Your front and rear turn signal lamps will ﬂash on and off. The hazard warning ﬂasher button is located on top of the steering column. Tilt Wheel The tilt steering wheel allows you to adjust the steering wheel before you drive. You can raise it to the highest level to give your legs more room when you enter and exit the vehicle. Your hazard warning ﬂashers work no matter what position your key is in, and even if the key is not in the ignition. 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. Other Warning Devices If you carry reﬂective triangles, you can set them up at the side of the road about 300 feet (100 m) behind your vehicle. Horn Press the vehicle’s steering wheel pad to sound the horn. 3-6 The tilt lever is located on the driver’s side of the steering column under the turn signal lever. To tilt the wheel, hold the steering wheel and pull the lever. Move the steering wheel to a comfortable level, then 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) G Turn and Lane Change Signals. Turn and Lane-Change Signals on page 3-7. (cid:127) 53 Headlamp High/Low-Beam Changer. Headlamp High/Low-Beam Changer on page 3-8. Flash-to-Pass Feature. See Flash-to-Pass on page 3-8. (cid:127) N Windshield Wipers.

For information on the exterior lamps, see Exterior Lamps on page 3-14 later in this section. 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, just raise or lower the lever until the arrow starts to ﬂash. Hold it there until you complete your lane change. The lever will return by itself when you release it. 3-7 (cid:127) An arrow on the instrument panel cluster will ﬂash in the direction of the turn or lane change. 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. 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 won’t see your turn signal. If a bulb is burned out, replace it to help avoid an accident. If the arrows don’t go on at all when you signal a turn, check for burned-out bulbs and a blown fuse. See Instrument Panel Fuse Block on page 5-116 and Underhood Fuse Block on page 5-119. 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 DIC. See DIC Warnings and Messages on page 3-48. To turn the chime and message off, move the turn signal lever to the off position. 3-8 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’ll 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): For a single wiping cycle, turn the band to mist. Hold it there until the wipers start. Then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on mist longer. N(Delay): You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay. 6 (Low Speed): For steady wiping at low speed, turn the band away from you to the ﬁrst solid band past the delay settings. 1 (High Speed): For high-speed wiping, turn the band further, to the second solid band past the delay settings. 9(Off): To stop the wipers, move the band to off. Be sure to clear ice and snow from the wiper blades before using them. If they’re frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. 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. LQ (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 the preset speed. _ (Heated Washer Fluid): If your vehicle is equipped with the heated washer system, approximately ﬁve seconds after turning on your vehicle, it will be in Standby mode. Heated windshield ﬂuid can spray for three to six seconds to the windshield when the washer ﬂuid paddle is used. The heated ﬂuid is discharged by pushing the normal wash paddle in the vehicle. Standby mode is activated every time the vehicle is turned on. 3-9 To activate Automatic mode for de-icing, press the heated washer switch. The indicator light starts to ﬂash at a one second rate. Once the washer ﬂuid is heated, approximately 25 seconds, it is sprayed on the windshield. This cycle will repeat four times (approximately every six seconds) and then the unit will return to Standby mode. Pressing the heated washer ﬂuid button at any time during this cycle will stop the Automatic mode and return it to Standby. Automatic mode is recommended while the vehicle is parked. In the case of a rapidly ﬂashing light indicator on the heated washer switch, it may be necessary to wait for up to one minute for the light to stop ﬂashing, then cycle the ignition. Rear Window Wiper/Washer (SUV) If your vehicle has a rear window washer/wiper, the control knob is located on the instrument panel to the left of the steering wheel. {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. To turn the rear wiper on, turn the knob to either 1 or 2. For long delayed wiping, turn the knob to 1. For short delayed wiping, turn the knob to 2. 9(Off): To turn the wiper off, turn the knob to this symbol. =(Washer Fluid): To wash the window, press the knob with this symbol. The rear window washer uses the same ﬂuid reservoir 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. 3-10 Cruise Control 9(Off): This position turns the system off. R(On): This position activates the system. + (Resume/Accelerate): Push the lever to this symbol to make the vehicle accelerate or resume to a previously set speed. T(Set): Press this button to set the speed. 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). If you apply your brakes, the cruise control will shut off. {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause needless wheel spinning, and you could lose control. Do not use cruise control on slippery roads. 3-11 Setting Cruise Control {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. Move the cruise control switch to on. 2. Get up to the speed you want. 3. Press in the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal. The cruise symbol on the instrument panel will illuminate when the cruise control is engaged. 3-12 Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, disengages the cruise control. But you don’t need to reset it. Once you’re going about 25 mph (40 km/h) or more, you can move the cruise control switch brieﬂy from on to resume/accelerate. You’ll go right back up to your chosen speed and stay there. If you hold the switch at resume/accelerate the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don’t hold the switch at resume/accelerate. 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’ll 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 will go about 1 mph (1.6 km/h) faster. Ending Cruise Control There are four ways to turn off the cruise control: (cid:127) Step lightly on the brake pedal, (cid:127) move the cruise control switch to off, or shift the transmission to NEUTRAL (N). If road conditions cause the traction control system to activate, cruise control will turn off. See Traction Control System (TCS) on page 4-9. If the accelerator pedal is held for 60 seconds or longer, cruise control will turn off. Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased. Reducing Speed While Using Cruise Control (cid:127) Press in the button at the end of the lever until you reach the lower speed you want, then release it. To slow down in very small amounts, brieﬂy press the set button. Each time you do this, you’ll 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 will slow down to the cruise control speed you set earlier. Using Cruise Control on Hills How well your cruise control will work on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you may want to step on the accelerator pedal to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers ﬁnd this to be too much trouble and don’t use cruise control on steep hills. 3-13 (cid:127) (cid:127) (cid:127) (cid:127) Exterior Lamps The control on the driver’s side of your instrument panel operates the exterior lamps. The exterior lamp control has four positions: 9(Off): Turn the knob to this position to turn off all exterior lamps including the DRL. This control will spring back to AUTO when released. AUTO (Automatic): Turn the control to this position to put the system into automatic headlamp mode. AUTO mode, if enabled, will turn the exterior lamps, including your DRL, on and off automatically depending on how much light is available outside the vehicle. 3-14 Your automatic lights may be disabled even if the control is in the AUTO position. To enable automatic lighting, do any of the following: Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. Turn the headlamp control from the parking lamp position to AUTO. Turn the headlamp control from the headlamp position to AUTO. Turn your engine off and then on again with the headlamp control in AUTO. To disable automatic lighting, do any of the following: Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. Turn the headlamp control from AUTO to the parking lamp position. Turn the headlamp control from AUTO to the headlamp position. (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) ;(Parking Lamps): Turn the control to this position to turn on the parking lamps, together with the following: (cid:127) Sidemarker Lamps Taillamps License Plate Lamps (cid:127) Roof Marker Lamps Instrument Panel Lights 2(Headlamps): Turn the control to this position to turn on the headlamps, together with the previously listed lamps and lights. When the vehicle is turned off and the headlamps are in AUTO, the headlamps may automatically remain on for a set time. You can change this delay time using the DIC. See Driver Information Center (DIC) on page 3-45. You can switch your headlamps from low to high-beam by pushing the turn signal/multifunction lever toward the instrument panel. Headlamps on Reminder If a door is open, a reminder chime will sound when your headlamps or parking lamps are manually turned on and your key is out of the ignition. To turn off the chime, turn the headlamp switch to off or AUTO and then back on. In the AUTO mode, the headlamps turn off once the ignition is in LOCK or may remain on until the headlamp delay ends (if enabled in the DIC). Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles ﬁrst sold in Canada. The DRL system will come on when the following conditions are met: The ignition is on, the exterior lamps control is in AUTO, if enabled, the transmission is not in PARK (P), and the light sensor determines it is daytime. 3-15 (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) When the DRL are on, only your DRL lamps will be on. The taillamps, sidemarker and other lamps won’t be on. The instrument panel won’t be lit up either. 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. Automatic Headlamp System When it is dark enough outside and the headlamp switch is in AUTO, your automatic headlamp system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps, roof marker 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. Turning off the automatic headlamp system with the headlamp switch is not available for vehicles ﬁrst sold in Canada. For vehicles ﬁrst sold in Canada, you can turn off the automatic headlamp system when parked at night by applying the parking brake before starting your vehicle. The headlamps will remain off once the vehicle is started for as long as you are parked. If you release the parking brake, the lights will turn on. If the parking brake is not released before you begin to drive, the exterior lamps will turn on above 2 mph (3.2 km/h). 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 your 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 sees a change in lighting lasting longer than the delay. 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 approximately one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 3-17. 3-16 If you drive your vehicle through an Off-Road Lamps Notice: automatic car wash that does not have enough clearance for any roof-mounted accessories (such as off-road lamps or a roof basket) on your vehicle, you can damage your vehicle. To avoid damaging your vehicle in a car wash, remove any roof-mounted accessories if you can, and do not use an automatic car wash while roof-mounted accessories are on your vehicle. See Washing Your Vehicle on page 5-109 for more information. The off-road lamps, if equipped, provide auxiliary lighting when your vehicle is used off road. These lamps are not intended to be used in conjunction with, or 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. The button for the off-road lamps is located in the overhead console. To use the lamps, be sure the engine is running. Remove the covers from the lamps and press the button to turn them on. Press the button again to turn them off. An indicator light will glow near the button 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 return the lamps to the upright position and remove the covers before turning on the off-road lamps. The off-road lamps will remain on even after the ignition is turned off. The off-road lamps button must be pressed to turn them off. Loading objects onto the off-road light bar may cause damage to the light bar or off road lamps. Repairs would not be covered by your warranty. Do not load objects on the off-road light bar. Instrument Panel Brightness The thumbwheel for this feature is located next to the exterior lamps control. D (Instrument Panel Lights): Turn the thumbwheel up or down to brighten or dim the instrument panel lights and the radio display. This will only work if the headlamps or parking lamps are on. To turn on the dome lamps, with the vehicle doors closed, turn the thumbwheel all the way up. 3-17 Dome Lamps The dome lamps will come on when you open a door or the midgate, if equipped, and will turn off when all doors or midgate are closed. You can also turn the dome lamps on by turning the thumbwheel, located next to the exterior lamp control, all the way up. In this position, the dome lamps will remain on whether a door is opened or closed. Dome Lamp Override E (Dome Override): Press this button, located below the exterior lamp control, to turn dome lamps off even while a door is opened. To return the lamps to automatic operation, press the button again and it will return to the out position. In this position, the dome lamps will come on when you open a door. Entry/Exit Lighting Your vehicle is equipped with an illuminated entry/exit feature. When a door is opened or the key is removed from the ignition, the dome lamps will come on if the dome override button is in the out position. Reading Lamps Your vehicle has reading lamps located in the overhead console. Press the button located next to the lamp to turn it on. The lamps can be adjusted to point in the direction you want. Press the button again to turn the lamp off. These lamps will also come on with the dome lamps. Battery Run-Down Protection This feature shuts off the dome lamps if they are left on for more than 10 minutes when the ignition is in LOCK. This will keep your battery from running down. Rear Vision Camera Your vehicle may be equipped with a rear vision camera system. Read this entire section before using the camera system. The rear vision camera system is designed to help the driver when backing up by displaying a view of the area behind the vehicle. When the driver shifts the vehicle into REVERSE (R), the video screen will automatically slide out from the rear view mirror. Once the driver shifts out of REVERSE (R), the video screen will slide back into the rear view mirror after a delay. 3-18 To turn off the rear vision camera system, do the following: 1. Place the vehicle shift lever in (P) PARK. 2. Turn the ignition key to the ACCESSORY position. 3. Press the right mirror button brieﬂy; the right green light indicator will turn off.

To resume normal operation, press the right button momentarily while the rear camera screen is out or wait 30 seconds for screen to slide back into the mirror. {CAUTION: Do not back the vehicle while only looking at the rear vision camera screen. The distances between objects and surfaces will differ from actual distances. The camera system does not display objects that are below the bumper, underneath the vehicle, or objects out of the camera’s ﬁeld of view. The rear vision camera is not intended for use during longer backing maneuvers or backing into potential crossing traffic. Crossing traffic may be approaching outside of the camera’s ﬁeld of view. If the driver backs up the vehicle while only looking at the screen, they may hit a pedestrian, bicyclist, child, pet, or other object resulting in injury or death. The driver should always check behind and around the vehicle when backing up just as they would if they did not have the rear vision camera. 3-19 Area Displayed On Screen The image is provided by the camera located on the rear bumper. The camera uses a special lens. The distance of the image that appears on the screen differs from the actual distance. The area displayed by the camera is limited. The camera does not display objects which are close to either corner of the bumper or under the bumper. The area displayed on the screen may vary according to vehicle orientation or road conditions. The following illustration shows the ﬁeld of view that the camera provides. 3-20 When the System Does Not Seem To Work Properly The rear vision camera system may not work properly or display a clear image in the following situations: In the dark. (cid:127) When the sun or the beam of headlights is shining directly into the camera lens. If ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. If the back of the vehicle is in an accident, the position and mounting angle of the camera may change or the camera may be affected.

Notice: items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your vehicle. Never put ﬂammable items in the ashtray. To remove the ashtray, pull it out from the console. To reinstall the ashtray, slide it back to the original position. To use the cigarette lighter, if equipped, push 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. 3-22 Turn the knob counterclockwise or clockwise to lower or increase the cabin temperature. The display will show the temperature setting decreasing or increasing and an arrow pointing to the passenger will be displayed under and to the right of the temperature setting. The passenger’s temperature setting can be set to match the driver’s temperature setting by pressing and holding the AUTO button for four seconds. Both the driver and passenger arrows will be displayed. Automatic Operation AUTO (Automatic): When automatic operation is active the system will control the inside temperature, the air delivery, and the fan speed. Driver’s Side Temperature Knob The driver’s side knob is used to adjust the temperature of the air coming through the system on the driver’s side. The temperature can be adjusted even if the system is turned off. This is possible since outside air will always ﬂow through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section. Turn the knob counterclockwise or clockwise to lower or increase the cabin temperature. The display will show the temperature setting decreasing or increasing and an arrow pointing to the driver will be displayed under and to the left of the temperature setting. Passenger’s Side Temperature Knob The passenger’s side knob can be used to change the temperature of the air coming through the system on the passenger’s side of the vehicle. The temperature can be adjusted even if the system is turned off. This is possible since outside air will always ﬂow through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section. 3-23 Use the steps below to place the entire system in automatic mode: 1. Press the AUTO button. When AUTO is selected, the display will change to show the current driver’s set temperature, delivery mode and fan speed. Press the AUTO button again within ﬁve seconds to display the passenger’s set temperature. If the driver and passenger’s temperature settings are not the same, the opposite side temperature setting will be displayed for an additional ﬁve seconds. To make the passenger’s temperature the same as the driver’s press and hold the AUTO button for about four seconds. When auto is selected, the air conditioning operation and air inlet will be automatically controlled. The air conditioning compressor will run when the outside temperature is over about 40°F (4°C). The air inlet will normally be set to outside air. If it’s hot outside, the air inlet may automatically switch to recirculate inside air to help quickly cool down your vehicle. The light on the button will illuminate in recirculation. 2. Set the driver’s and passenger’s temperature. To ﬁnd your comfort setting, start with a 74°F (23°C) temperature setting and allow about 20 minutes for the system to regulate. Turn the driver’s or 3-24 passenger’s side temperature knob to adjust the temperature setting as necessary. If you choose the temperature setting of 60°F (15°C) the system will remain at the maximum cooling setting. If you choose the temperature setting of 90°F (32°C) the system will remain 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 sensor located on the top of the instrument panel near the windshield. This sensor regulates air temperature based on sun load, and also turns on your headlamps. To avoid blowing cold air in cold weather, the system will delay turning on the fan until warm air is available. The length of delay depends on the engine coolant temperature. Pressing the fan switch will override this delay and change the fan to a selected speed. 9(Off): Press this button to turn off the entire climate control system. Outside air will still enter the vehicle, and will be directed to the ﬂoor. This direction can be changed by pressing the mode button. The temperature can also be adjusted using either temperature knob. Press the up or down arrows on the fan switch, the defrost button, the AUTO button, or the air conditioning button to turn the system on when it is off. Manual Operation You may manually adjust the air delivery mode or fan speed. w9x (Fan): The switch with the fan symbol allows you to manually adjust the fan speed. Press the up arrow to increase fan speed and the down arrow to decrease fan speed. Pressing this button when the system is off will turn the system on. C (Mode): Press this button to manually change the direction of the airﬂow in your vehicle; repeatedly press the button until the desired mode appears on the display. If you press the mode button to select an air delivery mode, the display will change to show you the selected air mode delivery. The display will then show the current status of the system. When the system is turned off, the display will go blank after displaying the current status of the system. H (Panel): This setting will deliver air to the instrument panel outlets. )(Bi-Level): This setting will deliver warmer air to the ﬂoor and cooler air to the instrument panel outlets. 6 (Floor): This setting will deliver air to the ﬂoor outlets. - (Defog): See “Defogging and Defrosting” later in this section. @(Recirculation): Press this button to limit the amount of outside air entering your vehicle. The light on the recirculation button will glow. This is helpful when you are trying to limit odors entering your vehicle and for maximum air conditioning performance in hot weather. Press this button again to allow outside air to enter the vehicle. The light on the recirculation button will go off. Pressing this button also cancels the auto recirculation feature. To resume the auto recirculation function, press the AUTO button. Each time the vehicle is started, the system will revert to the auto recirculation function. If you select recirculation while in defrost, defog or ﬂoor, the light in the button will ﬂash and then go out to let you know that this is not allowed. This is normal and helps to prevent fogging. When the weather is cool or damp, operating the system in recirculation for extended periods of time may cause fogging of the vehicle’s windows. To clear the fog, select either defog or front defrost. You may also notice that the A/C compressor will run while in recirculation mode. This is normal and helps to prevent fogging. 3-25 9(Off): Press this button to turn off the entire climate control system. Outside air will still enter the vehicle, and will be directed to the ﬂoor. This direction can be changed by pressing the mode button. The temperature can also be adjusted using either temperature knob. Press the up or down arrows on the fan switch, the defrost button, the AUTO button, or the air conditioning button to turn the system on when it is off. Display If you press the MODE button to select an air delivery mode, the display will change to show you the selected air delivery mode. After ten seconds, the display will change to show the driver temperature setting and the selected mode. If you press the up or down arrows on the fan switch, the display will change to show the selected fan speed. After ten seconds, the display will change to show the driver temperature setting and the selected mode. Whenever you press AUTO, the display will change to show the following: the current driver’s set temperature and an arrow for ﬁve seconds, the current passenger’s set temperature setting and an arrow for ﬁve seconds and the automatic air delivery mode and fan speed. 3-26 If the driver’s and passenger’s temperature settings are the same when AUTO is pressed, the temperature setting and both arrows will be displayed for ﬁve seconds along with the automatic air delivery mode and fan speed. After the ﬁve second update, the display will change to show the temperature setting, both arrows and AUTO. Air Conditioning #(Air Conditioning): Press this button to turn the air conditioning (A/C) compressor on and off. The snowﬂake symbol will appear on the display when the A/C is on. Pressing this button when the outside temperature is too cool for air conditioning to be effective will make the snowﬂake symbol ﬂash three times and then turn off to let you know that 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 snowﬂake symbol will turn off to let you know that the air conditioning mode has been canceled. When air conditioning is selected or in AUTO mode, the system will run the air conditioning automatically to cool and dehumidify the air entering the vehicle. If you select A/C off while in front defrost, defog or recirculation, the A/C snowﬂake symbol will turn off, but the A/C compressor will still run to help prevent fogging. (cid:127) (cid:127) (cid:127) On hot days, open the windows long enough to let hot inside air escape. This reduces the time it takes for your vehicle to cool down. Then keep your windows closed for the air conditioner to work its best. On cool, but sunny days while using manual operation of the automatic system, use bi-level to deliver warm air to the ﬂoor and cooler air to the instrument panel outlets. To warm or cool the air delivered, turn the temperature knob to the desired setting. In AUTO mode the system will cool and dehumidify the air inside the vehicle. Also while in AUTO mode, the system will maximize its performance by using recirculation as necessary. Heating On cold days when using manual operation of the automatic system, choose ﬂoor mode to deliver air to the ﬂoor outlets. To warm or cool the air delivered, turn the temperature knob to the desired setting. If you want to use the automatic mode, press AUTO and adjust the temperature by turning the temperature knob. The heater works best if you keep the windows closed while using it. Defogging and Defrosting You can use either defog or front defrost to clear fog or frost from your windshield. Use the defog mode to clear the windows of fog or moisture. Use the front defrost button to defrost the front windshield. -(Defog): Use this setting to clear the windows of fog or moisture. Press the mode button to select this setting. This setting will deliver air to the ﬂoor and windshield outlets. 0 (Front Defrost): Press the front defrost button to defrost the windshield. The system will automatically control the fan speed if you select defrost from AUTO mode. If the outside temperature is 40°F (4°C) or warmer, your air conditioning compressor will automatically run to help dehumidify the air and dry the windshield. Rear Window Defogger If your vehicle has this feature, the lines you see on the rear window warm the glass. The rear window defogger uses a warming grid to remove fog from the rear window. <(Rear): Press this button to turn the rear window defogger on or off. An indicator light in the button will come on to let you know that the rear window defogger is activated. 3-27 The rear window defogger will turn off about 10 minutes after the button is pressed. If you need additional warming time, press the button again. If your vehicle is equipped with heated mirrors this button will activate them. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Outlet Adjustment Your vehicle has air outlets that allow you to adjust the direction and amount of airﬂow inside the vehicle. Push the knob in the center of the outlet up, down, left or right to move the outlet in the direction you would like. Turn the knob in the center of the outlet so the louvers open or close to increase or decrease airﬂow. Operation Tips (cid:127) Keep the hood and front air inlets free of ice, snow, or any other obstruction (such as leaves). The heater and defroster will work far better, reducing the chance of fogging the inside of your windows. (cid:127) Keep the air path under the front seats clear of objects. This helps air to circulate throughout your vehicle. (cid:127) Adding outside equipment to the front of your vehicle, such as hood-air deﬂectors, etc., may affect the performance of the heating and air conditioning system. Check with your dealer before adding equipment to the outside of your vehicle. 3-28 Warning Lights, Gages, and Indicators This part describes the warning lights and gages 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 also has a Driver Information Center (DIC) that works along with warning lights and gages. See DIC Warnings and Messages on page 3-48. 3-29 Instrument Panel Cluster United States version shown, Canada 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. 3-30 Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your vehicle’s odometer works together with the driver information center. You can set a Trip A and Trip B odometer. See “Trip Information” under DIC Operation and Displays on page 3-45. The odometer mileage can be checked without the vehicle running. Simply press the trip stem on the instrument panel cluster. If your vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer. 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 trip odometer display, 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. Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). Safety Belt Reminder Light When the key is turned to RUN 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. 3-31 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 system, see Airbag System on page 1-58. 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. {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 RUN. If the light doesn’t come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Airbag Off Light 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 1-65 for more on this, including important safety information. 3-32 {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 1-65, for more on this, including important safety information. 3-33 United States Canada {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. See Airbag Off Switch on page 1-65 for more on this, including important safety information. Charging System Light Voltmeter Gage The charging system light will come on brieﬂy when you turn on the ignition, but the engine is not running, as a check to show you it is working. When your engine is not running, but the ignition is in RUN, this gage shows your battery’s state of charge in DC volts. It should go out once the engine is running. If it stays on, or comes on while you are driving, you may have a problem with the charging system. It could indicate that you have problems with a generator drive belt, or another electrical problem. Have it checked right away. Driving while this light is on could drain your battery. When this light comes on the DIC will also display the battery not charging message. See DIC Warnings and Messages on page 3-48. If you must drive a short distance with the light on, be certain to turn off all your accessories, such as the radio and air conditioner. When the engine is running, the gage shows the condition of the charging system. Readings between the low and high warning zones indicate the normal operating range. Readings in the low warning zone may occur when a large number of electrical accessories are operating in the vehicle and the engine is left at an idle 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. 3-34 You can only drive for a short time with the reading in either warning zone. If you must drive, turn off all unnecessary accessories. Readings in either warning zone 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 ﬂash when you set the parking brake. The light will ﬂash if the parking brake does not release fully. If you try to drive with the parking brake engaged, a chime will sound when the vehicle speed is greater than 3 mph (5 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 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’s a 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 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 4-59. {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. United States Canada 3-35 Anti-Lock Brake System Warning Light Traction Off Light The traction off light will come on when a traction control system or anti-lock brake system problem has been detected. The vehicle may need service. When this light is on, the system will not limit wheel spin. Adjust your driving accordingly. See Traction Control System (TCS) on page 4-9. If the Traction Control System (TCS) detects that the vehicle’s brake’s are overheating, the TCS will shut off and the traction off light will come on. When the brakes cool off, the TCS will turn back on automatically and the traction off light will go out. With the anti-lock brake system, this light will come on when you start your engine and may stay on for several seconds. That’s normal. If the light doesn’t come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If the light stays on, or comes on when you’re driving, your vehicle needs service. You will also hear a chime sound when the light is on steady. If the regular brake system warning light isn’t on, you still have brakes, but you don’t have anti-lock brakes. If the regular brake system warning light is also on you don’t have anti-lock brakes and there’s a problem with your regular brakes. In addition to both lights, you will also hear a chime sound on the ﬁrst occurrence of a problem and each time the vehicle is shut off and then restarted. See Brake System Warning Light on page 3-35. 3-36 Engine Coolant Temperature Gage Transmission Temperature Gage United States Canada 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 approach the 250°F (122°C) mark. 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 5-27. Your vehicle is equipped with a transmission temperature gage. When your ignition is on, the gage shows the temperature of the transmission ﬂuid. The normal operating range is from 180°F (82°C) to about 200°F (93°C). At approximately 265°F (130°C), the DIC will display a TRANSMISSION HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission ﬂuid temperature falls below 260°F (127°C). 3-37 If the transmission ﬂuid reaches temperatures of approximately 275°F (135°C) or greater, the DIC will display a TRANS HOT IDLE ENGINE warning message and a chime will sound. Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in PARK (P) and allow the engine to idle until the transmission temperature falls below 260°F (127°C). If the transmission continues to operate above 265°F (130°C), please contact your nearest dealer or the GM Roadside Assistance Center. See Driver Information Center (DIC) on page 3-45 for further information. Notice: transmission temperature gage above normal operating range, you can damage the transmission. This could lead to costly repairs that would not be covered by your warranty. Do not drive your vehicle while the transmission temperature gage reading is above normal. See your dealer for service. If you drive your vehicle with the The following situations can cause the transmission to operate at higher temperatures: Towing a trailer, hot outside air temperatures, hauling a large or heavy load, low transmission ﬂuid level, high transmission ﬂuid level, restricted air ﬂow to the radiator. A temporary solution to hotter transmission operating temperatures may be to let the transmission cool down. If the transmission is operated at higher temperatures on a frequent basis, see Scheduled Maintenance on page 6-4 for the proper transmission maintenance intervals. 3-38 (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) Malfunction Indicator Lamp Check Engine Light Your vehicle is equipped with 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. Notice: 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. If you keep driving your vehicle with this 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 5-3. 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: 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. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required. 3-39 (cid:127) (cid:127) 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 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 5-8. The diagnostic system can determine if the fuel cap has 3-40 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. Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 5-5. 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. (cid:127) 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 GM dealer can prepare the vehicle for inspection. Oil Pressure Gage United States Canada The oil pressure gage shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals). Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. 3-41 This light will come on brieﬂy when you turn the key toward START. The light will stay on until the engine starts. If the light ﬂashes, the Passlock® system has entered a tamper mode. If the vehicle fails to start, see Passlock® on page 2-23. 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 2-21 for additional information regarding the security light. A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check your oil as soon as possible. See Engine Oil on page 5-14. Security Light {CAUTION: Do not keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches ﬁre. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. Notice: Lack of proper engine oil maintenance may damage the engine. The repairs would not be covered by your warranty.

The gage will ﬁrst indicate empty before you are out of fuel, and you should get more fuel as soon as possible. 3-44 Here are some situations you may experience with your fuel gage. None of these indicate a problem with the fuel gage. (cid:127) At the gas station, the fuel pump shuts off before the gage reads full. It takes a little more or less fuel to ﬁll up than the fuel gage indicated. For example, the gage may have indicated the tank was half full, but it actually took a little more or less than half the tank’s capacity to ﬁll the tank. The gage goes back to empty when you turn off the ignition. Low Fuel Warning Light The light next to the fuel gage will come on brieﬂy when you are starting the engine. This light comes on and a FUEL LEVEL LOW message will appear on the Driver Information Center when the fuel tank is low on fuel. To turn it off, add fuel to the fuel tank. See Fuel on page 5-5 and DIC Warnings and Messages on page 3-48 for more information.
