REPLACEMENT PARTS
RECOMMENDATION
We have built your vehicle to the highest
standards using quality parts. We
recommend that you demand the use of
genuine Ford and Motorcraft parts
whenever your vehicle requires scheduled
maintenance or repair. You can clearly
identify genuine Ford and Motorcraft parts
by looking for the Ford, FoMoCo or
Motorcraft branding on the parts or their
packaging.
Scheduled Maintenance and
Mechanical Repairs
One of the best ways for you to make sure
that your vehicle provides years of service
is to have it maintained in line with our
recommendations using parts that
conform to the specifications detailed in
this Owner
’s Manual.
Genuine Ford and Motorcraft parts meet
or exceed these specifications.
Collision Repairs
We hope that you never experience a
collision, but accidents happen sometimes.
Genuine Ford replacement collision parts
meet our stringent requirements for fit,
finish, structural integrity, corrosion
protection and dent resistance. During
vehicle development we validate that
these parts deliver the intended level of
protection as a whole system. A great way
to know for sure you are getting this level
of protection is to use genuine Ford
replacement collision parts.
Warranty on Replacement Parts
Genuine Ford and Motorcraft replacement
parts are the only replacement parts that
benefit from a Ford Warranty. The Ford Warranty may not cover damage
caused to your vehicle as a result of failed
non-Ford parts.
For additional information, refer to the
terms and conditions of the Ford Warranty.
SPECIAL NOTICES
New Vehicle Limited Warranty
For a detailed description of what is
covered by your New Vehicle Limited
Warranty, see your warranty guide that is
available online. For more information,
refer to our website and download your
copy of the warranty guide
Special Instructions
For your added safety, your vehicle has
sophisticated electronic controls.
WARNING: You risk death or
serious injury to yourself and others if you
do not follow the instruction highlighted
by the warning symbol. Failure to follow
the specific warnings and instructions
could result in personal injury. WARNING: Never
place front seat
mounted rear-facing child or infant seats
in front of an active passenger airbag.
On Board Diagnostics Data Link
Connector WARNING:
Do not connect
wireless plug-in devices to the data link
connector. Unauthorized third parties
could gain access to vehicle data and
impair the performance of safety related
systems. Only allow repair facilities that
follow our service and repair instructions
to connect their equipment to the data
link connector.
16
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Introduction

Your vehicle has an OBD Data Link
Connector (DLC) that is used in
conjunction with a diagnostic scan tool for
vehicle diagnostics, repairs and
reprogramming services. Installing an
aftermarket device that uses the DLC
during normal driving for purposes such as
remote insurance company monitoring,
transmission of vehicle data to other
devices or entities, or altering the
performance of the vehicle, may cause
interference with or even damage to
vehicle systems. We do not recommend
or endorse the use of aftermarket plug-in
devices unless approved by Ford. The
vehicle Warranty will not cover damage
caused by an aftermarket plug-in device.
Using your Vehicle With a
Snowplow
More information and guidelines for using
your vehicle with a snowplow are in this
Owner's Manual. See Snow Plowing
(page 321).
Using a Slide-In Camper
For information regarding the use of
slide-in campers, consult the Truck
Camper Loading document supplied with
your vehicle.
Using your Vehicle as an
Ambulance
If your light truck has the Ford Ambulance
Preparation Package, it may be utilized as
an ambulance. We urge ambulance
manufacturers to follow the
recommendations of the Ford Incomplete
Vehicle Manual, Ford Truck Body Builder ’s
Layout Book and the Qualified Vehicle
Modifiers (QVM) Guidelines as well as pertinent supplements. For additional
information, please contact the Truck Body
Builders Advisory Service at
http://www.fleet.ford.com/truckbbas/
and then by selecting Contact Us or by
phone at 1–877
–840–4338.
Use of your Ford light truck as an
ambulance, without the Ford Ambulance
Preparation Package voids the Ford New
Vehicle Limited Warranty and may void
the emissions warranties. In addition,
ambulance usage without the preparation
package could cause high underbody
temperatures, overpressurized fuel and a
risk of spraying fuel which could lead to
fires.
If your vehicle has the Ford Ambulance
Preparation Package, it will be indicated
on the Safety Compliance Certification
Label. The label is on the driver side door
pillar or on the rear edge of the driver door.
You can determine whether the
ambulance manufacturer followed Ford ’s
recommendations by directly contacting
that manufacturer. The Ford Ambulance
Preparation Package is only available on
certain diesel engine equipped vehicles.
Using your Vehicle as a Stationary
Power Source
Information and guidelines for operating a
vehicle with an aftermarket power take-off
system are in this Owner's Manual.
See
Power Take-Off (page 212).
MOBILE COMMUNICATIONS
EQUIPMENT WARNING:
Driving while
distracted can result in loss of vehicle
control, crash and injury. We strongly
recommend that you use extreme
caution when using any device that may
take your focus off the road. Your
17
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Introduction

Note:
The automatic locking mode is
available on the front passenger and rear
seats. This vehicle does not require the use
of a locking clip.
6. Allow the belt to retract to remove slack. The belt clicks as it retracts to
indicate it is in the automatic locking
mode.
7. Try to pull the belt out of the retractor to make sure the retractor is in the
automatic locking mode. You should
not be able to pull more belt out. If the
retractor did not lock, unbuckle the belt
and repeat Steps 5 and 6. 8.
Remove remaining slack from the belt.
Force the seat down with extra weight,
for example, by pressing down or
kneeling on the child restraint while
pulling up on the shoulder belt in order
to force slack from the belt. This is
necessary to remove the remaining
slack that exists once you add the extra
weight of the child to the child restraint.
It also helps to achieve the proper
snugness of the child restraint to your
vehicle. Sometimes, a slight lean
toward the buckle helps to remove
remaining slack from the belt.
9. If the child restraint has a tether strap, attach it. 10. Before placing the child in the seat,
forcibly move the seat forward and
back to make sure the seat is securely
held in place.
To check this, grab the seat at the belt path
and attempt to move it side to side and
forward and back. There should be no
more than 1 in (2.5 cm) of movement for
proper installation.
We recommend checking with a NHTSA
Certified Child Passenger Safety
Technician to make certain the child
restraint is properly installed. In Canada,
check with Transport Canada for referral
to a Child Car Seat Clinic.
Using Lap and Shoulder Belts
(Front Center Position of Super
Cab and Crew Cab) 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:
Always use both the
lap and shoulder portion of the seatbelt
in the center seating position.

PRINCIPLE OF OPERATION
WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips. WARNING:
Children must always
be properly restrained. WARNING:
Do not allow a
passenger to hold a child on their lap
when your vehicle is moving. Failure to
follow this instruction could result in
personal injury or death in the event of a
sudden stop or crash. 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:
It is extremely
dangerous to ride in a cargo area, inside
or outside of a vehicle. In a crash, people
riding in these areas are more likely to be
seriously injured or killed. Do not allow
people to ride in any area of your vehicle
that is not equipped with seats and
seatbelts. Make sure everyone in your
vehicle is in a seat and properly using a
seatbelt. Failure to follow this warning
could result in serious personal injury or
death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Each seating position
in your vehicle has a specific seatbelt
assembly made up of one buckle and
one tongue designed to be used as a pair.
Use the shoulder belt on the outside
shoulder only. Never wear the shoulder
belt under the arm. Never use a single
seatbelt for more than one person. 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:
Seatbelts and seats
may be hot in a vehicle that is in the
sunshine. The hot seatbelts or seats may
burn a small child. Check seat covers and
buckles before you place a child
anywhere near them.
All seating positions in this vehicle have
lap and shoulder belts. All occupants of
the vehicle should always properly wear
their seatbelts, even when an airbag
supplemental restraint system is provided.
The seatbelt system consists of:
• Lap and shoulder seatbelts.
• Shoulder seatbelts with automatic
locking mode, (except the driver
seatbelt).
• Height adjusters at the front outermost
seating positions.
• Seatbelt pretensioners at the front
outermost and rear outermost seating
positions. •
Seatbelt warning light and chime.

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 391). 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.
If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
our dealers. Only use our seatbelt
extensions made by the original equipment
seatbelt manufacturer with our seatbelts.
Ask your authorized dealer if your extension
is compatible with your vehicle restraint
system.
