lever is in PARK (P) with the shift lever button fully released, and (cid:129) Prevent movement of the shift lever out of PARK (P), unless the ignition is in ON/RUN or ACC/ ACCESSORY and the regular brake pedal is applied. 2-34 Parking Over Things That Burn Engine Exhaust {CAUTION: {CAUTION: Things that can burn could touch hot exhaust parts under your vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn. Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you cannot see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: (cid:129) The exhaust system sounds strange or different. (cid:129) Your vehicle gets rusty underneath. (cid:129) Your vehicle was damaged in a collision. (cid:129) Your vehicle was damaged when driving over high points on the road or over road debris. (cid:129) Repairs were not done correctly. (cid:129) Your vehicle or the exhaust system has been modiﬁed improperly. If you ever suspect exhaust is coming into your vehicle: (cid:129) Drive it only with all the windows down to blow out any CO; and (cid:129) Have your vehicle ﬁxed immediately. 2-35 Running the Engine While Parked It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: {CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier caution under Engine Exhaust on page 2-35. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control fan is at the highest setting. One place this can happen is a garage. Exhaust — with CO — can come in easily. NEVER park in a garage with the engine running. Another closed-in place can be a blizzard. See Winter Driving on page 4-28. It can be dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake ﬁrmly set. Your vehicle can roll. Do not leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to PARK (P). Follow the proper steps to be sure your vehicle will not move. See Shifting Into PARK (P) on page 2-33. If you are pulling a trailer, see Towing a Trailer on page 4-41. 2-36 Mirrors Automatic Dimming Rearview Mirror with OnStar®, Compass and Temperature Display Your vehicle may have this feature. When on, an automatic dimming inside rearview mirror automatically dims 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 face. The compass reading and the outside temperature will both appear in the display at the same time. P(On/Off): This is the on/off button. Temperature and Compass Display Press the on/off button, located to the far left, brieﬂy to turn the compass/temperature display on or off. If the display reads CAL, you will need to calibrate the compass. For more information on calibration see “Compass Calibration” following. To adjust between Fahrenheit and Celsius: 1. Press and hold the on/off button for approximately four seconds until either a ﬂashing F or C appears. 2. Press the button again to change the display to the desired unit of measurement. After approximately four seconds of inactivity, the new unit will be locked in and the compass/temperature display will return. If an abnormal temperature reading is displayed for an extended period of time, please see your dealer. Under certain circumstances, a delay in updating the temperature is normal. Automatic Dimming Mirror Operation The automatic dimming mirror function is turned on automatically each time the ignition is started. To operate the automatic dimming mirror, do the following: 1. Make sure the green indicator light, located to the left of the on/off button, is lit. If it’s not, press and hold the on/off button for approximately six seconds until the green light comes on, indicating that the mirror is in automatic dimming mode. 2. Turn off the automatic dimming mirror function by pressing and holding the on/off button for approximately six seconds, until the green indicator light turns off. 2-37 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 you live 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, your compass could give false readings. To adjust for compass variance do the following: 1. Find your current location and variance zone number on the following zone map. 2-38 2. Press and hold the on/off button until a Z and a zone number appears in the display. The compass is now in zone mode. 3. Keep pressing the on/off button 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. 4. Calibrate the compass as described below. Compass Calibration The compass may need calibration if one of the following occurs: (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 the on/off button for approximately 12 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. Cleaning the Mirror When 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.

Press this button to warm the driver’s and passenger’s outside rearview mirrors to help clear them of ice, snow, and condensation. See “Rear Window Defogger” under Dual Automatic Climate Control System on page 3-26 for more information. 2-42 Object Detection Systems Ultrasonic Rear Parking Assist (URPA) If your vehicle has the Ultrasonic Rear Parking Assist (URPA) system, it helps you park easier and avoid other vehicles while in REVERSE (R). It operates at speeds less than 5 mph (8 km/h). It can determine how close objects are to the rear bumper, up to 8 feet (2.5 m) behind your vehicle. The distance sensors are located on the rear bumper. {CAUTION: The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect: (cid:129) objects that are below the bumper, underneath the vehicle, or if they are too close or far from the vehicle (cid:129) children, pedestrians, bicyclists, or pets. CAUTION: (Continued) CAUTION: (Continued) If you do not use proper care before and while backing; vehicle damage, injury, or death could occur. Even with URPA, always check behind your vehicle before backing up. While backing, be sure to look for objects and check your vehicle’s mirrors. On some vehicles this display is located near the passenger side rear window and can be seen by looking over your right shoulder. If your vehicle has the display, there are three color-coded lights to provide distance and system information. If your vehicle does not have the display and it has URPA, you will hear the beeps as described in the following information. 2-43 How the System Works URPA comes on automatically when the shift lever is moved into REVERSE (R). The rear display will then brieﬂy illuminate to let you know the system is working. URPA operates only at speeds less than 5 mph (8 km/h). If you are above this speed, the red light on the rear display will ﬂash. To be detected, objects must be at least 10 inches (25.4 cm) off the ground and below tailgate level. Objects must also be within 8 feet (2.5 m) from your rear bumper. This distance may be less during warmer or humid weather. A single beep will sound the ﬁrst time an object is detected between 20 inches (0.5 m) and 8 feet (2.5 m) away. Beeping will occur for three seconds when you are closer than 1 foot (0.3 m) from the object. The following describes what will occur with the URPA display as you get closer to a detected object: Description amber light amber/amber lights amber/amber/red lights amber/amber/red lights ﬂashing and beep for three seconds English 8 ft 40 in 23 in 1 ft Metric 2.5 m 1.0 m 0.6 m 0.3 m The system can be disabled by pressing the rear park aid disable button located next to the radio. The indicator light will come on to indicate that URPA is off. If you use URPA while the tailgate is Notice: lowered, it may not detect an object behind your vehicle, and you might back into the object and damage your vehicle. Always verify the tailgate is closed when using URPA or turn off URPA when driving with the tailgate lowered. 2-44 When the System Does Not Seem to Work Properly The driver disables the system. The parking brake pedal is depressed. The ultrasonic sensors are not clean. Keep your vehicle’s rear bumper free of mud, dirt, snow, ice and slush. For cleaning instructions, see Washing Your Vehicle on page 5-102. (cid:129) A trailer was attached to your vehicle, or a bicycle or an object was hanging out of your tailgate during your last drive cycle, the red light may illuminate in the rear display. Once the attached object is removed, URPA will return to normal operation. (cid:129) A tow bar is attached to your vehicle. The vehicle’s bumper is damaged. Take the vehicle to your dealer/retailer to repair the system. (cid:129) Other conditions may affect system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck. If the system is still disabled, after driving forward at least 15 mph (25 km/h), take your vehicle to your dealer/retailer.

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. Location information about your vehicle is only available if the GPS satellite signals are unobstructed and available. 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. Your Responsibility Increase the radio volume if you cannot 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 your dealer/retailer. If the light appears clear (no light is appearing), your OnStar subscription has expired. You can always press the OnStar button to conﬁrm that your OnStar equipment is active. 2-48 Universal Home Remote System Universal Home Remote System Operation (With Three Round LED) Universal Home Remote System The Universal Home Remote System provides a way to replace up to three hand-held Radio-Frequency (RF) transmitters used to activate devices such as garage door openers, security systems, and home lighting.

Most garage door openers sold before 1996 are Fixed Code units. 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. 1. To verify if you have a Fixed Code garage door opener, remove the battery cover on your hand held transmitter supplied by the manufacturer of your garage door opener motor. If you see a row of dip switches similar to the graphic above, you have a Fixed Code garage door opener. If you do not see a row of dip switches, return to the previous section for Programming Universal Home Remote – Rolling Code. Your hand held transmitter may have between eight to 12 dip switches depending on the brand of transmitter. 2-52 Your garage door opener receiver (motor head unit) may also have a row of dip switches that can be used when programming the Universal Home Remote. If the total number of switches on the motor head and hand held transmitter are different, or if the dip switch settings are different, use the dip switch settings on the motor head unit to program your Universal Home Remote. The motor head dip switch settings can also be used when you do not have the original hand held transmitter. Example of Eight Dip Switches with Two Positions Example of Eight Dip Switches with Three Positions Your panel of switches may not appear exactly as they do in the examples, but they should be similar. The switch positions on your hand-held transmitter may be labeled as follows: (cid:129) A switch in the up position may be labeled as “Up,” “+,” or “On.” (cid:129) A switch in the down position may be labeled as “Down,” “−,” or “Off.” (cid:129) A switch in the middle position may be labeled as “Middle,” “0,” or “Neutral.” 2-53 2. Write down the eight to 12 switch settings from left to right as follows: (cid:129) When a switch is in the up position, write “Left.” (cid:129) When a switch is in the down position, write “Right.” If a switch is set between the up and down position, write “Middle.” The switch settings that you wrote down in Step 2 will now become the button strokes you enter into the Universal Home Remote in Step 4. Be sure to enter the switch settings that you wrote down in Step 2, in order from left to right, into the Universal Home Remote, when completing Step 4. 3. From inside your vehicle, ﬁrst ﬁrmly press all three buttons at the same time for about three seconds. Release the buttons to put the Universal Home Remote into programming mode. 4.

The hazard warning ﬂasher button is located on top of the steering column. 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. The hazard warning ﬂashers work no matter what ignition position the key is in, and even if the key is not in the ignition. When the hazard warning ﬂashers are on, your vehicle’s turn signals will not work. 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 To sound the horn, press the horn symbols located on the steering wheel. Tilt Wheel The tilt wheel lets you adjust the steering wheel before you drive. Raise it to the highest level to give your legs more room when exiting or entering the vehicle. 3-6 The tilt steering wheel lever is located on the lower left side of the steering column. To tilt the wheel, hold the steering wheel and pull the lever. Then move the steering wheel to a comfortable position and release the lever to lock the wheel in place. Turn Signal/Multifunction Lever The lever on the left side of the steering column includes the following: (cid:129) GTurn and Lane Change Signals. See Turn and Lane-Change Signals on page 3-8. (cid:129) 53Headlamp High/Low-Beam Changer. See Headlamp High/Low-Beam Changer on page 3-8. Flash-to-Pass. See Flash-to-Pass on page 3-9. (cid:129) NWindshield Wipers. See Windshield Wipers on page 3-9. (cid:129) LWindshield Washer. See Windshield Washer on page 3-10. For information on the exterior lamps, see Exterior Lamps on page 3-14. 3-7 (cid:129) Turn Signal On Chime If your turn signal is left on for more than 3/4 of a mile (1.2 km), a chime sounds at each ﬂash of the turn signal and the message TURN SIGNAL ON also appears in the Driver Information Center (DIC). Move the turn signal lever to the off position, to turn the chime and message off. Headlamp High/Low-Beam Changer 53(Headlamp High/Low Beam Changer): Push the lever toward the instrument panel, to change the headlamps from low to high beam. Pull the multifunction lever toward you and release it, to return to low-beam headlamps. When the high beams are on, this indicator light on the instrument panel cluster will also be on. Turn and Lane-Change Signals The turn signal has two upward (for right) and two downward (for left) positions. Each position signals 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 returns automatically to the starting position. To signal a lane change, raise or lower the lever until the arrow starts to ﬂash. Hold it there until your lane change is completed. The lever returns to the starting position by itself when it is released. An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. If the arrows ﬂash more quickly than normal as you signal a turn or a lane change, a signal bulb might be burned out and other drivers will not see the turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not come on when you signal a turn, check for burned-out bulbs and a blown fuse. See Fuses and Circuit Breakers on page 5-108. 3-8 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 the headlamps are in the automatic position or on low beam, your high-beam headlamps turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster comes on. Release the lever to return to normal operation. Windshield Wipers 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 5-57. 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. Turn the band with the wiper symbol to control the windshield wipers. 8(Mist): Turn the band to mist for a single wiping cycle. Hold it there until the wipers start. Then let go. The wipers 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): Turn the band to adjust the delay time. The delay between wiping cycles becomes shorter as the band is moved to the top of the lever. This can be very useful in light rain or snow. 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. 3-9 Windshield 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. L(Washer Fluid): Push the paddle marked with the windshield washer symbol at the top of the multifunction lever, to spray washer ﬂuid on the windshield. The wipers clear the window and then either stop or return to the preset speed. 3-10 Heated Windshield Washer For vehicles with the heated windshield washer ﬂuid system it can be used to help clear ice, snow, tree sap, or bugs from your windshield. The button is located in the switchbank under the climate controls. Push the heated washer ﬂuid button to activate the heated windshield washer ﬂuid system. The indicator light will ﬂash. This activation initiates four heated wash/wipe cycles. The ﬁrst heated wash/wipe cycle may take up to 40 seconds to occur, depending on outside temperature. After the ﬁrst wash/wipe cycle, it may take up to 20 seconds for each of the remaining cycles to begin. 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 may ﬂow out of the washer nozzles for a short period of time before washer ﬂuid is sprayed. This is a normal condition. When you apply your brakes, cruise control is turned off. If your vehicle has the StabiliTrak® system and begins to limit wheel spin while you are using cruise control, the cruise control will automatically disengage. See StabiliTrak® System on page 4-5. When road conditions allow you to safely use it again, you may turn the cruise control back on. Cruise Control {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. 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). 3-11 The cruise control buttons are located on left side of the steering wheel. Setting Cruise Control Cruise control will not work if the parking brake is set, or if the master cylinder brake ﬂuid level is low. The cruise control light on the instrument panel cluster will come 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 desired speed. 3. Press the SET− button located on the steering wheel and release it. 4. Take your foot off the accelerator. T (On/Off): This button can both activate and turn off the system. The indicator light is on when cruise control is on and turns off when cruise control is off. + RES (Resume/Accelerate): Press this button to make the vehicle accelerate or resume to a previously set speed. SET − (Set/Coast): Press this button to set the speed or make the vehicle decelerate. [ (Cancel): Press this button to cancel cruise control without erasing the set speed from memory. 3-12 Resuming a Set Speed If you apply the brakes while the cruise control is set, the cruise control is disengaged. But it does not need to be reset. Once the vehicle speed reaches about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle will go back to the previous set 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 your new desired speed, then release it. To increase vehicle speed in small increments, press the +RES button. Each time this is done, the vehicle will go about 1 mph (1.6 km/h) faster. Reducing Speed While Using Cruise Control To reduce the vehicle speed while using cruise control: (cid:129) Press and hold the SET– button on the steering wheel until the desired lower speed is reached, then release it. 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 the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previous set cruise speed. 3-13 (cid:129) (cid:129) Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle speed, load, and the steepness of the hills. While going up steep hills, you might have to step on the accelerator pedal to maintain the vehicle’s speed. While going downhill, you might have to brake or shift to a lower gear to keep the vehicle’s 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 wheel. (cid:129) Press the On/Off button on the steering wheel. Erasing Speed Memory When the cruise control or the ignition is turned off, the cruise control set speed memory is erased. 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 Taillamps (cid:129) Parking Lamps License Plate Lamps Instrument Panel Lights The exterior lamps control has four positions: O(Off): Turn the control to this position to turn off the automatic headlamps and daytime running lamps (DRL). Turn the headlamp control to the off position again to turn the automatic headlamps or DRL back on. For vehicles ﬁrst sold in Canada, the off position will only work when the vehicle is shifted into PARK (P). 3-14 (cid:129) (cid:129) (cid:129) When the headlamps are turned on while the vehicle is on, the headlamps turn off automatically 10 minutes after the ignition is turned off. When the headlamps are turned on while the vehicle is off, the headlamps will stay on for 10 minutes before automatically turning off to prevent the battery from being drained. Turn the headlamp control to off and then back to the headlamp on position to make the headlamps stay on for an additional 10 minutes. Push the turn signal/multifunction lever toward the instrument panel to change the headlamps from low beam to high beam. Headlamps on Reminder A reminder chime will sound when the headlamps or parking lamps are manually turned on and the ignition is off, in LOCK, ACCESSORY, or a door is open. Turn the light off, then back on, to stop the chime. 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 Instrument Panel Lights Taillamps License Plate Lamps When the vehicle is turned off and the headlamps are in AUTO, the headlamps may automatically remain on for a set time. The time of the delay can be changed using the DIC. See Driver Information Center (DIC) on page 3-52. ;(Parking Lamps): Turn the control to this position to turn on the parking lamps together with the following: Instrument Panel Lights Taillamps License Plate Lamps 2(Headlamps): Turn the control to this position to turn on the headlamps together with the following: (cid:129) Parking Lamps Instrument Panel Lights Taillamps License Plate Lamps 3-15 (cid:129) (cid:129) (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). The light sensor determines it is daytime. When the DRL are on, only the DRL lamps will be on. The taillamps, sidemarker, and other lamps will not be on. The instrument panel will not be lit up either. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps. To turn off the DRL lamps, turn the exterior lamps control to the OFF position and then release. For vehicles ﬁrst sold in Canada, the transmission must be in the PARK (P) position, before the DRL lamps can be turned off. 3-16 Automatic Headlamp System When it is dark enough outside, the automatic headlamp system will turn on the headlamps at the normal brightness, along with the taillamps, sidemarker, parking lamps, and the instrument panel lights. The radio lights will also be dim. To turn off the automatic headlamp system, turn the exterior lamps switch to the off position and then release it. For vehicles ﬁrst sold in Canada, the transmission must be in the PARK (P) position, before the automatic headlamp system can be turned off. The vehicle has a light sensor located on the top of the instrument panel in the defroster grille that regulates when the automatic headlamps turn on. Be sure it is not covered, or the headlamps will come 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 systems 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. (cid:129) (cid:129) (cid:129) (cid:129) If the vehicle is started in a dark garage, the automatic headlamp system will come on immediately. Once the vehicle leaves the garage, it takes approximately one minute for the automatic headlamp system to change to DRL if it is bright enough 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 3-18. To idle the vehicle with the automatic headlamp system off, turn the control to the off position. The headlamps will also stay on after you exit the vehicle. This feature can be programmed using the Driver Information Center (DIC). See DIC Vehicle Customization (With DIC Buttons) on page 3-68. The regular headlamp system can be turned on when needed. Puddle Lamps If your vehicle has puddle lamps, they come on when the unlock button on the Remote Keyless Entry (RKE) Transmitter is pressed. The lamps time out or turn off once the engine is started. Fog Lamps The vehicle’s fog lamps provide better visibility in foggy or misty conditions. The fog lamp button is located on the left side of the instrument panel. The parking lamps and/or low-beam headlamps must be on for the fog lamps to work. Press the button to turn the fog lamps on while the headlamps are on. Press the button again to turn them off. An indicator light in the button comes on when the fog lamps are in use. Remember, fog lamps alone do not give off as much light as the headlamps. Never use the fog lamps in the dark without turning on the headlamps. The fog lamps go off whenever the high-beam headlamps come on. When the high beams turn off, the fog lamps come on again. 3-17 The fog lamps are cancelled after the ignition is turned off. If you still want to use the fog lamps after the vehicle is restarted, press the fog lamp button 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 and is located next to the exterior lamp control. Push the knob to extend out and then it can be turned. Turn the knob clockwise or counterclockwise to brighten or dim the instrument panel lights. Turning the knob to the farthest clockwise position turns on the dome lamps. Dome Lamps The dome lamps come on when any door is opened. They turn off after all the doors are closed. The dome lamps can also be turned on by turning the instrument panel brightness knob, located next to the exterior lamps control, clockwise to the farthest position. In this position, the dome lamps remain on whether a door is opened or closed. 3-18 Dome Lamp Override The dome lamp override button is located next to the exterior lamps control. k (Dome Off): Press the button in and the dome lamps remain off when a door is opened. Press the button again to return it to the extended position so that the dome lamps come on when a door is opened. Entry Lighting Your vehicle has an illuminated entry feature. When a door is opened, the dome lamps and puddle lamps come on if the dome override feature is not in use. If the dome override feature is used, the lamps do not come on. Exit Lighting The interior lamps come on when the key is removed from the ignition. They turn off automatically in 20 seconds. The lights do not come on if the dome override button is pressed in. Reading Lamps If your vehicle has reading lamps they are located on the overhead console. To turn on the reading lamps, press the button located next to each lamp. To turn them off, press the button again. Your vehicle may also have reading lamps in other locations. To turn the lamps on or off, press the button located next to the lamp. If your vehicle has a DVD Rear Seat Entertainment (RSE) system, press the lamp lenses to turn the lamps on or off. The lamps are ﬁxed and cannot be adjusted. Cargo Lamp The cargo lamps come on by turning the instrument panel brightness control knob to the farthest clockwise position. This knob is located on the instrument panel and also turns on the dome lamps. The cargo lamp can be used if more light is needed in the cargo area of the vehicle or in the top-box storage units. 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 a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following 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. 3-19 EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as Battery Saver Active or Service Battery Charging System. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 3-59. Battery Run-Down Protection This feature shuts off the dome and reading lamps, if they are left on for more than 10 minutes after the ignition is turned off. The cargo lamp shuts off after 20 minutes. This prevents the battery from running down. Accessory Power Outlet(s) Accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular telephone or CB radio. There are two accessory power outlets on the instrument panel, one inside the center ﬂoor console and one on the rear of the center ﬂoor console. To access the accessory power outlet inside the center ﬂoor console, press the button on the side of the console door. See Center Console Storage on page 2-57 for more information. To use an accessory power outlet, remove the protective cap. When not in use, always cover the accessory power outlet with the protective cap. Notice: power outlet, the battery may drain causing your vehicle not to start or damage to the battery. This would not be covered by the warranty. Always unplug all electrical devices when turning off your vehicle. If electrical devices are left plugged into a 3-20 Certain electrical accessories are not 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 accessory power outlets. The accessory power outlets are powered, even when the ignition is in LOCK/OFF. Continuing to use power outlets while the ignition is in LOCK/OFF may cause the vehicle’s battery to run down. 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 If you put papers, pins, or other ﬂammable Ashtray(s) and Cigarette Lighter Your vehicle may have a front ashtray located near the center of the instrument panel. Pull on the door to open it. The ashtray may have a cigarette lighter. 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 remove the ashtray, open the door and pull the ashtray bin toward you. To replace the ashtray, insert the ashtray bin inside the ashtray door and press down until it engages. To use the cigarette lighter, push it in all the way, and let go. When it is ready for use, the lighter pops back out. 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. 3-21 Climate Controls Climate Control System (With Air Conditioning) With this system you can control the heating, cooling, and ventilation for your vehicle.

The outside air mode can be used with all modes, but it cannot be used with the recirculation mode. ?(Recirculation): Press this button to turn the recirculation mode on. When the button is pressed, an indicator light will come on. This mode keeps outside air from entering the vehicle. It can be used to reduce outside air and prevent odors from 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 cannot be used with ﬂoor, defog or defrost modes. If recirculation is selected with one of these modes, the indicator light will ﬂash three times and then turn off. 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. The recirculation mode can be turned off by pressing the outside air button, or by turning off the ignition. #(Air Conditioning): Press this button to turn the air conditioning system on or off. When this button is pressed, an indicator light on the button will come on to let you know the air conditioning is activated. The air conditioning can be selected in any mode as long as the fan switch is on. 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. Defogging and Defrosting Fog or frost 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. To avoid fogging windows on rainy and humid days at temperatures above freezing, run the air conditioning compressor. It is best to avoid the use of the recirculation mode, except when maximum A/C performance is needed or for short times to avoid exterior odors. Turn the right knob to select the defog or defrost mode. -(Defog): This mode clears the windows of fog or moisture and warm the passengers. The air is directed to the windshield, ﬂoor outlets, and side window vents. 0(Defrost): This mode removes fog or frost from the windshield more quickly. A portion of the air is directed to the windshield and the side window vents, with some air directed to the ﬂoor vents. The system will automatically force outside air into the vehicle. The recirculation mode cannot be selected in the defog or defrost mode. When either mode is selected, the system runs the air conditioning compressor, unless the outside temperature is close to freezing. Do not drive the vehicle until all the windows are clear. 3-23 Rear Window Defogger If your vehicle has a rear window defogger it uses a warming grid to remove fog from the rear window. The rear window defogger will only work when the ignition is in RUN. <(Rear): Press this button to turn the rear window defogger on or off. An indicator light on the button will come on to let you know that the rear window defogger is activated. The rear window defogger will only work when the ignition is in RUN. The rear window defogger will stay on for approximately 10 minutes after the button is pressed, unless the ignition is turned to ACC or LOCK. The defogger can also be turned off by pressing the button again or by turning off the engine. 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. 3-24 Climate Control System (Heater Only) With this system you can control the heating and ventilation for your vehicle. 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. Temperature Control: Turn the center knob clockwise or counterclockwise to increase or decrease the temperature inside the vehicle. Use the right knob to select from the following modes: The right knob can be positioned between two modes to select a combination of those two modes. H(Vent): This mode directs air to the instrument panel outlets. )(Bi-Level): This mode directs half of the air to the instrument panel outlets and to the ﬂoor outlets. 6(Floor): This mode directs most of the air to the ﬂoor outlets with some air directed to the windshield, side window outlets, and second row ﬂoor outlets. In this mode, the system will automatically select outside air. Defogging and Defrosting Fog or frost 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. Turn the right knob to select the defog or defrost mode. -(Defog): This mode clears the windows of fog or moisture and warm the passengers. The air is directed to the windshield, ﬂoor outlets, and side window vents. 0(Defrost): This mode removes fog or frost from the windshield more quickly. A portion of the air is directed to the windshield and the side window vents, with some air directed to the ﬂoor vents. The system will automatically force outside air into the vehicle. Do not drive the vehicle until all the windows are clear. 3-25 Driver and Passenger Side Temperature Controls The driver and passenger side temperature buttons are used to adjust the temperature of the air coming through the system on the driver or passenger’s side of the vehicle. The temperature can be adjusted even if the system is turned off. This is possible since outside air always ﬂows 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 cabin temperature. The driver side or passenger side temperature display shows 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 illuminates and both the driver’s side and passenger’s side temperature displays are shown. Dual Automatic Climate Control System The heating, cooling, and ventilation in the vehicle can be controlled with this system. The vehicle also has a ﬂow-through ventilation system described later in this section. Different climate control settings can be selected for the driver and passengers. 3-26 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 changes to show the current temperature(s) and AUTO is lit on the display. The current air delivery mode and fan speed are also displayed for about 5 seconds. When AUTO is selected, the air conditioning operation and air inlet are automatically controlled. The air conditioning compressor may run when the outside temperature is above freezing. The air inlet will normally be set to outside air. If it is hot outside, the air inlet may automatically switch to the recirculate mode to help quickly cool down the air inside the vehicle. The light on the button comes on in recirculation. 2. Set the driver’s and passenger’s temperature. To ﬁnd your comfort setting, start with a 74°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. Be careful not to cover the solar sensor located on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load. For more information on the solar sensor, see “Sensors” later in this section. 3-27 To avoid blowing cold air in cold weather, the system delays turning the fan on until warm air is available. The length of delay depends on the engine coolant temperature. Pressing the fan switch overrides this delay and changes 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 be selected once you have selected vent or bi-level mode. The temperature can also be adjusted using either temperature button. If the air delivery mode or temperature settings are adjusted with the system off, the display illuminates brieﬂy to show the settings and then returns to 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. Manual Operation The air delivery mode or fan speed can be manually adjusted. DC (Fan): These buttons let you manually adjust the fan speed. Press D to increase fan speed and C to decrease fan speed. Pressing either fan button while the system is off turns the system on. Pressing either 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 under automatic control. HG (Mode): Press H and G to manually change the direction of the airﬂow in the vehicle. Repeatedly press either button until the desired mode appears on the display. Pressing either mode button while the system is off changes the air delivery mode without turning the system on. Pressing either mode button while in automatic control places the mode under manual control. The air delivery mode setting is displayed and the AUTO light turns off. The fan remains under automatic control. 3-28 H(Vent): Air is directed to the instrument panel outlets. )(Bi-Level): Air is directed partly 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): Air is directed to the ﬂoor outlets, with some to the windshield, side window outlets, and second row ﬂoor outlets. In this mode, the system will automatically select outside air. -(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. This mode keeps outside air from entering the vehicle. It can be used to reduce outside air and prevent odors from 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 cannot be used with ﬂoor, defog, or defrost modes. If recirculation is selected with one of those modes, the indicator light ﬂashes three times and then 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. The recirculation mode can be turned off by pressing the outside air button, or by turning off the ignition. ; (Outside Air): Press this button to turn on the outside air mode. When this mode is selected, air from outside the vehicle circulates throughout the vehicle. An indicator light on the button comes on to show that it is activated. The outside air mode can be used with all modes, but it cannot be used with the recirculation mode. 3-29 Sensors 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 show that the air conditioning has been activated. Pressing this button when the outside temperature is too cool for air conditioning makes the air conditioning indicator ﬂash three times and then 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 the vehicle to cool down. It also helps the system to operate more efficiently. The air conditioning system removes moisture from the air, so a small amount of water might drip underneath the vehicle while idling or after turning off the engine. This is normal. 3-30 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 in the headliner, 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 on the rearview mirror. 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 the windshield. Use H and G to select the defog or defrost modes. - (Defog): Press this button 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 this mode is selected, 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 a portion 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 close to freezing. Do not drive the vehicle until all the windows are clear. 3-31 Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. <(Rear Window Defogger): If your vehicle has this feature, press this button to turn the defogger on or off. It automatically turns off several minutes after it has been activated. The defogger can also be turned off by turning the engine off. Do not drive the vehicle until all the windows are clear. 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. Heated Mirrors: 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. See Outside Power Mirrors on page 2-39. Outlet Adjustment Use the air outlets located in the center and on the side of the instrument panel to direct the airﬂow. Operation Tips (cid:129) Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the ﬂow of air into your vehicle. (cid:129) Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. (cid:129) Use of non-GM approved hood deﬂectors can adversely affect the performance of the system. Check with your dealer/retailer before adding equipment to the outside of your vehicle. 3-32
