Seats and Restraint System 1-1

Head Restraints

head restraints in the outboard
seating positions.

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.Pull the head restraint up to raise it.
To lower the head restraint, press
the button, located on the top of
the seatback, and push the
restraint down.

Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even if when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its job
because it will not be against your
body. Instead, it will be in front of
you. In a crash, you could go into
it, receiving neck or other injuries.
(Continued)
CAUTION (Continued)
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen. The
belt forces would be there, not at
your pelvic bones. This could
cause serious internal injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Do not have a seatback reclined
when the vehicle is moving.
