Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Door Latches
The door latches have two integral motors, which can be used to put the latch into three different mechanical states:
- Unlocked - doors can be opened from the inside or outside release handles.
- Central Lock (Single Lock) - doors can only be opened from the inside release handle.
- Central Arest (Double Lock) - doors cannot be opened from either handle.
Micro-switches for the door contacts are integrated in the door latches. On the driver's door latch assembly, the key lock/unlock micro-switches are also included.
The central locking motors can be driven directly from any mechanical state to any other mechanical state; there is no need to go via any intermediate states.
