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.

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.
ABS
ACTIVE
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in the Index.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if you don’t have anti-lock, your
first reaction
-- to hit the brake pedal hard and hold it
down
-- may be the wrong thing to do. Your wheels can
stop rolling. Once they do, the vehicle can’t respond to
your steering. Momentum will carry it in whatever direction it was headed when the wheels stopped rolling.
That could be
off the road, into the very thing you were
trying to avoid, or into traffic.
If you don’t have anti-lock, use a “squeeze” braking
technique. This
will give you maximum braking while
maintaining steering control.
You do this by pushing on
the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease
off the brake pedal. This
will help
you retain steering control. (If you do have
anti-lock, it’s different: see “Anti-Lock Brakes” in
the Index
.)
In many emergencies, steering can help you more than
even
the very best braking.

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 apply the brakes. Both control
systems
-- steering and braking -- have to do their
work where the tires meet the road. Unless you have
four-wheel anti-lock brakes, adding the hard braking can
demand too much of those places. You can lose control.
The same thing can happen if you’re steering through a
sharp curve and you suddenly accelerate. Those two
control systems
-- steering and acceleration -- can
overwhelm those places where the tires meet the road and make you lose control.
What should you do
if this ever happens? Ease up on the
brake or 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.
If 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.

Downloaded from www.Manualslib.com manuals search engine 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 vehicle can perform very well in emergencies like
these. First apply your brakes
-- but, unless you have
anti-lock, not enough to lock your wheels. (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.
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.

Downloaded from www.Manualslib.com manuals search engine 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 vehicle’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 and
an acceleration skid are 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 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.
If you have the anti-lock braking system, remember: It
helps avoid only the braking
skid. If you do not have
anti-lock, then in a braking skid (where the wheels are
no longer rolling), release enough pressure on the brakes to get
the wheels rolling again. This restores steering
control. Push the brake pedal down steadily when you
have
to stop suddenly. As long as the wheels are rolling,
you will have steering control.

This multipurpose passenger vehicle is defined as a utility
vehicle
in Consumer Information Regulations issued by
the National Highway Traffic Safety Administration (NHTSA) of the United States Department of
Transportation. Utility vehicles have higher ground
clearance and a narrower track to make them capable of
performing in a wide variety of off-road applications.
Specific design characteristics
give them a higher center of
gravity than ordinary cars.
An advantage of the higher
ground clearance is a better view of the road allowing you
to anticipate problems. They are not designed for
cornering at the same speeds as conventional two-wheel-drive vehicles any more than low-slung sports
cars are designed to perform satisfactorily under off-road
conditions.
If at all possible, avoid sharp turns or abrupt
maneuvers. As with other vehicles of
this type, failure to
operate
this vehicle correctly may result in loss of control
or vehicle rollover.
Off-Road Driving with Your
Chevrolet Four-Wheel-Drive Vehicle
This off-road guide is for vehicles that have
four-wheel drive.
Also, see “Anti-Lock Brakes” in the Index.
If your vehicle doesn’t have four-wheel drive, you shouldn’t drive off-road unless you’re on
a level,
solid surface.
Off-road driving can be great fun. But it does
have some definite hazards. The greatest of these is the
terrain itself.
“Off-roading” means you’ve left the great North
American road system behind. Traffic lanes aren’t
marked. Curves aren’t banked. There are
no road signs.
Surfaces can be slippery, rough, uphill or downhill. In
short, you’ve
gone right back to nature.
Off-road driving involves some
new skills. And that’s
why it’s
very important that you read this guide. You’ll
find many driving tips and suggestions. These will help make your off-road driving safer and more enjoyable.

I
Shifting the transfer case to NEUTRAL (N) can
cause your vehicle to roll even if the transmission
is in
PARK (P) (or, if you have the manual
transmission, even
if you’re in gear). This is
because the NEUTRAL
(N) position on the
transfer case overrides the transmission. You or
someone else could be injured. If you are going to
leave your vehicle, set the parking brake and
shift the transmission to PARK
(P) (or, put your
manual transmission in FIRST
(1)). But do not
shift the transfer case to the NEUTRAL
(N)
position. Leave the transfer case in the 2H, 4H or
4L position.

Logs? Boulders?
What’s at the bottom of the hill?
Is there a hidden
creek bank
or even a river bottom with large rocks?
If you decide you can
go down a hill safely, then try to
keep your vehicle headed straight down, and use a low gear. This way, engine drag can help your brakes and
they won’t have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
Heavy braking when going down
a hill can cause
your brakes to overheat and fade. This could
cause loss
of control and a serious accident.
Apply the brakes lightly when descending
a
hill and use a low gear to keep vehicle speed
under control.

Light rain causes no special off-road driving problems. But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before you drive through
it.
If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t try it
-- you probably won’t get
through. Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly.
At fast speeds, water splashes on your ignition system
and your vehicle can stall. Stalling can also occur if you
get your tailpipe under water. And, as long as your
tailpipe is under water, you’ll never be able
to start your
engine. When you
go through water, remember that
when your brakes get wet, it may take you longer
to stop.
A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash
away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.

CAC 'ION:
-
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.
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.
