engine PONTIAC FIREBIRD 1997 Service Manual

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
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.
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.
Traction Control System
(Option: LTI 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.

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.
TCS
OFF
When the system is on,
this warning light will
come on to let you how
if
there’s a problem with your
traction control. system.
See “Traction Control
System Warning Light”
in the Index.
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. Also, when
the compact spare tire is on
the rear axle, the traction
control system will cycle and limit acceleration for about
the first 15 seconds of driving after each engine start.
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.)
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.)

To turn the system off, press
the button located at the
front
of the console.
The light on
the switch will go off, and the traction
control system warning light 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 button should come
on, and the traction control system warning light should
go off. If
your car is equipped with P245/5OZR16 tires, the
traction control system will automatically turn
off at
speeds above 108 mph
(174 km/h). (The traction control
system warning light will not come on.) When the
vehicle speed drops below
103 mph (166 kmh) the
system will automatically come on again.
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.
4- 10

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
I
.A
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.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can
if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot
of water is standing on
the road.
If you can see reflections from trees, telephone
poles
or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddies or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared
to have your view restricted
by road spray.
“Tires” in the Index.)
Have good tires with proper tread depth. (See
4-19

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave
the freeway, move to the proper
lane well in advance.
If you miss your exit, do not,
under any circumstances, stop
and back up. Drive on to
the next exit.
The exit ramp can
be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower
than you actually are,
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in,
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
Pontiac dealerships all across North America.
They’ll be
ready and willing to help if you need it.

Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum
of the tires on the
road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don’t
let it
happen to you!
If it does, your vehicle can leave the
road in
less than a second, and you could crash and
be injured.
What can you
do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
4-23

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can
make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These
parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know
is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a
steep or long kill.
Coasting downhill! in NEUTRAL (N) or with
the ignition
off is dangerous. Your brakes will
have to do all the work of slowing
down. They
could get
so hot that they wouldn’t work well.
You would then have poor braking or even
none
going down a hill. You c’ould crash. Always have
your engine running and your vehicle in gear
when you! go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.

or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let

could be something in your lane, like a stalled car
or an accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area
or winding roads. Be alert to these and take
appropriate action.
As you go over the top of a hill, be alert. There

If You're Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle
unless you know for sure that you are near help
and you can hike through the snow. Here are some
things to do to summon help and keep yourself and your
passengers
safe:
Turn on your hazard flashers. Tie
a red cloth
to your vehicle to alert police that
you've been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets, or extra clothing, make body
insulators from newspapers, burlap bags, rags,
floor
mats -- anything you can wrap around yourself or
tuck under your clothing to keep
warm.
You can run the engine to keep warm, but be careful.
