2021 FORD F-150 Owners Manual

•
When the front passenger sensing
system disables the front passenger
frontal airbag, the passenger airbag
status indicator illuminates the off
lamp.
• If you have installed the child restraint
and the passenger airbag status
indicator illuminates the on lamp,
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, the passenger airbag
status indicator illuminates the on
lamp.
If a person of adult size is sitting in the front
passenger seat, but the passenger airbag
status indicator off lamp is illuminated, 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
illuminated 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 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 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 listed conditions could 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 could appear
heavier or lighter due to the conditions
listed. Make sure the front passenger
sensing system is operating
properly. See Crash Sensors
and Airbag Indicator (page 79).
If the airbag readiness light is on, do the
following:
77
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing AirbagsE67017

•
Pull your vehicle over.
• Switch your vehicle off.
• Check for any objects lodged
underneath the front passenger seat
or cargo interfering with the seat.
• Remove the obstruction 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,
there may be a problem due to the
front passenger sensing system.
Do not attempt to repair or service the
system. Take your vehicle in for service
immediately.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact your
Customer Relationship Center. See
Contacting Us (page 22). FRONT PASSENGER SENSING
SYSTEM PRECAUTIONS 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.

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or adding
equipment to the front of your vehicle
could affect the performance of the
airbag system, increasing the risk of
injury. This includes the hood, bumper
system, frame, front body structure, tow
hooks, hood pins, push bar and
snowplows.
Your vehicle has a collection of crash and
occupant sensors. These sensors provide
information to the restraints control
module which activates the following:
• Front seatbelt pretensioners.
• Driver airbag.
• Passenger airbag.
• Knee airbag(s).
• Seat mounted side airbags.
• Safety Canopy.
Based on the type of crash, the restraints
control module deploys the appropriate
safety devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following: The readiness light will not
illuminate immediately after you
switch the ignition on. •
The readiness light either flashes or
stays on.
• You hear a series of five tones. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced immediately.
Unless serviced, the system may not
function properly in the event of a crash.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, seatbelt usage)
were not appropriate to activate these
safety devices.
• The front airbags activate only in
frontal and near-frontal crashes. Front
airbags may activate in rollovers, side
impacts or rear impacts if the crash
causes sufficient frontal deceleration.
• The seatbelt pretensioners activate in
frontal, near-frontal and side crashes,
and in rollovers.
• The knee airbag(s) deploy based on
crash severity and occupant conditions.
• The side airbags inflate in certain side
impact crashes or rollover events. Side
airbags may activate in other types of
crashes if the vehicle experiences
sufficient sideways motion or
deformation.
• The Safety Canopy inflates in certain
side impact crashes or rollover events.
The Safety Canopy may activate in
other types of crashes if the vehicle
experiences sufficient sideways motion
or deformation, or a certain likelihood
of rollover.

Airbags and Police Equipment 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:
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.
Dual driver and passenger airbags, side
airbags and knee airbags affect the way
police equipment can be mounted in police
vehicles.
Any surfaces that could come into contact
with an airbag, once it has deployed, must
not damage the airbag or alter its
deployment path. Once the airbag has fully deployed, any
peripheral equipment surfaces that could
come into contact with the airbag, such as
when the airbag deflates with the loading
of an occupant, must not damage the
airbag or alter its deployment path. Sharp
edges, corners or protrusions could
damage the nylon airbag material and
reduce the effectiveness of the airbag.
Some approximate dimensions for airbags,
at full inflation, are provided. These
dimensions are somewhat flexible and
represent free form deployments without
the loading of occupants. The shaded
areas in Figures 8 through 10 represent
available police equipment mounting
zones. These zones are shown for police
vehicles with standard bucket seats. The
zone dimensions provided in Figures 8
through 10 are approximate and will vary
with the loading of occupants in the seats.
All airbag and equipment mounting zone
dimensions are approximate due to
different airbag deployment
characteristics.
Do not mount equipment between the side
of the front seat and the door trim that will
block deployment of the side airbag.
Do not mount equipment between the
seats and the body side as shown in Figure
7 that would prevent the side curtain airbag
from achieving occupant coverage.
