Wa r n i n g !
The seat belts provide protection only with the
backrest locked in place and, therefore, must be
locked in place with the vehicle in motion. Do not
drive the vehicle when the backrest is not locked in
place. If the warning message “SEAT BACKREST,
LEFT – LOCK!” or “SEAT BACKREST, RIGHT –
LOCK!” is displayed in the multifunction display,
then the respective backrest is not engaged in its
lock. Carefully slow down, and drive with caution
to an area which is in a safe distance from the
roadway. Always provide sufficient room behind
the backrest and fold the backrest all the way back
until it locks in place.The warning message is no longer displayed as
soon as the backrest is locked in place. If both
backrests are locked in place and the warning
message is still displayed, have the system checked
at your authorized Mercedes-Benz Center
immediately.
