Power Locks: Description and Operation




- Unlike the previous system, which was pneumatically operated, the new generation central locking system operates using electric motors.
- The lock actuators in the doors are integrated in the lock and have 2 electric motors.
- The lock actuators cannot be replaced separately.
- The first electric motor locks the door and the second electric motor locks the interior door mechanism ("Safe" function).
- Locked doors can no longer be opened from inside the car.
- The lock actuators for the fuel filler flap and rear lid each have one electric motor, and can be replaced separately.
- After an accident involving activation of the airbag, the control module for central locking will unlock any active door locks.
- The control module for central locking is located inside a protective box in floor cavity beneath driver's seat and carpet, in front of floor pan crossmember.
