Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage
your vehicle.
In the notice area, we tell you about something that can
damage your vehicle. Many times, this damage would
not be covered by your warranty, and it could be costly.
But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different
colors or in different words.
You'll also see warning labels on your vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle may be equipped with components and
labels that use symbols instead of text. Symbols,
used on your vehicle, are shown along with the text
describing the operation or information relating to a
specific component, control, message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator reference the following
topics in the Index:

ªEngine Compartment Overviewº

ªInstrument Panelº

ªComfort Controlsº

ªAudio Systemsº

To release the parking brake, pull the release lever
located to the left of the steering wheel on the
instrument panel.
If the ignition is on, the brake system warning light
on the instrument panel cluster should come on. If it
doesn't, you need to have your vehicle serviced. See
ªBrake System Warning Lightº in the Index for more
information.
NOTICE:
Do not drive your vehicle with the parking brake
on. Driving with the parking brake engaged can
cause your vehicle's rear brakes to overheat. You
may have to replace them, and you could also
damage other parts of your vehicle.
A warning chime will sound if the parking brake is set,
the ignition is on and the vehicle begins to move. To
stop the chime, fully release the parking brake.
If you are towing a trailer and parking on a hill, see
ªTowing a Trailerº in the Index for more information.

Turn Signal On Chime
If the turn signal is left on for approximately 1 mile
(1.61 km), a warning chime will sound and the
Turn Signal On message will appear on the Driver
Information Center (DIC) display. See ªTurn Signal
On Messageº later in this section for more information.
Headlamps
The exterior lamp control is located at the end of the
turn signal/multifunction lever.
: Turn the control with this symbol on it to operate
the exterior lamps.
The exterior lamp control has three positions:
: Turning the control to this position turns off all
lamps except the Daytime Running Lamps (DRL).
: Turning the control to this position turns on the
parking lamps together with the following:

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights
: Turning the control to this position turns on the
headlamps, together with the previously listed lamps
and lights.
AUTO (Automatic): Turning the control to this
position puts the headlamps in automatic mode. AUTO
mode will turn the exterior lamps on and off depending
upon how much light is available outside of the vehicle.
Wiper
-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds. For this feature to work, the
exterior lamp control must be in AUTO.
When the exterior lamp control is off or in the parking
lamp position and the windshield wiper control is in any
position except off, the Headlamps Suggested message
will appear on the DIC display. See ªHeadlamps
Suggested Messageº later in this section for more
information.
When the ignition is turned to OFF, the wiper
-activated
headlamps will immediately turn off. They will also turn
off if the windshield wiper control is turned off.

change the headlamps from low to high beam. Pull the
lever back and then release it to change from high to
low beam.

panel cluster will be on,
indicating high
-beam usage.
Lamps On Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp
position and the driver's door is opened with the
ignition off.
Flash-To-Pass Feature
This feature allows you to use the high-beam headlamps
to signal the driver in front of you that you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use. When you do, the following will occur:

If the headlamps are either off, in low
-beam or in
Daytime Running Lamps (DRL) mode, the

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages. See
ªDriver Information Center (DIC)º later in this section
for more information.

Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on briefly when you turn
the ignition key to ON. If it doesn't come on then,
have it fixed so it will be ready to warn you if there's
a problem.When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
If the light comes on while you are driving, 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. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
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.

2-89
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.

2-90
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.
