{ WARNING

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.

Compass The vehicle may have a compass display on the Driver Information Center (DIC). The compass receives its heading and other information from Global Positioning System (GPS) antenna, StabiliTrak, and vehicle speed information. Avoid covering the GPS antenna for long periods of time with objects that may interfere with the antenna's ability to receive a satellite signal.

See Backglass Antenna on page 6‑19 and Satellite Radio Antenna on page 6‑19 for the location of the vehicle's antennas. The compass system is designed to operate for a certain number of miles or degrees of turn before needing a signal from the GPS satellites. When the compass display shows CAL, drive the vehicle for a short distance in an open area where it can receive a GPS signal. The compass system will automatically determine when GPS signal is restored and provide a heading again. See Compass Messages on page 4‑34 for more information on the messages that may be displayed for the compass.

Power Outlets The accessory power outlets can be used to connect electrical equipment, such as a cellular phone. There are two accessory power outlets, one is located inside the center console storage and other on the rear of the center floor console. Open the protective cover to use the accessory power outlet. Certain electrical accessories may not be compatible with the accessory power outlets and could result in blown vehicle or adapter fuses. If you experience a problem,

see your dealer/retailer for additional information on the accessory power outlet. Notice: Adding any electrical equipment to the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the installation instructions included with the equipment. Notice: Improper use of the power outlet can cause damage not covered by the vehicle 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.

Power Outlet 120 Volt Alternating Current The vehicle may have a power outlet that can be used to plug in electrical equipment that uses a maximum limit of 150 watts.

The power outlet is located on the rear of the center console. An indicator light on the outlet turns on to show it is in use. The light comes on when the ignition is in ON/RUN and equipment requiring less than 150 watts is plugged into the outlet, and no system fault is detected.

Instruments and Controls

4-11

The power outlet is not designed for the following electrical equipment and may not work properly if these items are plugged into the power outlet: . Equipment with high initial peak

wattage such as: compressor-driven refrigerators and electric power tools.

. Other equipment requiring an extremely stable power supply such as: microcomputer-controlled electric blankets, touch sensor lamps, etc.

The indicator light does not come on when the ignition is in LOCK/OFF or if no equipment is plugged into the outlet. If you try to connect equipment using more than 150 watts or a system fault is detected, the equipment may operate for a short period and turn itself off. A protection circuit shuts off the power supply and the indicator light turns off. To reset the circuit, unplug the item and plug it back in or turn the Remote Accessory Power (RAP) off and then back on. See Retained Accessory Power (RAP) on page 8‑20 . Prolonged usage of the power outlet at the maximum load of 150 watts, may cause the outlet to overheat and automatically shutdown. The power restarts when equipment that operates within the limit is plugged into the outlet and a system fault is not detected.

Warning Lights, Gauges, and Indicators Warning lights come on when there could be a problem with a vehicle function. Some warning lights come on briefly when the engine is started to indicate they are working. Gauges can indicate when there could be a problem with a vehicle function. Often gauges and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gauges shows there may be a problem, check the section that explains what to do. Follow this manual's advice. Waiting to do repairs can be costly and even dangerous.

Speedometer The speedometer shows the vehicle's speed in both kilometers per hour (km/h) and miles per hour (mph).

Odometer The odometer shows how far the vehicle has been driven, in either kilometers or miles. This vehicle has a tamper-resistant odometer. If the vehicle needs a new odometer installed, the new one is set to the mileage of the old odometer. If this is not possible, it is set at zero and a label is put on the driver's door to show the old mileage reading.

Tachometer The tachometer displays the engine speed in revolutions per minute (rpm).

Notice: If the engine is operated with the tachometer in the shaded warning area, the vehicle could be damaged, and the damages would not be covered by the vehicle warranty. Do not operate the engine with the tachometer in the shaded warning area.

Fuel Gauge

When the ignition is on, the fuel gauge indicates how much fuel is left in the tank.

An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on. When the indicator nears empty, the low fuel light comes on. There still is a little fuel left, but the fuel tank should filled soon. Here are four things that some owners ask about. None of these show a problem with the fuel gauge: . At the service station, the fuel

pump shuts off before the gauge reads full. It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank. The gauge moves a little while turning a corner or speeding up.

4-14

Instruments and Controls

The gauge takes a few seconds to stabilize after the ignition is turned on, and goes back to empty when the ignition is turned off.

Engine Coolant Temperature Gauge

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 9‑21 for more information.

Safety Belt Reminders

Driver Safety Belt Reminder Light There is a driver safety belt reminder light on the instrument panel cluster.

This gauge shows the engine coolant temperature. If the gauge pointer moves towards the shaded area, the engine is too hot.

When the vehicle is started this light flashes and a chime may come on to remind drivers to fasten their

safety belts. Then the light stays on solid until the belt is buckled. This cycle may continue several times if the driver remains or becomes unbuckled while the vehicle is moving. If the driver safety belt is buckled, neither the light nor chime come on. Passenger Safety Belt Reminder Light

When the vehicle is started this light flashes and a chime comes on to remind passengers to fasten their safety belt. Then the light stays on solid until the belt is buckled. This cycle continues several times if the passenger remains or becomes unbuckled while the vehicle is moving.

If the passenger safety belt is buckled, neither the chime nor the light comes on. The front passenger safety belt warning light and chime may turn on if an object is put on the seat such as a briefcase, handbag, grocery bag, laptop or other electronic device. To turn off the warning light and or chime, remove the object from the seat or buckle the safety belt

Airbag Readiness Light This light shows if there is an electrical problem. The system check includes the airbag sensor, the pretensioners, the airbag modules, the wiring and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System on page 2‑25 .

4-16

Instruments and Controls

If you are using remote start, if equipped, to start the vehicle from a distance you may not see the system check. Then, after several more seconds, the status indicator will light either the word ON or OFF to let you know the status of the right front passenger frontal airbag. If the word ON is lit on the passenger airbag status indicator, it means that the right front passenger frontal airbag is enabled (may inflate). 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 frontal airbag. If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer/retailer for service.

{ WARNING

If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 4‑15 for more information, including important safety information.

Charging System Light

The charging system light comes on briefly when the ignition is turned on, but the engine is not running, as a check to show the light is working.

The light turns off when the engine is started. If it does not, have the vehicle serviced by your dealer/retailer. If the light stays on, or comes on while driving, there could be a problem with the electrical charging system. Have it checked by your dealer/retailer. Driving while this light is on could drain the battery. This light and a Transport On message display when the vehicle is in Transport Mode. For more information, see Key and Lock Messages on page 4‑36. If a short distance must be driven with the light on, be sure to turn off all accessories, such as the radio and air conditioner.

Instruments and Controls

Malfunction Indicator Lamp A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It ensures that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment.

This light comes on when the ignition is on, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer/retailer.

If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction. Notice: If the vehicle is continually driven with this light on, after a while, the emission controls might not work as well, the vehicle's fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty.

Notice: Modifications made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle's emission controls and can cause this light to come on. Modifications to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modifications on page 9‑3. This light comes on during a malfunction in one of two ways: Light Flashing: A misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Diagnosis and service might be required.

4-18

Instruments and Controls

The following can prevent more serious damage to the vehicle: . Reduce vehicle speed. . Avoid hard accelerations. . Avoid steep uphill grades.

If towing a trailer, reduce the amount of cargo being hauled as soon as it is possible.

If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the vehicle off, wait at least 10 seconds, and restart the engine. If the light is still flashing, follow the previous steps and see your dealer/retailer for service as soon as possible. Light On Steady: An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required.

An emission system malfunction might be corrected. . Make sure the fuel cap is fully

installed. See Filling the Tank on page 8‑52 . The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off. If the vehicle has been driven through a deep puddle of water, the vehicle's electrical system might be wet. The condition is usually corrected when the electrical system dries out. A few driving trips should turn the light off.

. Make sure to fuel the vehicle

with quality fuel. Poor fuel quality causes the engine not to run as efficiently as designed and may cause: stalling after start-up, stalling when the vehicle is changed into gear, misfiring, hesitation on acceleration, or stumbling on acceleration. These conditions might go away once the engine is warmed up. If one or more of these conditions occurs, change the fuel brand used. It will require at least one full tank of the proper fuel to turn the light off. See Gasoline Specifications on page 8‑49 .

If none of the above have made the light turn off, your dealer/retailer can check the vehicle. The dealer/ retailer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that might have developed.

Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection:

The vehicle will not pass this inspection if the check engine light is on with the engine running, or if the ignition is placed in ON/RUN and the light is not on.

The vehicle will not pass this inspection if the OBD II (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 the battery has recently been replaced or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer/ retailer can prepare the vehicle for inspection.

Brake System Warning Light The vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking both parts need to working. If the warning light comes on, there is a brake problem. Have your brake system inspected right away.

If the vehicle has antilock brakes, this light should come on when the key is placed in START. If it does not, have the vehicle serviced by your dealer/retailer.

4-20

Instruments and Controls

If the light comes on while driving, pull off the road and stop carefully. The pedal may be harder to push or it can go closer to the floor. It may take longer to stop. Try turning off and restarting the vehicle one or two times, if the light is still on, have the vehicle towed for service. See Antilock Brake System (ABS) Warning Light on page 4‑21 and Towing the Vehicle on page 9‑81.

{ WARNING

The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service.

Electric Parking Brake Light

For vehicles with the Electric Park Brake (EPB), the park brake status light comes on when the brake is applied. If the light continues flashing after the park brake is released, or while driving, there is a problem with the Electric Parking Brake system. A Service Parking Brake message can also display in the Driver Information Center (DIC). See Brake System Messages on page 4‑33 for more information. If the light does not come on, or remains flashing, see your dealer/retailer.

For vehicles with the Electric Park Brake (EPB), the park brake warning light should come on briefly when ignition is placed in ON/RUN. If it does not come on, then have it fixed so it will be ready to warn if there is a problem. If this light comes on, there is a problem with a system on the vehicle that is causing the park brake system to work at a reduced level. The vehicle can still be driven, but should be taken to a dealer/ retailer as soon as possible. See Parking Brake on page 8‑32 for more information. For vehicles with the uplevel cluster, this telltale displays in the Driver Information Center (DIC) screen.

Antilock Brake System (ABS) Warning Light

This light comes on briefly when the engine is started. If the light does not come on, have it fixed so it will be ready to warn if there is a problem. If the ABS light stays on, turn the ignition off. If the light comes on while driving, stop as soon as it is safely possible and turn off the vehicle.

Then start the engine again to reset the system. If the ABS light stays on, or comes on again while driving, the vehicle needs service. A chime may also sound when the light comes on steady. If the ABS light is the only light on, the vehicle has regular brakes, but the antilock brakes are not functioning. If both lights are on, the vehicle's antilock brakes are not functioning and there is a problem with the regular brakes. See your dealer/ retailer for service. See Brake System Warning Light on page 4‑19 . See Brake System Messages on page 4‑33 for all brake related DIC messages.

Traction Off Light

This light comes on when the Traction Control System (TCS) has been turned off by pressing and releasing the traction control button. This light also comes on and the system turns off if there is a problem with the traction control system. If the light comes on and stays on for an extended period of time while the system is turned on, the vehicle needs service.

Head-Up Display (HUD)

{ WARNING

If the HUD image is too bright or too high in your field of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the HUD image dim and placed low in your field of view.

For vehicles with the Head-Up Display (HUD), some information concerning the operation of the vehicle is projected onto the windshield. This includes the speedometer reading, RPM reading, transmission position, outside air temperature, compass heading and a brief display of the current radio station, including XM information or CD track. It will also display turn-by-turn navigation information if the vehicle has a navigation radio.

The images are projected through the HUD lens located on the driver's side of the instrument panel. Notice: If you try to use the HUD image as a parking aid, you may misjudge the distance and damage your vehicle. Do not use the HUD image as a parking aid. The tap shift gear will also appear on the HUD if the vehicle has tap shift and it is active. The HUD information can be displayed in one of three languages, English, French, or Spanish. The speedometer reading and other numerical values can be displayed in either English or metric units. The language selection is changed through the radio and the units of measurement is changed through the trip computer in the Driver Information Center (DIC). See AM-FM Radio on page 6‑12 and Driver Information Center (DIC) on page 4‑25 .

Format Two: This display includes the information in Format One without the transmission information, the outside air temperature, and compass heading.

Format Three: This display includes all the information in Format One along with a circular tachometer, but without outside air temperature and compass heading. All formats will show the turn-by-turn navigation information and provide details about the next driving maneuver to be made. When you near your destination, the HUD will display a distance bar that will empty the closer you get to your destination.

4-32

Instruments and Controls

All navigation information is provided to the HUD by the navigation radio or OnStar® service, for vehicles that have these features.

The HUD image displayed on the windshield will automatically dim and brighten to compensate for outside lighting. However, the HUD brightness control can still be adjusted as needed.

The HUD image can temporarily light up depending on the angle and position of the sunlight on the HUD display. This is normal and will change when the angle of the sunlight on the HUD display changes. Polarized sunglasses could make the HUD image harder to see. Care of the HUD Clean the inside of the windshield as needed to remove any dirt or film that could reduce the sharpness or clarity of the HUD image. To clean the HUD lens, use a soft, clean cloth that has household glass cleaner sprayed on it. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens because the cleaner could leak into the unit.

If You Cannot See the HUD Image When the Ignition Is On

Is anything covering the HUD lens? Is the HUD dimmer setting bright enough? Is the HUD image adjusted to the proper height?

. Are you wearing polarized

sunglasses?

. Still no HUD image? Check the

fuse in the instrument panel fuse block. See Instrument Panel Fuse Block on page 9‑44.

If the HUD Image Is Not Clear

Is the HUD image too bright? . Are the windshield and HUD

lens clean?

If the HUD image is not correct, contact your dealer/retailer. Keep in mind that the windshield is part of the HUD system.
