the lower speed desired, then release it. (cid:129) To slow down in very small amounts, press the SET– button on the steering wheel brieﬂy. Each time this is done, the vehicle will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase vehicle speed. When you take your foot off the pedal, your vehicle will slow down to the previously set cruise speed. 182 Using Cruise Control on Hills How well your cruise control will work on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle speed down. Of course, applying the brake turns off the cruise control. Many drivers ﬁnd this to be too much trouble and do not use cruise control on steep hills. Ending Cruise Control There are three ways to end cruise control: (cid:129) Step lightly on the brake pedal. (cid:129) Press the [ (cancel) button on the steering (cid:129) Press the T (on/off) button on the steering wheel. wheel. Erasing Speed Memory The cruise control set speed memory is erased by turning off the cruise control or the ignition. Exterior Lamps The exterior lamps control is located on the instrument panel to the left of the steering wheel. It controls the following systems: (cid:129) Headlamps (cid:129) Taillamps (cid:129) Parking Lamps License Plate Lamps Instrument Panel Lights (cid:129) Fog Lamps The exterior lamps control has four positions: O (Off): Brieﬂy turn the control to this position to turn off the automatic light control. Brieﬂy turn to this position again to turn automatic light control on again. AUTO (Automatic): Turn the control to this position to automatically turn on the headlamps at normal brightness, together with the following: (cid:129) Parking Lamps (cid:129) Taillamps License Plate Lamps Instrument Panel Lights ; (Parking Lamps): Turn the control to this position to turn on the parking lamps together with the following: (cid:129) Taillamps License Plate Lamps Instrument Panel Lights 183 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) 2(Headlamps): Turn the control to this position to turn on the headlamps together with the following lamps listed below. A warning chime will sound if you open the driver’s door when the ignition switch is off and the headlamps are on. (cid:129) Parking Lamps (cid:129) Taillamps License Plate Lamps Instrument Panel Lights - (Fog Lamps): Push the fog lamps control in to turn on the fog lamps. See Fog Lamps on page 186. Delayed Headlamps The delayed headlamps feature provides a period of exterior lighting as you leave the area around your vehicle. The feature is activated when the headlamps are on due to the automatic headlamps control feature described previously in this section, and when the ignition is turned off. Your headlamps will then remain on until the exterior lamps control is moved to the parking lamps position or until the pre-selected delayed headlamp lighting period has ended. If you turn off the ignition with the headlamps switch in the parking lamps or headlamps position, the delayed headlamps cycle will not occur. To disable the delayed headlamps feature or change the time of delay, see DIC Vehicle Customization (With DIC Buttons) on page 255. 184 (cid:129) (cid:129) Daytime Running Lamps (DRL)/ Automatic Headlamp System 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. A light sensor on top of the instrument panel makes the DRL work, so be sure it is not covered. The DRL system’s automatic headlamp control will make the low-beam headlamps come on at a reduced brightness when the following conditions are met: (cid:129) The ignition is in the ON position. (cid:129) The exterior lamps control is in AUTO. (cid:129) The engine is running. When the DRL are on, only the low-beam headlamps, at a reduced level of brightness, will be on. The headlamps, taillamps, sidemarker, and other lamps will not be on. The instrument panel and cluster will also not be lit. When it is dark enough outside, the low-beam headlamps will turn off and the headlamps and parking lamps will turn on. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will come on. As with any vehicle, you should turn on the regular headlamp system when it is needed. 185 Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. - (Fog Lamps): The fog lamps button is located on the exterior lamps control. The exterior lamps control is located on the instrument panel to the left of the steering column. The ignition must be on for the fog lamps to work. Press the exterior lamps button to turn the fog lamps on or off. A light will come on in the instrument panel cluster when the fog lamps are in use. When the headlamps are changed to high-beam, the fog lamps will turn off. The fog lamps come back on again when the high-beam headlamps are turned off. Some localities have laws that require the headlamps to be on along with the fog lamps. Instrument Panel Brightness D (Instrument Panel Brightness): The knob with this symbol on it is located next to the exterior lamps control. Push the knob in all the way until it pops out and then turn the knob clockwise to brighten or counterclockwise to dim the lights. Push the knob back in when ﬁnished. Courtesy Lamps When a door is opened, the courtesy lamps automatically come on. They make it easy for you to enter and leave your vehicle. You can also manually turn these lamps on by fully turning the instrument panel brightness control clockwise. The reading lamps, located on the headliner, can be turned on or off independent of the automatic courtesy lamps, when the doors are closed. 186 Entry Lighting Your vehicle may have courtesy lamps that will come on and stay on for a set time whenever the unlock symbol is pressed on the Remote Keyless Entry (RKE) Transmitter, if the vehicle has one. If a door is opened, the lamps will stay on while it is open and then turn off automatically about 25 seconds after the door is closed. If the unlock symbol is pressed and you do not open a door, the lamps will turn off after about 20 seconds. Entry lighting includes a feature called theater dimming. With theater dimming, the lamps do not turn off at the end of the delay time. Instead, they slowly dim after the delay time until they go out. The delay time is canceled if you turn the ignition key to ON or press the power door lock switch. The lamps will dim right away. When the ignition is on, illuminated entry is inactive, which means the courtesy lamps will not come on unless a door is opened. Delayed Entry Lighting Delayed entry lighting illuminates the interior for a period of time after all the doors have been closed. The ignition must be off for delayed entry lighting to work. Immediately after all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs: (cid:129) The ignition is in ON. (cid:129) The doors are locked. (cid:129) An illumination period of 25 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on because a door is open. 187 Delayed Exit Lighting This feature illuminates the interior for a period of time after the key is removed from the ignition. The ignition must be off for delayed exit lighting to work. When the key is removed, interior illumination will activate and remain on until one of the following occurs: (cid:129) The ignition is in ON. (cid:129) The power door locks are activated. (cid:129) An illumination period of 20 seconds has elapsed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on because a door is open. Parade Dimming The instrument panel has an added feature called parade mode. It automatically prohibits the dimming of the instrument panel displays during the daylight while the headlamps are on so that you will still be able to see the displays. Reading Lamps The vehicle has reading lamps that also act as the dome lamp. Press the button to turn them on and off. 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 put the charge back in. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or 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. 188 A high electrical load occurs when several of the following loads 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 244. Battery Run-Down Protection This vehicle has a feature to help prevent the battery from being drained, if the interior courtesy lamps, reading/map lamps, visor vanity lamps or trunk lamp are accidentally left on. If any of these lamps are left on, they will automatically turn off after 10 minutes, if the ignition is off. The lamps will not come back on again until one of the following occurs: (cid:129) The ignition is turned on. (cid:129) The exterior lamps control is turned off, then on again. The headlamps will timeout after 10 minutes, if they are manually turned on before the ignition is off. 189 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 the vehicle has the Head-Up Display (HUD), some information concerning the operation of the vehicle is projected onto the windshield. This includes the speedometer reading, RPM reading, transmission position, outside air temperature, the tap shift gear, and a brief display of the current radio station, including XM information or CD track. It will also display turn-by-turn navigation information if the vehicle has a navigation radio. The images are projected by the HUD lens located on the driver’s side of the instrument panel. The tap shift gear will also appear on the HUD if the vehicle has tap shift and it is active. The HUD information can be displayed in one of three languages, English, French, or Spanish. The speedometer reading and other numerical values can be displayed in either English or metric units. The language selection and the units of measurement are changed through the trip computer in the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 255. 190 If you try to use the HUD image as a The HUD will temporarily display CHECK GAGES and ICE POSSIBLE when there are messages on the DIC trip computer. The HUD will also display the following messages when these systems are active: (cid:129) TRACTION CONTROL ACTIVE (cid:129) STABILITRAK ACTIVE Notice: parking aid, you may misjudge the distance and damage your vehicle. Do not use the HUD image as a parking aid. When the HUD is on, the speedometer reading will continually be displayed. The current radio station or CD track number will display for a short period of time after the radio or CD track status changes. This will happen whenever radio information is changed. The speedometer size will be reduced when radio, CD information, warnings, or turn-by-turn navigation information are displayed on the HUD. 191 The HUD information appears as an image focused out toward the front of the vehicle. When the ignition key is turned to RUN, the HUD will display an introductory message for a short time, until the HUD is ready. The following indicator lights come on the instrument panel when activated and will also appear on the HUD: (cid:129) Turn Signal Indicators (cid:129) High-Beam Indicator Symbol The HUD control is located to the right of the steering wheel. To adjust the HUD image so that items are properly displayed, do the following: 1. Adjust the driver’s seat to a comfortable position. 2. Start the engine. 3. Adjust the HUD controls. Use the following settings to adjust the HUD. 9(Off): To turn HUD off, rotate the dimming knob fully counterclockwise until the HUD display turns off. 192 Brightness: Turn the knob on the HUD control clockwise to brighten the display and counterclockwise to dim it. w (Up): x (Down): Press the up or down arrows to center the HUD image in your view. The HUD image can only be adjusted up and down, not side to side. ? (Page): Press this button to select the display formats. Release the page button when the format number with the desired display is shown on the HUD. The three formats are as follows: Format One: This display gives the speedometer reading (in English or metric units), turn signal indication, high beam indication, transmission positions, and the outside air temperature. Format Two: This display includes the information in Format One without the transmission information and the outside air temperature. Format Three: This display includes all the information in Format One along with a circular tachometer, but without outside air temperature. All formats will show the turn-by-turn navigation information and provide details about the next driving maneuver to be made. When you near your destination, the HUD will display a distance bar that will ﬁll in the closer you get to your destination. All navigation information is provided to the HUD by the navigation radio, if the vehicle has one. The HUD image displayed on the windshield will automatically dim and brighten to compensate for outside lighting. The HUD image can temporarily light up depending on the angle and position of the sunlight on the HUD display. This is normal and will change when the angle of the sunlight on the HUD display changes. Polarized sunglasses could make the HUD image harder to see. Care of the HUD Clean the inside of the windshield as needed to remove any dirt or ﬁlm that could reduce the sharpness or clarity of the HUD image. To clean the HUD lens, use a soft, clean cloth that has household glass cleaner sprayed on it. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit. 193 Ultrasonic Rear Parking Assist (URPA) If your vehicle has the Ultrasonic Rear Parking Assist (URPA) system it is designed to help you park while in Reverse (R). It operates only at speeds less than 5 mph (8 km/h). URPA helps make parking easier and helps you avoid colliding with objects such as parked vehicles. The URPA system detects objects that are close to the rear of the vehicle which are at least 10 inches (25.4 cm) off the ground and below hood or trunk level. The system detects objects up to 8 feet (2.5 m) behind your vehicle. The URPA sensors determine how close these objects are from your bumper within this area. If You Cannot See the HUD Image When the Ignition Is On Is anything covering the HUD lens? Is the HUD dimmer setting bright enough? Is the HUD image adjusted to the proper height? (cid:129) Are you wearing polarized sunglasses? (cid:129) Still no HUD image? Check the fuse in the instrument panel fuse block. See Instrument Panel Fuse Block on page 490. If the HUD Image Is Not Clear Is the HUD image too bright? (cid:129) Are the windshield and HUD lens clean? If the HUD image is not correct, contact your dealer/retailer. Keep in mind that the windshield is part of the HUD system. 194 (cid:129) (cid:129) (cid:129) (cid:129) {CAUTION: The Ultrasonic Rear Park Assist (URPA) system does not replace driver vision. URPA does not: (cid:129) Operate above speeds of 5 mph (8 km/h). (cid:129) Detect objects more than 8 feet (2.5 meters) behind the vehicle. This distance may be less during warmer or humid weather. (cid:129) Detect objects that are below the bumper, underneath the vehicle, or that are very close to the vehicle. (cid:129) Detect children, pedestrians, bicyclists, or pets. So if you do not use proper care before backing up, you could hit a vehicle, child, pedestrian, bicyclist, or pet, resulting in vehicle damage, injury, or death. Even though the vehicle has the URPA system, always check carefully before backing up by checking behind your vehicle. The URPA display is located in the headliner and can be seen by looking over your right shoulder. The URPA display has three color-coded lights. The lights are used to provide distance and system information, along with beeps that will be heard through the speakers. The red light in the URPA display will be lit if the vehicle is in REVERSE (R). If the vehicle has a Driver Information Center (DIC), PARK ASSIST OFF will display on the DIC when the vehicle has been started and shifted out of PARK (P). See DIC Warnings and Messages on page 244 for more information. How the System Works When the shift lever is moved into REVERSE (R), the rear display will brieﬂy come on to let you know the display is operating correctly. URPA comes on automatically when the shift lever is moved into REVERSE (R). 195 The system does not work at a reverse speed greater than 5 mph (8 km/h). To remind you of this, the red light on the rear display will ﬂash. To disable URPA, see DIC Operation and Displays (With DIC Buttons) on page 233 and DIC Operations and Displays (Without DIC Buttons) on page 239. URPA automatically turns back on each time the vehicle is started. How the System Works when Backing If the shift lever is in REVERSE (R), URPA detects objects close to the rear bumper. The ﬁrst time an object is detected a single beep will sound. If an object is detected at a REVERSE (R) speed between 0 mph (0 km/h) and 5 mph (8 km/h), the following describes what will occur based on your distance to a detected object located behind the vehicle: (cid:129) At distances between 40 inches (1 m) and 8 ft (2.5 m), a single amber light will come on. (cid:129) At distances between 23 inches (0.6 m) and 40 inches (1 m), both amber lights will be on. 196 (cid:129) At distances between 12 inches (0.3 m) and 23 inches (0.6 m), all three lights (amber/ amber/red) will be on. (cid:129) At distances less than 12 inches (0.3 m), a beeping sound will repeat for a short time and all three lights (amber/amber/red) will ﬂash. When the System Does Not Seem to Work Properly If the URPA system will not activate due to a temporary condition, the message PARK ASSIST OFF will display on the DIC screen and a red light will come on the URPA display when the shift lever is moved into REVERSE (R). This occurs under the following conditions: (cid:129) The parking brake pedal is depressed. (cid:129) A trailer was attached to your vehicle, or a bicycle or an object was hanging out of your trunk during your last drive when you turned off the vehicle. If the attached objects are removed from your vehicle before the start of your next drive, the system will return to normal operation unless an object is detected when the vehicle is shifted into REVERSE (R). Accessory Power Outlet(s) The accessory power outlets can be used to connect electrical equipment such as a cellular phone or CB radio. Your vehicle may have four accessory power outlets. They are located on the instrument panel below the climate controls, inside the front center console storage bin, at the rear of the center console, and in the rear cargo area. To use the outlets, remove the cover. When not in use, always cover the outlet 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 of 20 amperes. If this occurs, URPA assumes the object is still attached, so you will have to wait until the vehicle is driven forward above 15 mph (25 km/h) before URPA will return to normal operation. (cid:129) The ultrasonic sensors need to be kept clean. So, be sure to keep your vehicle’s rear bumper free of mud, dirt, snow, ice, and slush. For cleaning instructions, see Washing Your Vehicle on page 482. If the DIC still displays the PARK ASSIST OFF message after cleaning the bumper and driving forward at a speed of at least 15 mph (25 km/h), see your dealer/retailer. (cid:129) Other conditions that may affect system performance include vibrations from a jackhammer or the compression of air brakes on a very large truck or other mechanical devices that interfere with URPA performance. As always, drivers should use care when backing up a vehicle. Always look behind you, being sure to check for other vehicles, obstructions and blind spots. If the vehicle bumper is damaged, the URPA system may not work properly. Take the vehicle to your dealer/retailer to repair the system. 197 Power Outlet 115 Volt Alternating Current Your vehicle may have a power outlet that can be used to plug in auxiliary electrical equipment with a maximum limit of 150 watts. If you try to use equipment that requires more than the limit, a protection circuit will cut the power supply. To reset the outlet, unplug the item and plug it back in or turn the ignition to LOCK or ACCESSORY and then back on. The power will automatically restart when equipment that operates within the limit is plugged into the outlet. The power outlet is located on the rear of the center console. Certain electrical accessories may not be compatible with the accessory power outlets and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/ retailer for additional information on the accessory power outlet. 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 of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the installation instructions included with the equipment. Notice: Improper use of the power outlet can cause 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. 198 The indicator on the inner outlet face will come on when 115 volt AC power is available. The AC power is available when the ignition is turned to ACCESSORY or ON, and electrical equipment is plugged into the outlet. The AC power is not available in the outlet when the ignition is turned to OFF. The power outlet is not designed for the following electrical equipment and may not work properly if these items are plugged into the power outlet: (cid:129) Equipment with high initial peak wattage such as: compressor-driven refrigerators and electric power tools. (cid:129) Other equipment requiring an extremely stable power supply such as: microcomputer-controlled electric blankets, touch sensor lamps, etc. See High Voltage Devices and Wiring on page 489. Climate Controls Climate Control System With this system you can control the heating, cooling, defrost, defog, and ventilation of the vehicle. Manual Operation 9 (Fan): Turn the left knob clockwise or counterclockwise to increase or decrease the fan speed. Turn the knob all the way counterclockwise to turn the front system off. 199 Temperature Control: Turn the center knob clockwise or counterclockwise to increase or decrease the temperature of the air ﬂowing from the system. Airﬂow Mode Control: Turn the right knob clockwise or counterclockwise to direct the airﬂow inside of the vehicle. To change the current mode, select one of the following: H (Vent): This mode directs air to the instrument panel outlets. ) (Bi-Level): This mode directs about half of the air to the instrument panel outlets and half to the ﬂoor outlets. A little air is directed towards the windshield and side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. 6 (Floor): This mode directs most of the air to the ﬂoor outlets, with some of the air directed to the windshield, side window outlets, and second row ﬂoor outlets. In this mode, the system automatically selects outside air. Recirculation cannot be selected when in Floor Mode. 200 The right knob can also be used to select defog or defrost mode. For more information, see “Defogging and Defrosting” later in this section. By positioning the right knob between two modes, a combination of those two modes is selected. @ (Recirculation): Press this button to turn the recirculation mode on or off. The indicator light on the button turns on when this mode is selected. This mode keeps outside air from entering the vehicle. It can be used to reduce the outside air and odors entering the vehicle. Recirculation may also help cool the air inside the vehicle more quickly once the temperature inside the vehicle is less than the outside temperature. The recirculation mode can be turned off in vent and bi-level modes by pressing the button again. Recirculation mode automatically turns off when the engine is turned off and must be re-selected when the engine is turned on again. The recirculation mode cannot be used with ﬂoor, defrost, or defogging modes. If you try to select recirculation in one of those modes, the indicator ﬂashes three times and turns off. The air conditioning compressor also comes on when this mode is activated unless the outside air temperature is less than 40°F (4°C). While in recirculation mode the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase the fan speed. # (Air Conditioning): Press this button on the left knob to turn the air conditioning system on or off. When A/C is pressed, an indicator light comes on to show that the air conditioning has been activated. The air conditioning compressor does not operate when outside temperatures fall below 40°F (4°C). The indicator light ﬂashes three times and turns off when outside conditions affect air conditioning operation. This is normal. For quicker cool down on hot days, do the following: 1. Open the windows to let hot air escape. 2. Select the vent mode. 3. Select the air conditioner. 4. Select the coolest temperature. 5. Select the highest fan speed. 6. Close the windows after the hot air has escaped. 7. Once the vehicle’s interior temperature is below the outside temperature, select recirculation mode for better cooling. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. Using recirculation for long periods of time may cause the air inside of the vehicle to become too dry. To prevent this from happening, after the inside of the vehicle has cooled, turn the recirculation mode off. The air conditioning system removes moisture from the air, so you might notice a small amount of water dripping underneath the front of center and right rear of the vehicle while idling or after turning off the engine. This is normal. 201 Defogging and Defrosting Fog on the inside of the 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 or frost from the windshield. Turn the right knob clockwise to select the defog or defrost mode. - (Defog): The defog mode is used to clear the windows of fog or moisture and warm the passengers. This mode directs air to the windshield, ﬂoor outlets, and side window vents. When you select this mode, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is less than 40°F (4°C). The recirculation mode cannot be selected while in the defog mode. Do not drive the vehicle until all the windows are clear. 0(Defrost): The defrost mode is used to remove fog or frost from the windshield more quickly. This mode directs most of the air to the windshield and side window vents and some to the ﬂoor vents. In this mode, the system will automatically force outside air into your vehicle. The recirculation mode cannot be selected while in the defrost mode. The air conditioning compressor will run automatically in this setting, unless the outside temperature is less than 40°F (4°C). Do not drive the vehicle until all the windows are clear. AUX (Auxiliary): Press this button to turn the rear heating and air conditioning on. See Rear Air Conditioning and Heating System on page 211 or Rear Air Conditioning and Heating System and Electronic Climate Controls on page 212. 202 Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear Window Defogger): Press this button on the right knob to turn the rear window defogger on or off. The rear window defogger stays on about 10 minutes after the button is pressed, before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all the windows are clear. If your vehicle has heated outside rearview mirrors, the mirrors heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. Dual Automatic Climate Control System With this system, you can control the heating, cooling, and ventilation in your vehicle. Your vehicle also has a ﬂow-through ventilation system described later in this section. You can select different climate control temperature settings for the driver and passengers. 203 Driver’s Side Temperature Control The driver side temperature buttons are used to adjust the temperature of the air coming through the system on the driver side. The temperature can be adjusted even if the system is turned off. This is possible since outside air will always ﬂow through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section. Press the + or − buttons to increase or decrease the temperature. The driver side temperature display will show the temperature setting decreasing or increasing. Passenger’s Side Temperature Control The passenger’s temperature buttons can be used to change the temperature of the air coming through the system on the passenger side of the vehicle. The temperature can be adjusted even if the system is turned off. This is possible since outside air will always ﬂow through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section. 204 Press the + or − buttons to increase or decrease the temperature. The passenger side display will show the temperature setting decreasing or increasing. The passenger’s temperature setting can be set to match the driver’s temperature setting by pressing the PASS button and turning off the PASS indicator. When the passenger’s temperature setting is set different than the driver’s setting, the indicator on the PASS button comes on and both the driver side and passenger side temperature displays are shown. Automatic Operation AUTO (Automatic): When automatic operation is active the system controls the inside temperature, the air delivery, and the fan speed. Use the steps below to place the entire system in automatic mode: 1. Press the AUTO button. When AUTO is selected, the display shows the current temperature(s) selected and AUTO is on the display. The current delivery mode and fan speed also display for approximately 5 seconds. When AUTO is selected, the air conditioning operation and air inlet are automatically controlled. The air conditioning compressor runs when the outside temperature is over about 40°F (4°C). The air inlet is normally set to outside air. If it is hot outside, the air inlet can automatically switch to recirculate inside air to help quickly cool down your vehicle. The light comes on the recirculation button while in recirculation. 2. Set the driver’s and passenger’s temperature. To ﬁnd your comfort setting, start with a 73°F (23°C) temperature setting and allow about 20 minutes for the system to regulate. Use the driver’s or passenger’s temperature buttons to adjust the temperature setting as necessary. If you choose the temperature setting of 60°F (15°C), the system remains at the maximum cooling setting. If you choose the temperature setting of 90°F (32°C), the system remains at the maximum heat setting. Choosing either maximum setting will not cause the vehicle to heat or cool any faster. Do not cover the solar sensor located on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load and also turns on your vehicle’s headlamps. For more information on the solar sensor, see “Sensors” later in this section. To avoid blowing cold air in cold weather, the system delays turning on the fan until warm air is available. The length of delay depends on the engine coolant temperature. Press the fan switch to override this delay and change the fan to a selected speed. O (On/Off): Press this button to turn off the climate control system. Outside air still enters the vehicle, and is directed to the ﬂoor. This direction can be changed by pressing the mode button. Recirculation can only be selected in vent or bi-level mode. The temperature can also be adjusted using either temperature button. If you adjust the air delivery mode or temperature settings with the system off, the display comes on brieﬂy to show the settings and then turns off. Press the on/off button or the up down arrows on the fan switch, the defrost button, AUTO button, or the air conditioning button to turn the system on when it is off. 205 Manual Operation The air delivery mode or fan speed can be manually adjusted. DC (Fan): The buttons with the fan symbols let you manually adjust the fan speed. Press the up arrow to increase fan speed and the down arrow to decrease fan speed. Pressing a fan button while the system is off will turn the system on. Pressing a fan button while in automatic control places the fan under manual control. The fan setting remains displayed and the AUTO light turns off. The air delivery mode remains in automatic control. yN z (Mode): Press the mode up and down buttons to manually change the direction of the airﬂow in the vehicle. Repeatedly press the button until the desired mode appears on the display. Pressing a mode button while the system is off will change air delivery mode without turning the system on. Press one of these buttons while in automatic control to place the mode under manual control. The air delivery mode setting displays and the AUTO light turns off. The fan remains under automatic control. H (Vent): This setting delivers air to the instrument panel outlets. ) (Bi-Level): This mode directs air to the instrument panel outlets and to the ﬂoor outlets. A little air is directed towards the windshield and side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. 6 (Floor): This mode directs most of the air to the ﬂoor outlets, with some of the air directed to the windshield, side window outlets, and second row ﬂoor outlets. In this mode, the system automatically selects outside air. Recirculation cannot be selected in ﬂoor mode. - (Defog): See “Defogging and Defrosting” later in this section. @ (Recirculation): Press this button to turn the recirculation mode on. When the button is pressed, an indicator light comes on. 206 This mode keeps outside air from entering the vehicle. It can be used to reduce outside air and prevent odors from entering your vehicle. Recirculation can also help cool the air inside your vehicle more quickly once the temperature inside the vehicle is less than the outside temperature. The recirculation mode cannot be used with ﬂoor, defrost, or defogging modes. If you try to select recirculation in one of those modes, the indicator ﬂashes three times and turns off. The air conditioning compressor also comes on when this mode is activated. While in recirculation mode the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase the fan speed. Press the button again to turn off the recirculation mode. It automatically turns off when the engine is turned off and must be re-selected when the engine is turned on again. Air Conditioning # (Air Conditioning): Press this button to turn the air conditioning (A/C) compressor on and off. When air conditioning is selected, an indicator light comes on to let you know that the air conditioning has been activated. The air conditioning compressor does not work when outside temperatures fall below 40°F (4°C). Pressing this button when the outside temperature is too cool makes the air conditioning indicator ﬂash three times and turn off to let you know the air conditioning mode is not available. If the air conditioning is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the air conditioning light turns off to show that the air conditioning mode has been canceled. On hot days, open the windows long enough to let hot inside air escape. This helps to reduce the time it takes for your vehicle to cool down. It also helps the system to operate more efficiently. The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. 207 Sensors The solar sensor, located in the defrost grille in the middle of the instrument panel, monitors the solar radiation. Do not cover the solar sensor or the system will not work properly. The interior temperature sensor located on the instrument panel to the right of the steering column, measures the temperature of the air inside the vehicle. There is also an exterior temperature sensor located behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false reading in the displayed temperature. 208 The climate control system uses the information from these sensors to maintain your comfort setting by adjusting the outlet temperature, fan speed, and the air delivery mode. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures. Defogging and Defrosting Fog on the inside of the 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 or frost from your windshield. Use the mode up and down arrows to select the defog mode. Use the defrost button to select the defrost mode. - (Defog): The defog mode is used to clear the windows of fog or moisture and warm the passengers. This mode directs air to the windshield, ﬂoor outlets, and side window vents. When you select this mode, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is close to freezing. The recirculation mode cannot be selected while in the defog mode. Do not drive the vehicle until all the windows are clear. 0(Defrost): Press this button to remove fog or frost from the windshield more quickly. This mode directs most of the air to the windshield and side window vents and some to the ﬂoor vents. In this mode, the system automatically forces outside air into your vehicle. The recirculation mode cannot be selected while in the defrost mode. The air conditioning compressor runs automatically in this setting, unless the outside temperature is close to freezing. Do not drive the vehicle until all the windows are clear. 209 Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear Window Defogger): Press this button to turn the rear window defogger on or off. The rear window defogger stays on for about 10 minutes after the button is pressed, before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all the windows are clear. If your vehicle has heated outside rearview mirrors, the mirrors will heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. 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. Outlet Adjustment Use the slider switch in the center of the outlet, to change the direction of the air ﬂow. Use the thumbwheel near the outlet to control the amount of air ﬂow or to shut off the airﬂow completely. Keep all outlets open whenever possible for best system performance. Operation Tips (cid:129) Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that can block the ﬂow of air into the vehicle. (cid:129) Use of non-GM approved hood deﬂectors can adversely affect the performance of the system. (cid:129) Keep the path under all seats clear of objects to help circulate the air inside the vehicle more effectively. If fogging reoccurs while in vent or bi-level modes with mild temperature throughout the vehicle, turn on the air conditioner to reduce windshield fogging. 210 (cid:129) Rear Air Conditioning and Heating System If your vehicle has this system, the rear controls are three knobs located on the rear of the center console. The system can be controlled from the front controls as well as the rear controls. To turn the system on, press the AUX button on the front climate control system, an indicator will be lit. Pressing the AUX button the ﬁrst time will turn the rear system on in a mimic mode. In this mode, the airﬂow in the rear will be approximately the same direction, temperature, and fan speed as the front. Pressing the AUX button again will turn the rear system and the indicator off. If the rear controls are adjusted, the system turns on in a rear independent mode. Airﬂow in the rear will then be directed according to the settings of the rear controls. The rear system can be turned off by pressing the AUX button on the front climate control system and the indicator will turn off. The system can be turned back on, by adjusting any of the rear air conditioning control knobs. Fan Knob Turn the left knob clockwise or counterclockwise to increase or decrease the fan speed. Turn the knob all the way counterclockwise to turn the rear system off. Temperature Knob The middle knob on the control panel lets you select the temperature of the air ﬂowing into the passenger area. Turn the knob clockwise or counterclockwise for warmer or cooler air. 211 Mode Knob The right knob on the control panel lets you choose the direction of the air ﬂow. H (Vent): This setting directs the air through the headliner outlets. ) (Bi-Level): This setting directs the air through the rear ﬂoor outlets under the third row seat, as well as the headliner outlets. The ﬂow can be divided between headliner and ﬂoor outlets depending upon where the knob is placed between the settings. 6(Floor): This setting directs the air through the ﬂoor outlets. The rear system ﬂoor outlets are located under the third row seats. Rear Air Conditioning and Heating System and Electronic Climate Controls If your vehicle has this rear climate control system there are rear seat audio controls located in the center console. The rear system can be controlled through the AUX button on the front climate control panel. Press the AUX button to turn the rear climate control system on or off. An indicator light near the AUX button comes on when the rear climate control system is on. The direction, temperature, and speed of the airﬂow for the rear of the vehicle will be the same as those set for the front of the vehicle. Use the controls located in the rear of the front console, to independently control the air ﬂow for the rear of the vehicle separately from that of the front of the vehicle. To turn the system on, press any of the rear air conditioning control buttons. To turn the system off, press and hold the C button. 212 Rear Climate Control with Rear Seat Audio Controls Manual Operation DC (Fan): The fan buttons on the rear seat audio control panel let you manually adjust the fan speed.

The rear system ﬂoor outlets are located under the third row seats. 213 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 is a problem with your vehicle. When one of the warning lights comes on and stays on as 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. Please follow this manual’s advice. Waiting to do repairs can be costly and even dangerous. So please get to know your vehicle’s warning lights and gages. They can be a big help. Warning Lights, Gages, and Indicators This part describes the warning lights and gages on your vehicle. The pictures help to 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 the 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 the details show on the next few pages, some warning lights come on brieﬂy when you start the engine just to let you know they are working. If you are familiar with this section, you should not be alarmed when this happens. 214 Instrument Panel Cluster The instrument cluster is designed to let you know at a glance how the vehicle is running. You will know how fast you are going, about how much fuel you have used, and many other things you will need to know to drive safely and economically. United States version shown, Canada similar 215 Speedometer and Odometer The speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). The odometer shows how far your vehicle has been driven, in either miles or kilometers. Your vehicle has a tamper-resistant odometer. If your vehicle needs a new odometer installed, the new one will be set to the mileage total of the old odometer. If this is not possible, it will be set at zero and a label must be put on the driver’s door to show the old mileage reading when the new odometer was installed. If the mileage is unknown, the label should then indicate “previous mileage unknown”. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). Safety Belt Reminder Light When the key is turned to ON or START, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled. The safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light is repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is already buckled, neither the chime nor the light will come on. 216 Passenger Safety Belt Reminder Light Several seconds after the key is turned to ON or 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 85 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. Airbag Readiness Light There is an airbag readiness light on the instrument panel cluster, 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 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 76. This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. 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. 217 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. Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your instrument panel has a passenger airbag status indicator. {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 ignition key to 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. 218 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. 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 and seat-mounted side impact airbags. 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 and seat-mounted side impact airbag are 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 and seat-mounted side impact airbag (if equipped). 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 and seat-mounted side impact airbag (if equipped) 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 a rear seat, even if the airbag is or airbags are off. If the word OFF or the off symbol is lit on the passenger airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag and seat-mounted side impact airbag. See Passenger Sensing System on page 85 for more on this, including important safety information. 219 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. {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 217 for more on this, including important safety information. 220 Charging System Light The charging system light will come on brieﬂy when you turn on the ignition, but the engine is not running, as a check to show you it is working. It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. It could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. Driving while this light is on could drain your battery. When this light comes on, the Driver Information Center (DIC) will also display the SERVICE BATTERY CHARGING SYSTEM message. See DIC Warnings and Messages on page 244 for more information. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner. Voltmeter Gage When the engine is not running, but the ignition is turned to ON, this gage shows the battery’s state of charge in DC volts. When the engine is running, this gage shows the condition of the charging system. The vehicle’s charging system regulates voltage based on the state of charge of the battery. The voltmeter may ﬂuctuate. This is normal. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. If there is a problem with the battery charging system, a SERVICE BATTERY CHARGING SYSTEM message will appear in the Driver Information Center (DIC) and/or the charging system light will come on. See DIC Warnings and Messages on page 244 and Charging System Light on page 220 for more information. However, readings in either warning zone may indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. 221 Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part is not 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 ignition key to ON. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. This light may also come on due to low brake ﬂuid. See Brakes on page 421 for more information. 222 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. Make sure the parking brake is fully released. 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 367. {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. Anti-Lock Brake System Warning Light Your vehicle has the Anti-Lock Brake System (ABS). This light will come on when your engine is started and may stay on for several seconds. This is normal. If the light stays on, turn the ignition to off. If the light comes on and the chime sounds when you are driving, pull your vehicle over to a safe location and stop as soon as possible. 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 222 earlier in this section. The ABS warning light will come on brieﬂy when you turn the ignition key to ON. This is normal. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. 223 StabiliTrak® Indicator Light This warning light should come on brieﬂy when the engine is started. If the warning light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak® system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly. This light will also ﬂash when the StabiliTrak® system is active. If the StabiliTrak® system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. See StabiliTrak® System on page 337 for more information. 224 Engine Coolant Temperature Warning Light The engine coolant temperature warning light will come on when the engine has overheated. If this happens you should pull over and turn off the engine as soon as possible. See Engine Overheating on page 410 for more information. Notice: Driving with the engine coolant temperature warning light on could cause your vehicle to overheat. See Engine Overheating on page 410. Your vehicle could be damaged, and it might not be covered by your warranty. Never drive with the engine coolant temperature warning light on. This light will also come on brieﬂy when starting your vehicle. If it does not, have your vehicle serviced. Engine Coolant Temperature Gage Tire Pressure Light This light comes on brieﬂy when you turn the ignition to ON. United States Canada This gage shows the engine coolant temperature. Under normal driving conditions the gage will read 210°F (100 °C) or less. If the gage pointer is near 260°F (125 °C), the engine is too hot. It means that your engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. See Engine Overheating on page 410 for more information. It will also come on when one or more of your tires are signiﬁcantly underinﬂated. A CHECK TIRE PRESSURE Driver Information Center (DIC) message will accompany the light. See DIC Warnings and Messages on page 244 for more information. Stop and check your tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Tires on page 435 for more information. This light will ﬂash for about 70 seconds and then stay on if a problem is detected with the Tire Pressure Monitor system. See Tire Pressure Monitor System on page 444 for more information. 225 If you keep driving your vehicle with Notice: this light on, after awhile, the emission controls might not work as well, your 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 your warranty. 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 can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 385. Malfunction Indicator Lamp Check Engine Light Your vehicle has 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 make sure 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 can prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. 226 This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: (cid:129) Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on your vehicle. Diagnosis and service might be required. (cid:129) Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service might be required. If the Light is Flashing The following can prevent more serious damage to your vehicle: (cid:129) Reduce vehicle speed. (cid:129) Avoid hard accelerations. (cid:129) Avoid steep uphill grades. If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible. 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 the vehicle. Turn the key 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/retailer for service as soon as possible. If the Light Is On Steady You might 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 390. 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. 227 (cid:129) Did you just drive through a deep puddle of water? If so, your 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. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 388. Poor fuel quality causes the engine not to run as efficiently as designed. You might 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 might 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/retailer can check the vehicle. Your dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed. 228 Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. 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. 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 the battery 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 you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your dealer/retailer can prepare the vehicle for inspection. 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. The light comes on when you turn your key to ON or START. It goes off once 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 This light ﬂashes when the security system is activated. This light tells you if there could be a problem with your engine oil pressure. For more information, see Theft-Deterrent Systems on page 118. 229 Fog Lamp Light Highbeam On Light The fog lamp light will come on when the fog lamps are in use. This light comes on when the high-beam headlamps are in use. The light will go out when the fog lamps are turned off. See Fog Lamps on page 186 for more information. Cruise Control Light This light comes on whenever you set the cruise control. See Headlamp High/Low-Beam Changer on page 176 for more information. Tow/Haul Mode Light This light comes on when the Tow/Haul mode has been activated. The light goes out when the cruise control is turned off. See Cruise Control on page 180 for more information. 230 For more information, see Tow/Haul Mode on page 133. Fuel Gage United States Canada When the ignition is on, the fuel gage tells you about how much fuel you have left in your tank. The gage will ﬁrst indicate empty before you are out of fuel, and you should get more fuel as soon as possible. When the fuel tank is low on fuel, the FUEL LEVEL LOW message will appear on the Driver Information Center (DIC). For more information see DIC Warnings and Messages on page 244. Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. (cid:129) At the gas station, the fuel pump shuts off before the gage reads full. It takes a little more or less fuel to ﬁll up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank.
