Ford F-450 (2017 year). Manual — part 9

E146365

The fully inflated belt's increased diameter
more effectively holds the occupant in the
appropriate seating position, and spreads
crash forces over more area of the body
than regular seatbelts. This helps reduce
pressure on the chest and helps control
head and neck motion for passengers.

WARNING

If the rear inflatable seatbelt has
deployed, it will not function again.
The rear inflatable seatbelt system

must be replaced by an authorized dealer.

The rear inflatable seatbelts are designed
to inflate in frontal or near-frontal crashes,
rollovers and some side impact crashes.
The fact that the rear inflatable seatbelt
did not inflate in a crash does not mean
that something is wrong with the system.
Rather, it means the forces were not of the
type sufficient to cause activation.

SEATBELT HEIGHT
ADJUSTMENT

WARNING

Position the safety belt height
adjuster so that the belt rests across
the middle of your shoulder. Failure

to adjust the safety belt properly could
reduce the effectiveness of the safety belt
and increase the risk of injury in a crash.

E145664

Adjust the height of the shoulder belt so
the belt rests across the middle of your
shoulder.

To adjust the shoulder belt height:

1.

Pull the button and slide the height
adjuster up or down.

2. Release the button and pull down on

the height adjuster to make sure it is
locked in place.

safely belted and surviving an accident.
We recommend you leave the system
activated for yourself and others who may
use the vehicle. To reduce the risk of injury,
do not deactivate or activate the system
while driving the vehicle.

CHILD RESTRAINT AND
SEATBELT MAINTENANCE

Inspect the vehicle safety belts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
seat safety belts to make sure there are no
nicks, tears or cuts. Replace if necessary.
All vehicle safety belt assemblies, including
retractors, buckles, front safety belt buckle
assemblies, buckle support assemblies
(slide bar-if equipped), shoulder belt
height adjusters (if equipped), shoulder
belt guide on seat back (if equipped), child
safety seat LATCH and tether anchors, and
attaching hardware, should be inspected
after a crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint.

Ford Motor Company recommends that
all safety belt assemblies in use in vehicles
involved in a crash be replaced. However,
if the crash was minor and an authorized
dealer finds that the belts do not show
damage and continue to operate properly,
they do not need to be replaced. Safety
belt assemblies not in use during a crash
should also be inspected and replaced if
either damage or improper operation is
noted.

Properly care for safety belts. See Vehicle
Care (page 360).

SEATBELT EXTENSION

WARNINGS

Persons who fit into the vehicle's
seatbelt should not use an extension.
Unnecessary use could result in

serious personal injury in the event of a
crash.

Only use extensions provided free of
charge by Ford Motor Company
dealers. The dealer will provide an

extension designed specifically for this
vehicle, model year and seating position.
The use of an extension intended for
another vehicle, model year or seating
position may not offer you the full
protection of your vehicle’s seatbelt
restraint system.

Never use seatbelt extensions to
install child restraints.

Do not use a seatbelt extension with
an inflatable seatbelt.

Do not use extensions to change the
fit of the belt across the torso, over
the lap or to make the seatbelt

buckle easier to reach.

If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
Ford Motor Company dealers. Only Ford
seatbelt extensions made by the original
equipment seatbelts manufacturer should
be used with Ford seatbelts. Ask your
authorized dealer if your extension is
compatible with your Ford vehicle restraint
system.
