back of the head at eye level. This will
reduce the potential for injury to the head

similar situation.

move the respective head restraint up from
the lowest non-use position and have the
occupant adjust the head restraint
properly.

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

serious or even fatal injuries. Rear seat
occupants can be seriously injured or
killed.
