Your Driving and the Road
Here’s how anti-lock works. Let’s say
the road is wet. You’re driving safely.
Suddenly an animal jumps out in front
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 the 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.
of you.
. . .I30
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.
Remember: Anti-lock doesn’t change the
time you need to get your foot
up to the
brake pedal. 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.
To Use Anti-Lock
Don’t pump the brakes. Just hold the
brake pedal down and let anti-lock work for
you. You may feel the system
working, or you may notice some noise,
but this is normal. When your anti-lock system is adjusting brake pressure to help
avoid a braking skid, the “LOW TRAC”
light will come on. See “Low Traction
Light” in the Index.
Traction Control System (Option: LT1
V8 Engine)
Your vehicle may have 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 rear wheels
are spinning or beginning to lose traction.
When this happens, the system works the
rear brakes and reduces engine power (by
closing the throttle and managing spark)
to limit wheel spin.
The “LOW TRAC” light will come on
when your traction control system is
limiting wheel spin. See “Low Traction Light” in the Index.
You may feel the
system working, or you may notice some
noise, but this is normal.
The traction control system may operate
on dry roads under some conditions, and
you may notice a reduction
in acceleration
when this happens. This is normal and
doesn’t mean there’s a problem with your vehicle. Examples of these conditions
include a hard acceleration in a turn, or
an abrupt upshift or downshift.

TCS
OFF
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 re-engage the cruise
control. (See “Cruise Control”
in the
Index.)
The “TCS
OFF” warning light will come
on when you turn the traction control system off. When the system is on, this
light will come on to let you know if
there’s a problem with your traction
control system. 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.

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.
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.
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.
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 traction control 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 speeds are based on good
weather and road conditions. Under less
favorable conditions you’ll want to go
slower.
[f you need to reduce your speed as you
approach a 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
rhere are times when steering can be
.nore 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
:mergencies like these. First apply your
)rakes. It is better to remove as much
;peed as you can from a possible
:ollision. 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
mce you have avoided the object.
The fact that such emergency situations
xe always possible is a good reason to
practice defensive driving at all times and
wear safety belts properly.

Your Driving and the Road
Passing
The driver of a vehicle about to pass
another on a two-lane highway waits for
just the right moment, accelerates, moves
around the vehicle ahead, then goes back
into the right lane again. A simple
maneuver?
Not necessarily! Passing another vehicle
on a two-lane highway is a potentially
dangerous move, since the passing
vehicle occupies the same lane as
oncoming traffic for several seconds.
A
miscalculation, an error in judgment, or a
brief surrender to frustration or anger can
suddenly put the passing driver face to
face with the worst of all traffic accidents
- the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road,
to the sides, and to crossroads for
situations that might affect your
passing patterns. If you have any
doubt whatsoever about making a
successful pass, wait for a better time.
Watch for traffic signs, pavement
markings, and lines. If you can see a
sign up ahead that might indicate a
turn or an intersection, delay your
pass.
A broken center line usually indicates
it’s all right to pass
(providing the road ahead is clear).
Never cross a solid line
on your side
of the lane or a double solid line, even
if the road seems empty of
approaching traffic.
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.
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. 0
0
0
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 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 lights 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.
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.
[f you have the traction control system,
remember:
It helps avoid only the
acceleration skid. If you do not have
traction control, 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
bot 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 recqgnize
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 braking system
(ABS) helps avoid only the braking skid.

Dyz’ving ut Night
Night driving is more dangerous than day
driving. Oqe reason is that some drivers
are likely to be impaired
- by alcohol or
drugs, with night vision problems, or by
fatigue.
Here are some tips on night driving.
Drive defensively.
Don’t drink and drive.
Adjust your inside rearview mirror to
reduce the glare from headlights
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.
Slow down, especially on higher
speed roads. Your headlights can
up only
so much road ahead. light
0 In
remote areas, watch for animals.
0 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 headlights, but they also
make a lot of things invisible.
You can be temporarily blinded by
approaching lights. It can take a second or
twQ, 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 headlights), slow
down
a little. Avoid staring directly into
the approaching lights.
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 headlights 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 headlights should be
checked regularly for proper aim,
so
should your eyes be examiqed regularly. Some drivers suffer from night blindness
- the inability to see in dim light - and
aren’t even aware of it.

Your Driving and the Road
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.
Some Other Rainy Weather Tips
Turn on your low-beam headlights -
not just your parking lights - 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.
Have good tires with proper tread
depth. (See “Tires” in the Index.)
City Driving
One of the biggest problems with city
streets is the amount of traffic on them.
You’ll want to watch out for what the
other drivers are doing and pay attention
to traffic signals.
Here are ways to increase your safety in
city driving:
Know the best way to get to where
you are going. Get a city map and plan
your trip into an unknown part of the
city just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross most large cities. You’ll save time and energy. (See the next
section, “Freeway Driving.”)
