program the transmitter. Because of the steps involved, it may be helpful to have another person assist with programming the transmitter. Be sure to keep the original remote control transmitter for use in other vehicles, as well as, for future programming. Only the original remote control transmitter is needed for Fixed Code programming. The programmed buttons should be erased when the vehicle is sold or the lease ends. See “Erasing Universal Home Remote Buttons” later in this section. Park the vehicle outside of the garage when programming a garage door. Be sure that people and objects are clear of the garage door or gate that is being programmed. Programming Universal Home Remote — Rolling Code For questions or help programming the Universal Home Remote System, call 1-866-572-2728 or go to www.learcar2u.com. Most garage door openers sold after 1996 are Rolling Code units. Programming a garage door opener involves time-sensitive actions, so read the entire procedure before starting. Otherwise, the device will time out and the procedure will have to be repeated. To program up to three devices: 1. From inside the vehicle, press the two outside buttons at the same time for one to two seconds, and immediately release them. 2-72 2. Locate in the garage, the garage door opener receiver (motor-head unit). Locate the “Learn” or “Smart” button. It can usually be found where the hanging antenna wire is attached to the motor-head unit and may be a colored button. Press this button. After pressing this button, complete the following steps in less than 30 seconds. 3. Immediately return to the vehicle. Press and hold the Universal Home Remote button that will be used to control the garage door until the garage door moves. The indicator light, above the selected button, should slowly blink. This button may need to be held for up to 20 seconds. 4. Immediately, within one second, release the button when the garage door moves. The indicator light will blink rapidly until programming is complete. 5. Press and release the same button again. The garage door should move, conﬁrming that programming is successful and complete. To program another Rolling Code device such as an additional garage door opener, a security device, or home automation device, repeat Steps 1 through 5, choosing a different function button in Step 3 than what was used for the garage door opener. If these instructions do not work, the garage door opener is probably a Fixed Code unit. Follow the Programming instructions that follow for a Fixed Code garage door opener. 2-73 To program up to three devices: Programming Universal Home Remote — Fixed Code For questions or help programming the Universal Home Remote System, call 1-866-572-2728 or go to www.learcar2u.com. 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 starting. Otherwise, the device will time out and the procedure will have to be repeated. 1. To verify that the garage door opener is a Fixed Code unit, remove the battery cover on the hand held transmitter supplied by the manufacturer of the garage door opener motor. If there are a row of dip switches similar to the graphic above, the garage door opener is a Fixed Code unit. 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 can have between eight to 12 dip switches depending on the brand of transmitter. 2-74 The garage door opener receiver (motor head unit) could 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 the Universal Home Remote. The motor head dip switch settings can also be used when the original hand held transmitter is not available. Example of Eight Dip Switches with Two Positions Example of Eight Dip Switches with Three Positions The panel of switches might not appear exactly as they do in the examples above, but they should be similar. The switch positions on the hand-held transmitter could be labeled, as follows: (cid:127) A switch in the up position could be labeled as “Up,” “+,” or “On.” (cid:127) A switch in the down position could be labeled as “Down,” “−,” or “Off.” (cid:127) A switch in the middle position could be labeled as “Middle,” “0,” or “Neutral.” 2-75 2. Write down the eight to 12 switch settings from left to right as follows: (cid:127) When a switch is in the up position, write “Left.” (cid:127) When a switch is in the down position, write “Right.” (cid:127) If a switch is set between the up and down position, write “Middle.” The switch settings written down in Step 2 now become the button strokes to be entered into the Universal Home Remote in Step 4. Be sure to enter the switch settings written 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 indicator lights will blink slowly. Enter each switch setting from Step 2 into your vehicle’s Universal Home Remote. You will have two and one-half minutes to complete Step 4. Now press one button on the Universal Home Remote for each switch setting as follows: (cid:127) If you wrote “Left,” press the left button in the vehicle. (cid:127) If you wrote “Right,” press the right button in the vehicle. (cid:127) If you wrote “Middle,” press the middle button in the vehicle. 2-76 5. After entering all of the switch positions, again, ﬁrmly press and release all three buttons at the same time. The indicator lights will turn on. 6. Press and hold the button that will be used to control the garage door until the garage door moves. The indicator light above the selected button should slowly blink. This button may need to be held for up to 55 seconds. 7. Immediately release the button when the garage door moves. The indicator light will blink rapidly until programming is complete. 8. Press and release the same button again. The garage door should move, conﬁrming that programming is successful and complete. To program another Fixed Code device such as an additional garage door opener, a security device, or home automation device, repeat Steps 1-8, choosing a different button in Step 6 than what was used for the garage door opener. Using Universal Home Remote Press and hold the appropriate button for at least half of a second. The indicator light will come on while the signal is being transmitted. Reprogramming Universal Home Remote Buttons Any of the three buttons can be reprogrammed by repeating the instructions. Erasing Universal Home Remote Buttons The programmed buttons should be erased when the vehicle is sold or the lease ends. To erase either Rolling Code or Fixed Code on the Universal Home Remote device: 1. Press and hold the two outside buttons at the same time for approximately 20 seconds, until the indicator lights, located directly above the buttons, begin to blink rapidly. 2. Once the indicator lights begin to blink, release both buttons. The codes from all buttons will be erased. For help or information on the Universal Home Remote System, call the customer assistance phone number under Customer Assistance Offices on page 7-5. 2-77 Instrument Panel Storage Your vehicle may have an instrument panel storage area. It is located above the glove box. Storage Areas Glove Box To open the glove box, lift up on the lever. Cupholders Your vehicle may have cupholders located on and behind the center console and in the rear seat armrest. Pull the loop down on the rear seat armrest to access the cupholders. Pull downward on the lid to use the cupholders behind the center console. To open, press and hold the driver’s side of the handle in and pull out on the exposed portion of the handle. 2-78 Center Console Storage Your vehicle may have an upper and lower center console storage area with cupholders. To access the upper storage area, pull lever (A) up. To access the lower storage area, raise the upper storage bin, then pull lever (B) up. Use the key to lock and unlock the lower storage area. Luggage Carrier The vehicle may have a luggage carrier that can be used to load things on top of the vehicle. The luggage carrier has siderails attached to the roof. It may also have crossrails which can be moved back and forth to help secure cargo. Tie the load to the siderails or siderail supports. Notice: Loading cargo on the luggage carrier that weighs more than 200 lbs (91 kg) or hangs over the rear or sides of the vehicle may damage your vehicle. Load cargo so that it rests on the slats as far forward as possible and against the side rails, making sure to fasten it securely. Do not exceed the maximum vehicle capacity when loading your vehicle. For more information on vehicle capacity and loading, see Loading Your Vehicle on page 4-36. To prevent damage or loss of cargo while you are driving, check to make sure the luggage and cargo are still securely fastened. 2-79 Your vehicle has a Center High-Mounted Stoplamp (CHMSL) located above the rear glass. If items are loaded on the roof of the vehicle, care should be taken not to block or damage the CHMSL unit. Rear Seat Armrest Your vehicle may have a rear seat armrest that contains two cupholders. To access the cupholders, pull the armrest down from the rear seatback. Cargo Management System Your vehicle may have a cargo management system. It is located in the bed of the truck. The system contains three rails located on the front and sides of the bed. The system will include four adjustable cargo tie-downs. The tie-downs can be placed on the upper and lower slides of the rail. Be sure the cargo is properly loaded. (cid:127) If small heavy objects are placed on the roof, cut a piece of 3/8 inch plywood to ﬁt inside the crossrails and siderails to spread the load. Tie the plywood to the siderail supports. (cid:127) Tie the load to the crossrails or the siderail supports. Use the crossrails only to keep the load from sliding. To move a crossrail, lift the release lever, on both sides of the rail, up to loosen it. Slide the crossrail to the desired position balancing the force side to side. Press the release lever on both sides of the rail, down to tighten it. Try to slide the crossrail back and forth slightly to be sure it is tight. (cid:127) If you need to carry long items, move the crossrails as far apart as they will go. Tie the load to the crossrails and the siderails or siderail supports. Also tie the load to the bumpers. Do not tie the load so tightly that the crossrails or siderails are damaged. (cid:127) After moving a crossrail, be sure it is securely locked into the siderail. 2-80 To adjust a tie-down, pull the locator pin out and move the tie-down to another location making sure the locator pin lines up with a locator hole on the rail. The tie-down pin may not be installed correctly if the pin does not line up, turn it over and reinstall. The tie-down will not move when the pin is installed completely. The maximum load for each rail is 500 lbs (227 kg). The rails are notched at each end which allows the tie-downs to be removed and placed on another rail. To remove, pull the locator pin out and slide the tie-down to the end of the rail and pull back. To remove or install cargo tie-downs at the front of the bed, slide the corner cap towards the center of the bed to expose the rail notches. To remove the corner cap, pull either edge away from the rail. To remove the system, loosen the toggle bolts on each rail until they can be removed from the bed of the truck. To replace the system, place the toggle bolts and rails into their original locations and tighten them to a torque setting of 12.5 ft-lbs (17 Y). If the system is removed to install a bed liner, make sure there is no bed liner material in the installation points. Notice: If you tie down cargo using the horizontal slots on the top of the pickup box, you may damage the box. Using the horizontal slots on the top of the pickup box for tie-down locations may cause damage to the pickup box and would not be covered by your warranty. Only use the tie-down loops if you do not have the cargo management system. 2-81 Sunroof If your vehicle has a power sliding sunroof, the ignition needs to be turned to RUN, or the Retained Accessory Power (RAP) must be activated to open or close the sunroof.

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:127) GTurn and Lane Change Signals. See Turn and Lane-Change Signals on page 3-10. (cid:127) 53Headlamp High/Low-Beam Changer. See Headlamp High/Low-Beam Changer on page 3-10. (cid:127) Flash-to-Pass. See Flash-to-Pass on page 3-11. (cid:127) NWindshield Wipers. See Windshield Wipers on page 3-11. (cid:127) LWindshield Washer. See Windshield Washer on page 3-12. For information on the exterior lamps, see Exterior Lamps on page 3-17. 3-9 Turn and Lane-Change Signals The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is ﬁnished, the lever will return automatically. To signal a lane change, raise or lower the lever for less than one second until the arrow starts to ﬂash. This will cause the turn signals to automatically ﬂash three times. It will ﬂash six times if tow-haul mode is active. Holding the turn signal lever for more than one second will cause the turn signals to ﬂash until you release the lever. The lever will return by itself when it is 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 turn signal. 3-10 If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check for burned-out bulbs and a blown fuse. See Fuses and Circuit Breakers on page 5-125. Turn Signal On Chime If your 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 ON will also appear in the Driver Information Control (DIC). To turn the chime and message off, move the turn signal lever to the off position. 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 your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your 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. 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 5-67. 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. 3-11 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. Rainsense™ II Wipers If your vehicle has Rainsense™ II windshield wipers, the moisture sensor is located next to the inside rearview mirror and is mounted on the windshield. When active, these sensors are able to detect moisture on the windshield and automatically turn on the wipers. To turn on the Rainsense™ feature, the wipers must be set to one of the ﬁve delay settings on the multifunction lever. Each of the ﬁve settings adjusts the sensitivity of the rainsensor. Since different drivers have different setting preferences, it is recommended that the mid-range setting (position 3) be used initially. For more wipes, select the higher settings; for fewer wipes, select the lower settings located closer to the off position on the multifunction lever. The rainsensor will automatically control the frequency of the wipes from the off setting to the high speed setting according to the weather conditions. The wipers can be left in a rainsense mode even when it is not raining. When Rainsense™ is active, the headlamps will turn on automatically if the exterior lamp control is in the AUTO position and the wipers are active. Notice: Going through an automatic car wash with the wipers on can damage them. Turn the wipers off when going through an automatic car wash. 3-12 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. Cruise Control {CAUTION: 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. 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, a speed of about 25 mph (40 km/h) or more can be maintained 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). 3-13 When the brakes are applied, cruise control is turned off. For vehicles with an Allison® automatic transmission, see “Grade Braking and Cruise Grade Braking (Allison Transmission) under Tow/Haul Mode on page 2-34 for an explanation of how cruise control interacts with the Range Selection Mode, tow/haul and grade braking systems. For vehicles with the StabiliTrak® system that begins to limit wheel spin while you are using cruise control, the cruise control will automatically disengage. See StabiliTrak® System on page 4-6. When road conditions allow the cruise control to be safely used again, it can be turned back on. The cruise control buttons are located on left side of the steering wheel. 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 to make the vehicle accelerate or resume to a previously set speed. SET − (Set/Coast): Press to set the speed or make the vehicle decelerate. [ (Cancel): Press to cancel cruise control without erasing the set speed from memory. 3-14 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. Resuming a Set Speed If the brakes are applied 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:127) Press and hold the +RES button on the steering wheel until the desired speed is reached, then release it. (cid:127) To increase vehicle speed in small increments, press the +RES button. Each time this is done, the vehicle goes about 1 mph (1.6 km/h) faster. 3-15 Reducing Speed While Using Cruise Control To reduce the vehicle speed while using cruise control: (cid:127) Press and hold the SET– button on the steering wheel until the desired lower speed is reached, then release it. (cid:127) To slow down in very small amounts, press the SET– button on the steering wheel brieﬂy. Each time this is done, the vehicle goes 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. 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. When the brakes are applied the cruise control turns off. Ending Cruise Control There are three ways to end cruise control: (cid:127) Step lightly on the brake pedal. (cid:127) Press the cancel button on the steering wheel. (cid:127) Press the On/Off button on the steering wheel. Erasing Speed Memory The cruise control set speed memory is erased, when the cruise control or the ignition is turned off. 3-16 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:127) Headlamps (cid:127) Taillamps (cid:127) Parking Lamps (cid:127) License Plate Lamps (cid:127) 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). AUTO (Automatic): Turn the control to this position to automatically turn on the headlamps at normal brightness, together with the following: (cid:127) Parking Lamps (cid:127) Instrument Panel Lights (cid:127) Taillamps (cid:127) 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 3-56. ;(Parking Lamps): Turn the control to this position to turn on the parking lamps together with the following: (cid:127) Instrument Panel Lights (cid:127) Taillamps (cid:127) License Plate Lamps 3-17 2(Headlamps): Turn the control to this position to turn on the headlamps together with the following: (cid:127) Parking Lamps (cid:127) Instrument Panel Lights (cid:127) Taillamps (cid:127) License Plate Lamps 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 your ignition is off and a door is open. To disable the chime, turn the light off. 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: (cid:127) The ignition is on. (cid:127) The exterior lamps control is in AUTO. (cid:127) The transmission is not in PARK (P). (cid:127) 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. 3-18 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. 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 3-21. 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 3-76. The regular headlamp system can be turned on when needed. 3-19 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 -(Fog Lamps): If your vehicle has fog lamps, the control is located next to the exterior lamps control on the instrument panel, to the left of the steering column. The ignition must be in the ON/RUN position for the fog lamps to come on. Press the button to turn the fog lamps on or off. A light will come on in the instrument panel cluster. When the fog lamps are turned on, the parking lamps automatically turn on. When the headlamps are changed to high-beam, the fog lamps also go off. When the high-beam headlamps are turned off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. 3-20 Auxiliary Roof Mounted Lamp If your vehicle has this feature, this button includes wiring provisions for a dealer or a qualiﬁed service center to install an auxiliary roof lamp. This button is located on the overhead console. When the wiring is connected to an auxiliary roof mounted lamp, pressing the bottom of the button will activate the lamp and illuminate an indicator light at the bottom of this button. Pressing the top of the button will turn off the roof mounted lamp and indicator. The emergency roof lamp circuit is fused at 30 amps, so the total current draw of the attached lamps should be less than this value. The attachment points for the roof lamp circuits are two blunt cut wires located above the overhead console, a dark green switched power wire and a black ground wire. For further information on roof mount emergency lamp installation, please visit the GM Upﬁtter website at www.gmupﬁtters.com or contact your dealer. If your vehicle has this button, your vehicle may have the snow plow prep package. For further information see Adding a Snow Plow or Similar Equipment on page 4-43. 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. 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 the doors are opened, the dome lamps will come on if the dome override button is in the extended position. If the dome override button is pressed in, the lamps will 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. 3-21 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. 3-22 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 3-66. 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. The vehicle may have two accessory power outlets located below the climate control system, or may have one accessory power outlet and one cigarette lighter. The cigarette lighter is designed to ﬁt only in the receptacle closest to the driver. There may be another accessory power outlet in the rear cargo area. If the vehicle has a ﬂoor console, there is an accessory power outlet inside the storage bin and one on the rear of the ﬂoor console. 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: Leaving electrical equipment plugged in for an extended period of time while the vehicle is off will drain the battery. Power is always supplied to the outlets. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum 20 ampere rating. 3-23 Certain power accessory plugs may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/retailer for additional information on the accessory power plugs. 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 the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not 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 papers, pins, or other ﬂammable items 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: are put 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. 3-24 Climate Controls Climate Control System (With Air Conditioning ) With this system you can control the heating, cooling, 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 half to the ﬂoor outlets. 6(Floor): This mode directs most of the air to the ﬂoor outlets with some air directed to the windshield and side window outlets. In this mode, the system will automatically select outside air. Recirculation cannot be selected in ﬂoor mode. The right knob may also be used to select the defrost and defog mode. For more information, see “Defogging and Defrosting” later in this section. 3-25 : (Outside Air): Press this button to turn the outside air mode on. When the button is pressed, an indicator light will come on. When this mode is on, outside air will circulate throughout the 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. 3-26 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. 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 the vehicle warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. 3-27 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. 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. 3-28 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. 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. Different climate control settings can be selected for the driver and passengers. 3-29 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. 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. 3-30 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. 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. 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. 3-31 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. 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. 3-32 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. 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. 3-33 Sensors The solar sensor, located in the defrost grille, in the middle of the instrument panel, monitors the solar radiation. Do not cover the solar sensor or the system will not work properly. The interior temperature sensor, located 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. 3-34 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.

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 2-61. Outlet Adjustment Use the air outlets located in the center and on the side of the instrument panel to direct the airﬂow. Use the thumbwheels near the air outlets to open or close off the airﬂow. Operation Tips (cid:127) Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the ﬂow of air into the vehicle. (cid:127) Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. (cid:127) 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. 3-35 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 also has a Driver Information Center (DIC) that works along with warning lights and gages. See DIC Warnings and Messages on page 3-66 for more information. 3-36 Instrument Panel Cluster United States Light Duty Premium version shown. Canada, Uplevel, Base, Heavy Duty Clusters similar. Your instrument 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 and many other things you will need to know to drive safely and economically. If your vehicle has the DURAMAX® Diesel engine, see the DURAMAX® Diesel manual for more information. 3-37 Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). Engine Hour Meter Display The Driver Information Center (DIC) can also display the number of hours the engine has run. To display the engine hours, turn the ignition off, press and hold the reset button for at least four seconds. The hour meter will be displayed for up to 30 seconds, or until the ignition is turned on. See DIC Operation and Displays (With DIC Buttons) on page 3-57 or DIC Operation and Displays (Without DIC Buttons) on page 3-63 for more information. Trip Odometer The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Press the reset button, located on the instrument panel cluster next to the voltmeter, to toggle between the trip odometer and the regular odometer. Holding the reset button for approximately one second while the trip odometer is displayed will reset it. To display the odometer reading with the ignition off, press the reset button. See DIC Operation and Displays (With DIC Buttons) on page 3-57 or DIC Operation and Displays (Without DIC Buttons) on page 3-63 for more information. Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). See “Grade Braking (Allison Transmission®)” under Tow/Haul Mode on page 2-34 for more information. 3-38 Safety Belt Reminders Safety Belt Reminder Light When the engine is started, a chime will sound for several seconds to remind people to buckle their safety belts. The driver safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. Passenger Safety Belt Reminder Light For vehicles with Passenger Safety Belt Reminder Lights, 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 1-81 for more information. The passenger safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. If the driver’s belt is 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. 3-39 {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. 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 3-66 for more information. 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 1-69. 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. 3-40 Airbag Off Light If your vehicle has an airbag on-off switch, it also has a passenger airbag status indicator located in the overhead console. When you turn the right front passenger’s airbag off, this light will come on and stay on to remind you that the airbag has been turned off. This light will go off when you turn the airbag back on again. See Airbag Off Switch on page 1-78 for more on this, including important safety information. United States Canada When you start your vehicle, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, will light for several seconds as a system check. Then, after several more seconds, the status indicator ON or OFF, or either the on or off symbol, will light to let you know the status of the right front passenger’s frontal airbag. United States Canada 3-41 When you manually turn the right front passenger’s airbag off using the airbag on-off switch in the glove box, the indicator light OFF or the off symbol will come on and stay on to remind you that the airbag has been turned off. This light will go off when you turn the airbag on. See Airbag Off Switch on page 1-78 for more on this, including important safety information. {CAUTION: If the right front passenger’s airbag is turned off for a person who is not in a risk group identiﬁed by the national government, that person will not have the extra protection of an airbag. In a crash, the airbag will not be able to inﬂate and help protect the person sitting there. Do not turn off the passenger’s airbag unless the person sitting there is in a risk group identiﬁed by the national government. See Airbag Off Switch on page 1-78 for more on this, including important safety information. 3-42 {CAUTION: If the airbag readiness light ever comes on when you have turned off the airbag, it means that something may be wrong with the airbag system. The right front passenger’s airbag could inﬂate even though the switch is off. If this ever happens, do not let anyone whom the national government has identiﬁed as a member of a passenger airbag risk group sit in the right front passenger’s position (for example, do not secure a rear-facing child restraint in the right front passenger’s seat) until you have your vehicle serviced. See Airbag Off Switch on page 1-78 and Airbag Readiness Light on page 3-40 for more on this, including important safety information. If the word ON or the on symbol is lit, it means that the right front passenger’s frontal airbag is enabled (may inﬂate). See Airbag Off Switch on page 1-78 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 airbag on-off switch. See your dealer/retailer for service. Passenger Airbag Status Indicator If your vehicle has the passenger sensing system, your overhead console will have 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). {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. 3-43 {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 1-81 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 3-40 for more on this, including important safety information. 3-44 Charging System Light Voltmeter Gage This light will come on brieﬂy when you turn on the ignition key, but the engine is not running, as a check to show you it is working. Your vehicle may have a voltmeter gage. It should go out once the engine is running. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-66 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If you must drive a short distance with the light on, be certain to turn off all the accessories, such as the radio and air conditioner. When the ignition is on, this gage indicates the battery voltage. When the engine is running, this gage shows the condition of the charging system. The gage may transition from a higher to lower or a lower to higher reading, this is normal. If the vehicle is operating outside the normal operating range, the charging system light will come on. See Charging System Light on page 3-45 for more information. The voltmeter gage may also read lower when in fuel economy mode. This is normal. 3-45 Readings outside the normal operating range may also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. You can only drive for a short time with the readings outside the normal operating range. If you must drive, turn off all unnecessary accessories. Readings outside the normal operating range indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible. Brake System Warning Light With the ignition on, the brake system warning light will come on when you set the parking brake. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 5 mph (8 km/h). 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 and a chime sounds there could be a brake problem. Have your brake system inspected right away. This light may also come on due to low brake ﬂuid. See Brakes on page 5-43 for more information. United States Canada 3-46 This light should come on brieﬂy when you turn the ignition key to RUN. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Anti-lock Brake System (ABS) Warning Light {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. 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 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 4-50. For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started. 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, your vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, your vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-46. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-66 for all brake related DIC messages. 3-47 StabiliTrak® Indicator Light Engine Coolant Temperature Gage If equipped, this warning light should come on brieﬂy when the engine is started. If the warning light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak® system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly. This light will also ﬂash when the StabiliTrak® system is active. If the StabiliTrak® system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. See StabiliTrak® System on page 4-6 for more information. United States Canada This gage shows the engine coolant temperature. It also provides an indicator of how hard your vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If you are pulling a load or going up hills, it is normal for the temperature to ﬂuctuate and go over the 235°F (113°C) mark. However, if the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 5-32. 3-48 Tire Pressure Light This light comes on brieﬂy
