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 lmow 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.
288
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.
CAUTION
A
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, have
a qualified technician do the work.
-
If you are skilk- xough 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.

WHAT SHOULD BE DONE
Inspect the front and rear suspension and steering system for damaged, loose or missing parts,
signs of wear,

hookup, binding, leaks, cracks, chafing, etc. Clean and then in\
spect the drive axle boot seals for
damage, tears or leakage. Replace seals if necessary.
Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken,
damaged, missing or out-of-position parts as well as open seams, holes, loose connections, or
other conditions which could cause a heat build-up
in the floor pan or could let exhaust fumes
into the vehicle. See the
Index under Engine Exhaust.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed.
Inspect the complete system. Inspect brake lines and hoses for proper hooku\
p, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect
other brake parts, including calipers, parking brake, etc. Check parking brake adjustment. You
may need to have your brakes inspected more often if your driving habits or conditions result in
frequent braking.
Note: A low brake fluid level can indicate worn disc brake pads which may need to be serviced.
Also, if the brake system warning light stays on or comes on, something may be wrong with the
brake system. See the
Idex under Brake System Warning Light. If your vehicle is equipped with
anti-lock brakes and the anti-lock brake system warning light stays on, comes on or flashes,
something may be wrong with the anti-lock brake system. See the
