Warning!G
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed 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.
For your protection, drive only with properly
positioned and engaged head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level. This will reduce the po-
tential for injury to the head and neck in the
event of an accident or similar situation.
!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 Light Truck Center.
