Testing the Alarm
The alarm can be tested by following these steps:
1.
From inside the vehicle, roll down the driver’s
window and open the driver’s door.
2.
Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3.
Get out of the car, close the door and wait for the
SECURITY light to go out.
4.
Then reach in through the window, unlock the door
with the manual door lock and open the door.
This should set off the alarm.
If the alarm does not sound when it should, but the
vehicle’s lamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse, see
Fuses and Circuit Breakers” in the Index.
If the alarm does not sound or the vehicle’s lamps do not
flash, the vehicle should be serviced by an authorized
service center.

means you don’t have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS

Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.

210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an

PASS
-
Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-
Key III system senses that someone is
using the wrong key, it shuts down the vehicle’s starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-
and
-
error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse (see “Fuses and
Circuit Breakers” in the Index). If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer or a locksmith who can service the
PASS
-
Key III to have a new key made.
It is possible for the PASS
-
Key III decoder to learn
the transponder value of a new or replacement key.
Up to 10 additional keys may be programmed for the
vehicle. This procedure is for learning additional keys
only. If all the currently programmed keys are lost or do
not operate, you must see your dealer or a locksmith
who can service PASS
-
Key III to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS
-
Key III to get a new key blank that is a cut
exactly as a current black colored driver’s key that
operates the system. Do not used a gray
-
colored valet
key for this procedure.

If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you
signal a turn, check the fuse (see “Fuses and Circuit
Breakers” in the Index) and for burned
-
out bulbs.
Turn Signal On Chime
If your turn signal is left on for more than 0.8 miles
(1.3 km), a chime will sound at each flash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam
or high beam to low beam, pull the turn signal lever
toward you and release it.
When the high beams are
on, this light located on the
instrument panel will
also be on.
If your vehicle is equipped with the Head
-
Up Display
(HUD), an arrow will also appear in the display area to
indicate the high beams are on (See “Head
-
Up Display
(HUD)” in Index for more information).
Flash-To-Pass
This feature lets you use the high
-
beam headlamps to
signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
Pull the turn signal lever toward you briefly to
flash
-
to
-
pass.
If the headlamps are off or on low beam, the high
-
beam
headlamps will turn on. They’ll stay on as long as you
hold the lever toward you and the high
-
beam indicator
on the instrument panel cluster will come on. Release
the lever to turn the high
-
beam headlamps off.

If the ignition is on and you can’t see the HUD image,
check to see if:
D
Something is covering the HUD unit.
D
The HUD dimmer control is adjusted properly.
D
The HUD image is adjusted to the proper height.
D
A fuse is blown. See “Fuses and Circuit Breakers”
in the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred or out of focus.
Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver Information
Center (DIC). The DIC will display information about
how your vehicle is functioning, as well as warning
messages if a system problem is detected. This feature also
allows two different drivers to store and recall their own
personal choice settings. See “DIC Personal Choice
Programming” later in this section.
DIC Displays and Controls
There are two lines in the DIC display. The DIC displays
the driver number identified when entering the vehicle.
You can have your dealer program your name to appear on
this display line. See your dealer for more information.
When you turn the ignition on, the DIC will display your
DRIVER NUMBER. The system will then perform a status
check and display any messages if a problem is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.
If a problem is detected, a diagnostic message will
appear in the display. The following pages will show the
messages you may see on the DIC display.
The message center is continuously updated with the
vehicle’s performance status.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add
-
on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see “Servicing
Your Air Bag
-
Equipped Vehicle” in the Index.
Power Windows and Other
Power Accessories
Circuit breakers in the rear electrical center protect the
power windows and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires caused
by electrical problems.
Look at the silver
-
colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating. If a MaxiFuse
R
should blow, see your dealer
for service immediately.

If you ever have a problem on the road and don’t have a
spare fuse, you can “borrow” one that has the same
amperage. Pick some feature of your vehicle that you
can get along without
--
like the radio or cigarette
lighter
--
and use its fuse, if it is the correct amperage.
Replace it as soon as you can. You will find a fuse puller
clipped in both of the bussed electrical centers. Snap the
wide end of the fuse puller at the side indentations and
pull the fuse out.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine compartment
on the passenger’s side and the other under the rear seat on
the driver’s side. If a MaxiFuse should blow, have your
vehicle serviced by your dealer immediately.
Engine Compartment Bussed Electrical
Center (BEC)
The front Bussed Electrical
Center (BEC) is located in
the front of the engine
compartment on the
passenger’s side. Lift the
cover to gain access.
