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.

TOWING A TRAILER
PRECAUTIONS
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: Make sure that
the vertical load on the tow ball
is between the minimum and
maximum recommended weight
at all times. 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. WARNING:
The anti-lock
brake system does not control
the trailer brakes.
TRAILER BRAKE
PRECAUTIONS WARNING:
Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase. WARNING:
Do not tow a trailer
fitted with electric trailer brakes unless
your vehicle is fitted with a compatible
aftermarket electronic trailer brake
controller. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. For additional information and
assistance, we recommend that you
contact an authorized dealer.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.

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

WHAT IS THE MAXIMUM LOADED
TRAILER WEIGHT
The maximum loaded trailer
weight is the highest possible
weight of a fully loaded trailer the
vehicle can tow.
CALCULATING THE MAXIMUM
LOADED TRAILER WEIGHT FOR
YOUR VEHICLE
1. Start with the gross combined
weight rating for your vehicle
model and axle ratio.
2. Subtract all of the following
that apply to your vehicle:
• Vehicle curb weight.
• Hitch hardware weight, for
example a draw bar, ball, locks
or weight distributing hardware. •
Driver weight.
• Passenger weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment weight.
This equals the maximum loaded
trailer weight for this combination.
Note: The trailer tongue load is
considered part of the payload for
your vehicle. Reduce the total
payload by the final trailer tongue
weight.
Note: Consult an authorized dealer
to determine the maximum trailer
weight allowed for your vehicle if
you are not sure.

WHAT IS THE INTEGRATED
TRAILER BRAKE CONTROLLER
The trailer brake controller assists in
smooth and effective trailer braking based
on the towing vehicle
’s brake pressure.
INTEGRATED TRAILER BRAKE
CONTROLLER PRECAUTIONS WARNING: Use the integrated
trailer brake controller to properly adjust
the trailer brakes and check all
connections before towing a trailer.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
• Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in reduced stability of trailer and tow
vehicle.
• The trailer brake controller is only a
factory-installed or dealer-installed
item. Ford is not responsible for
warranty or performance of the
controller due to misuse or customer
installation.
Note: Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result. USING THE INTEGRATED
TRAILER BRAKE CONTROLLER
1.
Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred. Your
vehicle warranty does not cover issues with
your trailer.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
Note: Select default mode if the trailer has
surge brakes, or no brakes at all. The system
has no effect on the braking performance
of the trailer in either of these cases.
Note: If a trailer is connected by a four-pin
connector, the trailer braking function will
not be supported.
3. When you plug in a trailer with electric or electric-over-hydraulic brakes, a
message confirming connection
appears in the information display.
4. Use the gain adjustment to find the desired starting point. A gain setting of
6.0 is a good starting point for heavier
loads.
Note: Use the following steps to adjust the
gain setting whenever road, weather and
trailer, or vehicle loading conditions, change
from when you initially set the gain.
5. In a traffic-free environment, tow the trailer on a dry, level surface and
squeeze the manual control lever
completely.
