Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Use a flat thin object to pry open the transmitter.
2. Once the transmitter is separated, use a pencil or
similar object to remove the old battery. Do not use
a metal object.

3. Insert the new battery as the instructions under the
cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.

Trunk Lid
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªComfort Controlsº
in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Remote Trunk Release Button
The remote trunk release
button is located on the
lower portion of the
driver's door.

Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transmission. And remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your key?

If possible, park in a busy, well
-lit area.

Put your valuables in a storage area, like your trunk
or glove box.

Be sure to close and lock the storage area.

Close all windows.

Lock the glove box.

2-20
Theft-Deterrent System
The security light is located
on the instrument panel
cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft
-deterrent
system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the remote keyless entry
transmitter or the power door lock switch. The
security light should come on and stay on.
3. Close all the doors. The security light should go off
within approximately 30 seconds.
If a door or a trunk is opened without a key or a remote
keyless entry transmitter, the horn will sound and the
lamps will flash for up to 30 seconds.The theft
-deterrent system won't arm if you lock the
doors with a key or use the manual door lock. It
activates only if you use the remote keyless entry
transmitter.
To avoid activating the alarm by accident do the
following:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the remote
keyless entry transmitter. Pressing the unlock button
on the remote keyless entry transmitter disables the
theft
-deterrent system. Unlocking a door any other
way will activate the alarm when a door or the trunk
is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter, or by starting the vehicle with a valid key.

2-21
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 switch or the
remote keyless entry transmitter and close the door.
Wait approximately 30 seconds until the security
light goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
exterior lamps will flash.
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 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.
Immobilizer
Your vehicle is equipped
with a passive
theft
-deterrent system.
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.

2-22
This device complies with RSS-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
authorized service facility could void authorization to
use this equipment.
The system works when you turn the key to ON (II).
The key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Your vehicle has a special key that works with the
theft
-deterrent system. There is a transponder in the key
head. If the key is ever damaged, you may not be able to
start your vehicle.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 who can service the theft
-deterrent
system to have a new key made.
It is possible for the theft
-deterrent system 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.
