Scheduled Maintenance
When the change engine oil message comes on,
it means that service is required for your vehicle.
Have your vehicle serviced as soon as possible within
the next 600 miles (1 000 km). 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 lter 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 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-16for information on
the Engine Oil Life System and resetting the system.When the change engine oil message appears,
certain services, checks, and inspections are required.
Required services are described in the following

recommended that your rst service be MaintenanceI,
your second service be MaintenanceII, and that
you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.

engine oil message comes on within 10 months since
the vehicle was purchased or MaintenanceIIwas
performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
