2-17 Testing the Alarm
1. From inside the vehicle, roll down the window.
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 vehicle, 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, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see ªFuses and Circuit Breakersº
in the Index.
If the alarm does not sound, or the exterior lamps do not
flash, see your dealer.
PASS-Key III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system.
This 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.
Page 82 of 402

2-18
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
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 ªFuses and
Circuit Breakersº 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 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.

2-35 Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is finished, the lever will
return automatically.
An arrow on the instrument
panel cluster will flash in
the direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
If the arrows flash very fast as you signal a turn or a lane
change, a signal bulb may be burned out and other
drivers won't see your turn signal.
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 ªFuses and Circuit
Breakersº in the Index.Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 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.
Headlamps
The headlamp control is located on the left steering
column lever.

If you can't see the HUD image when the ignition is on,
check to see if:
The HUD unit is covered,
the HUD dimmer control is adjusted correctly,
the HUD image is adjusted to the proper height, or
a fuse in the fuse panel may be blown. See ªFuses
and Circuit Breakersº in the Index.
If the HUD image is not clear, it could be too bright.
Move the HUD dimmer control further downward.
You may need to clean the windshield and HUD lens.
Your windshield is part of the HUD system. If you ever
have to have a new windshield, be sure to get one
designed for HUD. If you don't, the HUD image may
look blurred and out of focus.Systems Monitor (If Equipped)
If you have the systems
monitor, it gives you
important safety and
maintenance facts about
your vehicle.
When you turn the ignition on, the systems monitor and
warning lights will briefly light up. If a problem is
detected, the warning lights will turn on and a chime
will sound.

6-61 Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker. An electrical overload will cause the lamps to
go on and off, or in some cases to remain off.
If this happens, have your headlamp system checked
right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to have it fixed.
Power Windows and Other Power Options
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 damage
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 you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. Just 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.
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.
Removing Fuses
You will find a fuse puller attached in both of the BEC.
Snap the wide end of the fuse puller on to the fuse, at
the side indentations holding the puller and pull the
fuse out.
