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.
ProCarManuals.com

, Performing maintenance work on a vehicle can
be dangerous.
In trying to do some jobs, you
~ can be seriously injured. Do your own
maintenance work only
if you have the
~ required know-how and the proper tools and
~ equipment for the job. If you have any doubt, I
have a qualified technician do the work.
If you.are skilled enough to do some work on your
vehicle, you will probably want to get the service
information GM publishes.
You will find a list of
publications and how
to get them in this manual. See
“Service Publications” in the Index. “Section
D: Recommended Fluids and Lubricants” lists
some products GM recommends to help keep your
vehicle properly maintained. These products, or their
I equivalents, should be used whether you do the work
yourself or have it done.
“Section
E: Maintenance Record” provides a place for
I ‘you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be sure to write it down in this section. This will help
YOU
determine when your next maintenance should be done.
In addition, it is a
good idea to keep your maintenance .
receipts. They may be needed to qualify your vehicle for
warranty repairs.
“Section
B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It
also
explains what you can easily do to help keep your vehicle
in good condition.
“Section
C: Periodic Maintenance Inspections” explains
iniportant inspections that your Buick dealer’s service
department or another qualified service center should
perform.

costly repairs. Others describe inexpensive repairs
which, if done on time with the latest parts, may avoid
future costly repairs. Some bulletins tell a technician how
to repair a new or unexpected condition. Others describe
a quicker way to fix your vehicle. They can help a
technician service your vehicle better. Most bulletins apply to conditions affecting a small
number of cars
or trucks. Your Buick dealer or a
qualified technician may have to determine
if a specific
bulletin applies to your vehicle.

get them as they come out.
