Anti-Lock Brakes (ABS)
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, or when you 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, and you may even notice that your
brake pedal moves or pulses a little. This is normal.

If there’s a problem with the
anti-lock brake system, this
warning light will stay
on.
See “Anti-Lock Brake
System Warning Light”
in
the Index.
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. 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 kont
of you, you won’t have time to apply you 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
finnly and let anti-lock work for you. You may feel a slight
brake
pedal pulsation or notice some noise, but this is normal.

When your anti-lock system
is adjusting brake pressure
to help avoid a braking
skid,
this light will come on. See
“Low Traction Light” in
the Index.
naction Control System (Option: 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 engine spark) to limit wheel
spin.
4-8

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. Adding the sudden acceleration
can demand too much of those places. You can lose
control. Refer to “Traction Control” 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.
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.
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. (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.
4-11

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 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.
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 tryins 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 is best handled by easing your foot off
the accelerator pedal.
If
you have the traction control system, remember: It
helps avoid only the acceleration skid.

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.
' A CAUTION:
I
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.

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your
trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work hard on
mountain roads.
Know how to
go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
ra CAUTION:
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope.
A CAUTION: I
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking
or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it’s about
freezing
(32°F; 0” C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
If you have traction control, keep the system on. It will
improve your ability to accelerate when driving on a slippery road. Even though your vehicle has a traction
control system, you’ll want to slow down and adjust
your driving to the road conditions. See “Traction
Control System”
in the Index.
If you don’t have the traction control system, accelerate
gently. Try not to break the fragile traction. If you
accelerate too fast, the drive wheels
will spin and polish
the surface under the tires even more. Your
anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road. Even
though you have the anti-lock braking system, you’ll
want to begin stopping sooner than you would
on dry
pavement. See “Anti-Lock” in the Index.
0 Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On
an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps of trees, behind buildings
or under bridges.
Sometimes the surface of a curve or an overpass may
remain icy when the surrounding roads are clear. If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

Towing a Trailer
A CAUTION:
F-
If you don’t use the correct equipment and drive
properly, you can lose control when you
pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered
by your warranty.
Pull a trailer
only if you have followed all the
steps in this section.
Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity
is for your vehicle, you
should read the information in “Weight of the Trailer”
that appears later
in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That’s the reason for
this part. In it are many
time-tested, important trailering tips and
safety rules.
Many
of these are important for your safety and that of
your passengers. So please read this section carefully
before
you pull a trailer.
Load-pulling components such
as the engine,
transmission, rear axle, wheel assemblies
and tires are
forced to work harder against the drag
of the added
weight.
The engine is required to operate at relatively
higher speeds and under greater loads, generating extra
heat. What’s more,
the trailer adds considerably to wind
resistance, increasing the pulling requirements.
