indicator light begins to ﬂash, after 20 seconds. Do not hold down the buttons for longer than 30 seconds and do not repeat this step to program a second and/or third hand-held transmitter to the remaining two Universal Home Remote buttons. 2. Position the end of your hand-held transmitter about 1 to 3 inches (3 to 8 cm) away from the Universal Home Remote buttons while keeping the indicator light in view. 3. Simultaneously press and hold both the desired Universal Home Remote button and the hand-held transmitter button. Do not release the buttons until Step 4 has been completed. Some entry gates and garage door openers may require you to substitute Step 3 with the procedure noted in “Gate Operator and Canadian Programming” later in this section. 4. The indicator light will ﬂash slowly at ﬁrst and then rapidly after Universal Home Remote successfully receives the frequency signal from the hand-held transmitter. Release both buttons. 6. Locate in the garage, the garage door opener receiver (motor-head unit). Locate the “Learn” or “Smart” button. This can usually be found where the hanging antenna wire is attached to the motor-head unit. 5. Press and hold the newly-trained Universal Home Remote button and observe the indicator light. If the indicator light stays on continuously, programming is complete and your device should activate when the Universal Home Remote button is pressed and released. To program the remaining two Universal Home Remote buttons, begin with Step 2 under “Programming Universal Home Remote.” Do not repeat Step 1 as this will erase all of the programmed channels. If the indicator light blinks rapidly for two seconds and then turns to a constant light, continue with Steps 6 through 8 following to complete the programming of a rolling-code equipped device, most commonly, a garage door opener. 7. Firmly press and release the “Learn” or “Smart” button. The name and color of the button may vary by manufacturer. You will have 30 seconds to start Step 8. 8. Return to the vehicle. Firmly press and hold the programmed Universal Home Remote button for two seconds, then release it. Immediately press and hold the same button a second time for two seconds, then release it. Immediately, press and hold the same button a third time for two seconds, then release. The Universal Home Remote should now activate your rolling-code equipped device. To program the remaining two Universal Home Remote buttons, begin with Step 2 of “Programming Universal Home Remote.” You do not want to repeat Step 1, as this will erase all previous programming from the Universal Home Remote buttons. 141 Gate Operator and Canadian Programming Canadian radio-frequency laws require transmitter signals to time out or quit after several seconds of transmission. This may not be long enough for Universal Home Remote to pick up the signal during programming. Similarly, some U.S. gate operators are manufactured to time out in the same manner. If you live in Canada, or you are having difficulty programming a gate operator or garage door opener by using the “Programming Universal Home Remote” procedures, regardless of where you live, replace Step 3 under “Programming Universal Home Remote” with the following: Continue to press and hold the Universal Home Remote button while you press and release every two seconds (cycle) the hand-held transmitter button until the frequency signal has been successfully accepted by the Universal Home Remote. The Universal Home Remote indicator light will ﬂash slowly at ﬁrst and then rapidly. Proceed with Step 4 under “Programming Universal Home Remote” to complete. 142 Using Universal Home Remote Press and hold the appropriate Universal Home Remote button for at least half of a second. The indicator light will come on while the signal is being transmitted. Erasing Universal Home Remote Buttons To erase programming from the three Universal Home Remote buttons do the following: 1. Press and hold down the two outside buttons until the indicator light begins to ﬂash, after 20 seconds. Do not hold the two outside buttons for longer than 30 seconds. 2. Release both buttons. The Universal Home Remote is now in the training (learning) mode and can be programmed at any time beginning with Step 2 under “Programming Universal Home Remote” shown earlier in this section. Individual buttons cannot be erased, but they can be reprogrammed. See “Reprogramming a Single Universal Home Remote Button” following this section. Reprogramming a Single Universal Home Remote Button To program a device to Universal Home Remote using a Universal Home Remote button previously trained, follow these steps: 1. Press and hold the desired Universal Home Remote button. Do not release the button. 2. The indicator light will begin to ﬂash after 20 seconds. While still holding the Universal Home Remote button, proceed with Step 2 under “Programming Universal Home Remote” shown earlier in this section. For additional information on Universal Home Remote, see Customer Assistance Offices on page 452. Storage Areas Glove Box Open the glove box by pulling the bottom of the handle upward.

Use the provided crossrail key to unlock the crossrail end cap by turning it counterclockwise. Luggage Carrier If your vehicle has this feature, you can load cargo on your vehicle. The luggage carrier consists of siderails attached to the roof. The crossrails attach into the siderails and can be moved back and forth to accommodate various cargo sizes. Notice: Loading cargo on the luggage carrier that weighs more than 250 lbs. (113 kg) or hangs over the rear or sides of the vehicle may damage your vehicle. Load cargo only on top of the crossrails and tie the cargo down to the crossrail support cargo tie-down loops, 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 289. 144 2. Remove the end cap. 3. Pull the lever labeled “PULL” from left to right to loosen the crossrail. 4. Repeat Steps 1 through 3 to the opposite end of the crossrail. 5. Once both sides of the crossrail are loose, adjust the crossrail to the desired position. 6. Push the lever labeled “PULL” from right to left to lock the crossrail in place. 7. Reinstall end cap and lock by turning the key clockwise. 8. Repeat Steps 5 through 7 to the opposite end of the crossrail. 145 Stop Tabs If your vehicle has a sunroof, it will have a crossrail stop tab placed in the siderail. This tab prevents you from moving the crossrails past the opening of the sunroof and loading cargo too far forward. Your vehicle may have cargo tie downs. Once you load the cargo onto the crossrails, secure it by tying it down to the cargo tie downs. Do not load cargo directly on the roof of your vehicle. See Cargo Tie Downs on page 146 for more information. Rear Storage Area Your vehicle has a rear storage area located on the passenger’s side of the cargo area. To open, pull the two tabs out and open lid. Convenience Net Your vehicle may have a convenience net in the rear of the vehicle. Put small loads behind the net. The net is not for heavier loads. Store them as far forward as you can. If you put items onto the cargo cover, Cargo Cover Notice: the weight of the items could cause the attachment clips to break. You would no longer be able to attach and use the cargo cover. The repairs would not be covered by your warranty. Never put anything on top of the cargo cover. If your vehicle has a cargo cover, you can use it to cover items in the rear of the vehicle. Remove the cover from its pouch and place the loops found on each corner of the cover, over the two pegs in each corner of the rear if the vehicle. When it is not in use, fold up the cover and return it to the pouch. Cargo Tie Downs Your vehicle may have four cargo tie-downs. These tie-downs are located in tracks on the roof of the vehicle. Each tie-down can be moved to anywhere on the track. To loosen, turn the tie-down counterclockwise until it moves freely in the track. To tighten, turn the tie-down clockwise. 146 Sunroof Your vehicle may have a power sliding sunroof. The ignition must be on or in ACC, or Retained Accessory Power (RAP) must be active.

Horn To sound the horn, press the horn symbol on the steering wheel pad. Tilt Wheel A tilt wheel allows the steering wheel to be adjusted before driving. It can be raised to allow more room for the driver to enter and exit the vehicle. Hazard Warning Flashers Your hazard warning ﬂashers let you warn others. They also let police know you have a problem. Your front and rear turn signal lamps will ﬂash on and off. The hazard warning ﬂasher button is located in the center of the instrument panel. Your hazard warning ﬂashers work no matter what position your key is in, and even if the key is not in the ignition switch. Press the button to make the front and rear turn signal lamps ﬂash on and off. Press the button again to turn the ﬂashers off. When the hazard warning ﬂashers are on, your turn signals will not work. 154 Turn Signal/Multifunction Lever The tilt lever is located on the left side of the steering column, under the turn signal lever. To tilt, hold the steering wheel and pull the tilt lever toward you. Move the wheel to a comfortable level, then release the tilt lever to lock the wheel in place. Do not adjust the steering wheel while driving. The lever on the left side of the steering column includes the following: (cid:127) G Turn and Lane Change Signals. See Turn Signal/Multifunction Lever on page 155. (cid:127) 53 Headlamp High/Low-Beam Changer. See Headlamp High/Low-Beam Changer on page 157. (cid:127) Flash-to-Pass. See Flash-to-Pass on page 157.

See Cruise Control on Washer on page 158. page 159. 155 Turn and Lane-Change Signals The turn signal has one upward (for right) and one downward (for left) positions. These positions allow you to signal a turn or a lane change. To signal a turn, move the lever all the way up or down. When the turn is ﬁnished, the lever will automatically return to the off position. To signal a lane change, raise or lower the lever until the arrow starts to ﬂash. Hold it there until the change is completed. The lever will return by itself when released. An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when signaling a turn, check for a burned-out bulb or a blown fuse. For bulb replacement, see Taillamps, Turn Signal, Stoplamps and Back-up Lamps on page 363. For a blown fuse or circuit breaker, see Fuses and Circuit Breakers on page 417 Turn Signal On Chime If a turn signal is left on for more than 3/4 of a mile (1.2 km), a chime will sound at each ﬂash of the turn signal and the message TURN SIGNAL will also appear in the DIC. To turn the chime and message off, move the turn signal lever to the off position. See “TURN SIGNAL” under DIC Warnings and Messages on page 196 DIC Warnings and Messages for more information. As you signal a turn or a lane change, if the arrows ﬂash more quickly than normal, a signal bulb may be burned out and other drivers will not see your vehicle’s turn signal. 156 Headlamp High/Low-Beam Changer 53(Headlamp High/Low Beam Changer): To change the headlamps from low to high beam, push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this indicator light on the instrument panel cluster will also be on. Flash-to-Pass This feature lets you use the high-beam headlamps to signal a driver in front of you that you want to pass. It works even if the headlamps are in the automatic position. To use it, pull the turn signal lever toward you, then release it. If your headlamps are in the automatic position or on low beam, your high-beam headlamps will turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster will come on. Release the lever to return to normal operation. Windshield Wipers You control the windshield wipers by turning the band with the wiper symbol on it. 8(Mist): Turn the band to mist for a single wiping cycle. Hold it there until the wipers start. Then let go. The wipers will stop after one wipe. Hold the band on mist longer, if more wipes are needed. N(Delay): The wiper speed can be set for long or short delays between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay. 157 6 (Low Speed): For steady wiping at low speed, turn the band away from you to the ﬁrst solid position past the delay settings. 1 (High Speed): For high-speed wiping, turn the band to the second solid position past the delay settings. 9(Off): Move the band to off, to stop the wipers. Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. Windshield wipers work in all power modes, except when set to LOCK. After the engine is turned off, wipers will work in Retained Accessory Power (RAP) mode until a door is opened. See Retained Accessory Power (RAP) on page 103. Windshield Washer L(Washer Fluid): There is a paddle marked with the windshield washer symbol at the top of the multifunction lever. To spray washer ﬂuid on the windshield, push the paddle. The wipers will clear the window and then either stop or return to your preset speed. {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer ﬂuid can form ice on the windshield, blocking your vision. 158 Rear Window Wiper/Washer This knob is located on the instrument panel below the climate controls. Cruise Control With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). 9(Off): This position turns the system off. Z (Rear Wiper): To turn the rear wiper on, turn the knob to either 1 or 2. For a slower wiping speed, turn the knob to 1. For a faster wiping speed, turn the knob to 2 0 (Off): To turn the wiper off, turn the knob to this symbol. =(Washer Fluid): To wash and wipe the window, press the button within the knob with this symbol. The rear window washer uses the same ﬂuid bottle as the windshield washer. However, the rear window washer will run out of ﬂuid before the windshield washer. If you can wash your windshield but not your rear windows, check the ﬂuid level. R(On): This position activates the system. + (Resume/Accelerate): Move the lever to this symbol to make the vehicle accelerate or resume to a previously set speed. rT(Set): Press this button to set the speed. 159 Cruise control will not work if your parking brake is set, or if the master cylinder brake ﬂuid level is low. If you apply your brakes, the cruise control shuts off. Setting Cruise Control {CAUTION: {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. 1. Move the cruise control switch to on. 2. Get up to the speed desired. 3. Press in the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal. The cruise control disengages, if the vehicle has the Traction Control System (TCS) and it begins to limit wheel spin. See Traction Control System (TCS) on page 241. When road conditions allow you to safely use it again, you can turn cruise control back on. 160 The cruise symbol on the instrument panel comes on when the cruise control is engaged. Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake or step on the clutch. This, of course, disengages the cruise control. But you do not need to reset it. Once you are going about 25 mph (40 km/h) or more, you can move the cruise control switch brieﬂy from on to resume/accelerate. The vehicle will go back to the chosen speed and stays there. If you hold the switch at resume/accelerate the vehicle will keep going faster until you release the switch or apply the brake. Do not hold the switch at resume/accelerate, unless you want the vehicle to go faster. Increasing Speed While Using Cruise Control There are two ways to go to a higher speed: (cid:127) Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You will now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off. (cid:127) Move the cruise switch from on to resume/ accelerate. Hold it there until you get up to the speed you want, and then release the switch. To increase your speed in very small amounts, move the switch brieﬂy to resume/accelerate. Each time you do this, your vehicle goes about 1 mph (1.6 km/h) faster. Reducing Speed While Using Cruise Control (cid:127) Press and hold the set button until you reach the desired lower speed, then release it. (cid:127) To slow down in very small amounts, brieﬂy press the set button. Each time you do this, you will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle slows down to the cruise control speed you set earlier. 161 Exterior Lamps The control on the driver’s side of your instrument panel operates the exterior lamps. O(Exterior Lamps): Turn the knob, located to the right of this symbol, to choose one of the four exterior lamp positions. Using Cruise Control on Hills How well your cruise control works on hills depends upon your speed, load, and the steepness of the hills. When going up steep hills, you might want to step on the accelerator pedal to maintain the vehicle speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle speed down. Of course, applying the brake turns off the cruise control. Many drivers ﬁnd this to be too much trouble and do not use cruise control on steep hills. Ending Cruise Control To turn off the cruise control, do one of the following: (cid:127) Step lightly on the brake pedal. (cid:127) Move the cruise control switch to off. (cid:127) Lightly tap or press the clutch, if you have a manual transmission. Erasing Speed Memory When you turn off the cruise control or the ignition, the cruise control set speed memory is erased. 162 9(Off): Turn the knob to this position to turn off all exterior lamps, including the Daytime Running Lamps (DRL). This is a momentary control that will spring back to AUTO when released. Vehicles ﬁrst sold in Canada do not have the DRL disable feature available. Vehicles ﬁrst sold in Canada cannot turn off the DRL unless the following conditions are met: (cid:127) The vehicle has an automatic transmission. (cid:127) The gear position is in PARK (P). (cid:127) The headlamp switch is turned to the Off position. AUTO (Automatic): Turn the knob to this position to automatically turn on the headlamps at normal brightness, together with the following: (cid:127) Sidemarker Lamps (cid:127) Taillamps (cid:127) Parking Lamps (cid:127) Due to the momentary switch design, your automatic headlamps may be disabled even if the control is in the AUTO position. Instrument Panel Lights To enable automatic lighting, do any of the following: (cid:127) Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. (cid:127) Turn the headlamp control from the parking lamp position to AUTO. (cid:127) Turn the headlamp control from the headlamp position to AUTO. To disable automatic lighting, do any of the following: (cid:127) Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. (cid:127) Turn the headlamp control from AUTO to the parking lamp position. (cid:127) Turn the headlamp control from AUTO to the headlamp position. See Automatic Headlamp System on page 165 for more information. 163 Vehicles ﬁrst sold in Canada with an automatic transmission cannot turn off automatic headlamps unless the gear position is in PARK (P) and the headlamp switch is turned to the Off position. Vehicles ﬁrst sold in Canada with a manual transmission can turn off the automatic headlamps with the headlamp control; however, the parking lamps will remain on. ;(Parking Lamps): Turn the knob to this position to turn on the parking lamps, together with the following: (cid:127) Sidemarker Lamps (cid:127) Taillamps (cid:127) License Plate Lamps (cid:127) 2(Headlamps): Turn the knob to this position to turn on the headlamps, together with the previously listed lamps and lights. You can switch your headlamps from low to high beam by pushing the turn signal/multifunction lever toward the instrument panel. Instrument Panel Lights Headlamps on Reminder A headlamp reminder chime will sound if the following conditions are met: (cid:127) The driver door is open. (cid:127) Parking lamps or headlamps are manually turned on. (cid:127) The key is either not in the ignition switch, or it is in the LOCK position of the ignition switch. The headlamp reminder cannot be turned off if the conditions listed above are met. In the automatic mode, the headlamps turn off once the ignition is in ACC. 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. 164 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) if you have an automatic transmission. (cid:127) The light sensor determines it is daytime. When the DRL are on, no other lamps are on. The instrument panel will not be lit up either. For vehicles ﬁrst sold in Canada, if parking lamps are manually turned on, DRL will stay on. When it begins to get dark, the automatic headlamp system will switch from DRL to the headlamps. As with any vehicle, you should turn on the regular headlamp system when you need it. To turn off the DRL, see Exterior Lamps on page 162. Vehicles ﬁrst sold in Canada cannot turn off DRL unless certain conditions are met. See Exterior Lamps on page 162. Automatic Headlamp System When it is dark enough outside, the automatic headlamp system will turn on after the transmission has been shifted from PARK (P) to DRIVE (D). The headlamps, taillamps, sidemarker, parking lamps, roof marker lamps, and the instrument panel lights will turn on at normal brightness. The radio lights will become more dim when the headlights are off compared to when the headlights are on. Your vehicle has a light sensor located on the top of the instrument panel. Be sure it is not covered, or the system will be on whenever the ignition is on. The system may also turn on the headlamps when driving through a parking garage, heavy overcast weather, or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp system so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system will only be affected when the light sensor detects a change in lighting lasting longer than the delay. 165 If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 167. Off-Road Lamps The off-road lamps, if the vehicle has them, provide auxiliary lighting when the vehicle is used off road. These lamps are not intended to be used in place of existing vehicle lighting. The lamps are not to be used on any public street or highway and are to be covered when not in use. Check your state and local laws before installing or using any auxiliary lighting. In some states it may be necessary to remove the roof lamps when operating the vehicle on the highway. 166 Roof Mounted Off-Road Light Switch Lower Grille Off-Road Light Switch The switches for the off-road lamps are located in the center of the instrument panel below the climate controls. One switch is used for the front lower-grille mounted off-road lamps, if the vehicle has them, and the other switch is used for the roof-mounted off-road lamps, if the vehicle has them. To use the lamps, remove the covers from the lamps and press the switch to turn them on or off. An indicator light on the switch will turn on when the lamps are on. Notice: Turning on the off-road lamps before removing the lamp covers could damage the off-road lamps and the covers. Always remove the covers before turning on the off-road lamps. The off-road lamps remain on even after the ignition is turned off. The off-road lamp switch must be pressed to turn them off. Fog Lamps Your vehicle has fog lamps. You can use them for better vision in foggy or misty conditions. Your parking lamps and/or low-beam headlamps must be on for your fog lamps to work. The fog lamp button is located in the exterior lamps control. Press the button to turn the fog lamps on while the headlamps or parking lamps are on. Press the button again to turn them off. An indicator light will glow in the button when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use your fog lamps in the dark without turning on the headlamps. The fog lamps will go off whenever your high-beam headlamps come on. When the high beams go off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. Instrument Panel Brightness D(Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The thumbwheel for this feature is located next to the exterior lamp control. Turn the thumbwheel up or down to brighten or dim the instrument panel lights and the radio display. The instrument panel lights, cluster, and radio display do not dim to complete darkness. Turn the thumbwheel all the way up to turn the dome lamps on. Dome Lamp The dome and footwell lamps will come on when you open a door. The dome lamps are located in the cargo and front area of the vehicle. You can also turn the dome and footwell lamps on by turning the thumbwheel, located next to the exterior lamps control, all the way up. In this position, the lamps will remain on whether a door is opened or closed. 167 Dome Lamp Override E(Dome Lamp Override): You can use the dome override button, located below the exterior lamps control, to set the dome and footwell lamps to come on automatically when a door is opened, or to remain off. To turn the lamps off, press the button into the in position. With the button in this position, the dome lamps will remain off when the doors are open. To return the lamps to automatic operation, press the button again and return it to the out position. With the button in this position, the dome lamps will come on when you open a door. Exit Lighting With exit lighting, the interior lamps will come on when you remove the key from the ignition. The lamps will not come on if the dome override button is pressed in. Reading Lamps Your vehicle has reading lamps. Press the button located next to the lamp to turn them on or off. These lamps will not come on with the dome lamps. 168 Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery’s state of charge is low, the voltage is raised slightly to quickly put the charge back in. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage, you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following loads are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. Battery Run-Down Protection This feature shuts off the dome lamp if it is left on for more than 20 minutes when the ignition is in LOCK. This will help prevent your battery from running down. Accessory Power Outlet(s) Your vehicle has accessory power outlets. With accessory power outlets you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. Your vehicle has two accessory power outlets located on the lower part of the instrument panel below the climate control system and there may be one located in the rear cargo area. A small cap must be pulled down to access an accessory power outlet. When not using an outlet, be sure to cover it with the protective cap. Notice: Leaving electrical equipment on for extended periods will drain the battery. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum amperage rating of 20 amperes. Certain electrical accessories may not be compatible with the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer for additional information on accessory power outlets. Notice: Adding any electrical equipment to your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. Notice: can cause damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Improper use of the power outlet 169 If you put papers, pins, or other Ashtray(s) and Cigarette Lighter Your vehicle may have an ashtray and cigarette lighter. Your ashtray is located in your center console area. The ashtray can be removed for cleaning. When the ashtray is removed, this area can also be used as a cupholder. Notice: ﬂammable items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your vehicle. Never put ﬂammable items in the ashtray. To use the lighter, press it in all the way, and let go. When it’s ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating will not allow the lighter to back away from the heating element when it is hot. Damage from overheating may occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating. 170 Climate Controls Climate Control System This system controls the heating, cooling, and ventilation of the vehicle. In-between modes are available by moving the right control knob between modes with symbols. The in-between mode will be a combination of the two modes that the control is centered between. Temperature: Turn the left knob on the control panel to adjust the temperature of the air in the vehicle. Turn the knob clockwise or counterclockwise to increase or decrease the temperature. #(Air Conditioning): Press the left knob on the control panel to turn the air conditioning system on or off. An indicator light on the button will be lit when the air conditioning is turned on. This system cools and dehumidiﬁes the air entering the vehicle. The air conditioning will not function if the fan is turned off. If air conditioning is selected with fan off, the indicator will ﬂash three times and then turn off. A slight change in engine performance may occur when the air conditioning compressor shuts off and turns on again. This is normal. The system is designed to make adjustments to help with fuel economy while still maintaining the selected temperature. The air conditioning system removes moisture from the air, so sometimes there may be a small amount of water dripping underneath the vehicle while idling or after turning off the engine. This is normal. 9(Fan): Turn the center knob on the control panel to control the fan speed. Turn the knob clockwise or counterclockwise to increase or decrease the fan speed. 9(Off): Turn the center knob to this position to turn the fan off. With the fan off, you may still experience airﬂow from the system that increases with vehicle speed depending on the mode and temperature settings. Enable recirculation mode to stop this airﬂow from occurring. The right knob on the control panel is used to direct the airﬂow inside the vehicle. Turn the knob to select one of the following modes: @(Recirculation): Press the center knob on the control panel to recirculate air inside the vehicle and prevent outside air from coming in. It can be used to prevent outside odors from entering your vehicle and cool the air inside your vehicle more quickly. Press this button to turn the recirculation mode on or off. An indicator light on the button will come on to let you know the recirculation mode is activated. 171 Recirculation is available in the bi-level, and vent modes. Recirculation is not available while in ﬂoor, ﬂoor/defog and defrost mode. If recirculation is selected in these modes, the indicator will ﬂash three times indicating it is not available in that mode. When the recirculation mode is turned on, the air conditioning will turn on automatically. H(Vent): Turn the right knob on the control panel to this mode to direct air to the instrument panel outlets. \(Bi-Level): Turn the right knob on the control panel to this mode to direct air to the instrument panel outlets, and the remaining air to the ﬂoor outlets and the defroster and side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. [(Floor): Turn the right knob on the control panel to this mode to direct air to the ﬂoor outlets, side window outlets, and defroster. Recirculation is not available in this mode. Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog or frost from your windshield and side windows. Use the defog mode to clear the windows of fog or moisture and warm the passengers. Use the defrost mode to remove fog or frost from the windshield more quickly. For best results, clear all snow and ice from the windshield before defrosting. /(Floor/Defog): Turn the right knob on the control panel to this mode to direct the air to the windshield, the side window outlets, and to the ﬂoor outlets. When you select this mode, the system runs the air conditioning system unless the outside temperature is near freezing or below. Recirculation is not available in this mode. 172 0(Defrost): Turn the right knob on the control panel to this mode to direct most of the air to the windshield, and the side window outlets. When you select this mode, the system runs the air conditioning system unless the outside temperature is near or below freezing. Recirculation is not available in this mode. Do not drive the vehicle until all the windows are clear. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window when the key is in the ignition and turned to ON. =(Rear Defogger): Press the right knob on the control panel to turn the rear window defogger on or off. First press of this button will activate the rear window defogger for 15 minutes and each subsequent activation lasts seven and one-half minutes. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by your warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. Outlet Adjustment Use the air outlets located in the center and on the side of your instrument panel to direct the airﬂow. Your vehicle has air outlets that allow you to adjust the direction and amount of airﬂow inside the vehicle. Move the louvers up or down to change the direction of the airﬂow. Use the thumbwheel under the outlets to change the direction of the airﬂow from left to right. Operation Tips (cid:127) Enable recirculation mode for maximum air conditioning performance. (cid:127) Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the ﬂow of air into your vehicle. (cid:127) Use of non-GM approved hood deﬂectors may adversely affect the performance of the system. (cid:127) Keep the path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. 173 Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle’s functions. As you will see in the details on the next few pages, some warning lights come on brieﬂy when you start the engine just to let you know they 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 when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Please follow this manual’s advice. Waiting to do repairs can be costly — and even dangerous. So please get to know your warning lights and gages. They are a big help. Your vehicle has a DIC that works along with the warning lights and gages. See Driver Information Center (DIC) on page 192 for more information. 174 Instrument Panel Cluster Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know how fast you are going, about how much fuel you have used, and many other things you will need to know to drive safely and economically. United States Automatic Transmission version shown, Canada and Manual Transmission similar 175 Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). If you operate the engine with the Notice: tachometer in the shaded warning area, your vehicle could be damaged, and the damages would not be covered by your warranty. Do not operate the engine with the tachometer in the shaded warning area. 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 or kilometers. The odometer mileage can be checked with the ignition off. Simply press the trip information stem. See “Odometer” under DIC Controls and Displays on page 192 for more information. You may wonder what happens if your vehicle needs a new odometer installed. If the new one can be set to the mileage total of the old odometer, then it must be. But if it cannot, then it is set at zero, and a label must be put on the driver’s door to show the old mileage reading when the new odometer was installed. Trip Odometer Your vehicle has a trip odometer that can tell you how far your vehicle has been driven since you last set the trip odometer to zero. See “Trip Odometer” under DIC Controls and Displays on page 192 for more information. 176 Safety Belt Reminder Light When the key is turned to ON or START, a chime will be provided for several seconds to remind people to buckle their safety belts. The driver safety belt light will also be provided and stay on for several seconds, then it will ﬂash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is buckled, neither the chime nor the light will be provided. Passenger Safety Belt Reminder Light Several seconds after the key is turned to ON or START, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 75 for more information. The passenger safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light will be repeated if the passenger remains unbuckled and the vehicle is in motion. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. 177 {CAUTION: If the airbag readiness light stays on after you start your vehicle, it means the airbag system may not be working properly. The airbags in your vehicle may not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the airbag readiness light stays on after you start your vehicle. The airbag readiness light should ﬂash for a few seconds when you turn the ignition key to ON. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Airbag Readiness Light There is an airbag readiness light on the instrument panel, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensors, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag systems, see Airbag System on page 65. This light will come on when you start your vehicle, and it will ﬂash for a few seconds. Then the light should go out. This means the system is ready. If the 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. 178 Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your instrument panel has a passenger airbag status indicator. United States Canada When the ignition key is turned to ON or START, 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. Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. 179 If, after several seconds, all status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer for service. {CAUTION: If the off indicator and the airbag readiness light ever come on together, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 178. {CAUTION: Even though the passenger sensing system is designed to turn off the passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is 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 75 for more on this, including important safety information. 180 Battery Warning Light This light will come on brieﬂy when you start the vehicle, as a check to show you it is working; then it should go out. If it stays on, or comes on while you are driving, you may have a problem with the electrical charging system. Have it checked right away. Driving while this light is on could drain your battery and result in a vehicle that may stall. See DIC Warnings and Messages on page 196 for more information. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and climate control system. Up-Shift Light (Manual Transmission) This light appears when you need to shift to the next higher gear on a manual transmission vehicle. Shifting when the indicator light is on will help you get the best fuel economy. See “Up-Shift Light” under Manual Transmission Operation on page 109 for more information. 181 Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on, there could be a brake problem. Have your brake system inspected right away. When the ignition is on, the brake system warning light will also come on when you set your parking brake. See Parking Brake on page 116 for more information. The light will stay on if your parking brake does not release fully. If it stays on after your parking brake is fully released, it means you have a brake problem. If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push, or the pedal may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 294. United States Canada This light should come on brieﬂy when you turn the ignition key to ON. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. 182 {CAUTION: Your brake system may not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to an accident. If the light is still on after you have pulled off the road and stopped carefully, have the vehicle towed for service. Anti-Lock Brake System Warning Light With the Anti-Lock Brake System (ABS), this light will come on brieﬂy when you start your engine to show it is working. Then it will turn off. This is normal. If the light stays on, or comes on when you are driving, your vehicle needs service. If the regular brake system warning light is not on, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 182. The ABS warning light should come on brieﬂy when you turn the ignition key to ON. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. 183 Traction Off Light StabiliTrak® Not Ready Light If you have the Traction Control System (TCS), this light will come on when the TCS has been turned off. If you have the StabiliTrak® system, this light will come on when the StabiliTrak® system has been turned off. This light will come on brieﬂy when the ignition is turned to ON, if it does not the system may require service. For more information on the traction off light, see Traction Control System (TCS) on page 241. This light will come on brieﬂy when the ignition is turned to ON, if it does not the system may require service. For more information, see StabiliTrak® System on page 244. 184 Engine Coolant Temperature Gage Tire Pressure Light This light should come on brieﬂy when you turn the ignition to ON. United States Canada This gage shows the engine coolant temperature. If the gage pointer is in the shaded area of the gage, the engine is too hot. It means that your engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. See Engine Overheating on page 338 for more information. This light will also come on when one or more of your tires are signiﬁcantly underinﬂated. A LOW TIRE message will also appear in the Driver Information Center (DIC), see DIC Warnings and Messages on page 196 for more information. Stop and check your tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Tires on page 367 for more information. This light will ﬂash for 60 seconds and then turn on solid if a problem is detected with the Tire Pressure Monitor system. See Tire Pressure Monitor System on page 376 for more information. 185 If you keep driving your vehicle with Notice: this light on, after awhile, your emission controls may not work as well, your fuel economy may not be as good, and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and may cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This may also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 314. Malfunction Indicator Lamp Check Engine Light Your vehicle has a computer which monitors operation of the fuel, ignition, and emission control systems. This system is called OBD II (On-Board Diagnostics-Second Generation) and is intended to assure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The check engine light comes on to indicate that there is a problem and service is required. Malfunctions often will be indicated by the system before any problem is apparent. This may prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. 186 This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: (cid:127) Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required. (cid:127) Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required. If the Light is Flashing The following may prevent more serious damage to your vehicle: (cid:127) Reducing vehicle speed (cid:127) Avoiding hard accelerations (cid:127) Avoiding steep uphill grades (cid:127) If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible If the light stops ﬂashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still ﬂashing, follow the previous steps, and see your dealer for service as soon as possible. If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. See Filling the Tank on page 318. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. 187 Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 316. Poor fuel quality will cause your engine not to run as efficiently as designed. You may notice this as stalling after start-up, stalling when you put the vehicle into gear, misﬁring, hesitation on acceleration, or stumbling on acceleration. (These conditions may go away once the engine is warmed up.) This will be detected by the system and cause the light to turn on. If you experience one or more of these conditions, change the fuel brand you use. It will require at least one full tank of the proper fuel to turn the light off. If none of the above steps have made the light turn off, your dealer can check the vehicle. Your dealer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that may have developed. 188 Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the check engine light is on or not working properly. Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your dealer can prepare the vehicle for inspection. Oil Pressure Light {CAUTION: The light will come on when you turn your key to ON or START. Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty. Always follow the maintenance schedule in this manual for changing engine oil. It goes off once you start your engine. That is a check to be sure the light works. If it does not come on, be sure to have it ﬁxed so it will be there to warn you if something goes wrong. When the light comes on and stays on, it means that oil is not ﬂowing through the engine properly. The vehicle could be low on oil and it might have some other system problem. See Engine Oil on page 323 and “OIL” under DIC Warnings and Messages on page 196 for more information. 189 Security Light Cruise Control Light This light will come on brieﬂy when you turn the key to START. The light will stay on until the engine starts. This light comes on whenever you set the cruise control. If the ignition is turned on, and the light ﬂashes, the Passlock® system has entered a tamper mode. If the vehicle fails to start, see Passlock® on page 100. If the ignition is turned on, but the engine is not running, the light should be on solid. If the light comes on continuously while driving and stays on, there may be a problem with the Passlock® system. Your vehicle will not be protected by Passlock®, and you should see your dealer. Also, see Content Theft-Deterrent on page 98 for additional information regarding the security light. The light goes out when the cruise control is turned off. See Cruise Control on page 159 for more information. Highbeam On Light This light comes on whenever the high-beam headlamps are on. See Headlamp High/Low-Beam Changer on page 157 for more information. 190 Fuel Gage Here are three things that some owners ask about. None of these indicate a problem with your fuel gage: (cid:127) At the gas station, the gas pump shuts off (cid:127) before the gage reads full. It takes a little more or less fuel to ﬁll up than the gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. United States Canada When the ignition is on, the fuel gage tells you about how much fuel you have remaining in the fuel tank. (cid:127) The gage moves a little when you turn a corner or speed up. When the fuel in the fuel tank is low, you will see a LOW FUEL message on the Driver Information Center (DIC) display. See DIC Warnings and Messages on page 196 for more information. 191 Trip Information Odometer The odometer is automatically displayed on the DIC when you start the vehicle. The odometer shows the total distance the vehicle has been driven in either miles for the United States or kilometers for Canada. Trip Odometer Press and release the reset stem until TRIP appears on the DIC display. The trip odometer shows the current distance traveled since the last reset of the trip odometer in either miles for the United States or kilometers for Canada. Press and hold the reset stem for about four seconds to reset the trip odometer. Driver Information Center (DIC) The Driver Information Center (DIC) displays information such as the trip odometer, personalization features, and warning messages. The DIC display is located on the instrument panel cluster. DIC Controls and Displays The Driver Information Center (DIC) comes on when the ignition is on. If a problem is detected, a warning message will appear on the display. Pressing and releasing the trip odometer reset stem on the DIC will acknowledge some current warnings or service messages. Some messages will only clear after the required action has been taken. The DIC has different modes which can be accessed by pressing the trip odometer reset stem on the DIC. These modes are explained in the following section. The DIC trip odometer reset stem is located on the instrument panel cluster next to the DIC display. To scroll through the available functions, press and release the reset stem. 192 Engine Oil Life System With the engine off, turn the key to ON and then press the reset stem until OIL LIFE RESET appears — alternating between OIL LIFE and RESET — on the DIC display. The CHANGE OIL message will alert you to change your oil on a schedule consistent with your driving conditions. Always reset the OIL LIFE message after an oil change. To reset the message, see Engine Oil Life System on page 326. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual.
