For 1990-2009 cars only

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 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

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 emissions 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.

+ A good time to check the brakes is during tire rotation. Refer to Brake Pad Inspection in Disc Brakes.

Engine Oil Scheduled Maintenance

Change engine oil and filter as indicated by the GM Oil Life Systemâ„¢ ( or every 12  months, whichever occurs first). Reset the system. The system will show you when to change the oil - usually between 5 000 km (3,000 mi) and 16 000 km (10,000 mi) since the last oil change. Under severe conditions, the CHANGE OIL SOON message may be displayed before 5 000 km (3,000 mi).

The vehicle MUST NOT be driven more than 16 000 km (10,000 mi) or 12 months without an oil and filter change. Use engine oil meeting the GM Standard GM 4718M.

The system will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil and filter every 5 000 km (3,000 mi) or sooner if the CHANGE OIL SOON message is displayed. Reset the Oil Life System when the oil and filter have been changed. Refer to GM Oil Life System Resetting .
