Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.!Do not attempt to remove front seat
head restraints. They can only be re-
moved by qualified technicians. We
recommend that you have this work
carried out by an authorized
Mercedes-Benz Light Truck Center.
