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
Also see ªWarning Lights and Gagesº in the Index.

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.

Interior Lamps
Instrument Panel Brightness Lever
This feature controls the brightness of the instrument
panel lights.
The lever for this feature
is located on the
overhead console.
Slide the lever toward the symbol to brighten the lights
or away from it to dim them.
If you slide the lever all the way toward the symbol past
the resistance point, the interior lamps will come on. To
turn them off, slide the lever back toward the minimum
brightness setting.
Illuminated Entry
The illuminated entry system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for about
25 seconds. The illuminated entry system uses the light
sensor, it must be dark outside in order for the lamps to
turn on. The lamps turn off approximately 25 seconds
after the last door is closed. They will dim to off if the
ignition key is placed in ON, or immediately deactivate
if the power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument panel
displays can be adjusted by sliding the instrument panel
brightness lever toward the symbol to brighten or away
from the symbol to dim the lighting.

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.
