Section 1 Seats and Restraint System
1-1

Head Restraints
The front seats have adjustable head restraints in the
outboard seating positions.
{CAUTION:
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.
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.
1-2

restraint, press the button, located on the top of the
seatback, and push the restraint down.
Push down on the head restraint after the button is
released to make sure that it is locked in place.
The head restraints are not designed to be removed.
The rear seat has head rests that can be adjusted
up and down.

you could go into it, receiving neck or other
injuries.
CAUTION: (Continued)
1-8

CAUTION: (Continued)
The lap belt cannot do its job either. In a crash the

forces would be there, not at your pelvic bones.
This could cause serious internal injuries.

motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.
Do not have a seatback reclined if the vehicle is
moving.
