Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when your engine
is started and may stay
on for several seconds.
That's normal.
If the ABS warning light comes on and stays on, there
may be a problem with the antilock portion of the brake
system. If the red BRAKE light is not on, you still have
brakes, but you don't have antilock brakes. See ªBrake
System Warning Lightº earlier in this section.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 ªBrake System
Warning Lightº earlier in this section.
The anti
-lock brake system warning light will come on
briefly when you turn the ignition key to ON. This is
normal. If the light doesn't come on then, have it fixed
so it will be ready to warn you if there is a problem.
If the ABS light stays on or comes on while you are
driving, pull off the road as soon as possible and stop
carefully. Try resetting the system by turning the
ignition off then back on. If the ABS light still stays on
or comes back on again while you are driving, your
vehicle needs service. Have the anti
-lock brake system
inspected as soon as possible.

Traction Control System Warning
(TRAC OFF) Light
If the TRAC OFF
warning light comes on
and stays on, there may
be a problem with the
traction control system.
The TRAC OFF light will come on briefly when you
turn the ignition to ON. If it doesn't come on then,
have it fixed so it will be ready to warn you if there is
a problem.The light will also come on if you turn the traction
control system OFF using the Traction On/Off button.
The traction control TC button is located in the
glove box.
If the TRAC OFF light stays on or comes on while you
are driving, pull off the road as soon as possible and stop
carefully. Try resetting the system by turning the
ignition off then back on. If the light still stays on or
comes back on again while you are driving, your vehicle
needs service. Have the traction control system
inspected as soon as possible. See ªTraction Control
Systemº in the Index.

Engine Coolant Temperature
Warning Light
This light tells you that your
engine has overheated.
This light will come on when you first start the vehicle
as a check to let you know that the light is working. It
will go out after a few seconds. If the light does not
come on, the bulb may be burned out. See your dealer
for assistance in changing the bulb.
If the light does not go out or if the light comes on and
stays on while you are driving, your vehicle may have a
problem with the cooling system. You should stop the
vehicle and turn off the engine as soon as possible to
avoid damage to the engine. A warning chime will
sound when this light is on, also.
See ªEngine Overheatingº in the Index.
Malfunction Indicator Lamp
(Check Engine Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.

4-7
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 Brake System (ABS)
Your vehicle has anti-lock brakes. 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, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
