1998 PONTIAC GRAND PRIX ABS

Trunk Access Panel (If Equipped)
If your vehicle has rear seat armrests, you will also have
a
trunk access panel. To use the trunk access panel, pull
your rear armrest down, unlock the access panel and pull
it down.
Rear Armrest Storage (If Equipped)
If you have a trunk access panel, you will also have a
pull down armrest that contains
an open storage bin and
two cupholders.
Convenience Net (If Equipped)
Your vehicle may have a convenience net. You’ll see it
on the back wall
of the trunk.
Put small loads, like grocery bags, in the net. It can help
keep them from falling over during sharp
turns or quick
starts and stops.
The
net isn’t for larger, heavier loads. Store them in the
trunk as far forward as you can.
You can unhook the net
so that it will lie flat when
you’re not using it.
Ashtrays and Lighter
The center front ashtray is an the instrument panel. To
open it, pull at the bottom of the ashtray until it is fully
open.
To remove the ashtray cup, lift the tabs on the
sides and pull out.
Your vehicle has one rear ashtray. There is either one on
the front seat armrest back
or one on the back of the
center console (if
you have that option). To open the
ashtray, press the right side and turn it open.
2-57

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.
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
both 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.

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.
4-17

Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you have overdrive, you may want to drive in
THIRD (3), instead of DRIVE (D).
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start
to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P).
5. Release the regular brakes. PARK (P) yet.
