your doors or unlock your trunk from about 3 feet (1 m)
up to 30 feet (9 m) away using the remote keyless entry
transmitter supplied with your vehicle.
Your remote keyless entry transmitter operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.

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 transaxle. And remember to lock the doors.

2-18
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.

Move the valet lockout switch to ON.

Lock the glove box.

Leave only the valet key.

Take all other keys and the remote keyless entry
transmitter with you.
Theft-Deterrent System
The SECURITY light is
located on the instrument
panel cluster.
If the ignition is off and any door is open, the SECURITY
light will flash, reminding you to arm the system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the remote keyless entry transmitter.
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 about 30 seconds.

2-19
Remember, 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 a power door lock with the
door open or 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 system. 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 system, or by starting the car with a
valid key.
Changes or modifications made to this system by other
than an authorized service facility could void
authorization to use the theft system.
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 or the
remote keyless entry system and close the door.
Wait 30 seconds until the SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
hazard lights 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.
