PERIMETER ALARM SYSTEM (IF EQUIPPED)
The perimeter anti-theft system will warn you in the event of an
unauthorized entry to your vehicle.
If there is any potential perimeter anti-theft problem with your vehicle,
ensure ALL remote entry transmitters are taken 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
park/turn lamps and will sound the horn.
The system is ready to arm whenever the key is removed from the
ignition. Either of the following actions will prearm the alarm system:
• Press the
control on the remote entry transmitter.
• Open a door and press the power door lock control to lock all the
doors, and then close the door.
• Press and hold the 7 • 8 and 9 • 0 controls on the keyless entry pad
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 and the hood is armed individually, and if any are open, they
must be closed before the open entry point can enter the 20 second
countdown.
The turn signal lamps will flash once when all doors and the hood are
closed indicating the vehicle is locked and entering the 20 second
countdown.
