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.

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.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But skids are
always possible.
The three types of skids correspond to your Pontiac’s
three control systems. In the braking skid, your wheels
aren’t rolling. In the steering or cornering
skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering
skid is best handled by easing your foot off
the accelerator pedal.
If you have the Trac System, remember: It helps avoid
only the acceleration skid. If
you do not have the Trac System, 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 slud
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.

If a Tire Goes Flat
10. Then replace the pressure cap. At any time during
this procedure if coolant begins to flow out
of the
filler neck, reinstall the pressure cap. Be sure the
mows
on the pressure cap line up like this.
11. Check the coolant in the recovery tank. The level
in the coolant recovery tank should be at the HOT
mark when the engine is
hot or at the COLD mark
when the engine is cold. It’s unusual for
a tire to “blow out”
while you’re driving,
especially
if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If
a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
slud and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and
noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a
flat tire safely.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to
a level place. Turn on your hazard
warning flashers,
Changing a tire can cause an Ijury. The vehicle
can slip off the jack and roll over you or other
people.
You and they could be badly injured.
Find
a level place to change your. tire. To help
prevent the vehicle
from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest
away from the one being changed.

- -
Raising your vehicle with the jack i
positioned can damage the vehicle and even make
the vehicle fall. To help avoid personal injury and
vehicle damage, be sure
to fit the jack lift head into
the proper location before raising the vehicle.
3. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the spare tire to fit under the vehicle.
Remove all wheel nuts and take off the flat tire.
4. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and

Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle.

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied.
This does not mean something is wrong with
your brakes.
Properly torqued wheel
nuts are necessary to help
prevent brake pulsation, When tires are rotated, inspect
brake pads for wear, and evenly torque wheel nuts in
the proper sequence
to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in section
7 of this
manual under
Part C “Perodic Maintenance Inspections,”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height,
or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your
brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have to be of top quality and work well
together if the vehicle is to have really good braking.
Vehicles we design and test have top-quality
GM brake
parts in them,
as your Pontiac does when it is new.
When you replace parts of your braking system
-- for
example, when your brake linings wlear down and you
have to have new ones put in
-- be sure you get new
approved
GM replacement parts. If you don’t, your
brakes may no longer work properly. For example,
if
someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes
can change -- for the worse. The braking performance
you’ve come to expect can change in many other ways
if
someone puts in the wrong replacement brake parts.
Battery
Every new Pontiac has a Delco Freedom@ battery. You
never have
to add water to ‘one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has
the replacement number shown
on the original battery’s label.
