are occupied. Head restraints are intended
to help reduce injuries during an accident.

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

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 re-
duce the potential for injury to the head and
