† 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. GM, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

# Lubricate the front suspension, the ball joints, the steering linkage, the park brake cable guides, and the brake pedal springs.

+ A good time to check your brakes is during tire rotation. Refer to Brake Pad Inspection in Disc Brakes and Brake Shoe Inspection in Drum Brakes.
