Maintenance Schedule
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 Pontiac 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.
Performing maintenance work on a vehicle can be
3 dangerous. In trying to do some jobs, you can be
.-' wsly injured. Do your own maintenance work
UIUY if you have the required know-how and the proper
tools and equipment for the job. If
you have any doubt,
have a qualified technician do the work.
I
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 the
Index under Service
Publications.
Section B: Owner Checks & 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
important inspections that your Pontiac dealer's service
department or another qualified service center should
perform.
Section
D: Recommended Fluids & 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.
Section
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 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.

Maintenance Schedule
Section A: Scheduled Maintenance Services
Using Your Maintenance Schedules
This section tells you the maintenance services you should
have done and when you should schedule them. Your
Pontiac dealer knows your vehicle best and wants you
to be
happy with it. 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.
These schedules are for vehicles that:
carry passengers anti cargo within recommended limits.
You will find these limits
on your vehicle’s Tire-Loading
Information label. See the
