Normal Vehicle Use

The maintenance instructions contained in this Maintenance Schedule are based on the assumption that the vehicle will be used as designed:

    • To carry passengers and cargo within the recommended limitations as indicated on the Tire Placard located on the edge of the driver's door.
    • On reasonable road surfaces within legal driving limits.
    • On unleaded gasoline of the recommended type. For information on the proper type of fuel to use, refer to the Owner's Manual.

Maintenance Schedule Intervals

The services shown in this schedule up to 166 000 km (100,000 miles) should be performed after 166 000 km (100,000 miles) at the same intervals. The services shown in this schedule to be performed at 240 000 km (150,000 miles) should be performed after 240 000 km (150,000 miles) at the same intervals.

For explanations of the maintenance inspections and services included in this Maintenance Schedule. Refer to Explanation of Scheduled Services .

For additional maintenance inspections and services which are not included in this Maintenance Schedule. Refer to Periodic Maintenance Inspection .

Engine Oil Scheduled Maintenance

Change engine oil and filter as indicated by the GM Oil Life Systemâ„¢ (or every 12 months, whatever occurs first). Reset the indicator. The system will display a message when the oil should be changed -usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the indicator may come on before 5 000 km (3,000 miles). Never drive the vehicle more than 16 000 km (10,000 miles) or 12 months without and oil and filter change. The system will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5 000 km (3,000 miles) or sooner if the CHANGE ENGINE OIL appears on the Drivers Information Center. Reset the Oil Life System when the oil and filter have been changed. Refer to GM Oil Life System Resetting .

Footnotes

[Dagger] The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle's useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.
