FORD 2009 F-550 v.3 - Manual (Page 172)

SEATING
WARNING: Reclining the seatback can cause an occupant to
slide under the seat’s safety belt, resulting in severe personal
injuries in the event of a collision.
WARNING: Do not pile cargo higher than the seatbacks to
reduce the risk of injury in a collision or sudden stop.
WARNING: Before returning the seatback to its original
position, make sure that cargo or any objects are not trapped
behind the seatback. After returning the seatback to its original
position, pull on the seatback to ensure that it has fully latched. An
unlatched seat may become dangerous in the event of a sudden stop or
collision.
Non-adjustable head restraints
Your vehicle is equipped with front row outboard non-adjustable head
restraints.
WARNING: To minimize the risk of neck injury in the event of a
crash, the driver and passenger occupants should not sit in
and/or operate the vehicle, until the seatback is placed in its proper
position. The driver should never adjust the seatback while the vehicle
is in motion.
The non-adjustable head restraints
consist of a trimmed foam covering
over the upper structure of the
seatback.
Properly adjust the seatback to an upright driving/riding position, so that
the head restraint is positioned as close as possible to the back of your
head.
