Owner Checks and Services on page 6-9 tells you what
should be checked, when to check it and what you can
easily do to help keep your vehicle in good condition.
The proper replacement parts, fluids and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 6-12 and Normal Maintenance Replacement
Parts on page 6-14. 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 OIL light 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 5-16 for information on the Engine Oil
Life System and resetting the system.
When the CHANGE OIL light 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
OIL light 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 light comes on 10 months
or more since the last service or if the light has not
come on at all for one year.
