LOAD CARRYING
PRECAUTIONS
Keep your loaded vehicle weight
within its design rating capability,
with or without a trailer. Properly
loading your vehicle provides
maximum return of vehicle design
performance. Before you load your
vehicle, become familiar with the
following terms for determining
your vehicle
’s weight rating, with
or without a trailer, from the
vehicle ’s Tire and Loading
Information label or Safety
Compliance Certification label. WARNING: Vehicles with
a higher center of gravity (utility
and four-wheel drive vehicles)
handle differently than vehicles
with a lower center of gravity
(passenger cars). Avoid sharp
turns, excessive speed and
abrupt steering in these vehicles.
Failure to drive cautiously
increases the risk of losing
control of your vehicle, vehicle
rollover, personal injury and
death. WARNING:
The
appropriate loading capacity of
your vehicle can be limited either
by volume capacity (how much
space is available) or by payload
capacity (how much weight the
vehicle should carry). Once you
have reached the maximum payload of your vehicle, do not
add more cargo, even if there is
space available. Overloading or
improperly loading your vehicle
can contribute to loss of vehicle
control and vehicle rollover.
WARNING:
Exceeding the
Safety Compliance Certification
label vehicle weight limits can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death. WARNING:
Do not use
replacement tires with lower
load carrying capacities than the
original tires because they may
lower your vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
original tires do not increase the
GVWR and GAWR limitations. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING: Exceeding any
vehicle weight rating can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death.

When towing a trailer:
•
Obey country specific regulations for
towing a trailer.
• Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off when you are
towing on long, steep slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not continuously
apply the brakes, as they may overheat
and become less effective.
• If your transmission has Grade Assist
or Tow/Haul, use this feature when
towing. This provides engine braking
and helps eliminate excessive
transmission shifting for optimum fuel
economy and transmission cooling.
• Your vehicle has AdvanceTrac with roll
stability control. When towing a trailer,
additional loads could cause the
AdvanceTrac system to engage during
cornering maneuvers. Reduce cornering
speeds to make sure that you can
maintain control of the vehicle and
trailer if the AdvanceTrac system
engages. •
Allow more distance for stopping with
a trailer attached. Anticipate stops and
gradually brake.
• Avoid parking on a slope. However, if
you must park on a slope, turn the
steering wheel to point your vehicle
tires away from traffic flow, set the
parking brake, place the transmission
in park (P) and place wheel chocks in
front and back of the trailer wheels.
Note: Chocks are not included with your
vehicle.
LAUNCHING OR RETRIEVING
A BOAT OR PERSONAL
WATERCRAFT
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding
6 in (15 cm) could allow water
to enter vehicle components, causing
internal damage to the components and
affecting driveability, emissions and
reliability.
Note: Replace the rear axle lubricant
anytime the rear axle has been submerged
in water.
Note: Disconnect the trailer wiring
connector before backing the trailer into the
water.
Note: Reconnect the trailer wiring
connector after removing the trailer from
the water.

• Radar.
• Parking aid sensors.
• External rear lighting.
This feature also controls the following to
align the hitch ball with the trailer coupler:
• Steering.
• Shifting.
• Braking and acceleration.
Note: Blocked sensors could affect system
performance. Do not cover the sensors with
bumper stickers, tape, repair compound or
other objects.
TRAILER HITCHING
ASSISTANCE PRECAUTIONS WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING: The system is not
designed to detect cyclists,
motorcyclists, pedestrians or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result
personal injury or death. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash.
Note: Trailer hitching assistance only works

Refer to the instructions included with your
trailer sensor for detailed information
regarding installation.
Note:
Make sure the arrows on the sensor
housing are facing up. Mount the sensor to
a vertical part of the trailer that pivots when
you turn your vehicle. Do not mount to a
stationary surface such as the truck side of
the trailer hitch.
Note: If your vehicle came with a trailer
sensor kit, the vehicle will receive an update
that allows the system to operate with a
sensor or sticker. If your vehicle did not come
with a trailer sensor kit, your vehicle can be
setup using either method, but you need to
separately purchase the trailer sensor kit
from your authorized dealer. Once your
vehicle is enabled for sticker setup, the
default setup for new trailers requires
placement of the sticker. To setup a trailer
with a sensor, install the sensor on the trailer
and plug the connector into the connector
in your bumper prior to configuring the
trailer. Trailers that were set up with a
sensor still require the sensor to function.
To change a trailer to use the sticker, delete
the trailer in the system and repeat the
trailer setup with the sticker. CALIBRATING THE SYSTEM
Calibrating the system requires driving
forward and turning left or right. Follow the
instructions on the touchscreen to
complete the calibration process.
Note:
To calibrate the system, you need an
area where you can safely drive forward and
turn left or right. An open parking lot is an
ideal place to perform the calibration.
Note: Keep the steering wheel straight
when instructed to by the touchscreen. If
the steering wheel is in a turned position
during this instruction, the calibration
pauses.
Note: During calibration, the system
determines the trailer length. The system
supports trailer lengths of 6– 33 ft
(1.85– 10.05 m) distance from the hitch
point to the center of the axle or axles. The
system is designed to work with drawbars
that have a license plate to hitch ball center
measurement of 9– 18 in (23–46 cm) when
installed. Do not attempt to use drawbars
or trailers that have a length outside of this
range as the system performance degrades
and could cause improper system function.

Note:
The touchscreen shows if you are
going too slow or fast. Calibration pauses if
the speed is outside the required range of
2 –9 mph (4– 15 km/h).
Note: You need to complete at least a 90°
turn, and longer trailers could require a 180°
turn. Camera trailer tracking requires the
system to locate the hitch ball as well as
determine the trailer length. Some trailers
could require you to drive straight then turn
multiple times before calibration completes.
The touchscreen provides instructions and
notifies you when calibration completes.
Note: For best results, do not calibrate the
system at night when calibrating the system
with the sticker.
SWITCHING TRAILER BACKUP
ASSISTANCE ON AND OFF Press the button and use the touchscreen
to select the connected trailer. Note:
A trailer must be configured to use
trailer backup assistance. See Configuring
the Trailer (page 446).
Note: If you use the steering wheel when
using trailer backup assistance, the system
turns off and a message displays in the
touchscreen.
Note: If the trailer was connected just prior
to turning the system on, you may need to
drive forward to initialize the system. Follow
the instructions on the touchscreen to
activate the system.
USING THE TRAILER BACKUP
ASSISTANCE CONTROLLER
Use the control knob to steer the trailer.
Take your hands off the steering wheel and
turn the control knob instead. The control
knob acts as the steering control for the
trailer. Turn and hold counterclockwise to make
the trailer go left.

TRAILER BACKUP ASSISTANCE
– FREQUENTLY ASKED
QUESTIONS
Why does the trailer not reverse
straight?
Verify the sensor is correctly installed.
Other factors such as the hitch
connection, road camber, road slope
and trailer suspension could influence
how straight the system can reverse
the trailer when the control knob is not
turned. You can compensate for the
trailer drifting to the right or left by
slowly turning the knob until the trailer
is following your desired path and then
holding the knob in that position.
Why does the system not detect a
sensor? There could be an issue with the
connection, the wiring harness could
be damaged, you could have multiple
sensors connected or the sensor could
be incorrectly installed. 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. Also check that the
wiring harness sensor connection is
fully inserted at the trailer sensor, and
check for damaged wiring between
the 12-way connector and the trailer
sensor. Also, check that the sensor is
installed on a vertical surface with the
arrows pointing straight up. What does it mean if the system
remains on one message for an
extended time during calibration when
setting up the system with the sticker?
The camera could need to be cleaned,
the sticker could be blocked, the
drawbar could be outside the allowed
range of 4–19 in (10–48 cm) or you
could need to move to a different area
to change the lighting and background.
Verify the sticker is in the proper
location. See
Applying the Trailer
Reversing Aid Sticker (page 448).
You can move to a different area or
change the direction you are driving or
setup the system at a different time
of day. Some trailers are not
compatible with the sticker and
camera system. If the issue persists
with the sticker setup, you may choose
to setup the trailer with a sensor.
What does it mean if the system pauses
during calibration? There could be steering input or trailer
movement during the straight drive
portion of the calibration process.
What does it mean if the system
remains on one message for an
extended time during calibration when
setting up the system with the sensor? The sensor could be incorrectly
installed, the trailer length could be
outside the allowed range or the road
surface could be too rough or bumpy.
What does it mean if the system
displays hold steering steady during
turn? Part of the calibration process for the
sticker setup requires a steady turn. If
you are continually moving the
steering wheel during the turn, this
delays the calibration process. To
enable the calibration process, hold
the steering wheel at the same
position when turning.
456
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Trailer Backup Assistance

What does it mean if the system
displays that it is not available?
There could be a sub-system that the
system uses that is not correctly
operating or there could be a battery
voltage issue. If the system continues
to display it is not available, visit your
authorized dealer to have your vehicle
checked.
What does it mean if the system
displays that driving is required to
initialize steering? The steering system needs to learn
internal parameters to fully turn on the
feature. Drive your vehicle straight
forward above 25 mph (40 km/h) for
approximately 5 minutes. This could
also occur when your vehicle is new,
there is a battery voltage issue or if the
steering system has been serviced.
What does it mean if the system does
not detect a trailer when configured
with a sensor? Verify that the sensor is properly
connected. See
Trailer Sensor
Installation (page 448). Repeat
calibration on a different route if you
have verified sensor installation.
What does it mean if the system
requires you to pull forward to
initialize? This occurs when the vehicle has not
moved during the current key cycle
after you connect and select the trailer
in the touchscreen or you operate the
system at speeds below
1 mph
(1 km/h) for an extended period of
time. Drive forward above 2 mph
(3 km/h) and the system indicates
when it initializes. What does it mean if the trailer is at its
maximum angle or the system
deactivated by trailer angle?
You are at the maximum controllable
trailer angle for the system. Place your
vehicle in drive (D) and pull forward to
get the truck and trailer back to an
in-line position. If this message
consistently displays, this could
indicate the sensor is incorrectly
installed, the trailer needs to be
recalibrated or the drawbar or the
trailer dimensions are outside of the
supported range. The system is
designed to work with drawbars that
have a license plate to hitch ball center
measurement of
9–18 in (23–46 cm)
when installed. The system is designed
to work with trailers that have a hitch
point to center of the axle or axles
measurement of
6– 33 ft
(1.85– 10.05 m). Do not attempt to use
drawbars or trailers that have a length
outside of this range as the system
performance degrades and could
cause improper system function.
Check that the correct trailer is
selected in the touchscreen. Verify the
sensor is installed according to the
instructions included in the sensor kit
and check that the drawbar and the
trailer dimensions are within the
allowed range. Then, delete the trailer
from the system and repeat the setup
process to calibrate the trailer.
