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 have a content theft-deterrent
alarm system.
A red light located on
top of the instrument
panel, toward the center
of the vehicle and
near the windshield, 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 229. 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 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.
104

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 alarm system will not
activate 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 229.
When the doors are locked using the power door
lock switch of either front door, the red light on
top of the instrument panel 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 will begin to ash
at a very slow rate, indicating the system is armed.
Arming with the Remote Keyless Entry
Transmitter
The alarm system will arm when the remote keyless
entry transmitter is used to lock the doors after the
key is removed from the ignition. The red light will
come on to indicate that the system is arming. After
all doors are closed and locked, and after a time
delay, the red light will begin ashing at a very slow
rate to show the system is armed.
Arming Conrmation
A red light located on top of the instrument panel,
towards the center of the vehicle and near the
windshield, will ash slowly to conrm when
the system is armed.
Disarming with the Remote Keyless
Entry Transmitter
The alarm system will disarm when the remote
keyless entry transmitter is used to unlock
the doors. The red light will go out to show that
the system is disarmed.
105

Disarming with Your Key
