Downloaded from www.Manualslib.com manuals search engine Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not “overdriving”\

those conditions. But skids are always possible.
The three types of skids correspond to your Cadillac’s
three control systems.
In the braking skid, your wheels
aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
Remember: Any traction control system helps avoid
only the acceleration skid.
If your traction control system is off, then an
acceleration
skid is also best handled by easing your
foot
off the accelerator pedal.
If your vehicle starts to slide, ease your foot
off the
accelerator pedal and quickly steer the way
you want the
vehicle to
go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
If you have the DeVille Concours, you may see the
STABILITY
SYS ENGAGED message on the Driver
Information Center. See “Stability Engaged Message’’ in
the Index.
Of course, traction
is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting
to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn
to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a “mirrored surface”
-- and slow
down when you have
any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.

Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 Pa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly
inflated simply by looking at them. Radial tires may
look properly inflated even when they’re underinflated.
Be 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 most important. See “Scheduled
Maintenance Services” in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct
rotation pattern shown here.
Don’t include the compact spare tire in your
tire rotation.

Downloaded from www.Manualslib.com manuals search engine 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.
I
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.

Downloaded from www.Manualslib.com manuals search engine ___ form Tire Quality Grading Treadwear
me 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. 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.
6-45
Warning: The traction grade assigned to this tire is based '
on braking (straightahead) traction tests and does not
include cornering (turning) traction.

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
or spinning the wheels
with chains on will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flames 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:
0 Gasoline
Benzene
0 Naphtha
0 Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
0 Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
Don’t use any
of these unless this manual says you can.
In many uses, these will damage your vehicle:
Alcohol
0 Laundry Soap
Bleach
0 Reducing Agents

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:

Always read the instructions on the cleaner label.
Clean up stains as soon as you can
-- 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.
