traction control PONTIAC FIREBIRD 1998 Owners Manual

When you apply your brakes or push the clutch pedal
(manual transmission), the cruise control shuts off.
Setting Cruise Control
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.
Cruise control can be dangerous on
If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin, the
cruise control will automatically disengage. (See
“Traction Control System”
in the Index.) When road
conditions allow
you to safely use it again, you may turn
the cruise control back on.
If you leave your cruise control switch on when
you’re not using cruise, you might hit
a button
and
go into cruise when you don’t want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.

Anti-Lock Brake System Warning Light
ABS
INOP
With the anti-lock brake system, this light will come
on when you start your
engine and
it will stay
on for three seconds.
That’s normal.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system.
If the light still stays on, or comes on again
while you’re driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn’t on, you still have brakes, but you don’t have
anti-lock brakes. Adjust your driving accordingly.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning Light
(Option)
This warning light should
come on briefly
as you start
the engine. If the warning
light doesn’t come on
then,
have it fixed so it will be
ready to warn you if there’s
a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not
limit wheel spin. Adjust your
driving accordingly.
The traction control system warning light will come on
if
you turn the system off by pressing the TCS button
located in front
of the console, the warning light will
come on and stay on. To turn the system back on,
press the button again. The warning light should go
off. (See “Traction Control System” in the Index for
more information.)
If
the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Low Traction Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on.
If you have the traction control system, this light will
also come on when the system is limiting wheel spin.
You may feel or hear the system working, but this is
normal. Slippery road conditions may exist if the low
traction light
comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the traction control system stops limiting
wheel spin.
The low traction light
also comes on briefly when you
turn the ignition key to
RUN. If the light doesn’t come
on then, have it fixed so it will be there to tell you when
the anti-lock
brake system or traction control system
is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into
the red area,
your engine
is too hot! It means that
your engine coolant
has overheated.
If you have been operating your vehicle under normal
driving conditions,
you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed
to make the most of available tire and
road conditions.
You can steer around the obstacle while braking hard.
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 kont
of you, you won’t have time to apply you 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
finnly and let anti-lock work for you. You may feel a slight
brake
pedal pulsation or notice some noise, but this is normal.
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking
skid,
this light will come on. See
“Low Traction Light” in
the Index.
naction Control System (Option: V8 Engine)
Your vehicle may have a traction control system 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 rear wheels are spinning or beginning to
lose traction. When
this happens, the system works the
rear brakes and reduces engine power (by closing the
throttle and managing engine spark) to limit wheel
spin.
4-8

LOW
TRAC
This light will come
on when your traction
control system is limiting wheel spin.
See “Low Traction Light” in the Index. You may
feel or hear the system working, but this is normal.
The traction control system may operate on
dry roads
under some conditions, and you may notice a reduction
in acceleration when this happens. This
is normal and
doesn’t mean there’s a problem with your vehicle.
Examples of these conditions include a hard acceleration
in a turn, or an abrupt upshift or downshift.
If your vehicle
is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow
you to safely use it again, you may
re-engage the cruise control. (See “Cruise Control”
in the Index.)
TCS
OFF
When the system is on, this
warning light will come
on
to let you know if there’s a
problem with your traction
control system.
See “Traction Control System Warning Light” in
the Index.
When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes
on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system
off if you ever need to.
(You should turn the system off if your vehicle ever
gets stuck in sand, mud, ice or snow. See “Rocking
Your Vehicle”
in the Index.)
4-9

L
To turn the system off, press
the
TCS switch located at
the front
of the console.
The light on
the switch will go off, and the traction
control system warning light in
the cluster will come on
and stay on.
If the traction control system is limiting
wheel spin when you press the switch, the light on the switch will
go off and the warning light will come on --
but the system won’t turn off right away. It will wait
until there’s no longer a current need to limit wheel spin.
You can turn the system back on at any time by pressing
the switch again. The light on the switch should come
on,
and the traction control system warning light
should
go off.
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.
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.
4- 10

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 “Traction Control” 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. Try to adjust
your speed so you can “drive” through
the curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective than
braking. For example, you come over a hill and find a
truck stopped
in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front of you. You can avoid these
problems by braking
-- if you can stop in time. But
sometimes you can’t; there isn’t room. That’s the time \
for evasive action
-- steering around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes. (See “Braking in
Emergencies” earlier in this section.) It is better to
remove as much speed as you can from a possible
collision. Then steer around the problem, to the left
or right depending on the space available.
4-11

Check your mirrors, glance over your shoulder, and start your
left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead
of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right
lane. (Remember that
your right outside mirror
is convex. The vehicle YOU
just passed may seem to be farther away from YOU
than it really is.)
Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn,
If you’re being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.
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 tryins 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 vehicle’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 traction control system, remember: It
helps avoid only the acceleration skid.
4-14

If you do not have traction control, 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.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems,
or by fatigue.
