SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine
immobilization system. This system is designed to
prevent the engine from being started unless a
coded key programmed to your vehicleis used.
The SecuriLock
passive anti-theft system is not
compatible with non-Ford aftermarket remote start
systems. Use of these systems may result in vehicle
starting problems and a loss of security protection.
THEFT INDICATOR
The theft indicator is the flashing red indicator
located on top of the instrument panel.
•When the ignition is in the OFF position, the
indicator will flash once every 2 seconds to
indicate the SecuriLock
system is functioning as
a theft deterrent.
•When the ignition is in the ON position, the
indicator will glow for 3 seconds to indicate
normal system functionality.
If a problem occurs with the SecuriLock
system,
the indicator will flash rapidly or glow steadily when
the ignition is in the ON position. If this occurs, the
vehicle should be taken to an authorized dealer for
service.
