FORD F-150 2018 Service Manual

1. To lengthen the lap belt, pull some
seatbelt 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 up.
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 locks and helps 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 center seatbelt has a
cinch mechanism. Properly restrain
children 12 years old and under in a rear
seat whenever possible. See
Child Safety
(page 18).
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.

F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201709, Fifth-Printing SeatbeltsE142591

Rear Outboard Inflatable Seatbelts
Second Row Only
– If Equipped1. 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.
40
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201709, Fifth-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
indicator chime will sound if the
driver seatbelt has not been
fastened when the vehicle's ignition is
turned on.

SEATBELT REMINDER
Belt-Minder™
This feature supplements the seatbelt
warning function by providing additional
reminders that intermittently sound a tone
and illuminate the seatbelt warning light
when you are in the driver seat or you have
a front seat passenger and a seatbelt is
unbuckled. The system uses information from the
front passenger sensing system to
determine if a front seat passenger is
present and therefore potentially in need
of a warning. To avoid activating the
Belt-Minder feature for objects you place
in the front passenger seat, only the front
seat passengers receive warnings as
determined by the front passenger sensing
system.
If the Belt-Minder warnings expire
(warnings for about five minutes) for one
passenger (driver or front passenger), the
other passenger can still cause the
Belt-Minder feature to turn on.

Deactivating and Activating the
Belt-Minder Feature WARNING: While the system
allows you to deactivate it, this system
is designed to improve your chances of
being safely belted and surviving an
accident. We recommend you leave the
system activated for yourself and others
who may use the vehicle.
Note: The driver and front passenger
warnings switch on and off independently.
When you perform this procedure for one
seating position, do not buckle the other
position as this will terminate the process.
Note: If you are using MyKey, you cannot
disable the Belt-Minder. Also, if the
Belt-Minder has been previously disabled,
it will be re-enabled during the use of
MyKey. See
MyKey ™ (page 63). Read Steps 1 - 4 thoroughly before
proceeding with the programming
procedure.
Before following the procedure, make sure
that:
•
The parking brake is set.
• The transmission is in park (P).
• The ignition is off.
• The driver and front passenger seatbelt
is unbuckled.
1. Switch the ignition on. Do not start the
engine.
2. Wait until the seatbelt warning light turns off (about one minute). After
Step 2, wait an additional 5 seconds
before proceeding with Step 3. Once
you start Step 3, you must complete

CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
restraint seatbelts to make sure there are
no nicks, tears or cuts. Replace if
necessary. All vehicle seatbelt assemblies,
including retractors, buckles, front seatbelt
buckle assemblies, buckle support
assemblies (slide bar-if equipped),
shoulder belt height adjusters (if
equipped), shoulder belt guide on seat
backrest (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. We recommend that all seatbelt
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. Seatbelt assemblies
not in use during a crash should also be
inspected and replaced if either damage
or improper operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 373).
SEATBELT EXTENSION WARNING:
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. WARNING:
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. WARNING:
Never use seatbelt
extensions to install child restraints. WARNING:
Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
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.

F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201709, Fifth-Printing Seatbelts

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.

The Personal Safety System provides an
improved overall level of frontal crash
protection to front seat occupants and is
designed to help further reduce the risk of
airbag-related injuries. The system is able
to analyze different occupant conditions
and crash severity before activating the
appropriate safety devices to help better
protect a range of occupants in a variety
of frontal crash situations.
The Vehicle Personal Safety System
consists of:
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front seat outboard seatbelts with
pretensioners, energy management
retractors and seatbelt usage sensors.
• Driver seat position sensor.
• Front passenger sensing system.
• Passenger airbag status indicator.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning lamp and
tone.
• The electrical wiring for the airbags,
crash sensors, seatbelt pretensioners,
front seatbelt usage sensors, driver
seat position sensor, front passenger
sensing system and indicator lights.
How Does the Personal Safety
System Work?
The Personal Safety System can adapt the
deployment strategy of the safety devices
according to crash severity and occupant
conditions. A collection of crash and
occupant sensors provides information to
the restraints control module. During a
crash, the restraints control module may
deploy the seatbelt pretensioners, one or
both stages of the dual-stage airbags
based on crash severity and occupant
conditions.

PRINCIPLE OF OPERATION
WARNING: 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. WARNING:
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. WARNING:
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. WARNING:
Never place your arm
over the airbag module as a deploying
airbag can result in serious arm fractures
or other injuries. WARNING:
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. WARNING:
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. WARNING:
Several airbag system
components get hot after inflation. To
avoid risk of injury, do not touch them
after inflation. WARNING:
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
