Cruise Control (Option)
Cruise control can be dangerous whert: y’ou
can’t drive safely at a steady speed.
So,
don’t use your cruise control on winding
roads or in heavy traffic.
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.
Cruise control can be dangerous on
With cruise control, you can maintain a speed
of about
25 mph (40 kdh) or more without keeping your foot on
the accelerator. This can really help on long trips. Cruise
control does not work at speeds below about
25 mph
(40 km/h).
When you apply your brakes, the cruise control
shuts
off.
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
“Traction Control System” in the Index.) When
road
conditions allow you to safely use it again, you may turn
the cruise control back on.

Anti-Lock Brake System Warning Light
ANTI -
LOCK
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 light flashes when you’re driving, you don’t have
anti-lock brakes and there could be
a problem with your
regular brakes. Pull
off the road and stop carefully. You
may notice that the pedal is harder
to push. Or, the pedal
may
go closer to the floor. It may take longer to stop.
Have the vehicle towed for service. (See “Towing
Your
Vehicle” in the Index.)
1 CAUI
Your regular brake system may not be working
properly if the anti-lock brake system warning
light is flashing. Driving with the anti-lock
brake system warning light flashing can lead
to an accident. After you’ve pulled off the road
and stopped carefully, have the vehicle towed
for service.

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 but not flashing and the regular brake system
warning light isn’t on,
you still have brakes, but you
don’t have anti-lock brakes.
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.
Anti-Lock Brake System Active Light
LOW TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
the anti-lock brake system
active light will come on.
Slippery road conditions may exist if this light comes
on,
so adjust your driving accordingly. The light will
stay
on for a few seconds after the system stops
adjusting brake pressure.
The anti-lock brake system active 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 system is active.

Traction Control System Warning Light
(3800 Supercharged Engine Only)
TRAC
OFF
The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the traction
control button located on the black panel directly
behind your automatic transaxle shift lever, 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 “Traction Control System”
in the Index for more information.)
If there’s a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will
turn off and the warning light will come
on until your brakes
cool down.
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.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do
it. That’s reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part.
So do alcohol, drugs and
frustration. But even in
3/4 of a second, a vehicle
moving at
60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot
of distance in an emergency, so
keeping enough space between your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it’s pavement
or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight
of the
vehicle and the amount
of brake force applied.

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 (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.
ANTI -
LOCK
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash. 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 bralung 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
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
“Anti-Lock Brake System
Active Light”
in the Index.
Traction Control System
(With
3800 Supercharged Engine)
Your vehicle has 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 front wheels are spinning or beginning to lose traction.
When this happens, the system works the front brakes and
reduces engine power to limit wheel spin.
LOW TRAC
This light will come on
when your traction control
system is limiting wheel
spin. See “Traction Control
System Active Light” in
the Index.
You may feel or hear the system working, but this
is normal.
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
reengage the cruise control. (See “Cruise Control’’
in the Index.)
