Do not drive the vehicle when the backrest is not locked in place. Note: If the backrest and seat belt warning lamp < does not go out, but is instead lit continuously, then a backrest is not engaged in its lock.

The warning lamp goes out as soon as both backrests are locked in place. If both backrests are locked in place and the warning lamp does not go out, have the system checked at your authorized Mercedes-Benz Center immediately. Folding forward: Lift lever and fold forwards. Folding back: Fold backrest back until it audibly locks in place.
