GM Service Manual Online
For 1990-2009 cars only

The services shown in this schedule up to 120,000 miles (192 000 km) should be repeated after 120,000 miles (192 000 km) at the same intervals for the life of this vehicle.

Footnotes

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 your brakes is during tire rotation. See Brake System Inspection .
