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.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the transmitter. The security light
should come on and stay on.
3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.
If a locked door or trunk is opened without using the key
in the driver’s door key cylinder or the transmitter, a
ten second pre-alarm will occur. The horn will chirp and
the lights will flash. If the ignition is turned to START
or the door is not unlocked by pressing the unlock button
on the transmitter during the ten second pre-alarm,
the alarm will go off. Your vehicle’s headlamps will flash
and the horn will sound for about 30 seconds, then will
turn off to save the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle’s key or the manual door
lock. It activates only if the power door lock switch
is used while the door is open or with the transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm has been
set off.
To avoid setting off the alarm by accident:
• Lock the vehicle with the door key after the doors
are closed.
• Always unlock a door with the transmitter. Unlocking
a door any other way will set off the alarm.
If you set off the alarm by accident, turn off the alarm by
pressing the unlock button on the transmitter. The alarm
will not stop if you try to unlock a door any other way.
