{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you've pulled off the road and stopped
carefully, have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
If your vehicle is equipped
with the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That's
normal.If the light stays on, turn the ignition to OFF. Or, if the
light comes 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 regular brake system warning
light isn't on, you still have brakes, but you don't have
anti-lock brakes. If the regular brake system warning
light is also on, you don't have anti-lock brakes
and there's a problem with your regular brakes. See
Brake System Warning Light on page 3-26.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to RUN. This
is normal. If the light doesn't come on then, have it ®xed
so it will be ready to warn you if there is a problem.
3-27

Enhanced Traction System
Warning Light
If your vehicle is equipped with the Enhanced Traction
System (ETS), this warning light should come on
brie¯y as you start the engine. If the warning light
doesn't come on, then have it ®xed so it will be ready to
warn you if there's a problem.
If the warning light stays on, or comes on when you're
driving, there may be a problem with your Enhanced
Traction 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 Enhanced Traction System warning light may come
on for the following reasons:
·If you turn the system off by moving the shift lever
to FIRST (1) or SECOND (2), the warning light will
come on and stay on. To turn the system back
on, move the shift lever back to a position other than
FIRST (1) or SECOND (2). The warning light
should go off. See
Enhanced Traction System (ETS)
on page 4-8for more information.
·The warning light will come on when you set your
parking brake with the engine running, and it will stay
on if your parking brake doesn't release fully. If the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2) and the warning light
stays on after your parking brake is fully released, it
means there's a problem with the system.
·If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
·If the vehicle is driven on an extremely rough road,
the warning light may come on momentarily but will
go off again when the vehicle leaves the rough
surface.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2), your vehicle needs service. United States

Enhanced Traction System
Active Light
When your Enhanced Traction System is limiting wheel
spin, this light will come on. Slippery road conditions
may exist if the Enhanced Traction System active light
comes on, so adjust your driving accordingly.
This light may also come on when the anti-lock brake
system is active.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
on brie¯y when you turn the ignition key to RUN. If
the light doesn't come on then, have it ®xed so it will be
there to tell you when the system is active.
Engine Coolant Temperature Gage
Your vehicle is equipped with one of these gages. With
the ignition in RUN, this gage shows the engine
coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot! It means that your engine coolant has
overheated. The CHECK GAGES light should come on
if this condition exists. See
Check Gages Warning
Light on page 3-34for more information. If you have
been operating your vehicle under normal conditions,
you should pull off the road, stop your vehicle and turn
off the engine as soon as possible.

Your Driving, the Road, and
Your Vehicle
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start with a very important safety device in your
vehicle: Buckle up. See
Safety Belts: They Are for
Everyone on page 1-9.
Defensive driving really means ªbe ready for anything.º
On city streets, rural roads or freeways, it means
ªalways expect the unexpected.º
Assume that pedestrians or other drivers are going to
be careless and make mistakes. Anticipate what
they might do. Be ready for their mistakes.
Rear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough following
distance. It's the best defensive driving maneuver, in
both city and rural driving. You never know when
the vehicle in front of you is going to brake or turn
suddenly.Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the driving
task Ð such as concentrating on a cellular telephone call,
reading, or reaching for something on the ¯oor Ð makes
proper defensive driving more difficult and can even
cause a collision, with resulting injury. Ask a passenger to
help do things like this, or pull off the road in a safe place
to do them yourself. These simple defensive driving
techniques could save your life.Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy. It's the number one contributor to
the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to drive a
vehicle:
·Judgment
·Muscular Coordination
·Vision
·Attentiveness.
4-2

{CAUTION:
Drinking and then driving is very dangerous.
Your re¯exes, perceptions, attentiveness and
judgment can be affected by even a small
amount of alcohol. You can have a
serious Ð or even fatal Ð collision if you drive
after drinking. Please don't drink and drive or
ride with a driver who has been drinking. Ride
home in a cab; or if you're with a group,
designate a driver who will not drink.
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. Also see
Enhanced Traction
System (ETS) on page 4-8.
4-5

Braking
Braking action involvesperception timeandreaction time.
First, you have to decide to push on the brake pedal.
That'sperception time.Then you have to bring up your
foot and do it. That'sreaction time.
Averagereaction timeis 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 Ð heavy acceleration followed by heavy
braking Ð 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 pacewith 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 Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock
brakes, this warning light
on the instrument panel will
come on brie¯y when
you start your vehicle.
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.
4-6

Let's say the road is wet and you're driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. 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 wheel.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. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
4-7

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
®rmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
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 ®rst reaction Ð to hit the brake pedal hard and
hold it down Ð 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 ªsqueezeº braking
technique. This will give you maximum braking while
maintaining steering control. You can 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
dohave
anti-lock, it's different. See ªAnti-Lock Brake Systemº
in this section.
In many emergencies, steering can help you more than
even the very best braking.
Enhanced Traction System (ETS)
If your vehicle has the optional four-speed automatic
transaxle and anti-lock brakes, it also has an Enhanced
Traction System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions. The system
operates only when the transaxle shift lever is in the
REVERSE (R), THIRD (3) or AUTOMATIC
OVERDRIVE (D) position and the system senses that
one or both of the front wheels are spinning or beginning
to lose traction. When this happens, the system
reduces engine power and may also upshift the
transaxle to limit wheel spin.
4-8

This light will come on when your Enhanced Traction
System is limiting wheel spin. SeeEnhanced Traction
System Active Light on page 3-29.
You may feel or hear the system working, but this is
normal.
When the transaxle shift lever is in any position other
than FIRST (1) or SECOND (2) and the parking brake is
fully released, this warning light will come on to let
you know if there's a problem with the system.See
Enhanced Traction System Warning Light on
page 3-28. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System can operate when the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2). To limit wheel spin,
especially in slippery road conditions, you should
use REVERSE (R), THIRD (3) or AUTOMATIC
OVERDRIVE (D). See
Automatic Transaxle Operation
on page 2-22. If your vehicle ever gets stuck in
sand, mud or snow and rocking the vehicle is required,
see
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-29.
When you move the shift lever to FIRST (1) or
SECOND (2), the system will turn off. The Enhanced
Traction System warning light will come on and stay on.
If the Enhanced Traction System is limiting wheel
spin when you move the shift lever to another position,
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 moving
the shift lever to any position other than FIRST (1) or
SECOND (2). The Enhanced Traction System warning
light should go off. United States

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 apply the brakes. Both control
systems Ð steering and braking Ð 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 Ð steering and acceleration Ð can
overwhelm those places where the tires meet the road
and make you lose control. SeeEnhanced Traction
System (ETS) on page 4-8.
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 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.
