52 Seats and Restraints
Head Restraints
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
If your vehicle has rear head
restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.
Front Seats
The vehicle's front seats have
adjustable head restraints in the
outboard seating positions.
The height of the head restraint can
be adjusted.
To raise or lower the head restraint,
press the button located on the side
of the head restraint, and pull up or
push the head restraint down and
release the button. Pull and push on
the head restraint after the button is
released to make sure that it is
locked in place.
The front seat outboard head
restraints are not removable.
Rear Seats
