When it’s Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less
of tread remaining.
You need a new tire if:
0 You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the tire’s
rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough
to show cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get
ones with that same TPC Spec number. That way,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle. If your tires have an all-season tread
design, the TPC number will be followed by an
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance.
(This applies only
to vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on
a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
c- qraded 100. The relative performance of tires depends
upon the actual conditions
of their use, however, and
may depart significantly from the norm due
to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s ability to stop on wet
pavement
as measured under controlled conditions on
specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based
on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.

Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years.
You can help to keep the paint finish looking
new by keeping your Buick garaged or covered
whenever possible.
Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar
to
the painted surface of your vehicle. Don’t use strong
soaps, chemicals, chrome polish, abrasive cleaners or
abrasive cleaning brushes on them because you could
damage this coating. After rinsing thoroughly,
a wax
may be applied.
NOTICE:
If you have aluminum wheels, don’t use an
automatic car wash that has hard silicon carbide
cleaning brushes. These brushes can take the
protective coating
off your aluminum wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
When applying
a tire dressing always take care to wipe
off any overspray or splash from painted surfaces.
Petroleum-based products may damage the paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced
to restore corrosion protection.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal
will corrode
quickly and may develop into
a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.

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:
0
0
0
carry passengers and cargo within recommended
limits. You will find these limits
on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended unleaded fuel. See “Fuel” in
the Index.
