FORD F450 SUPER DUTY 2018 Service Manual

The seatbelt pretensioners at the front
seating positions are designed to tighten
the seatbelts when activated. In frontal
and near-frontal crashes, the seatbelt
pretensioners may be activated alone or,
if the crash is of sufficient severity, together
with the front airbags. In side crashes and
rollovers, the seatbelt pretensioners
activate when the Safety Canopy is
activated.
FASTENING THE SEATBELTS
Standard belts shown, inflatable belts
similar
The front outboard and rear safety
restraints in the vehicle are combination
lap and shoulder belts.
1. Insert the belt tongue into the proper
buckle (the buckle closest to the
direction the tongue is coming from)
until you hear a snap and feel it latch.
Make sure you securely fasten the
tongue in the buckle. 2. To unfasten, press the release button
and remove the tongue from the
buckle.
Using the Seatbelt with Cinch
Tongue (Front Center Seat on
Super Cab and Crew Cab)
The cinch tongue slides up and down the
belt webbing when you stow the belt or
while putting seatbelts on. When you
buckle the lap and shoulder seatbelt, the
cinch tongue allows you to shorten the lap
portion, but pinches the webbing to keep
the lap portion from getting longer. The
cinch tongue is designed to slip during a
crash, so always wear the shoulder belt
properly and do not allow any slack in
either the lap or shoulder portions.
Before you can reach and latch a lap and
shoulder belt having a cinch tongue into
the buckle, you may have to lengthen the
lap belt portion of it.
38

1. To lengthen the lap belt, pull some
webbing out of the shoulder belt
retractor.
2. While holding the webbing below the tongue, grasp the tip (metal portion)
of the tongue so that it is parallel to the
webbing and slide the tongue upward.
3. Provide enough lap belt length so that
the tongue can reach the buckle.
Fastening the Cinch Tongue WARNING
Always drive and ride with your
seatback upright and the lap belt
snug and low across the hips.
1.
Pull the lap and shoulder belt from the
retractor so that the shoulder belt
portion of the seatbelt crosses your
shoulder and chest.
2. Be sure the belt is not twisted. If the belt is twisted, remove the twist.
3. Insert the belt tongue into the proper buckle for your seating position until
you hear a snap and feel it latch.
4. Make sure you securely fasten the tongue to the buckle by pulling on the
tongue. While you are fastened in the seatbelt, the
lap and shoulder belt with a cinch tongue
adjusts to your movement. However, if you
brake hard, turn hard, or if your vehicle
receives an impact of 5 mph (8 km/h) or
more, the seatbelt will become locked and
help reduce your forward movement.
Using Seatbelts During Pregnancy WARNING
Always ride and drive with your
seatback upright and properly fasten
your seatbelt. Fit the lap portion of
the seatbelt snugly and low across the
hips. Position the shoulder portion of the
seatbelt across your chest. Pregnant
women must follow this practice. See the
following figure. Pregnant women should always wear their
seatbelt. Position the lap belt portion of a
combination lap and shoulder belt low
across the hips below the belly and worn
as tight as comfort allows. Position the
shoulder belt to cross the middle of the
shoulder and the center of the chest.

Seatbelt Locking Modes
WARNING
If your vehicle is involved in a crash,
have the seatbelts and associated
components inspected as soon as
possible. Failure to follow this instruction
could result in personal injury or death. All safety restraints in the vehicle are
combination lap and shoulder belts. The
driver seatbelt has the first type of locking
mode, and the front outboard passenger
and rear seat seatbelts have both types of
locking modes described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which
allows free shoulder belt length
adjustment to your movements and
locking in response to vehicle movement.
For example, if the driver brakes suddenly,
turns a corner sharply, or the vehicle
receives an impact of about 5 mph
(8 km/h) or more, the combination
seatbelts lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock
if you pull the webbing out too quickly. If
the seatbelt retractor locks, slowly lower
the height adjuster to allow the seatbelt
to retract. If the retractor does not unlock,
pull the seatbelt out slowly then feed a
small length of webbing back toward the
stowed position. For rear seatbelts, recline
the rear seat backrest or push the seat
backrest cushion away from the seatbelt.
Feed a small length of webbing back
toward the stowed position.
Automatic Locking Mode
In this mode, the shoulder belt
automatically pre-locks. The belt still
retracts to remove any slack in the
shoulder belt. The automatic locking mode
is not available on the driver seatbelt. When to Use the Automatic Locking
Mode
Use this mode any time you install a child
safety seat in a front outboard passenger
seating position in a Regular Cab,
SuperCab, SuperCrew or any rear seating
position of a SuperCab or SuperCrew. The
optional front seat's center seatbelt has a
cinch mechanism. Properly restrain
children 12 years old and under in a rear
seat whenever possible. See
Child Safety
(page 19).
How to Use the Automatic Locking
Mode
Non-inflatable seatbelts 1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and pull downward until you pull the entire belt
out.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking sound.
This indicates the seatbelt is now in the
automatic locking mode.
40
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, First Printing SeatbeltsE142591

Rear outboard inflatable seatbelts
(second row only
– if equipped)1. Buckle the combination lap and
shoulder belt.
2. Grasp the lap portion of the belt and pull upward until you pull the entire
belt out.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking sound.
This indicates the seatbelt is now in the
automatic locking mode.
How to Disengage the Automatic
Locking Mode
Unbuckle the combination lap and
shoulder belt and allow it to retract
completely to disengage the automatic
locking mode and activate the vehicle
sensitive (emergency) locking mode.
Rear Inflatable Seatbelt (If Equipped) WARNING
Do not attempt to service, repair, or
modify the supplementary restraint
system or associated components.
Failure to follow this instruction could
result in personal injury or death. The rear inflatable seatbelts are in the
shoulder portion of the seatbelts of the
second-row outboard seating positions.
Note:
The rear inflatable seatbelts are
compatible with most infant and child
safety car seats and belt positioning booster
seats when properly installed. This is
because they are designed to fill with a
cooled gas at a lower pressure and at a
slower rate than traditional airbags. After
inflation, the shoulder portion of the
seatbelt remains cool to the touch.
The rear inflatable seatbelt consists of the
following:
• An inflatable bag in the shoulder
seatbelt webbing.
• Lap seatbelt webbing with automatic
locking mode.
• The same warning light, electronic
control and diagnostic unit as used for
the front seatbelts.
• Impact sensors in various parts of the
vehicle.
How does the rear inflatable seatbelt
system work? WARNING
If a supplementary restraint system
component has deployed, it will not
function again. Have the system and
associated components inspected as soon
as possible. Failure to follow this
instruction could result in personal injury
or death. The rear inflatable seatbelts function like
standard restraints in everyday usage.
41
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, First Printing SeatbeltsE146363

During a crash of sufficient force, the
inflatable belt inflates from inside the
webbing.
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.
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. 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.
SEATBELT WARNING LAMP
AND INDICATOR CHIME This lamp illuminates and an
audible warning will sound if the
driver seatbelt has not been
fastened when the vehicle's ignition is
turned on.

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 371).

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.

PRINCIPLE OF OPERATION
WARNINGS
Airbags do not inflate slowly or
gently, and the risk of injury from a
deploying airbag is the greatest close
to the trim covering the airbag module. All occupants of your vehicle,
including the driver, should always
properly wear their safety belts, even
when an airbag supplemental restraint
system is provided. Failure to properly wear
your safety belt could seriously increase
the risk of injury or death. Always transport children 12 years
old and under in the back seat and
always properly use appropriate
child restraints. Failure to follow this could
seriously increase the risk of injury or death. Never place your arm over the airbag
module as a deploying airbag can
result in serious arm fractures or
other injuries. Airbags can kill or injure a child in a
child seat. Never place a rear-facing
child seat in front of an active airbag.
If you must use a forward-facing child seat
in the front seat, move the seat upon which
the child seat is installed all the way back. Do not attempt to service, repair, or
modify the airbag supplemental
restraint systems or its fuses as you
could be seriously injured or killed. Contact
your authorized dealer as soon as possible. Several airbag system components
get hot after inflation. To avoid risk
of injury, do not touch them after
inflation. If the airbag has deployed, the airbag
will not function again and must be
replaced immediately. If the airbag
is not replaced, the unrepaired area will
increase the risk of injury in a crash. The airbags are a supplemental restraint
system and are designed to work with the
safety belts to help protect the driver and
right front passenger from certain upper
body injuries. Airbags do not inflate slowly;
there is a risk of injury from a deploying
airbag.
Note:
You will hear a loud bang and see a
cloud of harmless powdery residue if an
airbag deploys. This is normal.
The airbags inflate and deflate rapidly
upon activation. After airbag deployment,
it is normal to notice a smoke-like, powdery
residue or smell the burnt propellant. This
may consist of cornstarch, talcum powder
(to lubricate the bag) or sodium
compounds (for example, baking soda)
that result from the combustion process
that inflates the airbag. Small amounts of
sodium hydroxide may be present which
may irritate the skin and eyes, but none of
the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with a
deploying airbag may also cause abrasions
or swelling. Temporary hearing loss is also
a possibility as a result of the noise
associated with a deploying airbag.
Because airbags must inflate rapidly and
with considerable force, there is the risk of
death or serious injuries such as fractures,
facial and eye injuries or internal injuries,
particularly to occupants who are not
properly restrained or are otherwise out of
position at the time of airbag deployment.
Thus, it is extremely important that
occupants be properly restrained as far
away from the airbag module as possible
while maintaining vehicle control.
Routine maintenance of the airbags is not
required.

DRIVER AND PASSENGER
AIRBAGS
WARNINGS
Never place your arm over the airbag
module as a deploying airbag can
result in serious arm fractures or
other injuries. Airbags can kill or injure a child in a
child restraint. Never place a
rear-facing child restraint in front of
an active airbag. If you must use a
forward-facing child restraint in the front
seat, move the seat upon which the child
seat is installed all the way back. The driver and front passenger airbags
deploy during significant frontal and near
frontal crashes.
The driver and passenger front airbag
system consists of:
•
Driver and passenger airbag modules. · Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag
Indicator (page 54). Passenger Airbag On and Off
Switch
(If Equipped) WARNINGS
Even with advanced restraints
systems, properly restrain children
12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or death. The front passenger airbag is not
designed to offer protection to an
occupant in the center seating
position. Your vehicle may have an airbag
deactivation switch. Before driving,
always look at the switch to make
sure it is in the appropriate position. Failure
to put the switch in the proper position can
increase the risk of serious injury or death
in a crash. High-series vehicles (if equipped)
The front passenger airbag on and off
switch has indicators that illuminate,
indicating that the front passenger frontal
airbag is either on or off. The indicator lamp
is near the center of the instrument panel.
Note:
The passenger airbag status indicator
OFF and ON lamps illuminate for a short
period of time when you switch the ignition
on to confirm it is functional.
