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,

serviced immediately by a qualified
technician. WARNING:
To avoid switching on
the airbag, always remove the ignition
key with the switch in the off position. WARNING:
If your vehicle has rear
seats, always transport children who are
12 and younger in the rear seat. Always
use seatbelts and child restraints
properly. Do not place a child in a rear
facing infant seat in the front seat unless
your vehicle is equipped with an airbag
on and off switch and the passenger
airbag is turned off. This is because the
back of the infant seat is too close to the
inflating airbag and the risk of a fatal
injury to the infant when the airbag
inflates is substantial.
The passenger airbag on and off switch is
in the glovebox. 1. Insert the ignition key, turn the switch
to OFF and hold in OFF while removing
the key.
2. When you switch the ignition on, the passenger airbag off light illuminates
briefly, momentarily shuts off and then
switches back on. This indicates that
the passenger airbag is deactivated.
Switching the Passenger Airbag Back
On WARNING:
The seatbelts for the
driver and right front passenger seating
positions are specifically designed to
operate together with the airbags in
certain types of crashes. When you
switch off your airbag, you not only lose

the protection of the airbag, you also
may reduce the effectiveness of your
seatbelt system. If the passenger does
not meet the requirements stated in the
National Highway Traffic Safety
Administration or Transport Canada
deactivation criteria, switching off the
airbag can increase the risk of serious
injury or death in a crash.
WARNING: If your vehicle has rear
seats, always transport children who are
12 and younger in the rear seat. Always
use seatbelts and child restraints
properly. Do not place a child in a rear
facing infant seat in the front seat unless
your vehicle is equipped with an airbag
on and off switch and the passenger
airbag is turned off. This is because the
back of the infant seat is too close to the
inflating airbag and the risk of a fatal
injury to the infant when the airbag
inflates is substantial. WARNING:
If the passenger airbag
off light is illuminated when the
passenger airbag switch is on and the
ignition is on, have the passenger airbag
switch serviced immediately by a
qualified technician.
The passenger airbag remains off until you
switch it back on. 1. Insert the ignition key and turn the
switch to ON.
2. The passenger airbag off light will briefly illuminate when you switch the
ignition on. This indicates that the
passenger airbag is operational.
The passenger side airbag should always
be on (the passenger airbag off light
should not be illuminated) unless the
passenger is a person who meets the
requirements stated either in Category 1, 2
or 3 of the National Highway Traffic Safety
Administration or Transport Canada
deactivation criteria which follows.
The vast majority of drivers and passengers
are much safer with an airbag than
without. To do their job and reduce the risk
of life threatening injuries, airbags must
open with great force, and this force can
pose a potentially deadly risk in some
situations, particularly when a front seat
occupant is not properly buckled up. The
most effective way to reduce the risk of
unnecessary airbag injuries without
reducing the overall safety of the vehicle
is to make sure all occupants are properly
restrained in the vehicle, especially in the
front seat. This provides the protection of
seatbelts and permits the airbags to
provide the additional protection they were
46
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Supplementary Restraints SystemE181521

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 back, 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 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.
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:
Accessory seat covers
not released by Ford Motor Company
could prevent the deployment of the
airbags and increase the risk of injuries
in a crash. 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.

Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Supplementary Restraints SystemE142846

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 front seat backrests. In certain
sideways crashes or rollover events, the
side airbags will be inflated. The airbag
was designed to inflate between the door
panel and occupant to further enhance the
protection provided to occupants in side
impact crashes. The system consists of the following:
•
A label or embossed side panel
indicating that your vehicle has side
airbags.
• Side airbags inside the driver and front
passenger seat backrests. Crash sensors and monitoring
system with readiness indicator.
See Crash Sensors and Airbag
Indicator
(page 51). 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.
SAFETY CANOPY™
WARNING:
Do not place objects
or mount equipment on or near the
headliner at the siderail that may come
into contact with a deploying curtain
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING:
Do not lean your head
on the door. The curtain airbag could
injure you as it deploys from the
headliner. 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:
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:
To reduce risk of injury,
do not obstruct or place objects in the
deployment path of the airbag.

Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Supplementary Restraints SystemE152533 E67017

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 lit.
• You hear a series of five beeps. 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 at an authorized
dealer 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, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts unless the crash causes
sufficient frontal deceleration).
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal and side crashes, and in
rollovers. •
The design of the side airbags is to
inflate in certain side impact crashes.
Side airbags may activate in other
types of crashes if the vehicle
experiences sufficient sideways motion
or deformation.
• The design of the Safety Canopy is to
inflate 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.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.
