CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.
Limited-Slip Rear Axle
If your vehicle has this feature, your limited-slip rear
axle can give you additional traction on snow, mud, ice,
sand or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction
and the other does, this feature will allow the wheel with
traction to move the vehicle.

CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control.
Don't use cruise control on slippery roads.
If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin,
the cruise control will automatically disengage. (See
ªTraction Control Systemº in the Index.) When road
conditions allow you to safely use it again, you may turn
the cruise control back on.Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.

2-81 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay
on for three seconds.
That's normal.
If the anti
-lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you're driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you're driving, your vehicle needs service. If the
light is on and the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti
-lock brakes. Adjust your driving accordingly.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning Light
(Option)
This warning light should
come on briefly as you start
the engine. If the warning
light doesn't come on then,
have it fixed so it will be
ready to warn you if there's
a problem.
If it stays on, or comes on when you're driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.
The traction control system warning light will come on
if you turn the system off by pressing the TCS button
located in front of the console, the warning light will
come on and stay on. To turn the system back on, press
the button again. The warning light should go off.
(See ªTraction Control Systemº in the Index for
more information.)
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

2-82 Low Traction Light
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
If you have the traction control system, this light will also
come on when the system is limiting wheel spin. You
may feel or hear the system working, but this is normal.
Slippery road conditions may exist if the low traction
light comes on, so adjust your driving accordingly. The
light will stay on for a few seconds after the traction
control system stops limiting wheel spin.
The low traction light also comes on briefly when you turn
the ignition key to RUN. If the light doesn't come on
then, have it fixed so it will be there to tell you when the
anti
-lock brake system or traction control system is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area, your engine
is approaching an
overheating condition.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

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
firmly 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
ªLow Traction Lightº in
the Index.
Traction Control System
(Option)
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 for V8 engines works the rear brakes and for
V8 and V6 engines reduces engine power by closing the
throttle and managing engine spark to limit wheel spin.
This light will come on
when your traction control
system is limiting wheel
spin. See ªLow Traction
Lightº in the Index. You
may feel or hear the system
working, 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.

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 ªCruise Controlº in
the Index.)
When the system is on, this
warning light will come on
to let you know if there's
a problem with your
traction control system. See
ªTraction Control System
Warning Lightº in the Index.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always
leave the system on. But you can turn the traction control
system off if you ever need to. (You should turn the
traction control system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See ªRocking Your Vehicleº in
the Index.)
To turn the system off, press
the TCS button located at
the front of the console.
The light on the button will go off, and the traction
control system warning light will come on and stay on.
If the traction control system is limiting wheel spin
when you press the button, the light on the button will
go off and the warning light will come on
-- but the
system won't turn off right away. It will wait until
there's no longer a current need to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The light on the button should come
on, and the traction control system warning light
should go off.

4-11 Braking in Emergencies
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 ªdriver lost controlº 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. Adding the sudden acceleration can demand too
much of those places. You can lose control. Refer to
ªTraction Controlº 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 ªdriveº 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.

4-15
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 ªoverdrivingº
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.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 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
ªmirrored surfaceº
-- and slow down when you have
any doubt.
Remember: Any anti
-lock brake system (ABS) helps
avoid only the braking skid.

What's the worst time for this? ªWet ice.º 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 (32F; 0C) 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 ªTraction Control
Systemº 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 ªAnti
-Lockº in the Index.

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.
