When the CHANGE ENGINE OIL light comes on, it means that service is required for your vehicle. Have your vehicle serviced as soon as possible within the next 1,000 km (600 mi). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. Your GM Goodwrench dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system.
If the engine oil life system is ever reset accidentally, you must service your vehicle within 5,000 km (3,000 mi) since your last service. Remember to reset the oil life system whenever the oil is changed. Refer to GM Oil Life System Resetting for information on the engine Oil Life System and resetting the system.
When the CHANGE ENGINE OIL light appears, certain services, checks and inspections are required. Required services are described in the following for Maintenance I and Maintenance II. Generally, it is recommended that your first service be Maintenance I, your second service be Maintenance II and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often.
Maintenance I -- Use Maintenance I if the CHANGE ENGINE OIL light comes on within ten months since vehicle was purchased or Maintenance II was performed.
Maintenance II -- Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the light comes on ten months or more since the last service or if the light has not come on at all for one year.
