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. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
With this system, the
security light will flash as
you open the door, with the
ignition off, to let you
know that you are
activating the system.
This message 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 security light
should come on and flash. If using the remote
keyless entry transmitter, the door does not need
to be open.
If the delayed locking feature is active, the alarm
will not be activated until all doors are closed
and the security light goes off.
3. Close all doors. The security light will stop flashing
and stay solid. The light should go off after
approximately 30 seconds. The alarm is not armed
until the security light goes off.
If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle’s headlamps will flash and the horn will sound for
about two minutes, then will turn off to save the
battery power.
