If the SECURITY light comes on for one minute and
then shuts off while the ignition is on, the security
system has detected a problem with itself. See your
dealer for service.
If a door or the trunk is opened without the key or remote
keyless entry transmitter, the alarm will go off. It will
also go off if the trunk lock is damaged. Your vehicle's
lamps will flash and the horn will sound for one minute,
and then will go off in order to save battery power.
Remember, the theft
-deterrent system won't activate if
you lock the doors with a key or manual door lock. It
activates only if you use a power door lock switch with
a door open, or the remote keyless entry transmitter. You
should also remember that you can start your vehicle
with the correct ignition key if the alarm has been set
off. You must still shut off the alarm by inserting the key
in the door lock, or by pressing the UNLOCK button on
the remote keyless entry transmitter.
Here's how to avoid setting off the alarm by accident:

If you don't want to activate the theft
-deterrent
system, lock the door by using the door key or the
manual door lock switch.

Always unlock a door with a key, or use the remote
keyless entry system transmitter. Unlocking a door
any other way will set off the alarm.If you set off the alarm by accident, unlock any door
with your key.
You can also turn off the alarm by pressing UNLOCK
on the remote keyless entry transmitter, if you have it.
The alarm won't stop if you try to unlock a door any
other way.
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 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
ªFuses and Circuit Breakersº 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.

PASS-Key
II
Your vehicle is equipped
with the PASS
-Key II
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key II is a passive
theft
-deterrent system.
It works when you insert
or remove the key from
the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS
-Key II system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. For about three minutes, the starter
won't work and fuel won't go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY light turns on,
the key may be dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key appears
to be clean and dry, wait about three minutes and 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 starter won't work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS
-Key II.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY light will flash. But you don't have to wait
three minutes before trying another ignition key.

2-35 Turn and Lane Change Indicator
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 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 just stay on and don't flash 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) and for burned
-out bulbs.
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.
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 on the
instrument panel will
also be on.

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 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 Accessories
Circuit breakers in the fuse panel 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.
Maxifuse
/Relay Center
To check the fuses in this underhood fuse center, turn
the two knobs one
-quarter turn counterclockwise and
loosen the metal wing nut on the passenger side of the
cover. Then remove the cover. The inside of the cover
has a chart that explains the features and controls
governed by each fuse and relay.

6-59 Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. 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 ªborrowº 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.
There are two fuse blocks in your vehicle: the driver's
side and passenger's side fuse blocks.Driver's Side Fuse Block
The driver's side fuse block is to the left of the steering
wheel, under the instrument panel.
Snap off the cover to reveal the fuses. You'll find a fuse
puller clipped to the inside of the cover. Place the wide
end of the fuse puller over the plastic end of the fuse.
Squeeze the ends over the fuse and pull it out.
Spare fuses are located in the slots labeled ªSpareº on
the following chart.
When finished, replace the cover by snapping it back up
into place.
