Introduction
A Word,About Maintenance
We at General Motors want to help you keep your vehicle
in good working condition. But we don’t know exactly
how you’ll drive it. You may drive very short distances
only a few times a week. Or you may drive long
distances all the time in very hot, dusty weather. You
may use. your vehicle
in making deliveries. Or you may
drive it to work, to do errands or in many other ways.
Because of all the different ways people use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than you will
find
in the schedules in this part. So please read this part
and note how you drive.
If you have any questions on
how to keep your vehicle in good condition, see your
Buick dealer, the place many GM owners choose to have
their maintenance work done. Your dealer can be relied
upon to use proper parts and practices.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but
also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal
of important components can significantly affect
the quality
of the air we breathe. Improper fluid levels or
even the wrong tire inflation can increase the level of
emissions from your vehicle. To help protect our
environment, and to help keep your vehicle in
good
condition, please maintain your vehicle properly.
How This Part is Organized
The remainder of this part is divided into five sections:
“Section
A: Scheduled Maintenance Services” shows
what to have done and how often. Some
of these services
can
be complex, so unless you are technically qualified
and have the necessary equipment, you should let your
dealer’s service department or another qualified service
center do these
jobs.
