If a message regarding a blocked sensor
or camera appears in the information
display, something is obstructing the radar
signals or camera images. The radar sensor
is behind the fascia cover in the center of
the lower grille. With a blocked sensor or
camera, the system may not function, or
performance may reduce. See
Pre-Collision Assist – Information
Messages (page 404).
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
could change. This could cause missed or
false vehicle detections. Have your vehicle
serviced to have the radar checked for
proper coverage and operation. Note:
If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor recalibrates successfully.

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.

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

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.

OFF-ROAD DRIVING
WHAT IS OFF-ROAD DRIVING
Off-road driving is driving your vehicle on
unsurfaced roads or trails, made from dirt,
rocks, sand and mud.
OFF-ROAD DRIVING
PRECAUTIONS - RAPTOR
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
Before going off-road driving, consult with
all the appropriate government entities to
determine where you are legally allowed
to operate your vehicle and what permits
or registrations are required to do so.
Inspect your vehicle before and after any
off-road driving.
Familiarize yourself with the dimensions
of your vehicle including approach angles,
breakover angles, and ground clearance.
Also familiarize yourself with the features
of your vehicle. Some of these features
such as drive modes and cameras can
improve your off-road driving experience.
Secure loose objects inside your vehicle
and in the cargo area.
BASIC OFF-ROAD DRIVING
TECHNIQUES - RAPTOR
Grip the steering wheel with your thumbs
on the outside of the rim. This reduces the
risk of injury due to abrupt steering wheel
motions that occur when negotiating rough
terrain. If you are driving in a dusty area, be sure to
leave ample distance between your vehicle
and any other vehicles to allow for
adequate vision.
BASIC OFF-ROAD DRIVING
TECHNIQUES
Off-road Driving Hints
Before taking your vehicle off-roading, a
basic vehicle inspection should be done to
make sure that the vehicle is in top working
condition. It is always recommended that
at least two vehicles are used while
off-roading. The buddy system helps make
sure that help is close at hand should a
vehicle become stuck or damaged. It is also
wise to take supplies such as a first aid kit,
supply of water, tow strap, cell or satellite
phone with you any time an off-road
excursion is planned.
1. Grip the steering wheel with thumbs
on the outside of the rim. This will
reduce the risk of injury due to abrupt
steering wheel motions that occur
when negotiating rough terrain.
2. Throttle, brake and steering inputs should be made in a smooth and
controlled manner. Sudden inputs to
the controls can cause loss of traction
or upset the vehicle, especially while
on loose terrain or while crossing
obstacles such as rocks or logs.
3. Look ahead on your route noting upcoming obstacles, or any other
factors which may indicate a change
in available traction, and adjust the
vehicle speed and route accordingly.
4. When driving off-road, if the front or rear suspension is bottoming out
and/or excessive contact with the
skid-plates is encountered, reduce
vehicle speed to avoid potential
damage to the vehicle.

When operating your vehicle with a
snowplow:
•
Do not exceed 45 mph (72 km/h).
• Your engine could run at a higher
temperature than normal.
•If you are driving more than
15 mi
(24 km) at temperatures above
freezing, angle the plow blade
either full left or full right to provide
maximum airflow to the radiator.
• If you are driving less than
15 mi
(24 km) at speeds up to 45 mph
(72 km/h) in cold weather, you do
not need to worry about blade
position to provide maximum
airflow.
• Shift to 4L when plowing in small areas
at speeds below
5 mph (8 km/h).
• Shift to
4H when plowing larger areas
or light snow at higher speeds above
5 mph (8 km/h)
. Do not exceed
15 mph (24 km/h).
• Do not shift the transmission from a
forward gear to reverse (R) until the
engine is at idle and the wheels have
stopped.
Note: Careless or high-speed driving when
snowplowing, which results in significant
vehicle decelerations, can deploy the airbag.
Such driving also increases the risk of
accidents.
Note: Drive your vehicle at least
500 mi
(800 km) before using your vehicle for
snowplowing.
Note: Follow the severe duty schedule for
engine oil and transmission fluid change
intervals. See
Special Operating
Conditions Scheduled Maintenance (page
675
). SNOWPLOW MODE
WHAT IS SNOWPLOW MODE
Snowplow mode reduces vehicle electrical
load to allow the electrical system to have
sufficient power to support residential
snowplow use.
SWITCHING SNOWPLOW MODE
ON AND OFF
