Scheduled Maintenance
When the CHANGE OIL message comes on, it
means that service is required for your vehicle. See
DIC Warnings and Messages on page 200 . 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 filter 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 336 for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL message appears, certain
services, checks, and inspections are required.
Required services are described in the following
for “Maintenance
I ” and “Maintenance II .”
Generally, it is recommended that your first
service be Maintenance
I , your second service
be Maintenance
II
, and that you alternate
Maintenance I and Maintenance II thereafter.
However, in some cases, Maintenance II may
be required more often.
