1998 PONTIAC GRAND PRIX light

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.

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.
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
Traction Control System (With 3800
Supercharged Engine)
Your vehicle has 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 front wheels are spinning or beginning to lose traction.
When
this happens, the system works the front brakes and
reduces engine power to limit wheel spin.
LOW
TRAC
This light will come on
when your traction control system is limiting wheel
spin. See “Traction Control
System Warning Light” in
the index.
You may
feel or hear the system working, but this is normal.
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
reengage the cruise control. (See “Cruise Control” in the Index.)

This light should come on briefly when you start

the engine. If it stays on or
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.)
To turn the system off,
press the TCS button on
the far right end of the
trip computer.
The traction control system warning light will come
on and stay on. If the system is limiting wheel spin
when you press the button, the warning light will come
on -- and the system will shut-off instantly. 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 traction control system warning
light should go
off.

Enhanced Traction System
(3100 or 3800 Engine)
Your vehicle may have 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 Warning
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.

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

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 (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 ever
tried
to steer a vehicle on wet ice, you’ll understand this.

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 that your right wheels have dropped off the
edge
of a road onto the shoulder while you’re driving.
LEFT APPROX. WARTER TURN
edge of pamd wrfsco
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.

Here are some tips on night driving.
Drive defensively.
0 Don’t drink and drive.
0 Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.
0 Since you can’t see as well, you may need to
slow down and keep more space between you and
other vehicles.
0 Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.
0 In remote areas, watch for animals.
If you’re tired, pull off the road in a safe place
and rest.
Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50-year-old
driver may require at least twice as much light to see the same thing at night as a 20-year-old.
What you do
in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But
if you’re
driving, don’t wear sunglasses at night. They may cut down
on glare
from headlamps, but they also make a lot
of things invisible.
You can be temporarily blinded by approaching
headlamps.
It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When
you
are faced with severe glare (as from a driver who
doesn’t lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse
by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils
of your eyes contract repeatedly.
Remember that
your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it’s easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim,
so should your eyes
be examined regularly. Some drivers suffer
from night
blindness
-- the inability to see in dim light -- and
aren’t even aware
of it.
4-18

Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But
if you can't, try to slow down before you hit them.
A CAUTION:
Wet brakes can cause accidents. They won't work
as well
in a quick stop and may cause pulling to
one side. You could lose control of the vehicle.
After driving through
a large puddle of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.
