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 DIC message
comes on, it means that service is required
for your vehicle. See
DIC Warnings and Messages
on page 202 . 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, the engine oil
and filter must be changed at least once a year
and at this time the system must be reset.
