Control of a Vehicle
You have three systems that make your vehicle go where
you want it to
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’s
perception 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
3/4 of a second, a vehicle
moving at
60 mph (100 h/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; and the condition
of your brakes.

Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time. Tn many emergencies, steerirzg’cm help you more
thin 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
parlcitlg ad at low vehicle speeds. Steering effurt 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.
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.
4-10,

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 Enhanced Traction System and the system
is
on, adding the sudden acceleration can demand too
much of those places. You can lose control.
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 spe,eds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
If you need to reduce your speed as you approach a
1 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 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 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.

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 redly 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.
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 steeiing
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 Enhanced Traction System, remember: It
helps avoid only the acceleration skid.
If you do not have the Enhanced Traction System, or if
the system is off, then an acceleration skid is also best
handled by easing your foot
off the accelerator pedal.
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.

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.
Driving at Night
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 alcohol or drugs, with night vision problems, or by fatigue.
avoid only the braking skid. Night driving
is more dangerous than day driving. One
reason
is that some drivers are likely to be impaired -- by

Driving in Rain and on Wet Roads Rain and wet roads can mean driving trouble. On a wet
road, you can't stop, accelerate or turn as well because
your tire-to-road traction isn't as good
as on dry roads.
And, if your tires don't have much tread left, you'll get
even less traction. It's always wise to go slower
and be
cautious
if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.
The heavier the rain, the harder it
is to see. Even if your
windshield wiper blades are in good shape,
a heavy rain
can make
it harder to see road signs and traffic signals,
pavement markings, the edge of the road and even
people walking.
It's wise to keep your windshield wiping equipment in
good shape and keep your windshield washer tank filled
with washer fluid, Replace your windshield wiper
inserts when they show signs
of. streaking or missing
areas on the windshield, or when strips of rubber start to
separate from the inserts.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle
is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn’t happen often. But
it can if your
tires haven’t much tread or if the pressure in one or
more
is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or
other vehicles, and raindrops “dimple” the
water’s surface, there could
be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:.
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage
your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
TUm on your low-beam headlamps -- not just your
parking
lamps -- to help make you more visible to ‘’
others.
Besides slowing down, allow some extra following
distance.
And be especially careful when you pass
another vehicle. Allow yourself
more clear room
ahead, and be prepared to have your view restricted
by road spray.
“Tires”

Have good tires with proper tread depth. (See

The exit speed is usually posted.
Reduce your speed according
to your speedometer, not
to your sense of motion. After
driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must
start when you’re not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Weax comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to
go. If it needs
service, have it done before
starting out. Of course,
you’ll find experienced and
able service experts in
Pontiac dealerships all across North America. They’ll be
ready and willing to help
if you. need it. Here are some things
you can check before a trip:
WindshieZd Washer Fluid: Is the reservoir
full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
Lamps: Are they all working? Are the lenses clean?
‘Tires: They are vitally important to a safe,
all levels?
trouble-free
trip. Is the tread good enough for
long-distance driving? Are the tires all inflated
to the
‘ recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid a major
storm system?
Maps: Do you have up-to-date maps?
