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.

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.
