Your vehicle is equipped with head restraints
in all seating positions.
Head restraints are most effective for
protection against whiplash and other rear-
impact crash injuries when the center of the
back of the occupant's head rests against the
center of the restraint. The tops of the
occupant's ears should be level with the
center height of the restraint.

Make sure head restraints are in place and
positioned properly before driving.
