Owner Checks and Services on page6-8 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 page6-11 and Normal Maintenance Replacement
Parts on page6-13. 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 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 3,000miles
(5000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page5-18 for information on
the Engine Oil Life System and resetting the system.
When the CHANGE OIL SOON message appears,
certain services, checks and inspections are required.
Required services are described in the following for
“MaintenanceI” and “Maintenance II.” Generally,
it is recommended that your first service be
MaintenanceI, your second service be Maintenance II
and that you alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceII
may be required more often.
MaintenanceI— Use Maintenance Iif the message
comes on within 10 months since the vehicle was
purchased or MaintenanceII was performed.
MaintenanceII — Use Maintenance II if the previous
service performed was MaintenanceI. Always use
MaintenanceII 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.
