50 Seats and Restraints
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.
To raise or lower the head restraint,
press the button 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
The vehicle's rear seats have
adjustable head restraints in the
outboard seating positions.
The height of the head restraint can
be adjusted. 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 on the 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.
