Backrest
Folding forward:
Lift lever and fold forwards.
Folding back:
Fold backrest back until it audibly locks 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.
Always provide sufficient room behind the backrest and 
fold the backrest all the way back until it can be heard 
locking in place.
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.

Wa r n i n g
The seat belts provide protection only with the 
backrest locked in place and, therefore, it must be 
locked in place with the vehicle in motion. Do not 
drive the vehicle when the backrest is not locked in 
place.
