3-2 Seats and Restraints
Head Restraints
The 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.
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.
Push down on the head restraint
after the button is released to make
sure that it is locked in place.

when the vehicle is moving.
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even 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.
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.

the seat heater, especially for
long periods of time. Do not
place anything on the seat that
