Temperature Display To adjust between Fahrenheit and Celsius: (cid:129) Press Y for approximately four seconds to toggle the display from F (Fahrenheit) to C (Celsius) to OFF. The temperature display will remain in its current state each time the ignition goes through its cycle. (cid:129) At start up, if the vehicle has been off for less than two and a half hours, and the last stored temperature was less than the current termperature, the sensor will increase 1°F every two minutes until the correct temperature is displayed. If the vehicle has been off more than two and a half hours, or the last stored temperature is greater than the current temperature, the current temperature immediately displays. If the temperature is 37°F (3°C) or lower, ICE will ﬂash on the temperature display. This display will ﬂash every two seconds for a period of one minute. If an abnormal temperature reading is displayed for an extended period of time, see your dealer/retailer. Under certain circumstances, a delay in updating the temperature is normal. Compass Display Press the Y button, located at the bottom of the mirror, next to the OnStar® control buttons to turn the compass/temperature display on or off. If CAL is not displayed, press and hold Y for 15 seconds, or until CAL is displayed. The compass is now in calibration mode. For more information, see “Compass Calibration” following. The mirror can be calibrated in one of two ways: (cid:129) Drive the vehicle in circles at less than 5 mph (8 km/h) until the CAL is no longer displayed in the compass window. Then continue to drive to make sure all eight directions are available. (cid:129) Drive the vehicle under normal operating conditions. 2-39 (cid:129) (cid:129) Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if the vehicle is outside of zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, the compass could give false readings. To adjust for compass variance: 1. Find your current location and variance zone number on the following zone map. 2-40 2. Press and hold Y for 12 seconds until a zone number appears in the display. The compass is now in zone mode. 3. Keep pressing the Y until the desired zone number appears in the display. Release the button. After approximately four seconds of inactivity, the new zone number will be locked in and the compass/temperature display will return. Cleaning the Mirror Use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that could cause the liquid cleaner to enter the mirror housing. Automatic Dimming Rearview Mirror with Compass and Temperature Display Your vehicle may have this mirror. When on, an automatic dimming mirror will dim to the proper level to minimize glare from lights behind you after dark. The mirror also includes a dual display in the upper right corner of the mirror with the compass reading and the outside temperature. Yb: Brieﬂy press this button to turn the display on or off. Your vehicle may also have a Rear Vision Camera. See Rear Vision Camera on page 2-44 for more information.

Automatic Dimming Mirror Operation O: Press this button to turn the automatic dimming feature on or off. The indicator light to the left of the button will turn on to indicate when the feature is on. Once the mirror is turned off, it will remain off until it is turned back on, or until the vehicle is restarted. Compass Operation Press the compass/temperature button once brieﬂy to turn the display on or off. 2-41 Compass Calibration The compass may need calibration if one of the following occurs: If CAL is displayed while driving in the vehicle. (cid:129) After approximately ﬁve seconds, the display does not show a compass heading, N for North, for example, there may be a strong magnetic ﬁeld interfering with the compass. Such interference may be caused by a magnetic antenna mount, magnetic note pad holder, or a similar magnetic item. The compass does not display the correct heading and the compass zone variance is set correctly. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push in the compass/temperature button for approximately nine seconds or until CAL is displayed. The compass can be calibrated by driving the vehicle in circles at 5 mph (8 km/h) or less until the display reads a direction. Compass Variance The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if the vehicle is outside zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. 2-42 Compass variance is the difference between earth’s magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings. To adjust for compass variance: 1. Find your current location and variance zone number on the following zone map. 2. Press and hold the compass/temperature button for six seconds until a zone number appears in the display. (cid:129) (cid:129) 3. Press the compass/temperature button on the bottom of the mirror until the new zone number appears in the display. After you stop pressing the button, the display will show a compass direction within a few seconds. Cleaning the Mirror Use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing. Outside Power Mirrors The outside power mirror controls are located on the driver’s door. To adjust the power mirrors, do the following: 1. Press the left side of the selector switch to choose the driver side mirror. Press the right side of the selector switch to choose the passenger side mirror. 2. Use the round, four-way control pad to move the mirror in the desired direction. If the mirror begins making a ratcheting sound, the mirror has reached the end of its travel and can go no farther in that direction. To stop the sound, reverse the mirror direction using the control pad. The mirrors can be manually folded inward to prevent damage when going through an automatic car wash or conﬁned space. Pull the mirror toward the vehicle to fold. To return the mirror to its original position, push outward. Be sure to return both mirrors to the unfolded position before driving. 2-43 Outside Convex Mirror Object Detection Systems {CAUTION: A convex mirror can make things (like other vehicles) look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on your right. Check your inside mirror or glance over your shoulder before changing lanes. The passenger side mirror is convex. A convex mirror’s surface is curved so more can be seen from the driver seat. It also makes things, like other vehicles, look farther away than they really are. Rear Vision Camera Your vehicle may be equipped with a rear vision camera system. Read this entire section before using the camera system. The rear vision camera system is designed to help the driver when backing up by displaying a view of the area behind the vehicle. When the driver shifts the vehicle into REVERSE (R), the video screen will automatically slide out from the rear view mirror. Once the driver shifts out of REVERSE (R), the video screen will slide back into the rear view mirror after a delay. The display has a guideline overlay that can help the driver align the vehicle when backing into a parking spot. To turn off the rear vision camera system, do the following: 1. Place the vehicle shift lever in PARK (P). 2. Turn the ignition key to the ACCESSORY position. 3. Press the right mirror button brieﬂy; the right green light indicator will turn off. The rear camera vision display is now disabled. 2-44 To turn on the rear camera vision feature again, press the right mirror button brieﬂy. The green light indicator will illuminate. The rear camera vision system is now enabled and the display will slide out from the mirror normally. To manually slide out the rear camera screen for cleaning, do the following: 1. Place the vehicle shift lever in PARK (P). 2. Turn the ignition key to the ACCESSORY or RUN position. 3. Press and hold the right mirror button for ﬁve seconds. The display will slide out from the mirror for 30 seconds; the right green LED indicator will remain illuminated. The camera screen will not be on when it slides out of the mirror. 4. If additional time is required for cleaning, repeat step 3. To resume normal operation, press the right button momentarily while the rear camera screen is out or wait 30 seconds for screen to slide back into the mirror. For more information on the automatic dimming, compass, and temperature features of the mirror, see Automatic Dimming Rearview Mirror with Compass and Temperature Display on page 2-41. {CAUTION: The Rear Vision Camera (RVC) system does not replace driver vision. RVC does not: (cid:129) Detect objects that are outside the camera’s ﬁeld of view, below the bumper, or underneath the vehicle. (cid:129) Detect children, pedestrians, bicyclists, or pets. Do not back the vehicle by only looking at the rear vision camera screen, or use the screen during longer, higher speed backing maneuvers or where there could be cross-traffic. Your judged distances using the screen will differ from actual distances. 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 RVC system, always check carefully before backing up by checking behind your vehicle. 2-45 Area Displayed On Screen The image is provided by the camera located on the rear bumper. The camera does not display objects which are close to either corner of the bumper or under the bumper. The spare tire and carrier extends rearward of the rear bumper. The area displayed on the screen may vary according to vehicle orientation or road conditions. Notice: The spare tire extends farther away from rear of the vehicle than the trailer hitch shown on rear vision camera display. Your spare tire could hit an object even though there appears to be enough distance on the display between the trailer hitch and objects behind you causing vehicle or property damage. Do not use this system to judge the distance between the spare tire and objects behind you. The following illustration shows the ﬁeld of view that the camera provides. The camera uses a special lens. The distance of the image that appears on the screen differs from the actual distance. The area displayed by the camera is limited. 2-46 When the System Does Not Seem To Work Properly The rear vision camera system may not work properly or display a clear image in the following situations: In the dark. (cid:129) When the sun or the beam of headlights is shining directly into the camera lens. If ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. If the back of the vehicle is in an accident, the position and mounting angle of the camera may change or the camera may be affected. Be sure to have the camera and its position and mounting angle checked at your dealer. (cid:129) Extreme high or low temperatures or extreme temperature changes can affect the image displayed. 2-47 (cid:129) (cid:129) (cid:129) For more information, visit onstar.com or onstar.ca, contact OnStar at 1-888-4-ONSTAR (1-888-466-7827) or TTY 1-877-248-2080, or press the OnStar button to speak with an OnStar advisor 24 hours a day, 7 days a week.

How OnStar Service Works In order to provide you with OnStar services, your vehicle’s OnStar system has the capability of recording and transmitting vehicle information. This information is automatically sent to an OnStar Call Center at the time of an OnStar button press, Emergency button press or if your airbags or AACN system deploys. The vehicle information usually includes your GPS location and, in the event of a crash, additional information regarding the accident that your vehicle has been involved in (e.g. the direction from which your vehicle was hit). When you use the Virtual Advisor feature of OnStar Hands-Free Calling, your vehicle also sends OnStar your GPS location so that we can provide you with location-based services. OnStar service cannot work unless your vehicle is in a place where OnStar has an agreement with a wireless service provider for service in that area. OnStar service also cannot work unless you are in a place where the wireless service provider OnStar has hired for that area has coverage, network capacity and reception when the service is needed, and technology that is compatible with the OnStar service. Not all services are available everywhere, particularly in remote or enclosed areas, or at all times. OnStar service that involves location information about your vehicle cannot work unless GPS satellite signals are unobstructed and available in that place as well. Your vehicle must have a working electrical system (including adequate battery power) for the OnStar equipment to operate. There are other problems OnStar cannot control that may prevent OnStar from providing OnStar service to you at any particular time or place. Some examples are damage to important parts of your vehicle in an accident, hills, tall buildings, tunnels, weather or wireless phone network congestion. 2-50 Your Responsibility You may need to increase the volume of your radio to hear the OnStar advisor. If the light next to the OnStar buttons is red, this means that your system is not functioning properly and should be checked by a dealer. If the light appears clear (no light is appearing), your OnStar subscription has expired. You can always press the blue OnStar button to conﬁrm that your OnStar equipment is active.

Because of the steps involved, it may be helpful to have another person available to assist you in the programming the Universal Home Remote. Keep the original hand-held transmitter for use in other vehicles as well as for future Universal Home Remote programming. It is also recommended that upon the sale of the vehicle, the programmed Universal Home Remote buttons should be erased for security purposes. See “Erasing Universal Home Remote Buttons” later in this section. When programming a garage door, park outside of the garage. Park directly in line with and facing the garage door opener motor-head or gate motor-head. Be sure that people and objects are clear of the garage door or gate you are programming. It is recommended that a new battery be installed in your hand-held transmitter for quicker and more accurate transmission of the radio-frequency signal. Universal Home Remote System Operation (With One Triangular LED) If there is one triangular Light Emitting Diode (LED) indicator light above the Universal Home Remote buttons, follow the instructions below. This system provides a way to replace up to three remote control transmitters used to activate devices such as garage door openers, security systems, and home automation devices. Do not use the Universal Home Remote with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982. 2-52 Programming the Universal Home Remote System If you have questions or need help programming the Universal Home Remote System, call 1-800-355-3515 or go to www.homelink.com. Programming a garage door opener involves time-sensitive actions, so read the entire procedure before you begin. If you do not follow these actions, the device will time out and you will have to repeat the procedure. To program up to three devices: 1. From inside the vehicle, press and hold down the two outside buttons at the same time, releasing only when the Universal Home Remote indicator light begins to ﬂash, after 20 seconds. This step will erase the factory settings or all previously programmed buttons. Do not hold down the buttons for longer than 30 seconds and do not repeat this step to program the remaining two Universal Home Remote buttons. 2. Hold the end of your hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from the Universal Home Remote buttons while keeping the indicator light in view. The hand-held transmitter was supplied by the manufacturer of your garage door opener receiver (motor head unit). 3. At the same time, press and hold both the Universal Home Remote button that you would like to use to control the garage door and the hand-held transmitter button. Do not release the Universal Home Remote button or the hand-held transmitter button until Step 4 has been completed. Some entry gates and garage door openers may require you to substitute Step 3 with the procedure noted in “Gate Operator and Canadian Programming” later in this section. 4. The indicator light on the Universal Home Remote will ﬂash slowly at ﬁrst and then rapidly after Universal Home Remote successfully receives the frequency signal from the hand-held transmitter. Release both buttons. 2-53 5. Press and hold the newly-trained Universal Home Remote button and observe the indicator light. If the indicator light stays on continuously, the programming is complete and your garage door should move when the Universal Home Remote button is pressed and released. You do not need to continue the programming Steps 6 through 8 and can stop here. If the Universal Home Remote indicator light blinks rapidly for two seconds and then turns to a constant light, continue with the programming Steps 6 through 8. It may be helpful to have another person available to assist with the remaining steps. 2-54 6. After Steps 1 through 5 have been completed, locate inside the garage the garage door opener receiver (motor-head unit). Locate the “Learn” or “Smart” button. The name and color of the button may vary by manufacturer. 7. Firmly press and release the “Learn” or “Smart” button. After you press this button, you will have 30 seconds to complete Step 8. 8. Immediately return to the vehicle. Firmly press and hold the Universal Home Remote button, chosen in Step 3 to control the garage door, for two seconds, and then release it. If the garage door does not move, press and hold the same button a second time for two seconds, and then release it. Again, if the door does not move, press and hold the same button a third time for two seconds, and then release. The Universal Home Remote should now activate the garage door. To program the remaining two Universal Home Remote buttons, begin with Step 2 of “Programming the Universal Home Remote System.” Do not repeat Step 1, as this will erase all previous programming from the Universal Home Remote buttons. Gate Operator and Canadian Programming If you have questions or need help programming the Universal Home Remote System, call 1-800-355-3515 or go to www.homelink.com. Canadian radio-frequency laws require transmitter signals to time out or quit after several seconds of transmission. This may not be long enough for Universal Home Remote to pick up the signal during programming. Similarly, some U.S. gate operators are manufactured to time out in the same manner. If you live in Canada, or you are having difficulty programming a gate operator or garage door opener by using the “Programming Universal Home Remote” procedures, regardless of where you live, replace Step 3 under “Programming Universal Home Remote” with the following: Continue to press and hold the Universal Home Remote button while you press and release every two seconds (cycle) the hand-held transmitter button until the frequency signal has been successfully accepted by the Universal Home Remote. The Universal Home Remote indicator light will ﬂash slowly at ﬁrst and then rapidly. Proceed with Step 4 under “Programming Universal Home Remote” to complete. 2-55 Using Universal Home Remote Press and hold the appropriate Universal Home Remote button for at least half of a second. The indicator light will come on while the signal is being transmitted. Erasing Universal Home Remote Buttons Erase the programmed buttons when you sell or terminate your lease. To erase all programmed buttons on the Universal Home Remote device: Reprogramming a Single Universal Home Remote Button To reprogram any of the three Universal Home Remote buttons, repeat the programming instructions earlier in this section, beginning with Step 2. For help or information on the Universal Home Remote System, call the customer assistance phone number under Customer Assistance Offices on page 7-5.

See Cruise Control on on page 3-10. page 3-11. 3-7 (cid:129) Turn and Lane-Change Signals The turn signal has one upward (for right) and one 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 automatically return to the off position. To signal a lane change, raise or lower the lever until the arrow starts to ﬂash. Hold it there until the change is completed. The lever will return by itself when released. An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. As you signal a turn or a lane change, if the arrows ﬂash more quickly than normal, a signal bulb may be burned out and other drivers will not see your vehicle’s 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 signaling a turn, check for a burned-out bulb or a blown fuse. For bulb replacement, see Taillamps, Turn Signal, Stoplamps and Back-up Lamps on page 5-50. For a blown fuse or circuit breaker, see Fuses and Circuit Breakers on page 5-102 Turn Signal On Chime If a turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each ﬂash of the turn signal and the message TURN SIGNAL will also appear in the DIC. To turn the chime and message off, move the turn signal lever to the off position. See “TURN SIGNAL” under DIC Warnings and Messages on page 3-43 DIC Warnings and Messages for more information. 3-8 Headlamp High/Low-Beam Changer 53(Headlamp High/Low Beam Changer): To change the headlamps from low to high beam, push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this indicator light on the instrument panel cluster will also be on. Flash-to-Pass This feature lets you use the high-beam headlamps to signal a driver in front of you that you want to pass. It works even if the headlamps are in the automatic position. To use it, pull the turn signal lever toward you, then release it. If your headlamps are in the automatic position or on low beam, your high-beam headlamps will turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster will come on. Release the lever to return to normal operation. 3-9 Windshield wipers work in all power modes, except when set to LOCK. After the engine is turned off, wipers will work in Retained Accessory Power (RAP) mode until a door is opened. See Retained Accessory Power (RAP) on page 2-20. Windshield Washer L (Washer Fluid): There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer ﬂuid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed. {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. Windshield Wipers You control the windshield wipers by turning the band with the wiper symbol on it. 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, if more wipes are needed. N (Delay): The wiper speed can be set for long or short delays between wipes. 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): For steady wiping at low speed, turn the band away from you to the ﬁrst solid position past the delay settings. 1 (High Speed): For high-speed wiping, turn the band to the second solid position past the delay settings. 9(Off): Move the band to off, to stop the wipers. Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. 3-10 Rear Window Wiper/Washer This knob is located on the instrument panel below the climate controls. 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). 9(Off): This position turns the system off. Z (Rear Wiper): Turn the knob to 1 for a slower wiping speed or to 2 for a faster wiping speed. 0 (Off): Turn the knob to 0 for off. =(Washer Fluid): To wash and wipe the window, press the button within the knob with this symbol. The rear window washer uses the same ﬂuid bottle as the windshield washer. However, the rear window washer will run out of ﬂuid before the windshield washer. If the windshield can be washed, but not the rear windows, check the ﬂuid level. R (On): This position activates the system. + (Resume/Accelerate): Move the lever to this symbol to make the vehicle accelerate or resume to a previously set speed. rT (Set): Press this button to set the speed. 3-11 Cruise control will not work if your parking brake is set, or if the master cylinder brake ﬂuid level is low. If you apply your brakes, the cruise control shuts off. Setting Cruise Control {CAUTION: {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. The cruise control disengages, if the vehicle has the Traction Control System (TCS) and it begins to limit wheel spin. See Traction Control System (TCS) on page 4-5. When road conditions allow you to safely use it again, you can turn cruise control back on. 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. Move the cruise control switch to on. 2. Get up to the speed desired. 3. Press in the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal. The cruise symbol on the instrument panel comes on when the cruise control is engaged. 3-12 Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake or step on the clutch. This, of course, disengages the cruise control. But you do not need to reset it. Once you are going about 25 mph (40 km/h) or more, you can move the cruise control switch brieﬂy from on to resume/accelerate. The vehicle will go back to the chosen speed and stays there. If you hold the switch at resume/accelerate the vehicle will keep going faster until you release the switch or apply the brake. Do not hold the switch at resume/ accelerate, unless you want the vehicle to go faster. Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: (cid:129) Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You will now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off. (cid:129) Move the cruise switch from on to resume/ accelerate. Hold it there until you get up to the speed you want, and then release the switch. To increase your speed in very small amounts, move the switch brieﬂy to resume/accelerate. Each time you do this, your vehicle goes about 1 mph (1.6 km/h) faster. 3-13 Reducing Speed While Using Cruise Control (cid:129) Press and hold the set button until you reach the desired lower speed, then release it. To slow down in very small amounts, brieﬂy press the set button. Each time you do this, you will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle slows down to the cruise control speed you set earlier. Using Cruise Control on Hills How well your cruise control works on hills depends upon your speed, load, and the steepness of the hills. When going up steep hills, you might want 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 To turn off the cruise control, do one of the following: (cid:129) Step lightly on the brake pedal. (cid:129) Move the cruise control switch to off. Lightly tap or press the clutch, if you have a manual transmission. Erasing Speed Memory When you turn off the cruise control or the ignition, the cruise control set speed memory is erased. 3-14 (cid:129) (cid:129) Exterior Lamps The control on the driver’s side of your instrument panel operates the exterior lamps. O (Exterior Lamps): Turn the knob, located to the right of this symbol, to choose one of the four exterior lamp positions. O (Off): Turn the knob to this position to turn off all exterior lamps, including the Daytime Running Lamps (DRL). This is a momentary control that springs back to AUTO when released. Vehicles ﬁrst sold in Canada do not have the DRL disable feature available. Vehicles ﬁrst sold in Canada cannot turn off the DRL unless the following conditions are met: The vehicle has an automatic transmission. The gear position is in PARK (P). The headlamp switch is turned to the Off position. AUTO (Automatic): Turn the knob to this position to automatically turn on the headlamps at normal brightness, together with the following: (cid:129) Sidemarker Lamps Taillamps (cid:129) Parking Lamps Instrument Panel Lights Due to the momentary switch design, the automatic headlamps may be disabled even if the control is in the AUTO position. To enable automatic lighting, do any of the following: Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. Turn the headlamp control from the parking lamp or headlamp position to AUTO. 3-15 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) To disable automatic lighting, do any of the following: Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. Turn the headlamp control from AUTO to the parking lamp or headlamp position. See Automatic Headlamp System on page 3-17 for more information. Vehicles ﬁrst sold in Canada with an automatic transmission cannot turn off automatic headlamps unless the gear position is in PARK (P) and the headlamp switch is turned to the Off position. Vehicles ﬁrst sold in Canada with a manual transmission can turn off the automatic headlamps with the headlamp control; however, the parking lamps will remain on. ;(Parking Lamps): Turn the knob to this position to turn on the parking lamps, together with the following: (cid:129) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights 2(Headlamps): Turn the knob to this position to turn on the headlamps, together with the previously listed lamps and lights. The headlamps can be switched from low to high beam by pushing the turn signal/multifunction lever toward the instrument panel. Headlamps on Reminder A headlamp reminder chime will sound if the following conditions are met: The driver door is open. (cid:129) Parking lamps or headlamps are manually turned on. The key is either not in the ignition switch, or it is in the LOCK position of the ignition switch. The headlamp reminder cannot be turned off if the conditions listed above are met. In the automatic mode, the headlamps turn off once the ignition is in ACC. 3-16 (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) 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 come on when the following conditions are met: The ignition is on. The exterior lamps control is in AUTO. The transmission is not in PARK (P) if you have an automatic transmission. The light sensor determines it is daytime. When the DRL are on, no other lamps are on. The instrument panel will not be lit up either. For vehicles ﬁrst sold in Canada, if parking lamps are manually turned on, DRL will stay on. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps. As with any vehicle, you should turn on the regular headlamp system when you need it. To turn off the DRL, see Exterior Lamps on page 3-15. Vehicles ﬁrst sold in Canada cannot turn off DRL unless certain conditions are met. See Exterior Lamps on page 3-15. Automatic Headlamp System When it is dark enough outside, the automatic headlamp system will turn on after the transmission has been shifted from PARK (P) to DRIVE (D). The headlamps, taillamps, sidemarker, parking lamps, roof marker lamps, and the instrument panel lights will turn on at normal brightness. The radio lights will become more dim when the headlights are off compared to when the headlights are on. Your vehicle has a light sensor located on the top of the instrument panel. Be sure it is not covered, or the system will be on whenever the ignition is on. The system may also turn on the headlamps when driving through a parking garage, heavy overcast weather, or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp system so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor detects a change in lighting lasting longer than the delay. 3-17 (cid:129) (cid:129) (cid:129) (cid:129) 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, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 3-19. Off-Road Lamps The off-road lamps, if the vehicle has them, provide auxiliary lighting when the vehicle is used off road. These lamps are not intended to be used in place of existing vehicle lighting. The lamps are not to be used on any public street or highway and are to be covered when not in use. Check your state and local laws before installing or using any auxiliary lighting. In some states it may be necessary to remove the roof lamps when operating the vehicle on the highway. 3-18 Roof Mounted Off-Road Light Switch Lower Grille Off-Road Light Switch The switches for the off-road lamps are located in the center of the instrument panel below the climate controls. One switch is used for the front lower-grille mounted off-road lamps, if the vehicle has them, and the other switch is used for the roof-mounted off-road lamps, if the vehicle has them. To use the lamps, remove the covers from the lamps and press the switch to turn them on or off. An indicator light on the switch will turn on when the lamps are on. Notice: Turning on the off-road lamps before removing the lamp covers could damage the off-road lamps and the covers. Always remove the covers before turning on the off-road lamps. The off-road lamps remain on even after the ignition is turned off. The off-road lamp switch must be pressed to turn them off. Fog Lamps Your vehicle has fog lamps. You can use them for better vision in foggy or misty conditions. Your parking lamps and/or low-beam headlamps must be on for your fog lamps to work. The fog lamp button is located in the exterior lamps control. Press the button to turn the fog lamps on while the headlamps or parking lamps are on. Press the button again to turn them off. An indicator light will glow in the button when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use your fog lamps in the dark without turning on the headlamps. The fog lamps will go off whenever your high-beam headlamps come on. When the high beams go off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The thumbwheel for this feature is located next to the exterior lamp control. Turn the thumbwheel up or down to brighten or dim the instrument panel lights and the radio display. The instrument panel lights, cluster, and radio display do not dim to complete darkness. Turn the thumbwheel all the way up to turn the dome lamps on. Dome Lamp The dome and footwell lamps come on when any door is opened. The dome lamps are located in the cargo and front area of the vehicle. The dome and footwell lamps can be turned on by turning the thumbwheel, located next to the exterior lamps control, all the way up. In this position, the lamps remain on whether a door is opened or closed. 3-19 Dome Lamp Override E (Dome Lamp Override): You can use the dome override button, located below the exterior lamps control, to set the dome and footwell lamps to come on automatically when a door is opened, or to remain off. To turn the lamps off, press the button into the in position. With the button in this position, the dome lamps will remain off when the doors are open. To return the lamps to automatic operation, press the button again and return it to the out position. With the button in this position, the dome lamps will come on when you open a door. Exit Lighting With exit lighting, the interior lamps will come on when you remove the key from the ignition. The lamps will not come on if the dome override button is pressed in. Reading Lamps Your vehicle has reading lamps. Press the button located next to the lamp to turn them on or off. These lamps will not come on with the dome lamps. 3-20 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, you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following 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. Battery Run-Down Protection This feature shuts off the dome lamp if it is left on for more than 20 minutes when the ignition is in LOCK. This will help prevent your battery from running down. Accessory Power Outlet(s) Your vehicle has accessory power outlets. With accessory power outlets you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. Your vehicle has two accessory power outlets located on the lower part of the instrument panel below the climate control system and there may be one located in the rear cargo area. A small cap must be pulled down to access an accessory power outlet. When not using an outlet, be sure to cover it with the protective cap. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage rating of 20 amperes. Certain electrical accessories may not be compatible with 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 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 of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. 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 3-21 If you put papers, pins, or other ﬂammable Ashtray(s) and Cigarette Lighter Your vehicle may have an ashtray and cigarette lighter. Your ashtray is located in your center console area. The ashtray can be removed for cleaning. When the ashtray is removed, this area can also be used as a cupholder. Notice: 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. To use the lighter, press it in all the way, and let go. When it’s ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating does not let the lighter back away from the heating element when it is hot. Damage from overheating can occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. 3-22 Climate Controls Climate Control System The heating, cooling, and ventilation of the vehicle can be controlled with this system. Temperature: Turn the left knob on the control panel to adjust the temperature of the air in the vehicle. Turn the knob clockwise or counterclockwise to increase or decrease the temperature. #(Air Conditioning): Press the center of the left knob on the control panel to turn the air conditioning system on or off. An indicator light on the button will be lit when the air conditioning is turned on. This system cools and dehumidiﬁes the air entering the vehicle. The air conditioning will not function if the fan is turned off. If air conditioning is selected with fan off, the indicator light ﬂashes three times and then turns off. this button to turn the recirculation mode on or off. An indicator light on the button comes on to show that the recirculation mode is activated. A slight change in engine performance may occur when the air conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature. The air conditioning system removes moisture from the air, so sometimes there may be a small amount of water dripping underneath the vehicle while idling or after turning off the engine. This is normal. 9(Fan): Turn the center knob on the control panel to control the fan speed. Turn the knob clockwise or counterclockwise to increase or decrease the fan speed. 9(Off): Turn the center knob to this position to turn the fan off. With the fan off, you may still experience airﬂow from the system that increases with vehicle speed depending on the mode and temperature settings. Enable recirculation mode to stop this airﬂow from occurring. @ (Recirculation): Press the center of the fan control knob to recirculate air inside the vehicle and prevent outside air from coming in. It can be used to prevent outside odors from entering the vehicle and cool the air inside the vehicle more quickly. Press Recirculation is available in the bi-level, and vent modes. Recirculation is not available while in ﬂoor, ﬂoor/defog and defrost mode. If recirculation is selected in these modes, the indicator ﬂashes three times indicating it is not available in that mode. When the recirculation mode is turned on, the air conditioning turns on automatically. When it is hot enough outside, the recirculation mode may turn on automatically to help improve cooling performance. The indicator light will be lit to show this mode is active. If the recirculation button is pressed while in this mode, the light will ﬂash three times and stay on to indicate that recirculation may not be shut off. The right knob on the control panel is used to direct the airﬂow inside the vehicle. In-between modes are available by moving the right control knob between modes with symbols. The in-between mode is a combination of the two modes that the control is centered between. Turn the right knob to select one of the following modes: H (Vent): This mode directs air to the instrument panel outlets. 3-23 \(Bi-Level): This mode directs air to the instrument panel outlets, and the remaining air to the ﬂoor outlets and the defroster and side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. [(Floor): This mode directs air to the ﬂoor outlets, side window outlets, and defroster. Recirculation is not available in this mode. 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 or frost from the windshield and side windows. 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. For best results, clear all snow and ice from the windshield before defrosting. /(Floor/Defog): This mode directs the air to the windshield, the side window outlets, and to the ﬂoor outlets. When this mode is selected, the system runs the air conditioning system unless the outside temperature is near freezing or below. Recirculation is not available in this mode. 3-24 0(Defrost): This mode directs most of the air to the windshield, and the side window outlets. When this mode is selected, the system runs the air conditioning system unless the outside temperature is near or below freezing. Recirculation is not available in this mode. Do not drive the vehicle until all the windows are clear. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window when the key is in the ignition and turned to ON/RUN. =(Rear Defogger): Press the center of the right knob on the control panel to turn the rear window defogger on or off. First press of this button activates the rear window defogger for 15 minutes and each subsequent activation lasts seven and one-half minutes. 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. Outlet Adjustment Use the air outlets located in the center and on the side of your instrument panel to direct the airﬂow. Your vehicle has air outlets that allow you to adjust the direction and amount of airﬂow inside the vehicle. Move the louvers up or down to change the direction of the airﬂow. Use the thumbwheel under the outlets to change the direction of the airﬂow from left to right. Operation Tips (cid:129) Enable recirculation mode for maximum air conditioning performance. (cid:129) Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the ﬂow of air into your vehicle. (cid:129) Use of non-GM approved hood deﬂectors may adversely affect the performance of the system. (cid:129) Keep the path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. 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. 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. Your vehicle may also have a Driver Information Center (DIC) that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-40 for more information. 3-25 Instrument Panel Cluster Your 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, about how much fuel you have used, and many other things you will need to know to drive safely and economically. United States 3.7L L5 Automatic Transmission version shown, 5.3L V8, Canada and Manual Transmission similar 3-26 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 (used in the United States) or kilometers (used in Canada). The odometer mileage can be checked without the vehicle running by pressing the trip information stem. See “Odometer” under DIC Operation and Displays on page 3-40 for more information. If the cluster is replaced the new one will automatically detect and update the vehicle’s accumulated mileage. Trip Odometer Your vehicle has a trip odometer that can tell you how far your vehicle has been driven since you last set the trip odometer to zero. See “Trip Odometer” under DIC Operation and Displays on page 3-40 for more information. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). 3.7L L5 Shown, 5.3L V8 Similar If you operate the engine with the Notice: tachometer in the shaded warning area, your vehicle could be damaged, and the damages would not be covered by your warranty. Do not operate the engine with the tachometer in the shaded warning area. 3-27 Safety Belt Reminders Safety Belt Reminder Light When the engine is started, 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. Passenger Safety Belt Reminder Light Several seconds after the engine is started, 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 1-62 for more information. The passenger safety belt light, located on the instrument panel, will come on and stay on for several seconds and then ﬂash for several more. This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. 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. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. 3-28 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 1-54. This light will come on when you start your vehicle, and it will ﬂash for a few seconds. The light should go out and the system is ready. 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. {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 start the engine. If the light does not come on then, have it ﬁxed immediately. If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message may also come on. See DIC Warnings and Messages on page 3-43 for more information. 3-29 {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. Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your instrument panel has a passenger airbag status indicator. United States Canada When you start the vehicle, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol to let you know the status of the right front passenger’s frontal airbag. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inﬂate). 3-30 {CAUTION: Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off. If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. See Passenger Sensing System on page 1-62 for more on this, including important safety information. If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer/retailer for service. {CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the airbag(s). See Airbag Readiness Light on page 3-29 for more on this, including important safety information. 3-31 Charging System Light Up-Shift Light This 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. Your vehicle may have an up-shift light. 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. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-43 for more information. This light could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. 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. When this light comes on, you should shift to the next higher gear if weather, road, and traffic conditions allow you to. See Manual Transmission Operation on page 2-26 for more information. 3-32 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 could be 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. When the ignition is on, the brake system warning light will also come on when you set your parking brake. See Parking Brake on page 2-32 for more information. 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 4-48. {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. 3-33 Antilock Brake System Warning Light Traction Off Light For vehicles with the Antilock Brake System (ABS), this light will come on brieﬂy when you start the engine. That 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. If the ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light 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 antilock brakes. If the regular brake system warning light is also on, you do not have antilock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 3-33 For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-43 for all brake related DIC messages. 3-34 If you have the Traction Control System (TCS), this light will come on when the TCS has been turned off. This light will come on brieﬂy when the ignition is turned to ON, if it does not the system may require service. For more information on the traction off light, see Traction Control System (TCS) on page 4-5. StabiliTrak® Not Ready Light If you have the StabiliTrak® system, this light will come on when the StabiliTrak® system has been turned off. This light will come on brieﬂy when the ignition is turned to ON, if it does not the system may require service. For more information, see StabiliTrak® System on page 4-7. Engine Coolant Temperature Gage Tire Pressure Light This light comes on brieﬂy when the engine is started. United States Canada This gage shows the engine coolant temperature. If the gage pointer is in the shaded area of the gage, 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 5-29 for more information. This light will also come on when one or more of your tires are signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), may accompany the light. See DIC Warnings and Messages on page 3-43 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 5-54 for more information. If a problem is detected with the Tire Pressure Monitor System, this light will ﬂash for approximately 60 seconds and then stay on solid for the remainder of the ignition cycle. See Tire Pressure Monitor System on page 5-63 for more information. 3-35 Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It makes sure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The check engine light comes on to indicate that there is an OBD II problem and service is required. Malfunctions often are 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. Notice: If you keep driving your vehicle with this light on, after a while, 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. 3-36 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 5-3. This light comes on, as a check to show it is working, when the ignition is turned ON/RUN but the engine is not running. If the light does not come on, have it repaired. This light also comes on during a malfunction in one of two ways: Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on your vehicle. Diagnosis and service might be required. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service might be required.
