PERIMETER ALARM SYSTEM
The perimeter anti-theft system will help protect your vehicle from
unauthorized entry.
If there is any potential perimeter anti-theft problem with your vehicle,
ensureALL Integrated Keyhead Transmittersare brought to the
authorized dealer to aid in troubleshooting.
Arming the system
When armed, this system will respond if unauthorized entry is
attempted. When unauthorized entry occurs, the system will flash the
turn signal lamps and will sound the horn.
The system is ready to arm whenever the key is in the 1(LOCK)
position, or is removed from the ignition. Either of the following actions
will prearm the alarm system:
•Press the
control on the remote entry transmitter portion of your
Integrated Keyhead Transmitter.
When you press the lock control twice within three seconds on the
remote entry transmitter portion of your IKT, the horn will chirp once
to let you know that all doors, the hood and the liftgate are closed. If
any of these are not closed, the horn will chirp twice to warn you that
a door, the hood or the liftgate is still open.
•Press the driver or passenger
interior door lock control while
the door is open, then close the
door.
•Press the 7•8 and 9•0
controls on the keyless entry pad
(if equipped) at the same time to
lock the doors (driver’s door must
be closed).
There is a 20 second countdown when any of the above actions occur
before the vehicle becomes armed.

Each door, the hood, and the liftgate is armed individually, and if any are
open, they must be closed before the open entry point (door, hood, or
liftgate) can enter the 20 second countdown.
The turn signal lamps will flash once when all doors, the hood and the
liftgate are closed indicating the vehicle is locked and entering the 20
second countdown.
Disarming the system
You can disarm the system by any of the following actions:
•Unlock the doors by using the remote entry transmitter portion of
your Integrated Keyhead Transmitter.
•Unlock the doors by using your keyless entry pad (if equipped).
•Unlock the driver’s door with a key. Turn the key full rearward
(toward the rear of the vehicle) to ensure the alarm disarms.
•Turn ignition to the 3 (ON) position with a valid SecuriLock™ key or
Integrated Keyhead Transmitter (IKT).
•Press the panic control on the remote entry transmitter portion of
your IKT. This will only shut off the horn and turn lamps when the
alarm is sounding. The alarm system will still be armed.
Pressing the power door UNLOCK control within the 20 second
prearmed mode will return the vehicle to a disarmed state.
Triggering the anti-theft system
The armed system will be triggered if:
•Any door, the hood or the liftgate is opened without using the door
key, keypad or the remote entry transmitter portion of your IKT.
•The ignition is turned to the 3 (ON) position with an invalid
SecuriLock™ key or IKT.
