When the CHANGE ENGINE OIL light appears, certain services and inspections are required.

Required services are described as Maintenance I and Maintenance II.

The first service on a vehicle should be Maintenance I, and the second service should be Maintenance II.

Alternate between the 2 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 10 months since vehicle was purchased or, if Maintenance II was performed.

Maintenance II: Use Maintenance II if the previous service performed was Maintenance I.

Always use Maintenance II whenever the CHANGE ENGINE OIL light comes on 10 months or more since the last service, or, if the CHANGE ENGINE OIL light has not come on at all for one year.
