How to enable automatic locking for Audi A6?

[Mason]

Audi A6's automatic locking activates when the speed exceeds approximately 20 km/h, automatically securing the doors. Below are details about the automatic locking feature: 1. The doors will not lock automatically after exiting the vehicle. Only after manually locking and then unlocking without opening any doors or performing any operations, the doors will automatically relock after about one minute. 2. The purpose of automatic locking is theft prevention. It quickly locks doors after driving begins, protecting passengers inside by preventing accidental opening of door handles during motion. 3. A drawback of automatic locking is that it may hinder escape in emergencies. The central locking system combines mechanical and electronic components. In case of an accident, electronic failure could prevent door opening, delaying escape and rescue opportunities. 4. To enhance active safety awareness, develop the habit of manually locking doors immediately after entering the vehicle before driving. Remember to unlock central locking when transitioning from complex urban roads to ring roads, closed roads, expressways, or highways.
