The function in the locking system for locks with deadlocking is the same as in the standard locking system. There is an extra lock motor in the lock units for the deadlocking function. The function of this lock motor is to mechanically disconnect the lock unit in the door from the door handles. The function is normally activated automatically 25 seconds after the vehicle has been locked and the last door closed. This means for example that a side door cannot be opened even if a window is broken.

NOTE:

This also means that anybody remaining in the vehicle when it is locked cannot leave. The function can be temporarily disconnected with the switch for reduced alarm which is located on the dashboard environment panel.
