i TREAD WEAR INDICATORS
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 you.

or snagged deep enough to show cord
or fabric.
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 Certification/Tire
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
a “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. Iz

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 %)
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. 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.
Temperature-A, B, C
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.
These grades are molded
on the
sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General
Motors performance standards and

Tire Chains
NOTICE:
Use tire chains only where legal and
only when you must. Use only SAE
Class
“S” type chains that are the
proper size for your tires. Install
them on the front tires and tighten
them as tightly as possible with the
ends securely fastened. Drive
slowly and follow the chain
manufacturer’s instructions. If you
can hear the chains contacting your
vehicle, stop and retighten them,
If
the contact continues, slow down
until it stops. Driving too fast with
chains on will damage your vehicle.
Appearance Care
Remember, cleaning products can be
hazardous. Some are toxic. Others can
burst into flame if you strike
a match or
get them on a hot part
of the vehicle.
Some are dangerous
if you breathe their
fumes in a closed space. When you use
anything from a container to clean your
Oldsmobile, be sure to follow the
manufacturer’s warnings and instructions.
And always open your
doors or windows when you’re cleanin,
the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous
- some
more than others
- and they can all
damage your vehicle, too.
NOTICE:
Don’t use any of these unless this
manual says you can. In many uses,
these will damage
your vehicle:
Laundry Soap
Bleach
Reducing Agents
Cleaning the Inside of Your
Oldsmobile
Use a vacuum cleaner often to get rid of
dust and loose dirt. Wipe vinyl or
leather with a clean, damp cloth.
Your Oldsmobile dealer has two
GM
cleaners, a solvent-type spot lifter and a
foam-type powdered cleaner. They will
clean normal spots and stains very well.
Do not use them on vinyl or leather.
Here are some cleaning tips:
Always read the instructions on the
cleaner label.
Clean up stains as soon as you can - I
before they set.
Use a clean cloth or sponge, and
change to
a clean area often. A soft
brush may be used
if stains are
stubborn.
Use solvent-type cleaners in a well-
ventilated area only. If you use them,
don’t saturate the stained area.
If a ring forms after spot cleaning,
clean the entire area immediately or it
will set.

type instructions described earlier.
If an odor lingers after cleaning vomit
or urine, treat the area with a

off quickly. Use a clean cloth and a
solvent-type vinyl cleaner.
Cleaning Leather
Use a soft cloth with lukewarm water
and a mild soap or saddle soap.
For stubborn stains, use a mild
solution of
10% isopropyl alcohol
(rubbing alcohol) and
90% water.
Never use oils, varnishes, solvent-
based or abrasive cleaners, furniture
polish or shoe polish on leather.
Soiled leather should be cleaned
immediately.
If dirt is allowed to work
into finish, it can harm the leather.
Cleaning the Top of the
Instrument Panel
Use only mild soap and water to clean
the top surfaces
of the instrument
panel. Sprays containing silicones
or
waxes may cause annoying reflections
in the windshield and even make it
difficult to see through the windshield
under certain conditions. Vacuum
the carpeted area as needed,
and clean as you would any other
carpet.
Care of Safety Belts
Keep belts clean and dry.

Finish Care
Occasional waxing or mild polishing of
your Oldsmobile may be necessary to
remove residue from the paint finish.
You can get GM approved cleaning
products from your dealer.
Your Oldsmobile has
a
“basecoat/clearcoat” paint finish. The
clearcoat gives more depth and gloss to
the colored basecoat. Always use waxes
and polishes that are non-abrasive and
made for
a basecoat/clearcoat paint
finish.
NOTICE:
Machine compounding or
aggressive polishing on a
basecoat/clearcoat paint finish may
dull the finish or leave swirl marks.
UAluminum Week
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:
Don’t use an automatic vehicle
wash that has hard silicon carbide
cleaning brushes. These brushes
can take off the protective coating.
I Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better, and
not stick or squeak. Apply silicone
grease with a clean cloth at least every
six months. During very cold, damp
weather more frequent application may
be required. (See
Recommended Fluids
G- Lubricants in the Index.)
Foreigpt Material
Calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, and other foreign
matter can damage your vehicle’s finish
if they remain on painted surfaces. Use
cleaners that are marked safe for
painted surfaces to remove foreign
matter.
I Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired right away.
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.

Headlight Wiring
The headlight wiring is protected by a
circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off: or
in some cases to
remain off. If this happens, have your
headlight system checked right away.
Windshield Wipers
The windshield wiper motor is
protected by a circuit breaker and a
fuse.
If the motor overheats due to
heavy snow, etc., the wiper will stop
until the motor cools.
If the overload is
caused by some electrical problem, have
it fixed.
Power Windows and Other Power
Options
Circuit breakers in the circuit
breakerhelay panel protect the power
windows and other power accessories.
When the current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the problem
is fixed.
