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,
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.

Downloaded from www.Manualslib.com manuals search engine 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
Performance Criteria
(TPC) standards.
eadwear
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 haIf
( 1 1/2) times as well on the government course as a tire
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
b Oraded 100. The relative performance of tires depends in
driving habits, service practices and differences in
road characteristics and climate.
action -- A9
The traction grades, from highest to lowest, are A, €3 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 (straightahead) traction tests and does not
include cornering (turning) traction.
~~~~~~~~~~~ -ID A?
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
A and B represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Page 307 of 361

Downloaded from www.Manualslib.com manuals search engine 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.
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest
tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear
or
your vehicle pulling one way or the other, the alignment
may need to be reset.
If you notice your vehicle
vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Replace any
wheel that is bent, cracked or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If the
wheel leaks air, replace
it (except some aluminum
wheels, which can sometimes be repaired). See
your
Cadillac dealer if any of these conditions exist. Your
dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way
as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This
way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your
Cadillac model.
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous. It
could affect the braking and
handling
sf your vehicle, make your tires lose air
and make
YOU lose control. You could have a
c~llision in which you or others could be injured.
Always
use the correct wheel, wheel boats and
wheel nuts for replagment.

Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl or leather with a clean, damp cloth.
Your Cadillac dealer has two 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:
1. Always read the instructions on the cleaner label.
2. Clean up stains as soon as you can -- before they set.
3. Use a clean cloth or sponge, and change to a clean area
often.
A soft brush may be used if stains are stubborn.
4. Use solvent-type cleaners in a well-ventilated area
only.
If you use them, don’t saturate the stained area.
5. If a ring forms after spot cleaning, clean the entire
area immediately or it will set.

First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean
off better with just
water and mild soap.
If you need to use a solvent:
1. Gently scrape excess soil from the trim material with
a clean, dull knife
or scraper.
2. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the
outside of the stain, “feathering” toward the center.
3. Keep changing to a clean section of the cloth.
4. When you clean a stain from fabric, immediately dry the
area with a blow dryer to help prevent a cleaning ring.
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed
as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left
on a vehicle’s seat fabric. They should
be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause
them to spread.
