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 is equipped with a content theft-deterrent
alarm system.
With this system, the
security light in the
instrument panel cluster
will flash as you open
the door if your ignition
is off.
This light reminds you to activate the theft-deterrent
system.
To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE)
transmitter. The security light will illuminate to
inform the driver the system is arming. If a door is
open when the doors are locked, the security
light will flash.
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 the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. See Delayed Locking on
page 2-11.
If a locked door is opened without the RKE transmitter,
the alarm will go off. The headlamps and parking
lamps will flash and the horn will sound for 30 seconds,
then will turn off to save the battery power.
