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 382).
SEATBELT EXTENSIONS 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.

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 seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Properly secure
children 12 years old and under in a rear
seating position whenever possible. If
you are unable to properly secure all
children in a rear seating position,
properly secure the largest child on the
front seat. If you must use a forward
facing child restraint on the front seat,
move the seat as far back as possible.
Failure to follow these instructions could
result in personal injury or death. WARNING:
Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury. WARNING:
Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. 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. WARNING:
Several airbag system
components get hot after inflation. To
reduce the risk of injury, do not touch
them after inflation. 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 airbags are a supplemental restraint
system and are designed to work with the
seatbelts 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,
51
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Supplementary Restraints System

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
WARNING: Keep the areas in front
of the airbags free from obstruction. Do
not affix anything to or over the airbag
covers. Objects could become projectiles
during airbag deployment. Failure to
follow this instruction could result in
personal injury or death. WARNING:
Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. WARNING:
Properly secure
children 12 years old and under in a rear
seating position whenever possible. If
you are unable to properly secure all
children in a rear seating position,
properly secure the largest child on the
front seat. If you must use a forward
facing child restraint on the front seat,
move the seat as far back as possible.
Failure to follow these instructions could
result in personal injury or death. The driver and front passenger airbags will
deploy during significant frontal and near
frontal crashes.
The driver and passenger front airbag
system consists of:
•
Driver and passenger airbag modules.
• Front passenger sensing system.
• Crash sensors and monitoring system
with readiness indicator. See
Crash
Sensors and Airbag Indicator (page
58
).
Proper Driver and Front Passenger
Seating Adjustment WARNING:
National Highway
Traffic Safety Administration (NHTSA)
recommends a minimum distance of at
least
10 in (25 cm) between an
occupant's chest and the driver airbag
module.
To properly position yourself away from
the airbag:
• Move your seat to the rear as far as you
can while still reaching the pedals
comfortably.
• Recline the seat slightly one or two
degrees from the upright position.

After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit
properly. Properly seated occupants sit
upright, lean against the seat backrest, and
center themselves on the seat cushion,
with their feet comfortably extended on
the floor. Sitting improperly can increase
the chance of injury in a crash event. For
example, if an occupant slouches, lies
down, turns sideways, sits forward, leans
forward or sideways, or puts one or both
feet up, the chance of injury during a crash
greatly increases.
Children and Airbags
WARNING: Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. Children must always be properly
restrained. Accident statistics suggest that
children are safer when properly restrained
in the rear seating positions than in the
front seating position. Failure to follow
these instructions may increase the risk of
injury in a crash. If two adults and a child occupy a Regular
Cab, properly restrain the child in the
center front seat unless doing so would
interfere with driving your vehicle. This
provides lap and shoulder belt protection
for all occupants, and airbag protection for
the adults. A child or infant properly
restrained in the center front seat should
not incur risk of serious injury from the
airbags.
FRONT PASSENGER SENSING
SYSTEM
WARNING:
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. WARNING:
Sitting improperly, out
of position or with the seatback reclined
too far can take weight off the seat
cushion and affect the decision of the
passenger sensing system, resulting in
serious injury or death in the event of a
crash. Always sit upright against your
seat back, with your feet on the floor. WARNING:
Any alteration or
modification to the front passenger seat
may affect the performance of the front
passenger sensing system. This could
seriously increase the risk of injury or
death. 53
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Supplementary Restraints SystemE142846 E181984

The front passenger sensing system uses
a passenger airbag status indicator which
illuminates indicating that the front
passenger frontal airbag is either on
(enabled) or off (disabled). The indicator
lamp is in the center stack of the
instrument panel.
Note:
When you first switch the ignition on,
the passenger airbag status indicator off
and on lamps illuminate for a short period
to confirm they are functional.
The front passenger sensing system is
designed to disable (will not inflate) the
front passenger frontal airbag under
certain conditions:
• The front passenger seat is
unoccupied.
• The system determines an infant is
present in a child restraint.
• A passenger takes their weight off of
the seat for a period of time.
• If there is a problem with the airbag
system or the passenger sensing
system.
Even with this technology, parents are
strongly encouraged to always properly
restrain children in the rear seat.
• When the front passenger sensing
system disables (will not inflate) the
front passenger frontal airbag, the
passenger airbag status indicator
illuminates the off lamp and stays lit
to remind you that the front passenger
frontal airbag is disabled.
• If you have installed the child restraint
and the passenger airbag status
indicator illuminates the on lamp, then
switch your vehicle off, remove the
child restraint from your vehicle and
reinstall the restraint following the
child restraint manufacturer's
instructions. The front passenger sensing system works
with sensors that are part of the front
passenger seat and seatbelt. The sensors
are designed to detect the presence of a
properly seated occupant and determine
if the front passenger frontal airbag should
be enabled.
•
When the front passenger sensing
system enables the front passenger
frontal airbag (may inflate), the
passenger airbag status indicator
illuminates the on lamp and remains
illuminated.
If a person of adult size is sitting in the front
passenger seat, but the passenger airbag
status indicator off lamp is lit, it is possible
that the person is not sitting properly in the
seat. If this happens:
• Switch your vehicle off and ask the
person to place the seat backrest in an
upright position.
• Have the person sit upright in the seat,
centered on the seat cushion, with the
person's legs comfortably extended.
• Restart your vehicle and have the
person remain in this position for about
two minutes. This allows the system
to detect that person and enable the
passenger frontal airbag.
• If the indicator off lamp remains lit
even after this, you should advise the
person to ride in the rear seat.
After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit
properly. A properly seated occupant sits
upright, leaning against the seat backrest,
and centered on the seat cushion, with
their feet comfortably extended on the
floor. Sitting improperly can increase the
54
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Supplementary Restraints System

chance of injury in a crash event. For
example, if an occupant slouches, lies
down, turns sideways, sits forward, leans
forward or sideways, or puts one or both
feet up, the chance of injury during a crash
greatly increases.
If you think that the state of the passenger
airbag status indicator lamp is incorrect,
check for the following:
•
Objects lodged underneath the seat.
• Objects between the seat cushion and
the center console.
• Objects hanging off the seat backrest.
• Objects stowed in the seat backrest
map pocket.
• Objects placed on the occupant's lap.
• Cargo interference with the seat
• Other passengers pushing or pulling on
the seat.
• Rear passenger feet and knees resting
or pushing on the seat.
The conditions listed above may cause the
weight of a properly seated occupant to
be incorrectly interpreted by the front
passenger sensing system. The person in
the front passenger seat may appear
heavier or lighter due to the conditions
described in the previous list. Make sure the front passenger
sensing system is operating
properly. See Crash Sensors
and Airbag Indicator (page 58).
If the airbag readiness light is lit, do the
following:
The driver and adult passengers should
check for objects lodged underneath the
front passenger seat or cargo interfering
with the seat. If objects are lodged or cargo is interfering
with the seat, take the following steps to
remove the obstruction:
•
Pull your vehicle over.
• Switch your vehicle off.
• Driver or adult passengers should
check for any objects lodged
underneath the front passenger seat
or cargo interfering with the seat.
• Remove the obstruction(s) (if found).
• Restart your vehicle.
• Wait at least two minutes and verify
that the airbag readiness light in the
instrument cluster is no longer
illuminated.
• If the airbag readiness light in the
instrument cluster remains illuminated,
this may or may not be a problem due
to the front passenger sensing system.
Do not attempt to repair or service the
system. Take your vehicle immediately to
an authorized dealer.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact your
Customer Relationship Center.
SIDE AIRBAGS WARNING: Do not place objects
or mount equipment on or near the
airbag cover, on the side of the front or
rear seatbacks, or in areas that may
come into contact with a deploying
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash.

WARNING: Do not use accessory
seat covers. The use of accessory seat
covers may prevent the deployment of
the side airbags and increase the risk of
injury in an accident. WARNING:
Do not lean your head
on the door. The side airbag could injure
you as it deploys from the side of the
seatback. 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. 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 side airbags are on the outermost side
of the seat backrests of the front seats. In
certain sideways crashes or rollovers, the
airbags will be inflated. The airbag was
designed to inflate between the door panel
and occupant to further enhance the
protection provided occupants in side
impact crashes. The system consists of the following:
•
A label or embossed side panel
indicating that side airbags are fitted
to your vehicle.
• Side airbags inside the driver and front
passenger seat backrests.
• Front passenger sensing system.
• Crash sensors and monitoring system
with readiness indicator. See
Crash
Sensors and Airbag Indicator (page
58
).
Note: The passenger sensing system will
deactivate the passenger seat-mounted
side airbag if it detects an empty passenger
seat.
The design and development of the side
airbag system included recommended
testing procedures that were developed
by a group of automotive safety experts
known as the Side Airbag Technical
Working Group. These recommended
testing procedures help reduce the risk of
injuries related to the deployment of side
airbags.
