WHAT IS TRAILER HITCHING
ASSISTANCE
Trailer hitching assistance helps the driver
align the vehicle hitch ball to a trailer
coupler.
HOW DOES TRAILER HITCHING
ASSISTANCE WORK
Trailer hitching assistance uses the
following to detect your trailer:
•
Rear view camera.
• 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.

Positioning the Trailer
Hitch the trailer to your vehicle and
connect the electrical wiring harness.
Check to make sure that the wiring is
working. See Connecting a Trailer (page
424).
Park your vehicle and hitched trailer on a
level surface.
For best results, make sure that your trailer
rides level with the ground when you hitch
your vehicle. See
Connecting a Trailer
(page 424). 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.
Configuring the Trailer in the
Touchscreen
1. Press the button to switch the system
on.
2. Press
Add Trailer on the touchscreen.
3. Follow the directions on the touchscreen to enter the trailer name
and trailer type, then proceed to the
sticker or sensor setup.
Note: If you configure the trailer and install
a sensor, the trailer is saved with that sensor
information. If you want to use this trailer
with the sticker, you need to delete the
trailer from the system and repeat the setup
process.

Note:
Your vehicle has two options for the
trailer reversing aid setup. If your vehicle
came with a trailer sensor kit or if a message
displays to install a sensor, follow the sensor
installation instructions. See Trailer Sensor
Installation (page 448). If your vehicle did
not come with a trailer sensor kit, follow the
sticker installation instructions. See
Applying the Trailer Reversing Aid Sticker
(page
448).
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.
APPLYING THE TRAILER
REVERSING AID STICKER
Place the sticker in an area visible by the
rear view camera. The entire sticker must
be within
4– 19 in (10–48 cm) from the
center of the hitch ball, as shown in the
following illustration. Use the supplied sticker placement card,
a tape measure and pen to carefully mark
the area to attach the sticker. The sticker
is in the back cover pocket of your quick
start guide. Make sure the entire sticker is
within the green zone between the two
arcs or distance markers on the diagram,
and is also visible in the rear view camera
display.
Once you have found the correct location,
place the sticker.
Note:
Make sure nothing can obstruct the
rear view camera's view of the sticker such
as a jack handle or wiring.
Note: Position the sticker on a flat, dry and
clean horizontal surface. For best results,
apply the sticker when temperatures are
above
32°F (0°C).
Note: Do not move stickers after placing
them. Do not re-use any stickers if removed.
Note: You can purchase additional stickers
through your authorized dealer.
Note: If you previously setup the trailer with
the trailer sensor, make sure it is not plugged
in before configuring the trailer and placing
the sticker.

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.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Trailer Backup Assistance

What does it mean when the system
tells you to take control of the steering
wheel?
The system is no longer steering the
vehicle and you must take over
steering. There are four reasons the
system could display this message.
The first reason the system could
display this message is that you have
touched the steering wheel when the
system is steering. The second reason
the system could display this message
is that you have exceeded the
maximum speed for the feature. The
third reason the system could display
this message is that the trailer is not
detected. The final reason the system
could display this message is that an
internal condition for system operation
is not met that requires your vehicle to
return to manual control of the
steering.
How do I use a sticker if I have
previously setup a trailer with the
sensor? Disconnect the sensor wiring and add
a new trailer to the system and follow
the instructions for setup with a
sticker. See Applying the Trailer
Reversing Aid Sticker (page 448). If
your vehicle does not support the
sticker option, the touchscreen
instructs you to install the sensor
again.
What if I want to use a sensor for the
trailer instead of a sticker? Install the sensor and connect the
sensor wiring before adding the new
trailer to the system. You must
connect the sensor before you add the
trailer. If your vehicle did not come with
a sensor, you can purchase one from
your authorized dealer. What does it mean if the system does
not detect a trailer that is setup with a
sticker?
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 correctly operate. If
the system cannot initially detect the
trailer, it could be necessary for you to
change the lighting conditions by
moving your vehicle and trailer or
waiting until the conditions change.
See
Applying the Trailer Reversing
Aid Sticker (page 448). Some trailers
are not compatible with the sticker
and camera system. If the system
consistently does not detect the trailer
with the sticker setup, you may choose
to setup the trailer with a sensor.
Note: The system is designed to be used
with the same trailer connection every time
you choose the trailer from the touchscreen.
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 position and you
may need to repeat the trailer setup and
calibration process.
