•
Electronic stability control and traction
control maintains your vehicle control
in adverse conditions or
high-performance driving.
• Electronic throttle control enhances
the powertrain response to your inputs.
• Transmission controls are optimized
with shift schedules tuned to each
terrain.
Using the System
The system tailors your vehicle
configuration for each mode you select.
Column Shifter To change the drive mode setting, press
the drive mode button. The drive mode
selection menu appears in the instrument
cluster and allows you to select through
the available drive modes.
Normal – For everyday driving.
This mode is a perfect balance
of excitement, comfort, and
convenience. WARNING: Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. Tow/Haul – For improved
transmission operation when
towing a trailer or a heavy load.
This mode moves upshifts to higher engine
speeds to reduce the frequency of
transmission shifting. This mode also
provides engine braking in all forward
gears, which slows your vehicle and assists
you in controlling your vehicle when
descending a grade. The amount of
downshift braking provided varies based
on the amount you press the brake pedal. Deep Snow/Sand – For snow or
soft, dry sand.
Eco – For efficient driving. This
mode helps deliver maximum
fuel efficiency and helps to
increase driving range. Slippery – For less than ideal
road conditions such as snow or
ice covered roads. Use this mode
for crossing terrain where loose, wet or
slippery material covers a firm surface.
Slippery mode lowers throttle response
and, if equipped with automatic
transmission, optimizes shifting for slippery
surfaces. Rock Crawl – For optimum
rock-climbing ability. Rock crawl
mode prompts you to put your
vehicle in 4x4 Low. Rock Crawl mode
optimizes the throttle and transmission
response to provide you additional control
of your vehicle. See
Using Four-Wheel
Drive (page 213). Some drive modes reduce
traction and stability control
performance and the warning
indicator illuminates in the instrument
cluster.

WHAT IS THE GROSS
COMBINED WEIGHT RATING
Gross Combined Weight Rating
(GCWR) is the maximum
allowable weight of the vehicle
and the loaded trailer, including
all cargo and passengers, that the
vehicle can handle without risking
damage. (Important: The towing
vehicle
’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
Note:
For trailer towing

TOWING A TRAILER
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the lowest rating capacity for
your vehicle or trailer hitch.
Overloading your vehicle or
trailer hitch can impair your
vehicle stability and handling.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death. WARNING:
Do not cut,
drill, weld or modify the trailer
hitch. Modifying the trailer hitch
could reduce the hitch rating.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuse
Specification Chart (page 339). Your vehicle may have ability to
modify trailer towing features.
See
General Information (page
110).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation.
Note: To prevent your trailer from
accumulating distance, and the
trailer information status appearing
when you restart your vehicle after
disconnecting your trailer, you must
deactivate your trailer. Using the
information display, go to the
Towing menu and then the Select
Trailer option. Select the No active
trailer option. See
General
Information (page 110).
Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
• Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the
left-hand and right-hand side
trailer tires.
282
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Towing

•
Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight. Do not
exceed the tongue load rating
indicated on the conventional
hitch receiver.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is in
another chapter of this manual.

Weights (page 300).

TRAILER REVERSING AIDS
(IF
EQUIPPED)
Pro Trailer Backup Assist With
Trailer Reverse Guidance 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 primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving.
WARNING:
This system is an extra
driving aid. It does not replace your
attention and judgment, or the need to
apply the brakes. This system does NOT
automatically brake your vehicle. If you
fail to press the brake pedal when
necessary, you may collide with another
vehicle.
283
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Towing

This feature helps you to steer your vehicle
when reversing with a trailer by:
•
Using the control knob with Pro Trailer
Backup Assist.
• Using the steering wheel with Trailer
Reverse Guidance.
Each trailer you use with your vehicle has
to be setup once.
You must take care to follow the setup
process accurately to correctly place the
sticker or sensor.
Contact your dealership if you need
assistance setting up your trailer.
Note: Your vehicle saves the trailer
information when you enter it into the
system. You can add a maximum of 10
trailers to the system.
Note: The system is not a substitute for
safe driving practices.
Note: You must always be aware of your
vehicle and trailer combination, and the
surrounding environment.
Note: The system does not detect or
prevent your vehicle or trailer from making
contact with obstacles in the surrounding
environment.
Note: Keep in mind that the front end of
your vehicle swings out when changing the
direction of the trailer. Note:
The system relies on user
measurements to determine sticker
placement or user installation of a sensor
to determine system limits. It is critical to
correctly take the key measurements or
properly install the sensor. Incorrect
measurements or sensor placement can
result in the improper function of the system
up to and including contact between your
vehicle and trailer. Even with correct
measurements and sensor placement, the
system cannot determine if the trailer body
may contact your vehicle. Check the
clearance between your vehicle and trailer,
especially for sharp turns.
Note: The system limits vehicle speed when
backing up. The system is not a replacement
for proper use of the throttle and brake
pedals.
Note: The system does not support backing
up when towing multiple trailers. If you are
towing more than one trailer, you must
disconnect the additional trailers before
using the system.
Positioning Your Vehicle and
Trailer
Hitch your trailer to your vehicle and
connect the electrical wiring harness.
Check to make sure that the wiring is
working. See Essential Towing Checks
(page 305). Park your vehicle and hitched trailer on a
level surface.
284
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- TowingE209759

For best results, make sure that your trailer
rides level with the ground when you hitch
your vehicle. More information on selecting
your towbar is available in the Towing
section. See Towing (page 282).
Make sure that the trailer and your vehicle
are in line with each other. You can do this
by putting the transmission in drive (D) and
pulling straight forward.
Setting Up the System 1. Press the button to switch the system
on.
2. Use the controls on the steering wheel
to select the option to add a trailer in
the information display. See General
Information (page 110).
3. Add a personalized name for the trailer
using the screen prompts. Use the
down arrow to scroll to the preferred
letter and then press the right arrow to
advance to the next letter. Press OK to
continue.
4. Select the Trailer Brake Type.
Note: Select Default Electric/Surge/None
if your trailer has electric, surge or no brakes.
5. Select the Trailer Brake Effort.
Note: The default option is Low. We
recommend this for most trailers. If the
trailer brakes require more initial voltage, or
if you prefer more aggressive braking, select
Medium or High.
6. Select the trailer type.
Note: The system may prompt you to setup
Trailer Blind Spot before continuing the
setup process.
7. Select whether you want to add Pro Trailer Backup Assist.
Conventional Trailer Setup
(If
Equipped)
The following are examples of
conventional trailers.
285
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- TowingE209760 E318266

Turn and hold counterclockwise to make
the trailer go left.
Turn and hold clockwise to make the trailer
go right.
Note:
Practice maneuvering with the
system in a safe open area first.
Note: Try backing up in a straight line and
then turning the knob slowly in the direction
you want to go.
Note: Quickly turning and releasing the
knob results in a jerky movement of the
vehicle. Release the knob when the trailer is
moving in the direction you want. Control
the accelerator and brakes while the
system steers your vehicle automatically
to keep the trailer moving straight back.
Note:
For fifth wheel and gooseneck
trailers, the weight and hitch position of
these trailers may make the trailer respond
differently to the knob input than
conventional trailers. You may need to
release the knob early or stop and pull
forward to align your truck and trailer when
returning to straight backing after making a
turn.
Note: Trailer maneuvering performance
may be compromised when using a fifth
wheel sliding hitch or pivoting pin box since
the system does not know the pivot point.
Note: You may have to use the knob to
correct the trailer direction when attempting
to move the trailer straight back under some
conditions.
Note: The system limits the vehicle speed.
Note: When you release the knob or turn it
to the center position, your vehicle follows
the trailer's path.
Using Trailer Reverse Guidance
This provides information graphics and up
to seven camera views to help you backup
your trailer when you use the steering
wheel. If you do not set up the system, you
can still use the camera views.
Note: The hitch angle graphic, automatic
view switching and straight backup mode
are not available if you do not set up the
system.
1. Shift into reverse (R). Press the rear camera button to expand the menu.
2. Press the trailer icon.
3. Select the applicable trailer in the information display.

•
The trailer is not detected. Once your
vehicle is stopped, additional warnings
indicate the trailer is not detected.
Refer to trailer not detected
troubleshooting tips.
• An internal condition for system
operation was not met which requires
your vehicle to return to manual control
of the steering. Using the system for an
extended period of time can cause the
steering system to heat up and turn off
Pro Trailer Backup Assist steering
control to protect itself. The system
may require a cool down time of up to
30 minutes. Keep the system off and
drive forward at a normal speed or
switch the vehicle off.
TRAILER SWAY CONTROL WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed. This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE
SPEED appears in the information display.
The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See
Load
Carrying (page 271).
RECOMMENDED TOWING
