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.
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 drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident. G
WARNING
Make sure the rear seat head restraints
engage when placing them upright manually.
Otherwise  their protective  function 
cannot be
ensured.
The back of the head will not be supported in
the event of a collision. That could cause
serious or even fatal injuries. Rear seat
occupants can be seriously injured or killed.
