Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message
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 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 410 for information on the Engine Oil Life
System and resetting the system.
When the CHANGE ENGINE OIL SOON 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.
Maintenance I — Use Maintenance I if the
CHANGE ENGINE OIL SOON message comes on
within 10 months since the vehicle was purchased
or Maintenance
II
was performed.
Maintenance II — Use Maintenance II if the
previous service performed was Maintenance
I
.
Always use Maintenance II whenever 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.
