brake PONTIAC GRAND AM 1998 Owner's Manual

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may
go closer to the floor.
It may take longer to stop. If the light
is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
I A CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead to an accident.
If the light is still on after you’ve
pulled off the road and stopped carefully, bqve
the vehicle towed for service.
When the ignition is on, the brake system warning light
will
also come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully.
If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
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 light stays on, turn the ignition to OFF. Or, if the
light comes 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 regular brake system warning light isn’t
on, you still have brakes, but you don’t have anti-lock
brakes.
If the regular brake system warning light is also
on, you don’t have anti-lock brakes and there’s a
problem with
your regular brakes. See “Brake System
Warning Light” earlier in this section.
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.

Enhanced Traction System Warning Light
(If Equipped)
ETS
OFF
t With the Enhanced Traction System (ETS),
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 the warning light stays on, or comes on when you’re
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When
this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.

If you turn the system off by pressing the button an
the shift lever, 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
“Enhanced Traction System” in the Index for more
information.)
The warning light will
come on when you set your
parking brake with the engine running, and it will
stay on if your parking brake doesn’t release fully.
If
the system is turned on and the warning light stays
on after your parking brake is fully released, it
means there’s
a problem with the system.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
system
is turned on and the parking brake is fully
released, your vehicle needs service.

Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
Pontiac: Buckle up. (See “Safety Belts” in the Index.)
Defensive driving really means “be ready for anything.”
On city streets, rural roads
or freeways, it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going to be
careless
and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Rear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough
following distance. It’s the best defensive driving
maneuver, in both city and rural
driving. You never
know when the vehicle in front of you is going to brake
or
turn suddenly.
4-2

Control of a Vehicle
You have three systems that make your vehicle go where
you WaTlf it ro go. They are the brakes, the steering and
the accelerator.
All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more
of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First,
you have to decide to push on the brake pedal.
That’sperception time. Then you have to bring
up your
foot and do it. That’s reaction time.
Average reaction time is about
3/4 of a second. But
that’s only an average. It might be
less with one driver
and as long as
two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight
all play a part. So do alcohol, drugs and
frustration. But even in 314 of a second, a vehicle
moving at
60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it’s pavement or
gravel); the condition
of the road (wet, dry, icy); tire
tread; the condition
of your brakes; the weight of the
vehicle and the amount of brake force applied.
4-6

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 or pulses a little.
This is normal.
If there’s a problem with the
anti-lock brake system,
this
warning light will stay on.
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. 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.
4-8

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
firmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation
or notice some noise, but
this is normal.
Enhanced Traction System
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.
ETS
OFF
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 “Enhanced Traction System
Warning Light” in the
Index. When
this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
4-9

To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction 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.)
To turn the system on or off,
press the button on the shift
lever knob.
When
you turn the system off, the Enhanced Traction
System warning light will come on
and stay on. If the
Enhanced Traction 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 Enhanced Traction 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 (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.
4-10

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.
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.

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 lane 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
0

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 trying to steer and
constantly seek an escape route or area of less danger.
