Perimeter Lighting
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The perimeter lighting feature illuminates the exterior of the vehicle while the user approaches and enters the vehicle to provide better visibility to the user.
The perimeter lighting feature requests the headlamps and parking/position lamps to be on when the key is in the OFF position and the customer activates an external unlock feature (remote transmitter, keyless entry keypad, door lock cylinder). The perimeter lighting feature requests the headlamps and park/position lamps to be off when 25 seconds have elapsed since the last external unlock activation, or the customer activates an external lock feature (remote transmitter, keyless entry keypad), or the key is cycled to a position other than OFF.
