Required services are described by the term 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. Depending upon your driving habits, Maintenance II may be required more often. Never drive your vehicle more than 12 months without oil and filter change. You should have the engine oil changed within 600 miles after the light comes on. 

 

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