Why can't the Mercedes-Benz car door be opened from the inside but can be opened from the outside?

Mercedes-Benz car door cannot be opened from the inside but can be opened from the outside due to the child lock being activated. Here is a detailed introduction to the child lock: 1. Usage: When the child safety lock is needed, open the rear door, pull the small lever below the door lock towards the direction with the child icon, and then close the door. 2. Function: When the child safety device is in the locked state, the door can only be opened from the outside, and the inner door handle temporarily loses its function of opening the door. When the car child safety lock is in the locked state, even if the central lock is unlocked, it will still remain locked and can only be opened from the outside.
