PASSIVE ANTI-THEFT
SYSTEM
Note:
The 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.
Note: Metallic objects, electronic devices
or a second coded key on the same key
chain may cause vehicle starting problems
if they are too close to the key when starting
your vehicle. Prevent these objects from
touching the coded key while starting your
vehicle. Switch the ignition off, move all
objects on the key chain away from the
coded key and restart your vehicle if a
problem occurs.
Note: Do not leave a duplicate coded key
in your vehicle. Always take your keys and
lock all doors when leaving your vehicle.
SecuriLock
The system helps prevent your vehicle
from starting unless you use a coded key
programmed to your vehicle. Using the
wrong key may prevent your vehicle from
starting. A message may appear in the
information display.
If you are unable to start your vehicle with
a correctly coded key, it is not operating
properly. A message may appear in the
information display.
Automatic Arming
Your vehicle arms immediately after
switching the ignition off.
Automatic Disarming
Switching the ignition on with a coded key
disarms your vehicle. Replacement Keys
Note:
Your vehicle comes equipped with
two intelligent access keys.
The intelligent access key functions as a
programmed key that operates the driver
door lock and activates the intelligent
access with push button start system, as
well as a remote control.
If your programmed transmitters are lost
or stolen and you do not have an extra
coded key, you need to have your vehicle
towed to an authorized dealer. You need
to erase the key codes from your vehicle
and program new coded keys.
Store an extra programmed key away from
your vehicle in a safe place to help prevent
any inconveniences. See your authorized
dealer to purchase additional spare or
replacement keys.
Programming a Spare Intelligent
Access Key
Note: You can program a maximum of four
intelligent access keys to your vehicle.
You must have two previously
programmed intelligent access keys inside
your vehicle and the new unprogrammed
intelligent access keys readily accessible.
See an authorized dealer to have the spare
key programmed if two previously
programmed keys are not available.
Make sure that your vehicle is off before
beginning this procedure. Make sure that
you close all the doors before beginning
and that they remain closed throughout
the procedure. Perform all steps within 30
seconds of starting the sequence. Stop
and wait for at least one minute before
starting again if you perform any steps out
of sequence.
Read and understand the entire procedure
before you begin.
