Introduction
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 Section is Organized
The remainder of this section is divided into five parts:
“Part 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.
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.
“Part 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.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform.
“Part D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do
the work
yourself or have it done.
“Part E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance
is performed, be
sure to write
it down in this part. 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.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
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’ll find
in the schedules in this section.
So please read this
section and note how you drive.
If you have any
questions on how to keep your vehicle in good
condition, see your Buick dealer.
This part tells you the maintenance services you should
have done and when you should schedule them.
If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts. The
proper fluids and lubricants to use
are listed in
Part
D. Make sure whoever services your vehicle uses
these. All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
These schedules are for vehxles that:
