Scheduled Maintenance
When the CHANGE OIL NOW 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. SeeEngine Oil Life
System on page 6-16for information on the Engine Oil
Life System and resetting the system.When the CHANGE OIL NOW 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 CHANGE
OIL NOW 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.
