potential for injury to the head and neck in the
event of an accident or similar situation.
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.

restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident.
