Horn To sound the horn, press the horn symbols on the steering wheel pad. The hazard warning ﬂasher button is located on top of the steering column. Tilt Wheel The tilt lever is on the outboard side of the steering column, under the turn signal lever. Press the button to make the front and rear turn signal lamps ﬂash on and off. Press the button again to turn the ﬂashers off. The hazard warning ﬂashers work no matter what ignition position the key is in, and even if the key is not in the ignition. When the hazard warning ﬂashers are on, your vehicle’s turn signals will not work. Other Warning Devices If you carry reﬂective triangles, you can set them up at the side of the road about 300 feet (100 m) behind your vehicle. 3-6 Do not adjust the steering wheel while driving. Hold the steering wheel and pull the lever toward you to change the position, then release the lever to lock. 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 (cid:127) 23 Headlamp High/Low-Beam Changer Flash-to-Pass Feature (cid:127) N Windshield Wipers (cid:127) J Windshield Washer (cid:127) I Cruise Control Turn and Lane-Change Signals The turn signal has two upward and two downward positions. To signal a turn, move the lever all the way up or down. When the turn is ﬁnished, the lever returns automatically. An arrow on the instrument panel cluster ﬂashes in the direction of the turn or lane change. To signal a lane change, raise or lower the lever until the arrow starts to ﬂash. Hold it there until your lane change is completed. The lever returns by itself when released. If the arrows ﬂash more quickly than normal, a signal bulb could be burned out. Replace the bulb. If the arrows do not go on at all when you signal a turn, check the fuse. See Fuses and Circuit Breakers on page 5-110 and check for burned-out bulbs. If you have a trailer towing option with added wiring for the trailer lamps, a turn signal ﬂasher is used. With this ﬂasher installed, the signal indicator ﬂashes even if a turn signal bulb is burned out. Check the front and rear turn signal lamps regularly to make sure they are working. 3-7 (cid:127) Turn Signal On Chime A chime sounds if the turn signal has been on 3/4 of a mile (1.2 km). Move the turn signal lever to off. Headlamp High/Low-Beam Changer To change the headlamps from low to high beam, push the lever toward the instrument panel. To return to low-beam headlamps, pull the multifunction lever toward you. Then release it. When the high beams are on, this indicator light on the instrument panel cluster will also be on. Flash-to-Pass This feature lets you use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are in the automatic position. To use it, pull the turn signal lever toward you, then release it. If the headlamps are in the automatic position or on low beam, the high-beam headlamps turn on. They will stay on as long as you hold the lever toward you. The high-beam indicator on the instrument panel cluster comes on. Release the lever to return to normal operation. 3-8 Windshield Wipers Windshield Washer L(Windshield Washer): To spray washer ﬂuid on the windshield, press the windshield washer 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. 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. If more wipes are needed, hold the band on mist longer. 9(Off): Move the band to off, to stop the wipers. N(Windshield Wipers): Turn the band to control the windshield wipers. The wiper speed can be set 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. For steady wiping at low speed, turn the band away from you to the ﬁrst solid band past the delay settings. For high-speed wiping, turn the band further, to the second solid band past the delay settings. 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 are frozen to the windshield, carefully loosen or thaw them. If the blades do become worn or damaged, get new blades or blade inserts. 3-9 Rear Window Wiper/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. To turn the rear wiper on, turn the control to either 1, 2, or 3. For delayed wiping, turn the control to 1 or 2. For steady wiping, turn the control to 3. To turn the wiper off, turn the control to 0. To wash the rear window, press the washer symbol located in the center of the control. The rear window washer uses the ﬂuid from the same reservoir as the windshield washer. However, the rear window washer runs out of ﬂuid before the windshield washer. If you can wash your windshield but not your rear window, check the ﬂuid level. The rear window/washer control is located to the right of the steering wheel on the instrument panel. 3-10 Headlamp Washer Cruise Control Your vehicle may have a headlamp washer system. The button to operate this feature is located on the instrument panel and functions separately from your other washer systems. Your vehicle has cruise control. The controls are located on the end of the turn signal/multifunction lever. To wash your headlamps, press the headlamp washer button brieﬂy and release to activate the system. R (On): Move the switch to this position to turn the cruise control system on. S (Resume/Accelerate): Move the switch to this position to resume a set speed or to accelerate. T (Set): Press this button, located at the end of the lever, to set a speed. 9(Off): Move the switch to this position to turn the cruise control system off and cancel memory of a set speed. 3-11 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 the brakes, the cruise control shuts 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 excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. {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. Setting Cruise Control 1. Move the cruise control switch to on. 2. Get up to the speed you want. 3. Press the set button at the end of the lever and release it. 4. Take your foot off the accelerator pedal. The accelerator pedal will not go down. Some vehicles have a cruise light on the instrument panel cluster that will come on when the cruise control is engaged. 3-12 Resuming a Set Speed Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, shuts off 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. You will go right back up to the previously chosen speed and stay there. If you hold the switch at resume/accelerate, the vehicle keeps going faster until you release the switch or apply the brakes. So unless you want to go faster, do not 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 button at the end of the lever, then release the button and the accelerator pedal. You will now cruise at the higher speed. (cid:127) Move the cruise switch from on to resume/ accelerate. Hold it there until you get up to the desired speed 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. Reducing Speed While Using Cruise Control Press in the set button at the end of the lever until you reach the desired speed, then release it. 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 will slow down to the cruise control speed set earlier. Using Cruise Control on Hills How well your cruise control works on hills depends upon your speed, load and the steepness of the hills. When going up steep hills, you 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 do not use cruise control on steep hills. 3-13 Ending Cruise Control There are three ways to turn off the cruise control: (cid:127) Step lightly on the brake pedal. (cid:127) Move the cruise switch to off, or (cid:127) Shift the transmission to NEUTRAL (N). Erasing Speed Memory When you turn off the cruise control or the ignition, the cruise control set speed memory is erased. Headlamps The exterior lamps knob is located on your instrument panel to the left of the steering wheel. c (Off): Turn the knob to this symbol and release it to turn off the Daytime Running Lamps (DRL) and the Automatic Headlamps (AHS). An indicator illuminates when the position is selected. This position is not available for vehicles ﬁrst sold in Canada. ? (Automatic DRL/AHS): Turn the knob to this symbol to put the system into automatic headlamp mode. ; (Parking Lamps): Turn the knob to this symbol to turn on the parking lamps, as well as the following: (cid:127) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights 2 (Headlamps): Turn the knob to this symbol to turn on the headlamps, as well as the following: (cid:127) Parking Lamps (cid:127) Sidemarker Lamps Taillamps License Plate Lamps Instrument Panel Lights 3-14 (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) (cid:127) Headlamps on Reminder A reminder tone sounds when the headlamps or parking lamps are manually turned on, if the driver’s door is open and the ignition is in LOCK or ACC. To turn the tone off, turn the knob all the way counterclockwise. In the automatic mode, the headlamps turn off once the ignition key is in LOCK. 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 DRL are required on all vehicles ﬁrst sold in Canada. The DRL system makes the headlamps come on at reduced brightness when the following conditions are met: The ignition is on. The exterior lamps knob is in automatic headlamp mode. The light sensor detects daytime light. The transmission is not in PARK (P). When the DRL are on, only the headlamps will be on. The taillamps, sidemarker and other lamps will not be on. The instrument panel will not be lit up either. When it begins to get dark, the headlamps automatically switch from DRL to the regular headlamps. Automatic Headlamp System When it is dark enough outside, the Automatic Headlamp System turns on the headlamps when the vehicle is started and after the transaxle has been shifted out of the PARK (P) position. The headlamps, taillamps, sidemarker, and parking lamps will come on. The instrument panel lights and radio lights will also turn on at normal brightness. Once on, the system remains on during these conditions even if the vehicle is shifted back into PARK (P). The vehicle has a light sensor on the top of the instrument panel. Make sure it is not covered or the system may come on whenever the ignition is on and the vehicle is shifted out of the PARK (P) position. The system could also turn on the lamps when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. 3-15 (cid:127) (cid:127) (cid:127) (cid:127) 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 are only 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 comes on after the transmission is shifted out of PARK (P). 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 might not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. If the vehicle is running and the automatic headlamp system is already on, it can be turned off by turning and releasing the headlamp control at the off position. The automatic headlamp system stays off until you turn and release the headlamp control at the off position again. See Headlamps on page 3-14. Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The ignition must be in RUN for the fog lamps to work. The fog lamp button is located on the instrument panel to the right of the exterior lamps knob. Press the button to turn the fog lamps on. Press the button again to turn them off. A light glows near the button while the fog lamps are on. Fog lamps turn off whenever the high-beam headlamps are on. Some localities have laws that require the headlamps to be on along with the fog lamps. 3-16 Instrument Panel Brightness Dome Lamp Override Press the knob located next to the exterior lamps knob to extend it. The dome override button is located below the exterior lamps knob. Turn the knob to adjust the instrument panel lights. Turn the knob all the way up to turn on the interior lamps. Press the knob back into its stored position when you are not using it. Dome Lamps The dome lamps will come on when you open a door unless the dome lamp override is pressed in. To turn the dome lamps off, press the button. The dome lamps will remain off when a door is open. This will override the illuminated entry feature unless you use the Remote Keyless Entry (RKE) transmitter to unlock the vehicle. To return the lamps to automatic operation, press the button again. The dome lamps come on when a door is opened. 3-17 Entry Lighting The vehicle has entry lighting. When any door is opened, the dome lamps come on as long as the dome override lamp override button is not pressed in. When all the doors are closed, the lamps stay on for a short period of time and then turn off automatically. If you use the Remote Keyless Entry (RKE) transmitter to unlock the vehicle, the interior lamps come on for a short time whether or not the dome lamp override is on. Exit Lighting With exit lighting, the interior lamps come on when you remove the key from the ignition. If the dome override is off, these lamps stay on for a short period of time and then go out. Reading Lamps The reading lamps are located in the front console. Press the lens on the lamps to turn the reading lamps on or off. Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery’s temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery’s state of charge is low, the voltage is raised slightly to quickly put the charge back in. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following loads are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. 3-18 EPM works to prevent excessive discharge of the battery. It does this by balancing the generator’s output and the vehicle’s electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as Battery Saver Active or Service Battery Charging System. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 3-53. Battery Run-Down Protection This feature shuts off the dome, courtesy, and vanity lamps if they are left on for more than 20 minutes when the ignition is off. This will keep the battery from running down. If the battery run-down protection shuts off the interior lamps, it may be necessary to do one of the following to return to normal operation: (cid:127) Shut off all lamps and close all doors. Turn the ignition key to RUN. This feature will also turn off the parking lamps and headlamps under most circumstances, if they are left on. If you would like to turn them back on, turn the exterior lamps knob. 3-19 (cid:127) Accessory Power Outlet(s) With the accessory power outlets, you can plug in auxiliary electrical equipment such as a cellular telephone or CB radio. Your vehicle has three accessory power outlets. There are two outlets located below the climate controls and one outlet is on the rear of the center ﬂoor console. Remove the cover from the outlet to use the outlet. Be sure to put the cover back on when not using the accessory power outlet. Certain electrical accessories may not be compatible with the accessory power outlet and could result in blown vehicle or adaptor fuses. If you experience a problem, see your dealer for additional information on the accessory power outlets. Notice: Adding any electrical equipment to your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. 3-20 Improper use of the power outlet can cause Notice: damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Ashtray(s) and Cigarette Lighter Your vehicle may have this feature. The ashtray is removable and ﬁts into the front cupholder. Notice: If you put papers, pins, or other 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 remove the ashtray, pull the covered bin out of the cupholder. To use the lighter, press it in all the way, and let go. When it is 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. Do not use equipment exceeding maximum amperage rating of 20 amperes. Climate Controls Dual Climate Control System With this system you can control the heating, cooling, and ventilation for your vehicle. 9(Fan): Turn the left knob clockwise or counterclockwise to increase or decrease the fan speed. If the knob is in off mode, outside air still enters the vehicle, and is directed based on the position of the mode knob. The temperature can still be adjusted using the temperature knob. Turn the right knob clockwise or counterclockwise to direct the airﬂow inside of your vehicle. To change the current mode, select one of the following: H(Vent): This mode directs air to the instrument panel outlets. )(Bi-Level): This mode directs about half of the air to the instrument panel outlets; then directs most of the remaining air to the ﬂoor outlets. A little air is directed toward the windshield and the side window outlets. Cooler air is directed to the upper vents and warmer air to the ﬂoor outlets. 6(Floor): This mode directs most of the air to the ﬂoor outlets with a little air directed to the windshield and the side window outlets. The recirculation button cannot be selected while in ﬂoor mode. @ (Recirculation): Recirculation mode is used to recirculate the air inside of your vehicle. When this button is pressed, an indicator light in the button will come on to let you know that it is active. Use this mode to help prevent outside odors and/or dust from entering your vehicle or to help cool the air inside of your vehicle more quickly. The air conditioning compressor will also come on when this mode is activated. While in recirculation mode, the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase fan speed. Defog and defrost modes are described later in this section. 3-21 Driver’s Side Temperature Lever: The lever on the left side of the climate control panel is used to raise or lower the temperature on the driver’s side of the vehicle. Slide the lever up or down to adjust the temperature. Passenger’s Side Temperature Lever: The lever on the right side of the climate control panel is used to raise or lower the temperature on the passenger’s side of the vehicle. Slide the lever up or down to adjust the temperature. This lever also adjusts the temperature to the rear seat outlets. When the temperature outside is 0°F (−18°C) or lower, use the engine coolant heater, if the vehicle has one, to provide warmer air, faster to your vehicle. #(Air Conditioning): Press this button to turn the air-conditioning system on or off. When the button is pressed, an indicator light will come on and the system will begin to cool and dehumidify the air inside of the vehicle. You may notice a slight change in engine performance when the air conditioning compressor shuts off and turns on again. This is normal. 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 choose from to clear fog or frost from your windshield. 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. Turn the right knob clockwise or counterclockwise to select one of the following modes: -(Defog): This mode directs the air to the ﬂoor outlets, windshield and side window outlets. The recirculation button cannot be selected while in defog mode. 1(Defrost): This mode directs most of the air to the windshield and the side window outlets, with only a little air directed to the ﬂoor outlets. The air conditioning compressor may run to dehumidify the air to prevent window fogging. The recirculation button cannot be selected while in defrost mode. Do not drive the vehicle until all the windows are clear. 3-22 Rear Window Defogger If your vehicle has the rear window defogger a warming grid is used to remove fog on 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 active. The rear window defogger will automatically turn off approximately ten minutes after the button is pressed. If your vehicle has heated mirrors, this button will activate them. 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. Dual Automatic Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. When your vehicle is ﬁrst started and the climate control system is on, or if the climate control system has been turned on, the display will show the driver’s temperature setting for ﬁve seconds. Then it will show the outside temperature. 3-23 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. Press the AUTO button, the mode button, the fan arrows, or either temperature knob to turn the system on. C(Mode): Press this button to manually select the air delivery mode to the ﬂoor, instrument panel, or windshield outlets. The system will stay in the selected mode until the mode button is pressed again or the AUTO button is pressed. Driver’s Side Temperature Knob: Turn this knob clockwise or counterclockwise to raise or lower the temperature on the driver’s side of the vehicle. The display will show the temperature setting decreasing or increasing and an arrow pointing toward the driver. This knob can also adjust the passenger’s side temperature setting if the two are linked. Passenger’s Side Temperature Knob: Turn this knob clockwise or counterclockwise to manually raise or lower the temperature on the passenger’s side of the vehicle. The display will show the temperature setting decreasing or increasing and an arrow pointing toward the passenger. The passenger’s temperature setting can be set to match and link to the driver’s temperature setting by pressing and holding the AUTO button for three seconds. When adjusting the driver’s side temperature setting, the passenger’s side temperature setting will follow and both arrows will appear on the display. The passenger’s side temperature setting also resets and relinks to the driver’s side temperature setting if the vehicle has been off for more than three hours. Outside Air Temperature Display A new outside temperature reading will be displayed if the vehicle has been off for more than three hours. If the vehicle has been off for less than three hours, the old temperature reading may be displayed because underhood heat is affecting the true outside temperature. Underhood heat can also affect the outside temperature while the engine is running. It may also take several minutes of driving before the display updates to the actual outside temperature. 3-24 Automatic Operation AUTO (Automatic): When automatic operation is active, the system will control the inside temperature, the air delivery mode, and the fan speed. Use the steps below to place the entire system in automatic mode: 1. Press the AUTO button. When AUTO is selected, the air conditioning operation and air outlet mode will be automatically controlled. The air conditioning compressor will run continuously when the outside temperature is over approximately 40°F (4°C). The air inlet will normally be set to outside air. If it’s hot outside, the air inlet will automatically switch to recirculate inside air to help quickly cool down your vehicle. 2. Set the driver’s and passenger’s temperature. To ﬁnd your comfort setting, start with a 72°F (22°C) temperature setting and allow about 20 minutes for the system to adjust. Turn the driver’s or 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 may not cause the vehicle to heat or cool any faster. Manual Operation To change the current setting, select one of the following: w9x(Fan): This button allows you to manually adjust the fan speed. Press the up arrow to increase fan speed and the down arrow to decrease fan speed. The display will change to show you the selected fan speed and the driver’s side temperature setting for ﬁve seconds. C (Mode): Press this button to manually change the direction of the airﬂow in your vehicle. Keep pressing the button until the desired mode appears on the display. The display will change to show you the selected air delivery mode and the driver’s temperature setting for ﬁve seconds. H (Vent): This mode directs air to the instrument panel outlets. )(Bi-Level): This mode directs approximately half of the air to the instrument panel outlets, then directs the remaining air to the ﬂoor outlets. A little air is directed toward the windshield and the side window outlets. Cooler air is directed to the upper outlets and warmer air to the ﬂoor outlets. 3-25 6(Floor): This mode directs most of the air to the ﬂoor outlets. Some air also comes out of the defroster and side window outlets. The recirculation button cannot be selected in ﬂoor mode. @(Recirculation): Press this button to turn recirculation mode on or off. When this button is pressed, an indicator light in the button will also come on to let you know that it is activated. Recirculation mode is used to recirculate the air inside of your vehicle. Use this mode to help prevent outside odors and/or dust from entering your vehicle or to help cool the air inside of your vehicle more quickly. Recirculation mode can be used with vent and bi-level modes, but it cannot be used with ﬂoor, defog or defrost modes. Defog and defrost modes are described later in this section. If recirculation mode is selected with ﬂoor, defog, or defrost modes, the indicator will ﬂash three times and then turn off indicating the selection is not available. You may also notice that the air conditioning compressor will run while in recirculation mode. This is normal and will help to prevent fogging. If the weather is cold and damp, the system may cause the windows to fog while using recirculation mode. If the windows do start to fog, select defog or defrost mode and increase fan speed. Recirculation mode, if selected, will be cleared when the engine is turned off. 3-26 #A/C (Air Conditioning): Press this button to manually turn the air conditioning system on or off. When the system is on, the system will automatically begin to cool and dehumidify the air inside of your vehicle. The air conditioning symbol will appear on the display when the air conditioning is on and will turn off when the air conditioning is off. If you turn the air conditioning off while in front defrost or defog mode, the air conditioning symbol will turn off, however, the A/C compressor will remain on to help de-humidify the air inside the vehicle. If one of the other modes is selected the compressor will then turn the A/C off until it is selected again or the AUTO button is pressed. To avoid fogging the inside glass on rainy and humid days at a temperature above freezing, press the air conditioning button to run the A/C compressor. Also it is best to avoid the use of the recirculation mode except when maximum air conditioning performance is needed or for short times to avoid exterior odors. You may notice a slight change in engine performance when the air-conditioning compressor shuts off and turns on again. This is normal. Defogging and Defrosting Fog on the inside of the windows is a result of moisture condensing on the cool window glass. This can be reduced if the climate control system is used properly. You can use either defog or front defrost to clear fog or frost from your windshield. -(Defog): Use this setting to clear the windows of fog or moisture. This setting will deliver air to the ﬂoor and windshield outlets. 0(Front Defrost): Press the front defrost button to clear the windshield and side windows of frost or fog quickly. 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. Do not drive the vehicle until all the windows are clear. Rear Window Defogger If your vehicle has the rear window defogger a warming grid is used 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. The rear window defogger will turn off approximately 10 minutes after the button is pressed. If you need additional warming time, press the button again. If your vehicle has heated mirrors, they will come on when this button is pressed. 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. 3-27 Outlet Adjustment Use the air outlets located in the center and on the side of the instrument panel to direct the airﬂow. Use the thumbwheels near the air outlets to open or close off the airﬂow. Operation Tips (cid:127) Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the ﬂow of air into the vehicle. (cid:127) Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. (cid:127) Use of non-GM approved hood deﬂectors can adversely affect the performance of the system. Check with your dealer/retailer before adding equipment to the outside of your vehicle. Rear Climate Control System Your vehicle has one of the following rear climate control systems. With either of these systems, the rear climate controls will be disabled when the front climate control system is in defrost. This occurs to provide maximum airﬂow to clear the windshield. 3-28 The temperature of the air coming through the rear outlets is determined by the front passenger temperature setting. Use the mode knob to change the direction of airﬂow (upper, bi-level or ﬂoor) to the rear seat area. PWR (Power): Press this button to turn the rear climate controls on or off. H (Panel): This position distributes air from the rear console outlets. ) (Bi-level): This position distributes air from the second seat side ﬂoor outlets and the rear console outlets. 6 (Floor): This position distributes air from the second seat side ﬂoor outlets. P (On/Off): Press this button to turn the rear climate controls on or off. z9 y (Fan): Press this button to adjust the fan speed. z\ y (Mode): Press this button to change the direction of airﬂow (panel, bi-level or ﬂoor) to the rear seat area. The rear control only turns on if the front climate control system is on and not in defrost mode. If your vehicle has the rear seat audio system, the lower buttons are used to adjust the rear seat climate control system. The temperature of the air coming through the rear outlets is determined by the front passenger temperature setting. 3-29 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’re 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’s 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’re a big help. Your vehicle may also have a Driver Information Center (DIC) that works along with the warning lights and gages. See Driver Information Center (DIC) on page 3-49. 3-30 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 Uplevel version shown, Canada and Base similar 3-31 Speedometer and Odometer The speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). The odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). The odometer mileage can be checked without the vehicle running. Press the trip stem located on the instrument panel cluster. If your vehicle 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. The odometer works together with the Driver Information Center (DIC). You can set a Trip A and Trip B odometer. See “Trip Information” under DIC Operation and Displays on page 3-50. The odometer mileage can be checked without the vehicle running. Press the trip stem on the instrument panel cluster. 3-32 Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). Safety Belt Reminders Safety Belt Reminder Light When the engine is started, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver’s safety belt is already buckled. The safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light is repeated if the driver remains unbuckled and the vehicle is in motion. If the driver’s belt is already buckled, neither the chime nor the light will come on. Passenger Safety Belt Reminder Light Several seconds after the engine is started, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 1-61 for more information. The passenger safety belt light, located on the instrument panel, will come on and stay on for several seconds and then ﬂash for several more. This chime and light are repeated if the passenger remains unbuckled and the vehicle is in motion. Airbag Readiness Light There is an airbag readiness light on the instrument panel cluster, which shows the airbag symbol. The system checks the airbag’s electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the airbag sensor, the pretensioners, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 1-53. This light will come on when you start your vehicle, and it will ﬂash for a few seconds. The light should go out and the system is ready. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. 3-33 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. Passenger Airbag Status Indicator Your vehicle has the passenger sensing system. Your rearview mirror has a passenger airbag status indicator. {CAUTION: If the airbag readiness light stays on after you start your vehicle, it means the airbag system may not be working properly. The airbags in your vehicle may not inﬂate in a crash, or they could even inﬂate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the airbag readiness light stays on after you start your vehicle. The airbag readiness light should ﬂash for a few seconds when you start the engine. If the light does not come on then, have it ﬁxed immediately. If there is a problem with the airbag system, an airbag Driver Information Center (DIC) message may also come on. See DIC Warnings and Messages on page 3-53 for more information. 3-34 United States Canada When you start the vehicle, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol to let you know the status of the right front passenger’s frontal airbag. If the word ON or the on symbol is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inﬂate). {CAUTION: If the on indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Do not use a rear-facing child restraint in the right front passenger’s seat if the airbag is turned on. {CAUTION: Even though the passenger sensing system is designed to turn off the right front passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off. If the word OFF or the off symbol is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. See Passenger Sensing System on page 1-61 for more on this, including important safety information. 3-35 If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer/retailer for service. {CAUTION: If the airbag readiness light in the instrument panel cluster ever comes on and stays on, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger’s seat may not have the protection of the airbag(s). See Airbag Readiness Light on page 3-33 for more on this, including important safety information. Charging System Light This light will come on brieﬂy when you turn on the ignition key, but the engine is not running, as a check to show you it is working. It should go out once the engine is running. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system Driver Information Center (DIC) message may also appear. See DIC Warnings and Messages on page 3-53 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If you must drive a short distance with the light on, be certain to turn off all the accessories, such as the radio and air conditioner. 3-36 Voltmeter Gage When your engine is not running, but the ignition is on, this gage displays the battery voltage in DC volts. When the engine is running, the gage shows the condition of the charging system. The gage may transition from a higher to lower or a lower to higher reading, this is normal. Readings between the low and high warning zones indicate the normal operating range. The voltmeter gage may also read lower when in fuel economy mode. This is normal. 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 idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. You can only drive for a short time with the 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. 3-37 Brake System Warning Light When the ignition is on, the brake system warning light will come on when you set your parking brake. 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 your vehicle has a brake problem. A chime may also sound when the light comes on. 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. This light should come on brieﬂy when you turn the ignition key to RUN. If it does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If the light comes on while you are driving, pull off the road and stop carefully. You may notice that the pedal is harder to push or the pedal may go closer to the ﬂoor. It may take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 4-40. {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 3-38 StabiliTrak® Service Light This light will come on brieﬂy when the engine is started. This light will come on if a problem is detected in the StabiliTrak® system. For more information see StabiliTrak® System on page 4-6. Antilock Brake System Warning Light For vehicles with the Antilock Brake System (ABS), this light comes on brieﬂy when the engine is started. That is normal. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. If the ABS light stays on, turn the ignition off, if the light comes on when you are driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light still stays on, or comes on again while you are driving, your vehicle needs service. If the regular brake system warning light is not on, your vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, your vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 3-38. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 3-53 for all brake related DIC messages. 3-39 StabiliTrak® Indicator Light Engine Coolant Temperature Gage This warning light should come on brieﬂy when the engine is started. During most driving conditions, this light will not come on. If the StabiliTrak® System is actively controlling the stability and/or traction of the vehicle, this light will ﬂash. This is normal. This light will come on if any portion of the system has been manually turned off or a problem is detected in the system. If your vehicle has a Driver Information Center, a message will appear also, see DIC Warnings and Messages on page 3-53 and StabiliTrak® System on page 4-6 for more information. United States Canada This gage shows the engine coolant temperature. If the gage pointer moves into the red area, it means that the engine coolant has overheated. If you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. See Engine Overheating on page 5-28 for more information. 3-40 Tire Pressure Light Your vehicle has a tire pressure light. This light comes on brieﬂy when the engine is started and provides information about tire pressures and the Tire Pressure Monitoring System. When the Light is Solid This indicates that one or more of your tires are signiﬁcantly underinﬂated. A tire pressure message in the Driver Information Center (DIC), may accompany the light. See DIC Warnings and Messages on page 3-53 for more information. Stop and check your tires as soon as it is safe to do so. If underinﬂated, inﬂate to the proper pressure. See Tires on page 5-57 for more information. When the Light Flashes First and Then is Solid This indicates that there may be a problem with the Tire Pressure Monitor System. The light ﬂashes for about a minute and stays on solid for the remainder of the ignition cycle. This sequence will repeat with every ignition cycle. See Tire Pressure Monitor System on page 5-67 for more information. Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It makes sure that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment. The check engine light comes on to indicate that there is an OBD II problem and service is required. 3-41 This light comes on, as a check to show it is working, when the ignition is turned ON/RUN but the engine is not running. If the light does not come on, have it repaired. This light also comes on during a malfunction in one of two ways: Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and could damage the emission control system on your vehicle. Diagnosis and service might be required. Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service might be required. If you keep driving your vehicle with Malfunctions often are indicated by the system before any problem is apparent. This can prevent more serious damage to your vehicle. This system is also designed to assist your service technician in correctly diagnosing any malfunction. Notice: this light on, after a while, the emission controls might not work as well, your vehicle’s fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by your warranty. Notice: Modiﬁcations made to the engine, transmission, exhaust, intake, or fuel system of your vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission controls and can cause this light to come on. Modiﬁcations to these systems could lead to costly repairs not covered by your warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modiﬁcations on page 5-3. 3-42 (cid:127) (cid:127) If the Light is Flashing The following can prevent more serious damage to your vehicle: (cid:127) Reduce vehicle speed. (cid:127) Avoid hard accelerations. (cid:127) Avoid 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 the vehicle. Turn the ignition 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/retailer for service as soon as possible. If the Light Is On Steady You might 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 been left off or improperly installed. A loose or missing fuel cap allows 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 vehicle’s electrical system might be wet. The condition is usually 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 5-6. Poor fuel quality causes the engine not to run as efficiently as designed. You might 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 might 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/retailer can check the vehicle. Your dealer/retailer has the proper test equipment and diagnostic tools to ﬁx any mechanical or electrical problems that might have developed. 3-43 (cid:127) 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). Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might 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 the battery or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can 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/retailer can prepare the vehicle for inspection. 3-44 {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. Always follow the maintenance schedule in this manual for changing engine oil. Oil pressure may vary with engine speed, outside temperature and oil viscosity, but readings above the low pressure zone indicate the normal operating range. A reading in the low pressure zone may be caused by a dangerously low oil level or other problems causing low oil pressure. Change Engine Oil Light Your vehicle may have a change engine oil light. When this light comes on it means that an oil change and other maintenance procedures are required for your vehicle. See Scheduled Maintenance on page 6-4 and Engine Oil on page 5-16 for more information. Once the engine oil has been changed, the change engine oil light must be reset. Until it is reset, the light will stay on when the engine is on. 3-45 Security Light Reduced Engine Power Light For information regarding this light and the vehicle’s security system, see Content Theft-Deterrent on page 2-16. This light comes on when a noticeable reduction in the vehicle’s performance occurs. Cruise Control Light If your vehicle has a Driver Information Center (DIC), this light will come on when the cruise control is set. See Cruise Control on page 3-11 and DIC Warnings and Messages on page 3-53 for more information. The vehicle can be driven at a reduced speed when the reduced engine power light is on, but acceleration and speed may be reduced. The performance may be reduced until the next time you drive your vehicle. If this light stays on, see your dealer as soon as possible for diagnosis and repair. This light may also come on if there is a problem with the Electronic Throttle Control (ETC) system. If this happens, take the vehicle in for service as soon as possible. 3-46 Highbeam On Light This light comes on when the high-beam headlamps are in use. See Headlamp High/Low-Beam Changer on page 3-8 for more information. Service Four-Wheel Drive Warning Light The service four-wheel drive light comes on to indicate that there may be a problem with the drive system and service is required. Malfunctions can be indicated by the system before any problem is apparent, which may prevent serious damage to the vehicle. This system is also designed to assist your dealer in correctly diagnosing a malfunction. Check Gages Warning Light The check gages light will come on brieﬂy when you are starting the engine. This light should come on brieﬂy when you turn on the ignition, as a check to show you it is working. If the light comes on and stays on while you are driving, check your coolant temperature and engine oil pressure gages to see if they are in the warning zones. 3-47 Gate Ajar Light If this light comes on, the liftgate or liftglass is not completely shut. Close the liftgate or liftglass. Never drive with the liftgate or liftglass even partially open. Fuel Gage When the ignition is on, the fuel gage tells you about how much fuel you have remaining. Here are four things that some owners ask about. None of these show a problem with your fuel gage: (cid:127) At the gas station, the gas pump shuts off 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. The gage moves a little when you turn a corner or speed up. The gage doesn’t go back to empty when you turn off the ignition.
