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.

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.

(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)
