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" in DIC 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 flashing 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 flash
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 flashing at a very slow
rate to show the system is armed.
Arming Confirmation
A red light located on top of the instrument panel,
towards the center of the vehicle and near the
windshield, will flash slowly to confirm 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.
