1997 PONTIAC PONTIAC Owners Manual

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If
your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down.
If your engine
stops, you will still have some power brake assist. But
you
will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you
begin to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. See “Anti-Lock
Brake System Warning
Light” in the Index.

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you.
You slam
on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at the
rear wheels. 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.
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help
avoid a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in the Index.
Trac System (Option: Not Available with
3800 Supercharged Engine)
Your vehicle may have Trac 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 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 Trac System is
limiting wheel spin. See
“Trac System Active Light”
in
the Index. You may feel
or hear the system working,
but this is normal.
The Trac System operates in all transaxle shift lever
positions. But the system can upshift
the tran.saxle 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.

I TRAC
When the system is on and
the parking brake is fully
released, this warning light
will
come on to let you
know if there’s
a problem
with the system. See “Trac
System Warning Light” in
the Index.
To turn the system on or off,
press the TRAC button on
the on the far
right end of
the Driver Information
Center
or the optional
Trip Computer.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Trac System on.
But you can turn the 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.) When
you turn the system
off, the Trac System warning
light will come on and stay on. If the Trac System is
limiting wheel spin when you press the button to turn
the system off, 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 button again. The Trac 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.
Variable Effort Steering (Option)
This steering system provides lighter steering effort
for parking and when driving at speeds below
20 mph
(32 km/h). 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 eva
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. Unless you have the Trac System
and the system is on, adding
the sudden acceleration can
demand too much
of those places. You can lose control.
Refer to “Trac 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.
ProCarManuals.com

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 betw,een
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 Pontiac 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.
An emergency like this requires close attention and a
quick decision.
If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can
turn
it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible
is a good reason to practice defensive driving at
all times
and wear safety belts properly.

Off-Road Recovery
You may find sometime that your right wheels have
dropped
off the edge of a road onto the shoulder while
you’re driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up to one-quarter turn
until the right front tire contacts the pavement edge.
Then
turn your steering wheel to go straight down
the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then goes
back into the right lane again.
A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds.
A miscalculation, an error in
judgment, or a brief surrender to frustration or anger can
suddenly put the passing driver face to face with the
worst of all traffic accidents
-- the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road, to the sides and to
crossroads for situations that might af€ect your passing
patterns.
If you have any doubt whatsoever about
making a successful pass, wait for a better time.
Watch for traEc signs, p’avement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates
it’s all right to pass
(providing
the road ahead is clear). Never cross a solid
line on your side of the lane or a double solid line,
even if
the road seems empty of approaching traffic.

Do not get too close to the vehicle you want to pass
while you’re awaiting
an opportunity. For one thing,
following too closely reduces your area of vision,
especially if you’re following a larger vehicle.
Also, you won’t have adequate space if the vehicle
ahead suddenly slows or stops. Keep back a
reasonable distance.
0 When it looks like a chance to pass is coming up,
start to accelerate but stay in the right l’ane and
don’t get too close. Time your move
so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have a
“running start’’ that more than makes up for
the
distance you would lose by dropping back. And if
something happens to cause
you to cancel your pass,
you need only slow down and
drop back again and
wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as you pull out to pass
the slow vehicle.
Remember to glance over your shoulder and check
the blind spot.
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.)
0 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 8slowly moving vehicle too rapidly.
, Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
0 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.
