1994 CADILLAC SEVILLE Owners Manual

Downloaded from www.Manualslib.com manuals search engine The STS tire pressures are:
Front - 29 psi (200 kPa)
Rear - 29 psi (200 kPa)
STS recommended tire size is:
Eagle GA (2-Rated) Blackwall (P225/60ZR16)
Don’t forget your compact spare tire. It should be at 60 psi
(420 kPa).
Tire Inspection and Rotation
To make your tires last longer, have them inspected and rotated at the
mileages recommended
in the Maintenance Schedule. See “Scheduled
Maintenance Services”
in the Index.
Use this rotation
pattern.
After the tires have been rotated, adjust the front and rear inflation
pressure as shown
on the Tire-Loading Information label. Make certain
that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the
Index.

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
2/32 inch
(1.6 mm) or less of
tread remaining.
You need
a new tire if:
You can see the indicators at three or more places around the tire.
You can see cord or fabric showing through the tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep enough to show
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other damage that can’t be repaired

or fabric.
well because of the size or location of the damage.

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 yowget 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.
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.)

Downloaded from www.Manualslib.com manuals search engine 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 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
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.
-. - tire’s resistance to the generation of heat and its ability to dissipate heat
_- -
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.

Downloaded from www.Manualslib.com manuals search engine 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 have been approved for use
on General Motors vehicles. All passenger
type (P Metric) tires must
conform to Federal safety requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life and best overall performance.
1
In most cases, you will not need to have your wheels aligned again. 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.
-
Wheel Replacement
Replace any wheel that is bent, cracked or badly 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.

rire 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.

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 Cadillac, be sure
to follow the manufacturer’s warnings and instructions. And always open
your doors or windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline

Naphtha
Carbon Tetrachloride
0 Acetone
0 Paint Thinner
Turpentine

They can all be hazardous
-- some more than others -- and they can all
damage your vehicle, too.
