When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine GM parts.Scheduled Maintenance
When the change engine oil light or CHANGE
ENGINE OIL DIC message comes on, it means
that service is required for your vehicle. See
Change Engine Oil Light on page 214orDIC
Warnings and Messages on page 222. 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.
507

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 398for information on the Engine Oil Life
System and resetting the system.
When the change engine oil light or CHANGE
ENGINE OIL DIC 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 MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay
be required more often.MaintenanceI— Use MaintenanceIif the light
or 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 light
or message comes on 10 months or more since
the last service or if the light or message has
not come on at all for one year.
