the vehicle's ignition is turned to ON or

an alarm period of 110 seconds has elapsed.
(Trunk Release): Press the button on the remote
keyless transmitter with the vehicle symbol on it to

-Deterrent
Systemº in the Index.

2-11
Transmitter Verification (If Equipped)
This feature provides feedback to the holder of the
remote keyless entry transmitter that a command has
been received by the keyless entry receiver. The
headlamps and back
-up lamps will flash on every lock
and the first unlock command, and the horn will sound
once for every lock and twice for the first unlock
command. Silent operation and other options may be
selected for this feature (see ªVehicle Customization
Settingsº in the Index).
If your vehicle has the optional content theft
-deterrent
system, the first time the remote unlock is received,
three flashes and chirps will be seen to indicate an alarm
condition has occurred since last arming. See ªContent
Theft
-Deterrent Systemº in the Index.
Illumination on Remote Activation
This feature provides interior illumination when a
remote keyless entry unlock command is received and
executed, the trunk release button is pressed or when
the panic alarm is activated. The interior lamps will
illuminate until the ignition is turned to ON or untilan illumination period of 40 seconds has elapsed or the
doors are locked with the power door lock switch or the
remote keyless entry transmitter. If a door is opened
during the illumination period, the timed illumination
will be canceled, and the interior lamps will remain on
while the door is open.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
If you prefer, you can complete this procedure yourself.
See ªVehicle Customization Settingsº in the Index for
more information.

2-13
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
seconds or until one brief horn chirp is heard.
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.

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.

2-17
Disabling the Trunk Release Sensor
A. Sensor Lens
B. Disable SwitchBecause the sensor detects motion, there are times when
you may want to turn off the trunk sensor so that the
motion of your vehicle or items in the trunk won't cause
the trunk to open, such as the following:

when your vehicle is transported on a car ferry,

when your vehicle is towed, or

when you will be loading items through the opening
in the split folding rear seat (if equipped).
Next to the sensor lens, there is a disable switch you can
use to turn off the trunk release sensor. To turn off the
sensor, turn the ignition to ON and press the switch next
to the lens for two seconds. The horn will chirp once
when the sensor is turned off. When the sensor is off,
the light in the switch will flash. The TRUNK OPEN
message in the message center will flash for one minute
each time the ignition is turned on as a reminder that
the sensor is turned off. See ªTrunk Open Messageº in
the Index.
To turn the sensor on again, press the switch again
or open the trunk. When the trunk is opened, the
sensor is automatically turned back on. If the sensor is
turned back on with the disable switch, the horn will
chirp twice.

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.
