Sensors


The solar sensor, located in the defrost grille, in the middle of the instrument panel, monitors the solar heat. Do not cover the solar sensor or the system will not work properly.


The interior temperature sensor, located in the headliner, measures the temperature of the air inside the vehicle.


There is also an exterior temperature sensor located behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false reading in the displayed temperature. The climate control system uses the information from these sensors to maintain your comfort setting by adjusting the outlet temperature, fan speed, and the air delivery mode. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures.


4-27


Outlet Adjustment Use the air outlets located in the center and on the side of the instrument panel to direct the airflow. Use the thumbwheels near the air outlets to open or close off the airflow. Operation Tips . Clear away any ice, snow, or leaves from air inlets


at the base of the windshield that could block the flow of air into the vehicle.


. Keep the path under the front seats clear of


objects to help circulate the air inside of the vehicle more effectively.


. Use of non‐GM approved hood deflectors can


adversely affect the performance of the system. Check with your dealer/retailer before adding equipment to the outside of the vehicle.


Warning Lights, Gages, and Indicators 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 prevent injury. Warning lights come on when there might be or there is a problem with one of the vehicle's functions. Some warning lights come on briefly when the engine is started to indicate they are working. Gages can indicate when there might be or there is a problem with one of the vehicle's functions. Often gages 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 gages shows there could 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.

Charging System Light


Voltmeter Gage


This light comes on briefly when the ignition key is turned to START, but the engine is not running, as a check to show it is working.


For vehicles with a voltmeter gage, this gage indicates the battery voltage when the ignition is turned on.


If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear. See DIC Warnings and Messages on page 4‑63 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner.


When the ignition is on, this gage indicates the battery voltage. When the engine is running, this gage shows the condition of the charging system. The gage can transition from a higher to lower or a lower to higher reading. This is normal. If the vehicle is operating outside the normal operating range, the charging system light comes on. See Charging System Light on page 4‑36 for more information. The voltmeter gage may also read lower when in fuel economy mode. This is normal.


4-36


Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. The vehicle can only be driven for a short time with the readings outside the normal operating range. If the vehicle must be driven, turn off all accessories, such as the radio and air conditioner. Readings outside the normal operating range indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible.


Brake System Warning Light With the ignition on, the brake system warning light comes on when the parking brake is set. If the vehicle is driven with the parking brake engaged, a chime sounds when the vehicle speed is greater than 5 mph (8 km/h). 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 be working well. If the warning light comes on and a chime sounds there could be a brake problem. Have the brake system inspected right away. This light can also come on due to low brake fluid. See Brakes on page 6‑39 for more information.


4-37


If the light comes on while driving, pull off the road and stop carefully. The pedal might be harder to push or might go closer to the floor. It can take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 5‑43. Antilock Brake System (ABS) Warning Light

If it does not, have the vehicle serviced by your dealer/ retailer. If the system is working normally the indicator light then goes off.


United States


Canada


This light comes on briefly when the ignition key is turned to ON/RUN. If it does not come on then, have it fixed so it is ready to warn if there is a problem.


{ 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.


4-38


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 the ignition off. 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. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 4‑37. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 4‑63 for all brake related DIC messages.


StabiliTrak® Indicator Light


For vehicles with the StabiliTrak® system, this light comes on briefly while starting the engine.


If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the light comes on and stays on while driving, there could be a problem with the StabiliTrak® system and the vehicle might need service. When this warning light is on, the StabiliTrak® system is off and does not limit wheel spin. The light flashes if the system is active and is working to assist the driver with directional control of the vehicle in difficult driving conditions. See StabiliTrak® System on page 5‑6 for more information.


4-39


Engine Coolant Temperature Gage


Tire Pressure Light


For vehicles with a tire pressure monitoring system, this light comes on briefly when the engine is started. It provides information about tire pressures and the Tire Pressure Monitoring System. When the Light is On Steady This indicates that one or more of the tires is significantly underinflated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See Driver Information Center (DIC) on page 4‑49 for more information. Stop and check the tires as soon as it is safe to do so. If underinflated, inflate to the proper pressure. See Inflation - Tire Pressure on page 6‑72
for more information.


United States


Canada


This gage shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If the vehicle is pulling a load or going up hills, it is normal for the temperature to fluctuate and go over the 235°F (113°C) mark. However, if the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 6‑34.


4-40


When the Light Flashes First and Then is On Steady This indicates that there may be a problem with the Tire Pressure Monitor System. The light flashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor Operation on page 6‑76 for more information. Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It ensures that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment.


This light should come 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.


4-41


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 key 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 by doing the following:


. Make sure the fuel cap is fully installed. See Filling


the Tank on page 6‑11 . 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.


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 6‑4. 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. To 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.


4-42


.


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 can 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 Octane on page 6‑7.


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 key is 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.

A reading outside the normal operating range can be caused by a dangerously low oil level or some other problem causing low oil pressure. Check the vehicle's oil as soon as possible. See “OIL PRESSURE LOW” under DIC Warnings and Messages on page 4‑63 and Engine Oil on page 6‑18.


{ WARNING:


Do not keep driving if the oil pressure is low. The engine can become so hot that it catches fire. Someone could be burned. Check the oil as soon as possible and have the vehicle serviced.


Notice: Lack of proper engine oil maintenance can damage the engine. The repairs would not be covered by the vehicle warranty. Always follow the maintenance schedule in this manual for changing engine oil.

V (Set/Reset): Press this button to set or reset certain functions and to turn off or acknowledge messages on the DIC. Trip/Fuel Menu Items 3 (Trip/Fuel): Press this button to scroll through the following menu items: Odometer Press the trip/fuel button until ODOMETER displays. This display shows the distance the vehicle has been driven in either miles (mi) or kilometers (km). Pressing the trip odometer reset stem will also display the odometer. To switch between English and metric measurements, see “Units” later in this section.


Trip Odometer Press the trip/fuel button until TRIP displays. This display shows the current distance traveled in either miles (mi) or kilometers (km) since the last reset for the trip odometer. Pressing the trip odometer reset stem will also display the trip odometer. The trip odometer can be reset to zero by pressing the set/reset button while the trip odometer is displayed. You can also reset the trip odometer while it is displayed by pressing and holding the trip odometer reset stem. The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of miles (kilometers) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold the set/reset button for at least four seconds. The trip odometer will display the number of miles (mi) or kilometers (km) driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 5 miles (8 km) before it is started again, and then the retro-active reset feature is activated, the display will show 5 miles (8 km). As the vehicle begins moving, the display will then increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.


Fuel Range Press the trip/fuel button until FUEL RANGE displays. This display shows the approximate number of remaining miles (mi) or kilometers (km) the vehicle can be driven without refueling. The display will show LOW if the fuel level is low. The fuel range estimate is based on an average of the vehicle's fuel economy over recent driving history and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this display may read one number, but if the vehicle is driven on a freeway, the number may change even though the same amount of fuel is in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. Fuel range cannot be reset. Average Economy Press the trip/fuel button until AVG ECONOMY displays. This display shows the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number is calculated based on the number of mpg (L/100 km) recorded since the last time this menu item was reset. To reset AVG ECONOMY, press and hold the set/reset button.

DIC Compass Your vehicle may have a compass in the Driver Information Center (DIC). Compass Zone The zone is set to zone eight upon leaving the factory. Your dealer/retailer will set the correct zone for your location. Under certain circumstances, such as during a long distance cross-country trip or moving to a new state or province, it will be necessary to compensate for compass variance by resetting the zone through the DIC if the zone is not set correctly.


Compass variance is the difference between the earth's magnetic north and true geographic north. If the compass is not set to the zone where you live, the compass may give false readings. The compass must be set to the variance zone in which the vehicle is traveling. To adjust for compass variance, use the following procedure: Compass Variance (Zone) Procedure


1. Do not set the compass zone when the vehicle is moving. Only set it when the vehicle is in P (Park). Press the vehicle information button until PRESS V TO CHANGE COMPASS ZONE displays. Or, if the vehicle does not have DIC buttons, press the trip odometer reset stem until CHANGE COMPASS ZONE displays.

Compass Calibration The compass can be manually calibrated. Only calibrate the compass in a magnetically clean and safe location, such as an open parking lot, where driving the vehicle in circles is not a danger. It is suggested to calibrate away from tall buildings, utility wires, manhole covers, or other industrial structures, if possible. If CAL should ever appear in the DIC display, the compass should be calibrated. If the DIC display does not show a heading, for example, N for North, or the heading does not change after making turns, there may be a strong magnetic field interfering with the compass. Such interference may be caused by a magnetic CB or cell phone antenna mount, a magnetic emergency light, magnetic note pad holder, or any other magnetic item. Turn off the vehicle, move the magnetic item, then turn on the vehicle and calibrate the compass.


To calibrate the compass, use the following procedure: Compass Calibration Procedure


1. Before calibrating the compass, make sure the


compass zone is set to the variance zone in which the vehicle is located. See “Compass Variance (Zone) Procedure” earlier in this section. Do not operate any switches such as window, sunroof, climate controls, seats, etc. during the calibration procedure.


2. Press the vehicle information button until


PRESS V TO CALIBRATE COMPASS displays. Or, if the vehicle does not have DIC buttons, press the trip odometer reset stem until CALIBRATE COMPASS displays.
