Head Restraints
See page 12 for important safety
information and a warning about how to
properly position the head restraints.
The front head restraints help
protect you and your passenger from
whiplash and other injuries. They are
most effective when you adjust them
so the back of the occupant's head
rests against the center of the
restraint. A taller person should
adjust the restraint as high as
possible.
The head restraints adjust for height.
You need both hands to adjust the
restraint. Do not attempt to adjust it
while driving. To raise it, pull upward.
To lower the restraint, push the
release button sideways and push
the restraint down.
To remove a head restraint for
cleaning or repair, pull it up as far as
it will go. Push the release button
and pull the restraint out of the seat-
back.
