FORD F-150 2019 Service Manual

PRINCIPLE OF OPERATION
WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips. WARNING:
To reduce the risk of
injury, make sure children sit where they
can be properly restrained. WARNING:
Never let a passenger
hold a child on his or her lap while the
vehicle is moving. The passenger cannot
protect the child from injury in a crash,
which may result in serious injury or
death. WARNING:
All occupants of the
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:
It is extremely
dangerous to ride in a cargo area, inside
or outside of a vehicle. In a crash, people
riding in these areas are more likely to be
seriously injured or killed. Do not allow
people to ride in any area of your vehicle
that is not equipped with seats and
safety belts. Be sure everyone in your
vehicle is in a seat and using a safety belt
properly. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
safety belt. WARNING:
Each seating position
in your vehicle has a specific safety belt
assembly which is made up of one
buckle and one tongue that are designed
to be used as a pair. 1) Use the shoulder
belt on the outside shoulder only. Never
wear the shoulder belt under the arm. 2)
Never swing the safety belt around your
neck over the inside shoulder. 3) Never
use a single belt for more than one
person. WARNING:
When possible, all
children 12 years old and under should
be properly restrained in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or
death. WARNING:
Safety belts and seats
can become hot in a vehicle that has
been closed up in sunny weather; they
could burn a small child. Check seat
covers and buckles before you place a
child anywhere near them. WARNING:
Front and rear seat
occupants, including pregnant women,
should wear safety belts for optimum
protection in an accident.
All seating positions in this vehicle have
lap and shoulder safety belts. All
occupants of the vehicle should always
properly wear their safety belts, even when
an airbag supplemental restraint system
is provided.
The safety belt system consists of:
• Lap and shoulder safety belts.
• Shoulder safety belt with automatic
locking mode, (except driver safety
belt).

•
Height adjuster at the front outboard
seating positions.
• Safety belt pretensioner at the front
outboard seating positions. •
Safety belt warning light and chime. •
Crash sensors and monitoring system
with readiness indicator.
The safety belt pretensioners at the front
seating positions are designed to tighten
the safety belts when activated. In frontal
and near-frontal crashes, the safety belt
pretensioners may be activated alone or,
if the crash is of sufficient severity, together
with the front airbags. In side crashes and
rollovers, the pretensioners will be
activated when the Safety Canopy is
activated.
FASTENING THE SEATBELTS
Standard belts shown, inflatable belts
similar
The front outermost 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)
The cinch tongue slides up and down the
seatbelt webbing when you stow the belt
or when you put the 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.

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. The front outermost 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
restraint in a front outermost 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 20).
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.
41
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201808, Third-Printing- SeatbeltsE142591

Rear Outermost Inflatable Seatbelts
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 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 outermost seating positions.
Note:
The rear inflatable seatbelts are
compatible with most infant and child
restraints 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.
42
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201808, Third-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 65). 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 switches 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
the procedure within 30 seconds.

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 377).
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 our 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 way the seatbelt fits
across the torso, over the lap or to make
the seatbelt buckle easier to reach.
