Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
Your vehicle may have a
red light located on top of
the instrument panel,
toward the center of the
vehicle and near the
windshield, that will ash
slowly when the system is
armed.
The theft-deterrent alarm system needs to be activated
through the Driver Information Center (DIC). See
“CONTENT THEFT” under “Customization Menu Items”
inDIC Vehicle Personalization on page 3-74. While
armed, the doors will not unlock with the power door lock
switch. The remote alarm will sound if someone
tampers with the trunk or enters the vehicle without
using the Remote Keyless Entry (RKE) transmitter or
key to unlock the doors. The horn will sound and
the headlamps will ash for up to two minutes. The
system will also cut off the fuel supply, preventing the
vehicle from being driven.
Arming with the Power Lock Switch
The vehicle’s content theft-deterrent alarm system
can be activated when the key is removed from
the ignition and the power door lock switch of either the
driver’s or front passenger’s door is used to lock the
vehicle. The door needs to be in the open position when
pressing the power door lock switch. The system will
not arm if the door is closed when the power door
lock switch is pressed. This system can be activated
through the Driver Information Center (DIC). See
“CONTENT THEFT” under “Customization Menu Items”
inDIC Vehicle Personalization on page 3-74.
When the doors are locked using the power door
lock switch of either front door, the red light, if your
vehicle has one, will start ashing at a fast rate,
indicating that the system is arming. After all the doors
are locked there will be a time delay and then the
red light, if your vehicle has one, will begin to ash at a
very slow rate, indicating the system is armed.
