How to Use an E320 Child Door Lock

1. Open the driver's side back door of the Mercedes-Benz E320.
2. Locate the child door lock. It is on the edge of each back door and can only be accessed when the car door is open. It will appear as a small latch that moves up and down. Lower the latch to activate the locking feature. Lift the latch to deactivate the feature.
3. Repeat the process on the passenger-side back door.
