How to Check
$.
.:Use a good quality pocket-type gage to check tire
!pressure.
You can’t tell if your tires are properly inflated
lsimply by looking at them. Radial tires may look properly inflated even when they’re underinflated.
@e sure to put
the valve caps back on the valve
’stems. They help prevent leaks by keeping out
dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to. 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your
tires as soon as possible and check
wheel alignment.
Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the myst important.
See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.

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. Mixing
tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires of different sizes may also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
It's
all right to drive with your compact spare,
though.
It was developed for use on your vehicle.
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly, causing a crash. Use only radial-ply
tires with the wheels
on your vehicle.

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.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Pedomance Criteria (PC) standards.
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
I I
(1 1/2) times as well on the government course as a tire ~
graded 100. The relative performance of tires depends 1
upon the actual conditions of their use, however, and
may depart significantly from the nom due to variations
in driving habits, service practices and differences in
road characteristics and climate. ! i
1
Traction -- A, B, C
The traction grades, fkom highest to lowest, are A, B, and
C, and they represent the tire’s ability to stop on wet
pavement
as measured mder controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction perfomce.
Warning: The traction grade assigned to this tire is based
on braking (straight ahead) traction tests and does not
include cornering (turning) traction.

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 retailer or other service
outlets. Larger areas of finish damage can be corrected
in your retailer’s body and paint shop.
Underbody Maintenance Chemical Paint Spotting
Some weather and atmospheric conditions can create
a
chemical fallout. Airborne pollutants can
fall upon and
attack painted surfaces
on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect
in the paint job causes this,
Oldsmobile will repair, at no charge to the owner, the
surfaces of new vehicles damaged by this fallout
condition within
12 months or 12,000 miles (20 000 lun)
of purchase, whichever occurs first.

if you ever need to order parts.
On this label is:
This is the legal identifier for your vehicle. It appears on e your VIN,

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 retailer’s service department or another
qualified service center
do these jobs.
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 skilled enough to do some work on your
vehicle, you will probably want to get the service
information. See “Service and Owner Publications” in
the Index.

Part A: Scheduled Maintenance
Services
Using Your M ’,--lawe 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
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 retailer.
This part tells you the maintenance services you should
have done and when you should schedule them. If you go to your retailer 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 vehicles that:
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.
0 are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
