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

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

Transport Canada Deactivation Criteria
(Canada Only)
WARNING: This vehicle has special
energy management seatbelts for the
driver and right front passenger. These
particular seatbelts are specifically
designed to work with airbags to help
reduce the risk of injury in a crash. The
energy management seatbelt gives or
releases additional seatbelt webbing in
some accidents to reduce the
concentration of force on an occupant's
chest and to reduce the risk of certain
bone fractures and injuries to underlying
organs. In a crash, if the airbag is off, this
energy management seatbelt might
permit the passenger wearing the
seatbelt to move forward enough to
have a serious or fatal injury. The more
severe the crash, and the heavier the
occupant, the greater the risk. Make sure
the airbag is on for any passenger who
does not qualify under the Transport
Canada deactivation criteria.
1. Infant: An infant (less than 1 year old)
must ride in the front seat because:
• My vehicle has no rear seat;
• The rear seat in my vehicle cannot
accommodate a rear-facing infant
seat;
• The infant has a medical condition
which, according to the infant's
physician, makes it necessary for the
infant to ride in the front seat so that
the driver can monitor the infant's
condition.
2. Child age 12 or under: A child age 12 or
under must ride in the front seat because: •
My vehicle has no rear seat;
• Although children age 12 and under ride
in the rear seat whenever possible,
children age 12 and under have no
option but to sometimes ride in the
front seat because rear seat space is
insufficient;
• The child has a medical condition that,
according to the child's physician,
makes it necessary for the child to ride
in the front seat so that the driver can
monitor the child's condition.
3. Medical condition:
A passenger has a
medical condition that, according to his or
her physician:
• Poses a special risk for the passenger
if the airbag deploys; and
• Makes the potential harm from the
passenger airbag deployment greater
than the potential harm from turning
off the airbag and experiencing a crash
without the protection offered by the
airbag
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.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Supplementary Restraints System

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.

WHAT IS AUTOMATIC HIGH
BEAM CONTROL
The system turns on high beams if it is dark
enough and no other traffic is present. If it
detects an approaching vehicle
’s
headlamps or tail lamps, or street lighting
ahead, the system turns the high beams
off. Low beams remain on.
A camera sensor, centrally mounted
behind the windshield of your vehicle,
continuously monitors conditions to turn
the high beams on and off.
SWITCHING AUTOMATIC HIGH
BEAM CONTROL ON AND OFF
Switch the system on or off using the
information display. See General
Information (page 110).
Activating the Automatic High
Beam Control Switch the lighting control to the
autolamps position to activate.
See
Autolamps (page 88).
Note: Automatic high beams are not
available when autolamps are not turned
on.
When active, the high beams turn on if:
• The ambient light level is low enough.
• There is no traffic in front of your
vehicle.
• The vehicle speed is greater than
approximately
32 mph (52 km/h).
When active, the high beams turn off if:
• The ambient light level is high enough
that high beams are not required.
• The system detects an approaching
vehicle's headlamps or tail lamps.
• The system detects severe rain, snow
or fog. •
The camera is blocked.
• The vehicle speed falls below
approximately
27 mph (44 km/h).
Note: The deactivation speed is lower on
curves.
Note: High beam reactivation may be
delayed in certain curvy road situations.

if the sensor is blocked. Keep the windshield
free from obstruction or damage.
Note: The system may not operate properly
in cold or inclement conditions. You can
switch on the high beams by overriding the
system.
Note: If the system detects a blockage, for
example bird droppings, bug splatter, snow
or ice, the system goes into low beam mode
until you clear the blockage. A message may
appear in the information display if the
camera is blocked.
Note: Using much larger tires or equipping
vehicle accessories such as snowplows can
modify your vehicle's ride height and
degrade automatic high beam control
performance.
