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 be equipped with a content
theft-deterrent alarm system.
The security light
is located on the
instrument panel
cluster.
Here's how to operate the system:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should flash.
3. Close all doors. The security light should turn off
after approximately 30 seconds. The alarm is not
armed until the security light turns off.
If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will flash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power.
Remember, the theft-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock switch
with the door open, or with the remote keyless entry
transmitter. You should also remember that you can start
your vehicle with the correct ignition key if the alarm has
been set off.
