Lumbar Support - Mercedes-Benz 2009 M-Class Operator's Manual

Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the
occupant adjust the head restraint
properly.
! Do not attempt to remove front seat head
restraints. They can only be removed by
qualified technicians. We recommend that
you have this work carried out by an
authorized Mercedes-Benz Center.
