SECURILOCK ி PASSIVE ANTI-THEFT SYSTEM
SecuriLock
௢ passive anti-theft system is an engine immobilization
system. This system prevents the engine from being started unless a
coded key programmed to your vehicle is 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.
Automatic arming
The vehicle is armed immediately
after switching the ignition to the 3
(OFF) position. The
THEFT light in
the instrument cluster will flash
every two seconds when the vehicle
is armed.
Automatic disarming
Switching the ignition to the 4 (ON) position with a coded key disarms
the vehicle. The
THEFT light will illuminate for three seconds and then
go out. If the THEFT light stays on for an extended period of time or
flashes rapidly, have the system serviced by your dealership or a
qualified technician.
