Traction Control System
Your vehicle has a traction control system that limits

If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Speed Sensitive Steering (SSS)
This system varies the amount of steering effort in
relation to your vehicle speed. Steering is easier at a
lower speed for maneuvering and parking ease. As your
vehicle speed increases, the steering effort
At highway speeds, the amount of steering effort
increased to provide manual-like steering for maximum
control and stability.
If your vehicle seems harder to steer
than normal when parking or driving slow, something
may be wrong with the speed sensitive steering system.
You will still have power steering, however, steering will
be stiffer than normal at low speeds.
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why: Experienced driver
or beginner, each of
us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to change its path when
the front wheels. If there’s no traction, inertia will keep
the vehicle going in the same direction.
If you’ve ever
tried to steer a vehicle
on wet ice, you’ll understand this.
The traction you can get in a curve depends on the condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While you’re
in a curve, speed is the one factor you can control.
Suppose you’re steering through a sharp curve. Then you suddenly accelerate.
Both control systems -- steering and
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too much of those places.
You can lose control. Refer to
“Traction Control System” in the Index.
What should you do if
this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
limit signs near curves warn that you should
adjust your speed.
Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to go slower.

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 vehicle’s
three control systems. In the braking skid, your wheels
aren’t rolling. In the steering or cornering skid, too
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
acceleration skid is also best handled by easing your
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
go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs. Of

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

snow on the road to make a “mirrored surface”
slow down when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.

Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation. You’ll
have a lot less traction or “grip” and will need to be
very careful. What’s the worst time for this? “Wet ice.”
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all.
You can get wet ice when it’s about
(32°F; 0°C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Keep your traction control system on. It improves your
ability to accelerate when driving on a slippery road.
Even though your vehicle has a traction control system,
you’ll want to slow down and adjust your driving to the
road conditions. See “Traction Control System” in the
Index. Also, see “Third Gear Start”
in the Index.

Spinning your wheels can destroy parts of your
vehicle as well as the tires.
If you spin the wheels
too fast while shifting your transmission back

Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. You should
turn your traction control system
off. (See “Traction
Control System” in the Index.) Then shift back and forth
between REVERSE (R) and a forward gear, spinning
wheels as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transmission is in gear. If that doesn’t
get you out after a few tries, you may need

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
If your tires have an all-season tread
design, the TPC number will be followed by
(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. Mixing
tires could cause you to lose control while
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
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.
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
of driving. A tire and/or wheel could
fail suddenly, causing
a crash. Use only radial-ply
tires with the wheels on your vehicle.

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
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
1/2) 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, fiom highest to lowest, are A, B, and
C, and they represent the tire’s ability
to stop on wet
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.
