1. Unlock.
2. Blocking.
If a lock is made in one of the door locks, in the tailgate lock or in the inside door handle, all doors are automatically locked. Unlocking is also carried out in the door lock or in the inside handle. If automatic unlocking occurs after locking, then at least one door is not properly closed. If re-locking is performed within 5 seconds, then all closed doors are then locked. The central locking indicates the locking of the car with one or more open doors in a special functional sequence (lock, unlock, lock). An open door is automatically locked after closing.
