For vehicles with a roof rack, the rack can be used to load items. For roof racks that do not have crossrails included, GM Certified crossrails can be purchased as an accessory. See your dealer for additional information.


{ Caution


Loading cargo on the roof rack that weighs more than 91 kg (200 lb) or hangs over the rear or sides of the vehicle may damage the vehicle. Load cargo so that it rests evenly between the crossrails and fasten cargo securely.


To prevent damage or loss of cargo when driving, check to make sure crossrails and cargo are securely fastened. Loading cargo on the roof rack will make the vehicle’s center of gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking, or abrupt maneuvers; otherwise it may result in loss of control. If driving for a long distance, on rough roads, or at high speeds, occasionally stop the vehicle to make sure the cargo remains in its place. Do not exceed the maximum vehicle capacity when loading the vehicle. See Vehicle Load Limits on page 9-9.

are at acceptable levels, helping to maintain a clean environment. The malfunction indicator lamp comes on when the vehicle is placed in ON/RUN, as a check to show it is working. If it does not, have the vehicle serviced by your dealer. See Ignition Positions on page 9-14.


If the malfunction indicator lamp comes on while the engine is running, this indicates that the OBD II system has detected a problem and diagnosis and service might be 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 also


assists the service technician in correctly diagnosing any malfunction.


{ Caution


If the vehicle is continually driven with this light on, the emission controls might not work as well, the vehicle 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.

(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 10-2.


This light may come 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.


If the light continues to flash, find a safe place to stop and 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 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. The following may correct an emission control system malfunction: . Check that the fuel cap is fully


installed. See Filling the Tank on page 9-43. The diagnostic system may be able to determine if the fuel cap has


been left off or improperly installed. A loose or missing fuel cap could allow fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed may turn the light off.


. Check that good quality fuel is used. 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 this occurs, change the fuel brand used. It may require at least one full tank of the proper fuel to turn the light off.


See Fuel on page 9-42. If the light remains on, your dealer can check the vehicle. The dealer has the proper test equipment and


diagnostic tools to fix any mechanical or electrical problems that might have developed. Emissions Inspection and Maintenance Programs Depending on where you live, your vehicle may be required to participate in an emission control system inspection and maintenance program. For the inspection, the emission system test equipment will likely connect to the vehicle's Data Link Connector (DLC).


The DLC is under the instrument panel to the left of the steering wheel. See your dealer if assistance is needed.

The vehicle may not pass inspection if:


The malfunction indicator lamp is on with the engine running, or if the light does not come on when the ignition is turned to ON/RUN while the engine is off. See your dealer for assistance in verifying proper operation of the malfunction indicator lamp. The OBD II (On-Board Diagnostics) system determines that critical emission control systems have not been completely diagnosed. The vehicle would be considered not ready for inspection. This can happen if the 12-volt battery has recently been replaced or 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 can prepare the vehicle for inspection.


Brake System Warning Light The vehicle brake system consists of two hydraulic circuits. If one circuit is not working, the remaining circuit can still work to stop the vehicle. For normal braking performance, both circuits need to be working. If the warning light comes on, there is a brake problem. Have the brake system inspected right away.

or miles (mi). Pressing the trip odometer reset stem will also display the odometer. To switch between English and metric measurements, see “UNITS” earlier in this section.


TRIP A and TRIP B Press the trip/fuel button until TRIP A or TRIP B displays. This display shows the current distance traveled in either kilometers (km) or miles (mi) since the last reset for each trip odometer. Both trip odometers can be used at the same time. Pressing the trip odometer reset stem will also display the trip odometers. Each trip odometer can be reset to zero separately by pressing the set/ reset button or the trip odometer reset stem while the desired trip odometer is displayed. The trip odometer has a feature called retroactive reset. This can be used to set the trip odometer to the number of kilometers (miles) 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 retroactive reset feature, press and hold the set/reset button for at least four seconds. The trip odometer will display the number of kilometers (km) or miles (mi) 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 8 km (5 mi) before it is started again, and then the retroactive reset feature is activated, the display will show 8 km (5 mi). As the vehicle begins moving, the display will then increase to 8.2 km (5.1 mi), 8.4 km (5.2 mi), etc. If the retroactive reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of kilometers (km) or miles (mi) driven during the last ignition cycle.


RANGE Press the trip/fuel button until RANGE displays. This display shows the approximate number of remaining kilometers (km) or miles (mi) 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.
