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 any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
tire’s rubber.
Buying New Tires
To
find out what kind and size of tires you need, look at
the CertificatiodTire 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.
The tire has a puncture, cut or other damage that
can‘t be repaired well because of the size or location
of the damage.

Treadwear Temperature -- A, B, C
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
graded
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, and 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. The
temperature grades are
A (the highest), B, and C,
representing the tire's resistance to the generation of
heat and its ability
to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire
to degenerate and reduce tire life,
and excessive temperature
can lead to sudden tire
failure. The grade
C corresponds to a level of
performance which all passenger car tires must meet
under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for
a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive
loading, either separately or in combination,
can cause heat buildup and possible tire failure.

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
Chemicals used for ice and snow removal and dust control
can collect on the underbody. If these are not removed,
accelemted corrosion (rust) can occur on the underbody
parts such as fuel lines, frame,
floor pan and exhaust
system even though they have corrosion protection.
At least every spring, flush these materials from the
underbody
with plain water. Clean any areas where mud
and other debris can collect. Dirt packed
in closed areas
of the frame should be loosened before being, flushed.
Your retailer
or an underbody car washing system can
do this for you.
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 de.fect
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 km)
of purchase, whichever occurs first.

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.
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 skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications”
in the Index. “Part
B: Owner Checks and Services”
tells you what
should be checked and when. 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 Oldsmobile retailer’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 Oldsmobile 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:
0 carry passengers and cargo within recommended
limits.
You will find these limits on your vehicle’s
Certification/Tire label. See “Loading Your Vehicle”
in the Index.
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:

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such
as frequent
driving in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One
of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break

Footnotes
7 The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will
not nullify
the emission warranty or limit recall liability prior to the
completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
## Lubricate the front suspension, ball joints, steering
linkage, parking brake cable guides, propshaft splines,
universal joints and brake pedal springs.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection’’ in Part
C of this schedule.
‘b‘k Drive axle service (see “Recommended Fluids and
Lubricants”
in the Index for proper lubricant to usej:
Drain and refill at first oil change. At subsequent oil
changes, check fluid level and add fluid
as needed. If
driving in dusty areas or towing a trailer, drain fluid
and refill every
15,000 miles (25 000 km).
More frequent lubrication may be required for
off-paved-road use.
