Your front and rear turn signal lamps will ﬂash on and off. The hazard warning ﬂasher button is located in the center of the instrument panel. Your hazard warning ﬂashers work no matter what position your key is in, and even if the key is not in the ignition switch. Press the button to make the front and rear turn signal lamps ﬂash on and off. Press the button again to turn the ﬂashers off. When the hazard warning ﬂashers are on, your turn signals will not work. 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 near or on the horn symbols on your steering wheel pad to sound the horn. 150 Tilt Wheel If the vehicle has a tilt wheel it lets you adjust the steering wheel before you drive. The steering wheel can be raised to the highest level to give the driver’s legs more room when you enter and exit the vehicle. The lever that allows you to tilt the steering wheel is located on the left side of the steering column. Telescoping Column If the vehicle has a telescoping column on the steering wheel that adjusts the distance of the steering wheel to the driver without moving the driver’s seat. The lever that makes this adjustment is located on the left side of the steering column and behind the tilt lever, if the vehicle has this feature. To tilt the wheel, pull the lever down. Then move the wheel to a comfortable position and pull the lever up to lock the wheel in place. To adjust the steering wheel, pull the steering wheel column lever down and push or pull the steering wheel to a comfortable position. Then pull the lever up to lock the wheel in place. Do not drive the vehicle unless the telescoping column is locked. 151 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. See Turn and Lane-Change Signals on page 152. (cid:127) 2 Headlamp High/Low-Beam Changer. See Headlamp High/Low-Beam Changer on page 153. (cid:127) Flash-to-Pass. See Flash-to-Pass on page 153. (cid:127) N Windshield Wipers. See Windshield Wipers on page 153. (cid:127) LQ Windshield Washer. See Windshield Washer on page 154. For information on the headlamps, see Exterior Lamps on page 158. 152 Turn and Lane-Change Signals To signal a turn, move the lever up or down. The lever returns to its original position when the turn is completed. An arrow on the instrument panel cluster will ﬂash 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 the lane change is completed. The lever will return to its original position when released. Arrows that ﬂash rapidly when signaling for a turn or lane change, or that fail to work, may indicate a burned-out signal bulb or fuse. Other drivers will not see the signal. See Front Turn Signal and Parking Lamps on page 397 and Taillamps, Turn Signal, Sidemarker, Stoplamps and Back-up Lamps on page 398 for turn signal bulb replacement procedures. Also see Fuses and Circuit Breakers on page 450 for location of fuses. A chime will sound if the turn signal is left on for more than 3/4 mile (1.2 km). Headlamp High/Low-Beam Changer To change the headlamps from low beam to high beam, push the turn signal/multifunction lever away from you. When the high beams are on, a light on the instrument panel cluster also will be on if the ignition is on. To change the headlamps from high beam to low beam, pull the turn signal lever toward you. Flash-to-Pass This feature lets you use your high-beam headlamps momentarily to signal a driver in front of you that you want to pass. To use it, pull the turn signal/multifunction lever toward you until the high-beam headlamps come on, then release the lever to turn them off. Windshield Wipers Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, gently loosen or thaw them. Damaged wiper blades may not clear the windshield well, making it harder to see and drive safely. If the blades do become damaged, install new blades or blade inserts. For more information, see Windshield Wiper Blade Replacement on page 401. Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down. Clear away snow or ice to prevent an overload. 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 wipe cycles, hold the band on mist longer. 153 {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. Cruise Control With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). 6 (Delay): You can set the wiper speed for a long or short delay between wiping cycles. 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. Windshield Washer 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 your preset speed. 154 {CAUTION: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use your cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads. If your vehicle is in cruise control when the Traction Control System (TCS), if your vehicle has this feature, begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control System (TCS) on page 294. When road conditions allow you to safely use it again, the cruise control can be turned back on. The cruise control buttons are located on left side of the steering wheel. T (On/Off): Press this button to turn cruise control on and off. The indicator will be lit when cruise control is on. + RES (Resume/Accelerate): Press this button to make the vehicle accelerate or resume to a previously set speed. SET–: Press this button to set the speed or make the vehicle decelerate. [ (Cancel): Press this button to cancel cruise control. 155 Resuming a Set Speed Suppose you set the cruise control at a desired speed and then you apply the brake. This shuts off the cruise control, but it does not need to be reset. Once you are driving about 25 mph (40 km/h) or more, press the +RES button on the steering wheel. The vehicle will go back to your chosen speed and stay there. Increasing Speed While Using Cruise Control To increase the cruise speed while using cruise control: (cid:127) Press and hold the +RES button on the steering wheel until you reach your new desired speed, then release it. (cid:127) To increase vehicle speed in small increments, press the +RES button. Setting Cruise Control Cruise control will not work if the parking brake is set, or if the master cylinder brake ﬂuid level is low. The cruise control light on the instrument panel cluster will come on after the cruise control has been set to the desired speed. See Instrument Panel Cluster on page 180. {CAUTION: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control. 1. Press the cruise control on/off button. 2. Get up to the speed you want. 3. Press and release the SET– button located on the steering wheel. 4. Take your foot off the accelerator. 156 Reducing Speed While Using Cruise Control To reduce your speed while using cruise control: (cid:127) Press and hold the SET– button on the steering wheel until you reach the lower speed you want, then release it. (cid:127) To slow down in very small amounts, press the SET– button on the steering wheel brieﬂy. Each time this is done, you will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the cruise speed you set earlier. Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle speed, load and the steepness of the hills. When going up steep hills, you may have 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 ends the cruise control. Many drivers ﬁnd this to be too much trouble and do not use cruise control on steep hills. Ending Cruise Control There are three ways to end cruise control: (cid:127) Step lightly on the brake pedal. (cid:127) Press the [ (cancel) button on the steering wheel. (cid:127) Press the T (on/off) button on the steering wheel. Erasing Speed Memory The cruise control set speed memory is erased by turning off the cruise control or the ignition. 157 To enable automatic lighting, do any of the following: (cid:127) Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. (cid:127) Turn the headlamp control from the parking lamp position to AUTO. (cid:127) Turn the headlamp control from the headlamp position to AUTO. To disable automatic lighting, do any of the following: (cid:127) Turn the headlamp control from AUTO to off and release the control. It will return back to the AUTO position by itself. (cid:127) Turn the headlamp control from AUTO to the parking lamp position. (cid:127) Turn the headlamp control from AUTO to the headlamp position. Exterior Lamps The control located to the left of the cluster on the instrument panel, operates the exterior lamps. P(On/Off): Turn the control to this position to manually turn the headlamps on and off. This is a momentary control that will spring back to AUTO when released. AUTO (Automatic): Turn the control to this position to set your headlamps in automatic mode. AUTO mode, if enabled, will turn the exterior lamps on and off automatically depending on how much light is available outside the vehicle. 158 Instrument Panel Lights <(Parking Lamps): Turn the control to this position to turn on the parking lamps together with the following: (cid:127) Taillamps (cid:127) License Plate Lamps (cid:127) Sidemarker Lamps (cid:127) 2(Headlamps): Turn the control to this position to turn your headlamps on, together with the previously listed lamps and lights. A warning chime will sound if the driver’s door is opened when the ignition switch is turned to OFF or ACCESSORY and the headlamps or parking lamps are on. -(Foglamps): If your vehicle has fog lamps, press this button to turn them on and off. See Fog Lamps on page 160 for additional information. Daytime Running Lamps (DRL)/ Automatic Headlamp System 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. DRL lamps are required to function at all times on all vehicles ﬁrst sold in Canada. A light sensor on top of the instrument panel makes the DRL work, so be sure it is not covered. The DRL system will make the low-beam headlamps come on at reduced brightness when the following conditions are met: (cid:127) The ignition is on. (cid:127) The exterior lamps control is off. (cid:127) The parking brake is released. While the DRL are on, only the vehicle’s low-beam headlamps will be on at reduced brightness. The turn signal, taillamps, sidemarker, and other lamps will not be on. The instrument panel will not be lit up either. 159 When it is dark enough outside, the DRL will turn off and the vehicle’s headlamps and parking lamps will turn on. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will come on. To idle the vehicle with the DRL off, turn the exterior lamp control off and then do one of the following: (cid:127) Turn the exterior lamp control to the parking lamp position. (cid:127) Turn the exterior lamp control to the headlamp position. (cid:127) Turn the exterior lamp control from AUTO to off and back to AUTO. This feature is not available for vehicles ﬁrst sold in Canada. To turn off the automatic headlamp feature when it is dark outside, move the exterior lamp control to the parking lamp position. The parking lamps remain on and the headlamps turn off. The fog lamps also go on if they were on previously. As with any vehicle, the regular headlamp system should be turned on when needed. 160 Fog Lamps If your vehicle has fog lamps, the button is located in the center of the exterior lamps control on the left side of the steering column. Press the fog lamps button to turn the lamps on or off. While the high-beam headlamps are on, the fog lamps are off. Some localities have laws that require the headlamps to be on along with the fog lamps. Exterior Lighting Battery Saver If the parking lamps or headlamps have been left on after the ignition has been turned to off, the exterior lamps will turn off after about 10 minutes. This protects the battery from being drained. Use the exterior lamp control to turn the lamps back on, if they are still needed. Interior Lamps Your interior lamps control is located next to the exterior lamps control and to the left of the steering wheel on the instrument panel. 9(Off): Turn the control to this position to disable courtesy lamps, entry lighting, delayed entry lighting, and delayed exit lighting. 1(Door): Turn the control to this position to turn the interior lamps on when any door is open and when the ignition key is removed from the ignition. +(On): Turn the control to this position to turn on the interior lamps. The interior lamps can be controlled, or automatically turned on or off under certain conditions. They are explained in the following text. Instrument Panel Brightness The instrument panel lights can be brightened or dimmed by pressing the center knob of the interior lamp controls until it pops out. Turn the knob clockwise to brighten the lights or counterclockwise to dim them. Courtesy Lamps Courtesy lamps come on to make it easier to enter and exit the vehicle. These lamps will come on when the interior lamp control is in the door position and any door is opened. Entry Lighting The courtesy lamps will come on and stay on for a set time whenever the interior lamp control is in the door position and the UNLOCK button on the Remote Keyless Entry (RKE) transmitter is pressed. The lamps will stay on while a door is opened and then turn off automatically about 25 seconds after it is closed. If the UNLOCK button is pressed and a door is not opened, the lamps will turn off after about 25 seconds. 161 Entry lighting includes a feature called theater dimming. With theater dimming, the lamps do not turn off at the end of the delay time. Instead, they slowly dim after the delay time and then turn off. The courtesy lamps turn off when the ignition key is turned to RUN or START. They will come on again when a door is opened. Delayed Entry Lighting Delayed entry lighting lights the vehicle’s interior for a period of time after all the doors have been closed. After all the doors have been closed, the delayed entry lighting feature will continue to work until one of the following occurs: (cid:127) The ignition is in RUN. (cid:127) The doors are locked. (cid:127) 25 seconds has passed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on. 162 Theater Dimming This feature allows for a three to ﬁve-second fade out of the courtesy lamps instead of immediate turn off. Delayed Exit Lighting This feature can be programmed either on or off using the Driver Information Center. See DIC Vehicle Personalization on page 229 under INT (Interior) LIGHTS KEYS REMOVED. When activated, this feature illuminates the interior for a period of time after the ignition key is removed from the ignition. The ignition must be off and the interior lamp control must be in the door position for delayed exit lighting to work. When the ignition key is removed, interior illumination will activate and remain on until one of the following occurs: (cid:127) The ignition is in RUN. (cid:127) The power door locks are activated. (cid:127) 25 seconds has passed. If during the illumination period a door is opened, the timed illumination period will be canceled and the interior lamps will remain on. Perimeter Lighting Perimeter lighting provides a period of exterior vehicle lighting. Perimeter lighting activates when the key is removed from the ignition or the vehicle is unlocked using the Remote Keyless Entry (RKE) transmitter. The amount of time the exterior lamps will remain on can be programmed using the Driver Information Center (DIC). See “EXIT LIGHT DELAY” under DIC Vehicle Personalization on page 229 for additional information. Overhead Console Reading Lamps Your vehicle may have reading lamps located on the overhead console. Press the lens to turn them on and off. Rear Assist Handle Reading Lamps Your vehicle may have reading lamps located near the rear assist handles. Press the lens to turn them on and 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 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. 163 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. 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, the Driver Information Center (DIC) message might display Battery Saver Active. 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 208. Battery Run-Down Protection This helps prevent the vehicle’s battery from draining in case the interior courtesy lamps, reading lamps, trunk lamp, underhood lamp, glove box lamps, or sun visor vanity lamps, if equipped, are accidently left on. If any of these lamps are left on while the ignition is off, they will automatically turn off after 10 minutes. The lamps will not come back on again until one of the following occurs: (cid:127) The ignition is turned on. (cid:127) The interior lamps control is turned off, then to door or on. Ultrasonic Rear Parking Assist (URPA) Your vehicle may be equipped with Ultrasonic Rear Parking Assist (URPA). URPA is designed to help you park while in REVERSE (R) and operates only at speeds less than 3 mph (5 km/h). URPA can help you avoid colliding with objects such as parked vehicles. The system can detect objects 5 feet (1.5 m) behind your vehicle and tell you how close those objects are to your rear bumper. 164 The URPA display is located inside the vehicle, above the rear window. It has three color-coded lights that can be seen through the rearview mirror or by turning around. {CAUTION: The Ultrasonic Rear Park Assist (URPA) system does not replace driver vision. URPA does not: (cid:127) Operate above speeds of 3 mph (5 km/h). (cid:127) Detect objects more than 5 feet (1.5 meters) behind the vehicle. This distance may be less during warmer or humid weather. (cid:127) Detect objects that are below the bumper, underneath the vehicle, or that are very close to the vehicle. (cid:127) Detect children, pedestrians, bicyclists, or pets. CAUTION: (Continued) CAUTION: (Continued) So if you do not use proper care before backing up, you could hit a vehicle, child, pedestrian, bicyclist, or pet, resulting in vehicle damage, injury, or death. Even though the vehicle has the URPA system, always check carefully before backing up by checking behind your vehicle. How the System Works URPA comes on automatically when the shift lever is moved into REVERSE (R). When the system comes on, the three lights on the display will brieﬂy illuminate to let you know that the system is working. If your vehicle is moving in REVERSE (R) at a speed greater than 3 mph (5 km/h), the red light will ﬂash to remind you the system does not work at this speed. 165 The ﬁrst time an object is detected while in REVERSE (R), a chime will sound and the following will occur in sequence, depending on the distance from the object: (cid:127) At 5 feet (1.5 m) a chime will sound and one amber light will be lit. (cid:127) At 40 inches (1.0 m) both amber lights will be lit. (cid:127) At 20 inches (0.5 m) a continuous chime will sound and all three lights (amber/amber/red) will be lit. (cid:127) At 1 foot (0.3 m) a continuous chime will sound and all three lights (amber/amber/red) will ﬂash. URPA can detect objects 3 inches (7.6 cm) and wider, and at least 10 inches (25.4 cm) tall, but it cannot detect objects that are above trunk level. In order for the rear sensors to recognize an object, it must be within operating range. If the URPA system is not functioning properly, the display will ﬂash red, indicating that there is a problem. The light will also ﬂash red while driving if a trailer is attached to your vehicle, or a bicycle or object is on the back of, or hanging out of your 166 trunk. The light will continue to ﬂash until the trailer or the object is removed and your vehicle is driven forward at least 15 mph (25 km/h). It may also ﬂash red if the ultrasonic sensors are not kept clean. So be sure to keep your rear bumper free of mud, dirt, snow, ice and slush or materials such as paint or the system may not work properly. If after cleaning the rear bumper and driving forward at least 15 mph (25 km/h), the display continues to ﬂash red, see your GM dealer. For cleaning instructions, see Washing Your Vehicle on page 442. It may also ﬂash red if your vehicle is moving in REVERSE (R) at a speed greater than 3 mph (5 km/h). Other conditions that may affect system performance include things like the vibrations from a jackhammer or the compression of airbrakes on a very large truck. As always, drivers should use care when backing up a vehicle. Always look behind you, being sure to check for other vehicles, obstructions and blind spots. Accessory Power Outlet(s) The accessory power outlets enable power electrical equipment such as a cellular telephone or a CB radio to be used inside the vehicle. Your vehicle has 12-volt outlets. One outlet is located on the center console below the climate controls. There may be another outlet located inside the center storage console or in the ﬂip and fold console. Open the cover to use the outlet. Be sure to close the cover when the outlet is not in use. Notice: Adding any electrical equipment to your vehicle may damage it or keep other components from working as they should. The repairs would not be covered by your warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer before adding electrical equipment. Certain power accessory plugs may not be compatible to the power accessory outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer. Notice: Improper use of the power outlet can cause damage not covered by your warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only. Notice: Leaving electrical equipment plugged in for an extended period of time while the vehicle is off will drain the battery. Power is always supplied to the outlets. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum 20 ampere rating. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. 167 Climate Controls Climate Control System With this system you can control the heating, cooling and ventilation for your vehicle. If your vehicle has the remote start feature and it is activated, the climate control system will automatically cool the vehicle if the temperature is greater than 90°F (32°C) and heat the vehicle if the temperature is below 37°F (3°C). If the temperature is between 37°F (3°C) and 90°F (32°C), the last control setting selected when the engine was running will be used. Normal operation and the last setting of the climate control system will return after the key is turned to the RUN position. If you put papers, pins, or other Ashtray(s) and Cigarette Lighter Your vehicle may have a removable ashtray and cigarette lighter. The cigarette lighter may be located under the climate control system. The removable ashtray can be placed into the front console cupholder. Notice: ﬂammable items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your vehicle. Never put ﬂammable items in the ashtray. To use the cigarette lighter, push it in all the way, and let go. When the heating element 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. 168 Use the right knob to select from the following modes: H(Vent): This mode directs outside air to the instrument panel outlets. If driving in city traffic, and the vehicle is stopped and idling, or the weather is hot, turning on the recirculation mode helps to prevent the air inside the vehicle from becoming stale. After ﬁve minutes recirculate will allow some outside air into the vehicle. )(Bi-Level): This mode directs half of the air to the instrument panel outlets, and the remaining air to the ﬂoor outlets. Some air may be directed toward the windshield. Slightly cooler air is directed to the instrument panel outlets and warmer air is directed to the ﬂoor outlets. 6(Floor): This mode directs most of the air to the ﬂoor outlets with some air directed toward the side window outlets and a little air directed to the windshield. In this mode, the system will automatically use outside air. The air conditioning compressor will be engaged unless the outside temperature is 40°F (4°C) or below. 169 Operation OFF: Turn the left knob to this position to turn the climate control system off. 9(Fan): Turn the knob by this symbol, located on the left side of the climate control panel, clockwise or counterclockwise to increase or decrease the fan speed. The fan speed will be temporarily reduced between the transition to a new mode. The fan will resume the original speed when the transition to the new mode is complete. Temperature Control: Turn the center knob clockwise or counterclockwise to increase or decrease the temperature inside your vehicle. You can also select modes by using the following buttons: h(Recirculate): Press this button to recirculate cabin air through the vehicle. It can be used to help reduce the outside air and odors that enter your vehicle or to help heat or cool the air inside your vehicle quicker. An indicator light below the button will come on in this mode. Operation in this mode during periods of high humidity and cool outside temperatures may result in increased window fogging. If window fogging is experienced, select the defrost mode. To prevent the air inside the vehicle from becoming stale, after ﬁve minutes recirculate will allow some outside air into the vehicle. #(Air Conditioning): Press this button to turn the air conditioning system on or off. When this button is pressed, an indicator light below the button will come on to let you know the air conditioning is activated. Air conditioning can be selected in any mode as long as the fan switch is on. The indicator light will change with each button press even when conditions prevent operation. On hot days during the vehicle’s initial start-up, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. For quicker cool down on hot days, do the following: 1. Select the vent air mode. 2. Select the recirculation mode. 3. Select the air conditioner. 4. Select the coolest temperature. 5. Select the highest fan speed. The air conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. Using these settings together for long periods of time may cause the air inside the vehicle to become too dry. To prevent this, after ﬁve minutes recirculate will allow some outside air into the vehicle. 170 Defogging and Defrosting Fog on the inside of the vehicle is a result of high humidity causing moisture to condense on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear frost or fog from the windshield. Use the defog mode to clear the windows of condensation and to warm the vehicle’s occupants. Use the defrost mode to remove frost or condensation from the windshield quickly. See “Rear Window Defogger” later in this section for information on clearing the rear window of fog or ice. Turn the right knob to select the defog or defrost mode. Do not drive the vehicle until all windows are clear. -(Defog): This mode directs half of the air to the windshield and the side window outlets and half to the ﬂoor outlets. When you select this mode, the system turns recirculation off and runs the air conditioning compressor unless the outside temperature is near or below freezing. Pressing the recirculation button will have no effect other than turning on the indicator light while in defog mode. 0(Defrost): This mode directs most of the air to the windshield and the side window outlets, with some air directed to the ﬂoor outlets. When you select this mode, the system turns recirculation off and runs the air conditioning compressor unless the outside temperature is near or below freezing. Pressing the recirculation button will have no effect other than turning on the indicator light while in defrost mode. 171 Dual Automatic Climate Control System With this system you can control the heating, cooling, and ventilation for the vehicle. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. <(Rear): Press the button to turn the rear window defogger on or off. An indicator light below the button will come on to let you know that the rear window defogger is activated. The rear window defogger will only work when the ignition is in RUN. The rear window defogger will stay on for about 20 minutes after the button is pressed. If turned on again, the defogger will only run for about 20 minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all windows are clear. 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. 172 Automatic Operation AUTO (Automatic): Press the AUTO button for automatic control of the inside temperature, the air delivery mode, and the fan speed. There might be a delay of two to three minutes before the fan comes on when the automatic operation is used in cold weather. For the automatic system to function, the temperature must be set between 61°F (15°C) and 89°F (32°C). 1. Adjust the temperature to a comfortable setting. 2. Press the PASS button or the up or down arrows on the passenger side to turn the passenger temperature set on and off. When turned on, the passenger temperature will be the same as the driver setting. Press the up or down arrow on passenger side to adjust the passenger temperature setting. When the passenger’s temperature set is off, the passenger display will be off and the driver’s set temperature will be for the driver and passenger. In cold weather, the system will start at reduced fan speeds to avoid blowing cold air into the vehicle until warmer air is available. The system will start out blowing air at the ﬂoor but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up will depend on the outside temperature and the length of time that has elapsed since the vehicle was last driven. 3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then, adjust the temperature, if necessary. Do not cover the solar sensor located in the center of the instrument panel, near the windshield. For more information on the solar sensor, see “Sensors” later in this section. 4. Press OFF to turn the climate control system off. Only the rear defog and heated seats will function. Press AUTO or any other button except the heated seats or rear defog to turn the climate control system back on. 173 This control has four types of operation.

A small amount of air is also directed to the windshield and the side window outlets. Y(Vent): This mode directs air through the instrument panel outlets. h(Recirculation): Press this button to turn recirculation mode on or off. This mode keeps outside air from coming into the vehicle. It can be used to help reduce the outside air and odors that enter your vehicle or help cool the air inside the vehicle quicker. Recirculation is not available while in the ﬂoor, defrost, or ﬂoor/defog modes. Using recirculation for long periods of time may cause the air inside your vehicle to become too dry. Recirculation mode has a ﬁve minute timer after which the system allows for some fresh outside air into the vehicle to maintain interior air quality. #(Air Conditioning): Press this button to turn the air conditioning compressor on and off. The indicator light on the button will come on when the air conditioning is on. The indicator light will change with each button press even when conditions prevent operation. ((Heated Seats): Press this button to turn the driver or passenger heated seats on and off. See Heated Seats on page 10 for additional information. 175 Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog or frost from your windshield. Use the ﬂoor/defog mode to clear the windows of fog or moisture and warm the passengers. Use defrost to remove fog or frost from the windshield more quickly. -(Floor/Defog): Press this button to direct the air between the windshield, ﬂoor outlets and side windows. When you select this mode, the system turns recirculation off and runs the air conditioning compressor unless the outside temperature is near or below freezing. Pressing the recirculation button will have no effect other than turning on the indicator light while in ﬂoor/defog mode. 1(Defrost): Press this button to direct most of the air to the windshield, with some air directed to the side windows. In this mode, the system will automatically turn off the recirculation and run the air conditioning compressor, unless the outside temperature is near or below freezing. Pressing the recirculation button will have no effect other than turning on the indicator light while in defrost mode. Do not drive the vehicle until all windows are clear. Sensors The solar sensor on the vehicle monitors the solar heat and the air inside of the vehicle. This information is used to maintain the selected temperature by initiating needed adjustments to the temperature, the fan speed, and the air delivery system. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be activated, as necessary. Do not cover the solar sensor located in the center of the instrument panel, near the windshield, or the system will not work properly. 176 Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The rear window defogger will only work when the engine is running. =(Rear Window Defogger): Press this button to turn the rear window defogger on and off. Be sure to clear as much snow from the rear window as possible. The rear window defogger will turn off about 20 minutes after the button is pressed. If turned on again, the defogger will only run for about 20 minutes before turning off. The defogger can also be turned off by pressing the button again or by turning off the engine. Do not drive the vehicle until all the windows are clear. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Outlet Adjustment Use the thumbwheels located between the center outlets to open and close the outlets. Move the lever in the center of each air outlet to adjust the direction of the airﬂow. Operation Tips (cid:127) Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the ﬂow of air into the vehicle. (cid:127) Use of non-GM approved hood deﬂectors may adversely affect the performance of the system. (cid:127) Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. (cid:127) This vehicle has a passenger compartment air ﬁlter. If the airﬂow seems low when the fan is at the highest setting it may need to be replaced. For more information, see Passenger Compartment Air Filter on page 178. 177 5. Peel back the hood weather-strip from the passenger’s side of the vehicle halfway to the center of the hood. 6. Remove the three air inlet grille retainers. 7. Remove the air inlet grille. 8. Remove the water deﬂector panel. 9. Remove the old air ﬁlter by pulling up on its tab. Passenger Compartment Air Filter The passenger compartment air ﬁlter is located in the engine compartment below the air inlet grille, near the passenger’s side windshield wiper arm. See Engine Compartment Overview on page 350. The ﬁlter traps most of the pollen from the air entering the air conditioning module. Like the engine’s air cleaner ﬁlter, it needs to be changed periodically to keep the air conditioning working at its best. For information on how often to change the passenger compartment air ﬁlter, see Scheduled Maintenance on page 462. To change the passenger compartment air ﬁlter, use the following steps: 1. Turn the ignition to ACCESSORY and turn the windshield wipers on. 2. Turn the ignition to OFF when the windshield wipers are in the upright position. 3. Raise the hood. 4. Disconnect the windshield washer pump hose from the fender rail and air inlet grille. 178 10. Install a new passenger compartment air ﬁlter. See Normal Maintenance Replacement Parts on page 471 for the type of ﬁlter to use. Make sure it slides under the compartment retainers. 11. Reverse Steps 1 through 8. For best climate control performance, re-installation of a clean air ﬁlter is required. Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on the 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 the warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of the 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 the warning lights and gages. They are a big help. 179 Instrument Panel Cluster The instrument panel cluster is designed to let the driver know at a glance how the vehicle is running. It will show how fast the vehicle is going, about how much fuel is in the fuel tank and many other things needed to drive safely and economically. 180 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 200. The odometer mileage can be checked without the vehicle running. Simply press the odometer/trip switch 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. Tachometer The tachometer displays the engine speed in thousands of revolutions per minute (rpm). Safety Belt Reminder Light When the key is turned to RUN or START, 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 will be 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. 181 Passenger Safety Belt Reminder Light Several seconds after the key is turned to RUN or START, a chime will sound for several seconds to remind the front passenger to buckle their safety belt. This would only occur if the passenger airbag is enabled. See Passenger Sensing System on page 75 for more information. The passenger safety belt light will also come on and stay on for several seconds, then it will ﬂash for several more. This chime and light will be repeated if the passenger remains unbuckled and the vehicle is in motion. If the passenger’s safety belt is buckled, neither the chime nor the light will come on. 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 system check includes the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 66. This light will come on when the vehicle is started, and it will ﬂash for a few seconds. Then the light should go out. This means the system is functioning properly. 182 If the airbag readiness light stays on after the vehicle is started, or comes on as the vehicle is being driven, there may be an electrical problem and the airbag system may not work properly. Have the 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 does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Passenger Airbag Status Indicator Your vehicle has a passenger sensing system. The passenger airbag status indicator on the instrument panel will be visible when you turn your ignition key to RUN or START. See Passenger Sensing System on page 75 for more information. The passenger airbag status indicator will light ON and OFF for several seconds as a system check. If you use remote start to start your vehicle from a distance, if your vehicle has this feature, you may not see the system check. Then, after several more seconds, the status indicator will light either ON or OFF to let you know the status of the right front passenger’s frontal airbag. 183 If the word ON is lit on the passenger airbag status indicator, it means that the right front passenger’s frontal airbag is enabled (may inﬂate). {CAUTION: If the on indicator comes on when you have a rear-facing child restraint installed in the right front passenger’s seat, it means that the passenger sensing system has not turned off the passenger’s frontal airbag. A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s airbag inﬂates. This is because the back of the rear-facing child restraint would be very close to the inﬂating airbag. Do not use a rear-facing child restraint in the right front passenger’s seat if the airbag is turned on. Your vehicle has a rear seat that will accommodate a rear-facing child restraint. A label on your sun visor says, “Never put a rear-facing child seat in the front.” This is because the risk to the rear-facing child is so great, if the airbag deploys. {CAUTION: Even though the passenger sensing system is designed to turn off the passenger’s frontal airbag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off. We recommend that rear-facing child restraints be secured in the rear seat, even if the airbag is off. If the word OFF is lit on the airbag status indicator, it means that the passenger sensing system has turned off the right front passenger’s frontal airbag. 184 See Passenger Sensing System on page 75 for more on this, including important safety information. If, after several seconds, all status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer for service. {CAUTION: If the off indicator and the airbag readiness light ever come on together, it means that something may be wrong with the airbag system. If this ever happens, have the vehicle serviced promptly, because an adult-size person sitting in the right front passenger seat may not have the protection of the frontal airbag. See Airbag Readiness Light on page 182. Charging System Light This light comes on brieﬂy when the ignition is turned on, as a check to show that it is working. Then it should go out. If it stays on, or comes on while the vehicle is being driven, a chime will sound and there may be a problem with the charging system. It could indicate that the vehicle has a loose accessory belt or another electrical problem. Have it checked right away. Driving while this light is on could drain the battery and result in the engine suddenly stopping. If the vehicle must be driven a short distance with the light on, be certain to turn off all unnecessary electrical loads, such as the radio, heater fan, air conditioning fan, and heated seats. 185 If the light comes on while you are driving, a chime will sound and you should 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 325. {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. Brake System Warning Light Your vehicle’s hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop you. For good braking, though, you need both parts working well. If the warning light comes on and the parking brake is not applied, there is 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. When the ignition is on, the brake system warning light will also 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 you have a brake problem. 186 Anti-Lock Brake System Warning Light Your vehicle may have the Anti-Lock Brake System (ABS). This light will come on when your engine is started and may stay on for several seconds. That is normal. If the ABS warning light comes on and stays on, there may be a problem with the anti-lock portion of the brake system. If the brake system warning light is not on, you still have brakes, but you do not have anti-lock brakes. See Brake System Warning Light on page 186. If the light stays on, turn the ignition to OFF. If the light comes on when you are driving, stop as soon as possible and turn the ignition off. Then start the engine again to reset the system. If the 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, you still have brakes, but you do not have anti-lock brakes. If the regular brake system warning light is also on, you do not have anti-lock brakes and there is a problem with your regular brakes. See Brake System Warning Light on page 186. The ABS warning light should come on brieﬂy when you turn the ignition key to RUN. If the light does not come on then, have it ﬁxed so it will be ready to warn you if there is a problem. Traction Control System (TCS) Warning Light Your vehicle may have a Traction Control System (TCS) warning light. If this warning light comes on and stays on, there may be a problem with the TCS and, if your vehicle has this feature, the StabiliTrak® system. 187 The TCS warning light will come on brieﬂy when you turn the ignition 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 TCS warning light stays on or comes on while you are driving, pull off the road as soon as possible and stop carefully. Try resetting the system by turning the ignition off then back on. If the light still stays on or comes back on again while you are driving, your vehicle needs service. Have the traction control system and, if your vehicle has this feature, the StabiliTrak® system inspected as soon as possible. See Traction Control System (TCS) on page 294 and StabiliTrak® System on page 296 for more information. Engine Coolant Temperature Warning Light This light tells you that your engine is very hot. This light will come on when you ﬁrst start the vehicle as a check to let you know that the light is working. It will go out after a few seconds. If the light does not come on, the bulb may be burned out. See your dealer to have it corrected. If the light does not go out or if the light comes on and stays on while you are driving, your vehicle may have a problem with the cooling system. You should stop the vehicle and turn off the engine as soon as possible to avoid damage to the engine. A warning chime will sound when this light is on, also. See Engine Overheating on page 367. 188 Engine Coolant Temperature Gage The vehicle has a gage that shows the engine coolant temperature. If the gage pointer moves towards the H, the engine is too hot. This reading indicates the same thing as the warning light. It means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull off the road, stop the vehicle, and turn off the engine as soon as possible. See Engine Overheating on page 367. Low Coolant Warning Light If your vehicle has this light, it comes on brieﬂy when you turn your ignition on as a bulb check only. 189 Tire Pressure Light This light should come on brieﬂy as you start the engine. Malfunction Indicator Lamp Check Engine Light Your vehicle has a computer which monitors operation of the fuel, ignition, and emission control systems. This light will also come on when one or more of your tires is signiﬁcantly under-inﬂated. Stop and check your tires as soon as it is safe to do so. If underinﬂated, inﬂate them to the proper pressure. See Tires on page 402 This light will ﬂash for 60 seconds and then turn on solid if a problem is detected with the Tire Pressure Monitor System. See Tire Pressure Monitor System on page 411. 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. 190 If you keep driving your vehicle Notice: with this light on, after awhile, your emission controls may not work as well, your fuel economy may not be as good, and your engine may not run as smoothly. This could lead to costly repairs that may not be covered by your warranty. Notice: Modiﬁcations made to the engine, transaxle, 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 341. This light should come on, as a check to show you it is working, when the ignition is on and the engine is not running. If the light does not come on, have it repaired. This light will also come on during a malfunction in one of two ways: (cid:127) Light Flashing — A misﬁre condition has been detected. A misﬁre increases vehicle emissions and may damage the emission control system on your vehicle. Diagnosis and service may be required. (cid:127) Light On Steady — An emission control system malfunction has been detected on your vehicle. Diagnosis and service may be required. 191 If the Light is Flashing The following may prevent more serious damage to your vehicle: (cid:127) Reducing vehicle speed (cid:127) Avoiding hard accelerations (cid:127) Avoiding steep uphill grades (cid:127) If you are towing a trailer, reduce the amount of cargo being hauled as soon as it is possible If the light stops ﬂashing and remains on steady, see “If the Light Is On Steady” following. If the light continues to ﬂash, when it is safe to do so, stop the vehicle. Find a safe place to park your vehicle. Turn the key off, wait at least 10 seconds and restart the engine. If the light remains on steady, see “If the Light Is On Steady” following. If the light is still ﬂashing, follow the previous steps, and see your dealer for service as soon as possible. If the Light Is On Steady You may be able to correct the emission system malfunction by considering the following: Did you recently put fuel into your vehicle? If so, reinstall the fuel cap, making sure to fully install the cap. See Filling the Tank on page 346. The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap will allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. Did you just drive through a deep puddle of water? If so, your electrical system may be wet. The condition will usually be corrected when the electrical system dries out. A few driving trips should turn the light off. 192 Have you recently changed brands of fuel? If so, be sure to fuel your vehicle with quality fuel. See Gasoline Octane on page 343. 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. Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the check engine light is on or not working properly. Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, your dealer can prepare the vehicle for inspection. 193 Oil Pressure Light Your vehicle may have this feature. {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. If the vehicle has an oil problem, this light may stay on after the engine is started, or come on while you are driving. This light indicates that oil is not going through the engine quickly enough to keep it lubricated. The engine could be low on oil or could have some other oil problem. Have it ﬁxed right away. The oil light could also come on in the following situations: (cid:127) The light will come on brieﬂy when the ignition is turned on to show that it is working properly. If it does not come on with the ignition on, there may be a problem with the fuse or bulb. Have it ﬁxed right away. (cid:127) Sometimes when the engine is idling at a stop, a chime will sound and the light may blink on and off. This is normal. 194 Change Engine Oil Light Security Light If this light comes on, it means that service is required for your vehicle. For information regarding this light, see Theft-Deterrent Systems on page 104. See Scheduled Maintenance on page 462 and Engine Oil on page 353 for more information. After having the oil changed you will need to reset the light. See Engine Oil on page 353 for more information. If this light is blinking, a chime will sound indicating low engine oil. Cruise Control Light This light comes on whenever you set the cruise control. The light goes out when the cruise control is turned off. See Cruise Control on page 154 for more information. 195 Reduced Engine Power Light Highbeam On Light If the reduced engine power light is on, a chime will sound and a noticeable reduction in the vehicle’s performance may occur. This light comes on when the high-beam headlamps are in use. If the reduced engine power light is on, but there is no reduction in performance, proceed to your destination. The performance may be reduced the next time the vehicle is driven. The vehicle may be driven at a reduced speed while the reduced engine power light is on, but acceleration and speed may be reduced. Anytime the reduced engine power light stays on, the vehicle should be taken to an authorized GM dealer as soon as possible for service. See Headlamp High/Low-Beam Changer on page 153. Headlamps Suggested Light This light will come on when the use of headlamps is suggested. 196 Low Washer Fluid Warning Light Trunk Ajar Light This light will come on brieﬂy when the ignition is on. If the light stays on, a chime will sound indicating your windshield washer ﬂuid is low. This light will come on and a chime will sound if the trunk is ajar and the vehicle is not in PARK (P). See Windshield Washer Fluid on page 380 for more information. Try closing the trunk again. Never drive with the trunk open. Door Ajar Light Service Vehicle Soon Light When the ignition is on, this light will stay on until all doors are closed and completely latched. Your vehicle may have this light. You will hear a chime if a door is unlatched after the engine is started and the vehicle is not in PARK (P). It will come on and a chime will sound if it detects a problem on the vehicle. 197 (cid:127) The gage pointer may move while cornering, braking or accelerating. (cid:127) The gage may not indicate empty when the ignition is turned off. Low Fuel Warning Light Your vehicle may have a low fuel light. It is located on the fuel gage and will come on and a chime will sound periodically when the vehicle is low on fuel. The light will go off when fuel is added to the fuel tank. It will also come on for a few seconds when the ignition is turned on as a check to indicate it is working. If it does not come on then, have it ﬁxed. For vehicles with a Driver Information Center (DIC), a LOW FUEL message will appear. See DIC Warnings and Messages on page 208 for more information. Fuel Gage The fuel gage indicates about how much fuel is left in the fuel tank when the ignition is on. When the indicator nears empty, there is still a little fuel left, but you should get more fuel soon. Here are four things that some owners ask about. All these things are normal and do not indicate that anything is wrong with the fuel gage: (cid:127) At the gas station, the pump shuts off before the gage reads full. It takes more, or less, fuel to ﬁll up than the gage reads. For example, the gage reads half full, but it took more, or less, than half of the tank’s capacity to ﬁll it. (cid:127) 198 Check Gas Cap Light Your vehicle may have a check gas cap light. This light will come on and a chime will sound if your gas cap is not securely fastened. See Malfunction Indicator Lamp on page 190 and Filling the Tank on page 346 for more information. Driver Information Center (DIC) Your vehicle may have a Driver Information Center (DIC). All messages will appear in the DIC display located in the instrument panel cluster, below the speedometer. The DIC buttons are located on the center of the instrument panel, below the center outlets. The DIC comes on when the ignition is on. After a short delay, the DIC on the uplevel vehicle will
