44 SEATS AND RESTRAINTS
Head Restraints
The vehicle’s front seats have
adjustable head restraints in the
outboard seating positions.
{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.
Pull the head restraint up to raise it.
Try to move the head restraint to
make sure that it is locked in place.
To lower the head restraint, press the
button located on top of the seatback,
and push the head restraint down. Try
to move the head restraint after the
button is released to make sure that it
is locked in place.
