Disarming The System; Triggering The Anti-Theft System - Ford 2012 Mustang Owner's Manual

Locks and Security
The turn signal lamps will flash once when all doors, the hood and the
trunk are closed indicating the vehicle is locked and entering the
20 second countdown. If any closure is not properly closed the turn
signal lamps will not flash and that closure will not be armed.

Disarming the system

You can disarm the system by any of the following actions:
• Unlock the doors by using the remote entry transmitter portion of
your integrated keyhead transmitter.
• Turn ignition to the on position with a valid programmed SecuriLock
key or integrated keyhead transmitter (IKT).
• Press the panic control on the remote entry transmitter portion of
your IKT. This will only shut off the horn and turn lamps when the
alarm is sounding. The alarm system will still be armed.
• Use a key in the driver's door to unlock the vehicle.
Pressing the power door unlock control within the 20 second prearmed
mode will return the vehicle to a disarmed state.
Note: Unlocking the trunk inhibits the motion sensing system but the
system continues to monitor the doors, hood and vehicle incline. Once
the trunk becomes closed the motion sensing system will rearm.

Triggering the anti-theft system

The armed system will be triggered if:
• Any door, the hood or the trunk is opened without using the remote
entry transmitter portion of your IKT or key in driver door cylinder.
• The ignition is turned to the on position with an invalid
unprogrammed SecuriLock key or IKT.
• The vehicle is towed/inclined.
• Motion is detected in the interior passenger compartment.
