Vehicle Damage Warnings
Also, in this book you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will 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 has 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 speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c name of a
component, gage or indicator, reference the following
topics:
·Seats and Restraint Systems in Section 1
·Features and Controls in Section 2
·Instrument Panel Overview in Section 3
·Climate Controls in Section 3
·Warning Lights, Gages and Indicators in Section 3
·Audio System(s) in Section 3
·Engine Compartment Overview in Section 5

door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry

get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry system and close the door. Wait 30
seconds until the SECURITY lamp goes off.

the hazard lights will ¯ash.
You can turn off the alarm by unlocking the driver's door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see

page 5-94. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

Section 3 Instrument Panel
3-1

Exterior Lamps
The exterior lamp control
is located to the left of the
steering wheel on the
instrument panel.
O(Exterior Lamp Control):Turn the control with
this symbol on it to operate the exterior lamps.
The exterior lamp control has three positions:
9(Off):Turn the control to this position to turn off all
lamps except the Daytime Running Lamps (DRL).
;(Parking Lamp):Turn the control to this position
to turn on the parking lamps together with the following:
·Sidemarker Lamps
·Taillamps
·License Plate Lamps
·Instrument Panel Lights
The parking brake indicator light will come on and stay
on while the parking lamps are on with the engine
off and the ignition in ACCESSORY or ON.
5(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
Wiper-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds. To operate, the Twilight
Sentinel
žfeature must be turned on.
When the exterior lamp control is in the off position or
parking lamp position and the wiper control is on delay,
LO or HI, the HEADLAMPS SUGGESTED message
will appear on the Driver Information Center (DIC).
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. The wiper-activated
headlamps will also turn off if the Twilight Sentinel
žor
the windshield wipers are turned off.
3-15

Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off approximately
10 minutes after the ignition is turned to OFF. This
protects against draining the battery in case you have
accidentally left the headlamps or parking lamps on. The
battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on. To delay the lamps from turning off,
see ªTwilight Sentinel
žº listed previously in this section.
Interior Lamps
Instrument Panel Brightness
This feature controls the brightness of the instrument
panel lights.
The knob for this feature is
located to the right of the
Twilight Sentinel
žlever.
Press the knob to release it to the outward position.
Turn the knob clockwise to brighten the lights or
counterclockwise to dim them. Press the knob to return
it to the original storage position.
3-19

The controls for this feature are located to the left of
and below the steering wheel. They are used to adjust
the brightness and location of the image. Adjust the
IMAGE control so the image is as low as possible while
remaining visible.
Slide the dimmer control until the image is no brighter
than necessary to clearly and comfortably see the image.
When the system comes on, you'll see the Night Vision
System symbol in the image. After about one minute, you
should see the view of the road ahead. If you don't see
the image after about two minutes (on cold days it may
take longer for the image to display), there may be
something wrong with the system. See your dealer for
service.
{CAUTION:
If the Night Vision System image is too bright,
or too high in your ®eld of view, it may take
you more time to see things you need to see
when it's dark outside. Be sure to keep the
image dim and placed low in your ®eld of view.
Remember that the Night Vision System, can only help
you see objects that are warmer or colder than the
surroundings. It can't sense things like brake lights, turn
signals or emergency ¯ashers, traffic lights or signs.
3-23

Ultrasonic Rear Parking Assist
(URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). This system can help you
to determine how close an object is to your rear bumper
within a given area, making parking easier.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system doesn't detect objects
that are more than 5 feet (1.5 meters) behind the
vehicle.
CAUTION: (Continued)
CAUTION: (Continued)
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using Rear Park Assist,
always check carefully behind your vehicle
before you back up and then watch closely
as you do.
The URPA display is
located inside the vehicle,
above the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.
