2-15 Testing the Alarm
1. From inside the vehicle, roll down the window,
then 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
RKE system and close the door. Wait 30 seconds
until the SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
hazard lights will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the
RKE 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 ªFuses and Circuit Breakersº
in the Index. 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.
Valet Lock
This switch is located inside the glove box on the left
side. Pressing this switch to ON will disable the use of
the trunk, fuel door and garage door opener.
Pressing this switch to
OFF will enable these
features for use.
Locking the glove box with your key will also help to
secure your vehicle. Note that the RKE transmitter can't
open the trunk or fuel door if the valet lock switch is in
the ON position.

2-17
If the engine 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 ten 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 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 blank key that is cut
exactly as a current black colored driver's key that
operates the system. Do not use the gray colored
valet key for this procedure.To program the new key:
1. Insert the current driver's key (black in color) in the
ignition and start the engine. If the engine will not
start, see your dealer for service.
2. After the engine has started, turn the key to OFF and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within ten seconds of removing the previous key.
4. The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.
5. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
If you are ever driving and the SECURITY light
comes on and stays on, you will be able to start your
engine if you turn it off. Your PASS-Key III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS
-Key III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.

Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow located on the
instrument panel cluster
will flash in the direction
of the turn or lane change.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
-out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and check for burned
-out
bulbs if the arrow fails to work when signaling a turn.
Headlamp High/Low Beam
When the low-beam headlamps are on, push the turn
signal lever away from you to change the headlamps to
high beam.
This light on the
instrument panel cluster
will be on, indicating
high
-beam usage.
Pull the turn signal lever toward you to return to
low
-beam headlamps.

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 ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have the
headlamp wiring checked right away.
Windshield Wiper Fuses
A circuit breaker protects the wiper motor. If the wiper
motor overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
A MiniFuse
powers the wiper motor. If the MiniFuse
blows, there is an electrical problem. Be sure to have
it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed
or goes away.
Page 338 of 359

6-62 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 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 ªborrowº 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.
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.Underhood Junction Block
The front Bussed Electrical Center (BEC) is located
in the front of the engine compartment between the
windshield washer fluid reservoir and the power steering
fluid reservoir (on the passenger's side). Lift the cover
to gain access.
