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.
See Recommended Towing
Weights (page 300).

A small representation shows you two
zones to warn you of a possible jackknife
condition. The view shows your truck and
trailer position and provides visual
feedback to help avoid a jackknife
condition entirely.
The yellow zone indicates you are
approaching the maximum controllable
trailer angle for the system. When your
trailer enters this zone, it is more difficult
to reduce the trailer turn when backing up.
It may be necessary to put your vehicle
back into drive (D) and pull forward to get
the truck and trailer back to an in-line
position.
The red zone indicates you have exceeded
the maximum controllable trailer angle for
the system. Put the truck into drive (D) and
pull forward until your trailer is no longer
in the red zone.
Troubleshooting - Conventional
Trailer
Note:
The system requires a clear view of
the sticker placed on the trailer. You must
keep the camera lens and sticker clean for
the system to operate correctly.
Setup
The system is designed to be used with a
wide variety of trailers. There are some
trailers that do not have a proper surface
and location to mount the sticker. These
trailers are not supported. Attempts to
place the sticker on a surface that does
not meet the sticker placement
requirement listed in Step 3 of the setup
instruction or entering inaccurate
measurements to proceed through setup
can result in improper system function. Accurate measurements are critical for
correct system function. If you need to
check measurements entered or change
them, you can access them through the
instrument cluster. Choose the option to
change the sticker from the change trailer
settings menu. It is not necessary to
remove the sticker if you are just reviewing
or changing measurements.
The following menu warnings or difficulties
may occur during setup. Tips to resolve
them are listed below.
Note:
If you still experience issues with the
system's ability to detect the sticker, see
the information in the next section regarding
sticker lost during system operation.
Measurement A has reached maximum or
minimum value:
• The system is designed to work with
drawbars that have a license plate to
hitch ball center measurement of
9–20 in (23–52 cm) when installed.
Do not attempt to use drawbars that
have a length outside this range as the
system performance degrades and
could cause improper system function.
• Make sure that the measurement being
made is the horizontal distance only
from license plate to the hitch ball
center. A straight line distance that
includes any vertical rise or drop
increases the measurement and makes
it inaccurate. Inaccurate
measurements degrade system
performance and could cause improper
system function. See step 4 of the
setup instruction to review
measurement instructions.
292
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Towing

Measurement B has reached maximum or
minimum value:
•
Make sure that the sticker placement
instruction in step 3 of the setup has
been followed. Stickers placed outside
the allowed zone adversely affects the
system performance and could cause
improper feature function.
• Make sure that the measurement being
made is the horizontal distance only
from center of sticker to the hitch ball
center. A straight line distance that
includes any vertical rise or drop
increases the measurement and
causes an inaccurate value to be
entered into the system. See step 4 of
the setup for additional measurement
instructions.
Measurement C has reached maximum or
minimum value:
• Make sure you follow the sticker
placement instructions in step 3 of the
setup. Stickers placed outside the
allowed zone adversely affect the
system performance and could cause
improper feature function. If you have
met all the criteria for sticker
placement and you see this message,
the sticker is either too far below or too
close to the camera to properly
recognize the sticker. For the system
to operate correctly, the sticker height
must be lowered if you receive the
minimum warning or the sticker height
must be raised if you receive the
maximum warning.
• Only one sticker can be placed on the
trailer for correct system function. The
previous sticker must be removed or
covered so only one sticker is visible to
the camera.
• Measurement B and C must be
measured again if a new sticker is
placed on the trailer. Measurement D has reached maximum or
minimum value:
•
Make sure that the measurement being
made is the horizontal distance only
from tailgate to the center of the single
axle or the center of all the axles on the
trailer. See step 4 of the setup for
additional measurement instructions.
The system does not support trailer
lengths outside the range allowed by
the information display.
System is circling something beside the
sticker or system cannot find the sticker:
• Make sure the rear camera is clean and
the sticker is clearly visible in the
camera image. Clean the camera and
sticker if necessary.
• The camera system uses the entered
measurements to help locate the
sticker. Inaccurate sticker
measurements degrade the system ’s
ability to locate the sticker. Verify the
measurements you enter into the
system are accurate.
• Remove the incorrectly circled label or
decal if possible.
• If you cannot resolve the issue, try a
new sticker location. The sticker
location must still meet the
requirements noted in step 3 of the
setup instructions. Only one sticker can
be placed on the trailer for correct
system function. The previous sticker
must be removed or covered so only
one sticker is visible to the camera.
Calibration
The system monitors various vehicle
parameters to ensure your vehicle is being
driven straight and the trailer is straight
behind your vehicle. Any steering input or
trailer movement pauses the calibration.
293
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Towing

For best results:
•
Use a long, straight, smooth and level
road when attempting to calibrate.
• Drive straight forward.
• Drive between 4–24 mph
(6– 39 km/h).
System Operation
The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below.
Pro Trailer Backup Assist™ System is Not

• Check for the following if you receive
the lost sticker message while using
the system.
• Stop your vehicle as soon as the
message displays.
• Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.
• Clean the sticker and camera to make
sure they are unobstructed.
• Clean the lens with a soft, lint-free
cloth and water.
• Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the
sticker, and then wipe clean with a soft
cloth.
• Remove any items that may be
blocking the view of the sticker.
Depending on your trailer configuration
and any equipment mounted to your
trailer, it is possible for the sticker to be
blocked from view of the camera as it
rotates on the hitch ball but not be
blocked during setup. Remove the
obstruction if possible. It may be
necessary to remove the sticker from
its current location if the obstruction
cannot be cleared. Place a new sticker
that is visible to the camera in all
positions of the trailer behind your
vehicle.

four reasons why this warning displays
and additional information regarding
the reason for the warning is available
on the center display.
• The steering wheel is touched when
under system control. Avoid touching
the wheel during system operation.
• The maximum speed for feature
operation is exceeded. System
performance is optimized at slower
speeds. Reverse slowly.
• The sticker was lost by the camera
system. Once your vehicle is stopped,
additional warnings indicate the sticker
was lost. Refer to sticker lost
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.
Note: The system is designed to be used
with the same trailer connection every time
the trailer is chosen from the selection
menu. When using a different drawbar or a
different pin hole on drawbars with more
than one, connecting the drawbar to your
vehicle affects the trailer measurements.
Take the measurements again and update
if required.

Troubleshooting - Fifth Wheel and
Gooseneck Trailer
Setup
The system is designed to be used with a
wide variety of trailers. There are some
trailers that do not have a proper surface
and location to mount the sensor. These
trailers are not supported. Attempts to
install the sensor in a manner that does
not meet the requirements can result in
improper system function.
To correctly install the trailer sensor:
•
Attach to vertical surface with the
arrows pointed straight up.
• If you are not sure, use a level to check
that the attachment surface is vertical.
• Securely fasten the sensor so that it is
rigidly mounted and does not shake or
wobble.
• Install within the range of the 12 way
connector so that when the trailer
swings the wire harness does not
stretch, pinch or pull.
If the system displays Pro Trailer Backup
Assist™ Sensor Not Detected Refer to
Owner's Manual Press Knob to Exit or
Trailer Reverse Guidance Sensor Not
Detected Refer to Owner's Manual Press
OK to Exit:
• Check that the 12 way connector is fully
inserted into the 12 way socket. The red
rubber seal is not visible when the
connector is fully inserted.
• Check that the wiring harness sensor
connection is fully inserted at the trailer
sensor.
• Check for damaged wiring between the
12 way connector and the trailer sensor.
• If you have a 12 way connector inside
the bed and in the bumper, ensure that
only a single sensor is connected. Note:
If you did not purchase the fifth wheel
prep pack, you need to replace the 7/4 way
trailer connector in your bumper with a 7/12
pin connector. See your authorized dealer.
Calibration
The calibration process is required for the
system to determine the trailer length. The
system supports trailer lengths of 10– 39 ft
(3– 11.94 m) distance from the hitch point
to the center of the axle or axles. The
calibration process consists of a straight
forward drive followed by a turn. During
the straight drive, the system monitors
various vehicle parameters to make sure
your vehicle is being driven straight and the
trailer is straight behind your vehicle. Any
steering input or trailer movement during
this straight drive pauses the calibration.
During the turn, the system monitors
various vehicle parameters to make sure
your vehicle and trailer are correctly
turning.
For best results:
• Use a smooth and level road when
attempting to calibrate.
• Steer and smoothly turn and avoid
abrupt steering inputs.
• Drive between 2 –16 mph (4– 25 km/h)
.
• Make a typical 90 degree corner turn.
Turning too shallow does not allow the
system to calibrate.
The typical calibration process results in
the system displaying messages in the
information display. The system also
displays additional warnings if the vehicle
or trailer motion is not within the
calibration limits.
