If you want to purchase service information, see Service
Publications Ordering Information on page 7-17.
Owner Checks and Services on page 6-8 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 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 SOON message in the
Driver Information Center (DIC) comes on, it means
that service is required for your vehicle. See DIC
Warnings and Messages on page 3-40. 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 5-20 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 “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 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 CHANGE OIL SOON
message comes on 10 months or more since the last
service or if the message has not come on at all for
one year.
