Switching the Passenger Airbag Off WARNING: If the light does not
illuminate when the passenger airbag
switch is off and you switch the ignition
on, have the passenger airbag switch
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

Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Supplementary Restraints SystemE181522

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.

If you use anything other than our parts for
maintenance replacements or for service
of components affecting emission control,
such aftermarket parts should be
equivalent to our genuine parts in
performance and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are:
1. Your vehicle has run out of fuel —the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Running Out of Fuel
(page 183).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. You do not require
additional vehicle service.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.
