Warning!
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 warn-
ing message
SEAT BACKREST, RIGHT -
LOCK
or
SEAT BACKREST, LEFT - 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 back-
rest all the way back until it locks in place.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
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 Mer-
cedes-Benz Center immediately.
When leaving the vehicle, always remove the
electronic key from the starter switch, take
the KEYLESS-GO* card with you, and lock
your vehicle.
