Mercedes-Benz E300 child lock location: On the side of the door, near the door lock (latch), there is a small lever, which is the child lock. Here is some introduction about the child lock: 1. The function of the child lock is: when there are children sitting in the rear seats, it can prevent active and unaware children from opening the door during driving, avoiding accidents. 2. If a car door cannot be opened from the inside and can only be opened from the outside, it is very likely that the child lock was activated by rear passengers when getting on or off the car. Simply reset the child lock to open the door from the inside.

Hi, I'm a seasoned driver with years of experience. I distinctly remember that the child lock on the Mercedes-Benz E300 is located on the inner side of the rear door, usually near the handle where there's a small keyhole. You need to insert the car key and turn it to lock, so kids can't open the door from the inside. This feature is super important for safe driving, especially when I take my little nephew for a ride. On the highway, if he accidentally plays with the door handle, the risk is huge! So, I always check before getting in the car—both rear doors have keyholes, so don’t miss either. Also, when parking, test if it’s locked; it’s a simple operation. Safety first, after all—Mercedes designed this to protect the whole family.
