Where is the child lock on the Mercedes-Benz E300?

[DelHarley]

On the side of the door, near the door lock, there is a small lever. This small lever is the child lock. Function of the car child safety lock: It is a feature designed to prevent children from accidentally opening the car door, which could cause harm to them. Generally, child locks are located on the two rear doors. When the child lock function is activated, the rear door cannot be opened from the inside but can still be opened from the outside. When the child lock function is deactivated, the door can be opened from both the inside and outside. This function is particularly necessary when the car is moving at high speed. If a child accidentally opens the door, the consequences could be dire. Most modern cars are equipped with this feature. Two types of child safety locks: There are two common types of child safety lock switches: one is a rotary type, and the other is a toggle type. The rotary child safety lock requires a key (or key-like object) to be inserted into the corresponding hole to turn the rotary switch for locking and unlocking operations. In comparison, the toggle-type child safety lock is more convenient to use.
