Theft-Deterrent Systems
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.
Content Theft-Deterrent
Your vehicle may have the optional content
theft-deterrent alarm system.
With this system, a light on the radio will ¯ash.
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
¯ash 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 anincorrect key. The horn will sound and the headlamps
and back-up lamps will ¯ash 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 ¯ashes 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
¯ashing 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 ¯ash slowly to let you
know the system is armed.

and off.
One photocell on the front of the mirror senses when it
