Perimeter Alarm System: Notes

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The convertible top (if equipped), the luggage compartment lid, and all doors must be closed for the interior motion sensing feature to activate.

NOTE: The perimeter alarm system includes a motion detection system that monitors the vehicle interior and a vehicle inclination sensor that detects changes in vehicle inclination.

NOTE: The inclination sensing feature must be disarmed before raising the vehicle on a hoist to prevent false alarms.

The anti-theft perimeter alarm feature is controlled by the SJB. The perimeter alarm system is designed to warn the driver in the event of an unauthorized entry to the vehicle and is also designed to help prevent the unwanted towing of the vehicle. When the vehicle is locked and armed, the perimeter alarm system monitors the following:

Doors
Hood
Luggage compartment lid
Movement inside the vehicle
Change in vehicle inclination/tilt

If unauthorized activation of the above inputs occurs, the system flashes the turn signals and sounds the anti-theft alarm horn and the traffic horns.

The interior motion detection and vehicle inclination sensing systems operate only when the vehicle is locked using the RKE transmitter or when using the door lock control switch with the accompanying door open and all the doors are then closed. For vehicles with a convertible top, the top must be in the fully closed and latched position for the interior motion sensing system to arm. If the vehicle is locked using the key in the driver door lock cylinder, the system monitors the doors, the luggage compartment lid and the hood, but the interior motion and the vehicle inclination sensing does not arm. Do not arm the interior motion detection system if movement within the vehicle is likely to occur. Do not arm the vehicle inclination sensing system when the vehicle is in transport. For correct operation of the interior motion detection system, make sure all the windows are closed prior to arming the system. This helps prevent accidental alarm activation due to external influences and makes sure that correct interior motion detection occurs. The interior motion sensing system does not arm if either door is ajar.
