1997 PONTIAC GRAND AM traction control

Cruise Control (If Equipped)
With cruise control, you can maintain a speed of about
25 mph (40 h/h) or more without keeping your foot on
the accelerator. This
can really help on long trips. Cruise
control does not work at speeds below about
25 mph
(40 km/h). When you apply your brakes
or push the clutch pedal
(if you have a manual transaxle), the cruise control
shuts off.
A CAUTION:
Cruise control can be dangerous where you
can’t drive safely at a steady speed. So,
don’t use your cruise control on winding
roads or in heavy traffic.
slippery roads. On such roads,
fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.

As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close
to the vehicle in
front of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to
stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You may feel the system
working, or you may notice some noise, but this is normal.
Enhanced Traction System (If Equipped)
If your vehicle has the optional four-speed automatic
transaxle, it also has an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only
if it
senses that one or both
of the front wheels are spinning
or beginning to lose traction. When this happens, the
system reduces engine power and may also upshift the
transaxle to limit wheel spin.
LOW
TRAC
This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See “Enhanced
Traction System Active Light” in the Index.
You
may feel or hear the system
working, but this is normal.
The Enhanced Traction System operates in all transaxle shift lever positions. But the system can upshift the
transaxle only as high
as the shift lever position you’ve
chosen,
so you should use the lower gears only when
necessary. See “Automatic Transaxle” in the Index.

Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
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.
Variable Effort Steering (If Equipped)
This steering system provides lighter steering effort for
parking and at low vehicle speeds. Steering effort will
increase at higher speeds for improved road feel.
Steering Tips
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 you turn
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 acceleration -- 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 “Enhanced Traction 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.
Speed 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.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
4-11

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek an escape route or area of less danger.
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 Pontiac’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.
If you have the Enhanced Traction System, remember: It
helps avoid only the acceleration skid.
If you do not have the Enhanced Traction System, or if
the 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.
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.

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. 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.

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.) 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.
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, 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.
