Scheduled Maintenance
When the Change Oil Soon message in the Driver
Information Center (DIC) 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 5-18for information on
the Engine Oil Life System and resetting the system.When the Change Oil Soon message appears, certain
services, checks, and inspections are required.
Required services are described in the following for
“MaintenanceI” and “MaintenanceII.” Generally,
it is 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.
MaintenanceI— Use MaintenanceIif the 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
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
