Resynchronization
After you have changed the battery in your transmitter,
you will need to resynchronize the transmitter. To do
this, press the LOCK and UNLOCK buttons on the
transmitter together and hold for approximately seven

Trunk
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 with the setting
on VENT. 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.

the lock and turn it. You can also press the car symbol
on your remote keyless entry transmitter (if equipped).

control on the underside of

trunk lid toward the driver's side of the vehicle.

2-16 Trunk Release Sensor TrapAlert
System
(If Equipped)
Your vehicle may have a sensor located on the underside
of the filler panel inside the trunk.If your vehicle has this feature, the sensor is designed to
open the trunk automatically under certain conditions.
If the sensor detects motion and a difference in
temperature in the trunk, the sensor will sound the horn
if the ignition is in OFF. There will be three short chirps
and a pause repeated for up to two minutes. After one
minute, the trunk latch will release. If the ignition is not
in OFF, the trunk latch will not release automatically
and the horn will not sound.
To cancel the horn alarm and automatically release the
trunk lid before two minutes are up, turn the ignition
to ON.
Do not cover the sensor with items you put into the
trunk or with add
-on accessory equipment. If the
sensor's field of view is blocked, it will not detect
motion and will not function properly.
Be sure to secure items in your trunk so that they won't
move around and cause the trunk to open.

2-18
Servicing the Trunk Release Sensor
The sensor lens should be inspected periodically. If the
lens is dirty, wipe it gently with a clean, soft cotton cloth.
If there is an electrical problem with the sensor, the
SERVICE VEHICLE SOON message will appear in the
message center. There are other possible reasons for this
message to appear. Be sure to see your dealer as soon as
possible. See ªService Vehicle Soon Messageº in the
Index for more information.
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 ignition and transaxle will be locked. 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
ignition 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.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

2-19
Content Theft-Deterrent (Option)
Your vehicle may have the optional content
theft
-deterrent alarm system.
With this system, a light on the radio will flash.
This light reminds you to activate the theft
-deterrent
system. Here's how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or the
remote keyless entry transmitter. The light on the
radio should come on and stay on. If you are using
the remote keyless entry transmitter, the door does
not need to be open.
3. Close all doors. The light on the radio will slowly
flash once the system is armed.
Once armed, the alarm will go off if someone tries to
enter the vehicle (without using the remote keyless entry
transmitter or a key) or turns the ignition on with an
incorrect key. The horn will sound and the headlamps and
back
-up lamps will flash for approximately two minutes.When the alarm is armed, the trunk may be opened with
the remote keyless entry transmitter. If you use the key
to open the trunk, the alarm will sound. The power door
lock switches are also disabled. You must use your
remote keyless entry transmitter or your key to unlock
the doors when the system is armed.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
lock switch to lock the doors while any door or the trunk
is open and the key is removed from the ignition.
The light on the radio flashes quickly to let you know
when the system is ready to arm with the power door
lock switches. The light on the radio will stop flashing
and stay on when you press the bottom of the power
lock switch, to let you know the system is arming.
After all doors and the trunk are closed and locked, the
light on the radio will flash slowly to let you know the
system is armed.

2-20 Arming with the Remote Keyless
Entry Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key is
not in the ignition. The light on the radio will turn on to
let you know the system is arming. After all doors and
the trunk are closed and locked, the light on the radio
will begin flashing at a very slow rate to let you know
the system is armed.
Disarming with the Remote Keyless
Entry Transmitter
Your alarm system will disarm when you use your
remote keyless entry transmitter to unlock the doors.
The light on the radio will go off to let you know the
system is no longer armed.
The first time a remote UNLOCK command is
received, three flashes will be seen and three horn chirps
heard to indicate an alarm condition has occurred since
last arming.
Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the doors. The light on the radio will go off to
let you know the system is no longer armed.
