Anti-Lock Brake System Warning Light
(If Equipped)
The anti-lock brake system
warning light should come
on for a few seconds when
you turn the ignition key
to ON.
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, the anti
-lock brake system needs
service and 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 ON.
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
The traction control system
warning light may come on
for the following reasons:

If you turn the system off by pressing the TRAC OFF
button located on the instrument panel, a chime will
sound and 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 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.

2-90
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

This message will appear when the traction control
system is limiting wheel spin.
The message will stay on a few seconds after the
traction system stops limiting wheel spin.Battery Life Indicator
When the vehicle is started
this message will be
displayed for three seconds.
If the message is displayed when the engine is running,

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 (If Equipped)
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 briefly 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.
If there's a problem with the anti
-lock brake system,
the anti
-lock brake system warning light will stay on.
See ªAnti
-Lock Brake System Warning Lightº in
the Index.

Passing
The driver of a vehicle about to pass another on a
two
-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then goes
back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two
-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds. A miscalculation, an error
in judgment, or a brief surrender to frustration or anger
can suddenly put the passing driver face to face with the
worst of all traffic accidents
-- the head-on collision.
So here are some tips for passing:

ªDrive ahead.º Look down the road, to the sides and to
crossroads for situations that might affect your passing
patterns. If you have any doubt whatsoever about
making a successful pass, wait for a better time.

Watch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it's all right to pass
(providing the road ahead is clear). Never cross a solid
line on your side of the lane or a double solid line,
even if the road seems empty of approaching traffic.
Do not get too close to the vehicle you want to pass
while you're awaiting an opportunity. For one thing,
following too closely reduces your area of vision,
especially if you're following a larger vehicle.
Also, you won't have adequate space if the vehicle
ahead suddenly slows or stops. Keep back a
reasonable distance.

When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
don't get too close. Time your move so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have
a ªrunning startº that more than makes up for the
distance you would lose by dropping back. And if
something happens to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.

If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn't trying to
pass you as you pull out to pass the slow vehicle.
Remember to glance over your shoulder and check
the blind spot.
