1Head restraint
2Release button
Warning!G
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
With a third-row 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 in such a way 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 potential 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.
