Simplified Maintenance I and II

2004 GM Cars and Trucks with Gasoline Engines and with GM Oil Life System (OLS)

Required services are described by the terms Maintenance I and Maintenance II. Use Maintenance I if the CHANGE ENGINE OIL light comes on within 10 months of the vehicle purchase or when Maintenance II was the last service performed.

The first service should be Maintenance I; the second should be Maintenance II. Alternate between the two schedules thereafter. Depending upon your driving habits, Maintenance II may be required more often.

Refer to your Owner’s Manual for specific maintenance requirements.

NOTICE: It is important to check your engine oil regularly and keep it at the proper level. Failure to maintain proper oil level can result in expensive engine repairs not covered by the vehicle warranty.

It is important to regularly check your tires for wear and proper inflation. Failure to maintain properly inflated tires can result in premature tire wear, vehicle damage, or personal injury.
