Driver's Seat Height Adjustment
The height of your driver's seat is
adjustable. To raise the seat,
repeatedly pull up the lever on the
outside of the seat cushion. To lower
the seat, push the lever down
repeatedly.
Head Restraints
See page 13 for important safety
information and a warning about how to
properly position the head restraints.
Your vehicle is equipped with head
restraints in all seating positions to
help protect you and your
passengers 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.
