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
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 and 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. This is normal.
If there’s
a problem with the
anti-lock brake system,
this
warning light will stay on.

System Warning Light’‘

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 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.
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 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
and
let anti-lock work for you. You may feel the brakes
vibrate, or you may notice some noise, but this
is
normal. On vehicles with four-wheel drive, your
anti-lock brakes work at all times
-- whether you are in
two-wheel drive
or four-wheel drive.
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.

Road Rea ---:y
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.
You may find sometime that your right wheels have
dropped off the edge of a road
onto the shoulder while
you’re driving.
- - -r- --
OFF-ROAD RECOVERY RECOVER
0-
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator
and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up to one-quarter turn
until the right front tire contacts the pavement edge. Then
turn your steering wheel to go straight down the roadway.
ProCarManuals.com

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.
Remember:
Any anti-lock brake system (ABS) helps
avoid
only the braking skid.
Driving Guidelines
Off-Road Driving with Your
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.
Surfxes 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.

Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However,
it also raises environmental
concerns.
GM recognizes these concerns and urges
every off-roader to follow these basic rules for
protecting the environment:
a
e
e
a
0
Always use established trails, roads and areas that
have been specially set aside for public off-road
recreational driving; obey all posted regulations.
Avoid any driving practice that could damage the
environment
-- shrubs, flowers, trees, grasses -- or
disturb wildlife (this includes wheel-spinning,
breaking down trees
or unnecessary driving through
streams or over soft ground).
Always carry a litter bag
-- make sure all refuse is
removed from any campsite before leaving.
Take extreme
care with open fires (where permitted),
camp stoves and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch fire from the
heat
of the vehicle’s exhaust system.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to a remote area. Know
the terrain and plan your route.
You are much less likely to get bad surprises. Get
accurate maps
of trails and terrain. Try to learn of any
blocked or closed roads.
It’s also a good idea to travel
with at least one other
vehicle.
If something happens to one of them, the other
can help quickly.
Does your vehicle have a winch?
If so, be sure to read
the winch instructions.
In a remote area, a winch can be
handy
if you get stuck. But you’ll want to know how to
use
it properly.
Gett.ing Familiar with Off-Road Driving
It’s a good idea to practice in an area that’s safe and
close to home before you go into the wilderness.
Off-road driving does require some new and different
driving skills. Here’s what
we mean.
Tune
your senses to different kinds of signals. Your
eyes,
for example, need to constantly sweep the terrain
for unexpected obstacles.
Your ears need to listen for
unusual tire or engine
sounds. With your arms, hands,
feet and body, you’ll need to respond to vibrations and
vehicle bounce.

Approaching a Hill
When you approach a hill, you need to decide if it’s one
of those hills that’s just too steep to climb, descend or
cross. Steepness can be hard
to judge. On a very small
hill, for example, there may be a smooth, constant
incline with only
a small change in elevation where you
can easily see all the way to the top. On a large hill, the
incline may get steeper as you near the top, but you may
not see this because the crest of the hill is hidden by
bushes, grass or shrubs.
Here are some other things to consider
as you approach
a hill.
Is there a constant incline, or does the hill get sharply
steeper
in places?
Is there good traction on the hillside, or will the
surface cause tire slipping?
Is there a straight path up or down the hill so you
won’t have to make turning maneuvers?
Are there obstructions on the hill that can block your
path (boulders, trees, logs
or ruts)‘?
0 What’s beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and walk the
hill
if you don’t know. It’s the smart way to find out.
Is the hill simply too rough? Steep hills often have
ruts, gullies, troughs and exposed rocks because they
are more susceptible to
the effects of erosion.
Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.
Use a low gear and get a firm grip on the steering
wheel.
Get a smooth start up the hill and try to maintain
your speed. Don’t use more power than
you need,
because
you don’t want your wheels to start spinning
or sliding.
