Make sure the trailer width is less than or
equal to 8.5 ft (2.6 m) and the length is
less than 33 ft (10.1 m). If you input values
higher, the system turns off.
Some trailers could cause a slight change
in system performance:
• Large box trailers could cause false
alerts to occur when driving next to
infrastructures or near parked cars. A
false alert could also occur while
making a 90-degree turn.
• Trailers that have a width greater than
8.5 ft (2.6 m)
at the front and have a
total length greater than 20 ft (6 m)
could cause delayed alerts when a
vehicle is passing at high speeds.
• Box trailers that have a width greater
than
8.5 ft (2.6 m) at the front could
cause early alerts when you pass a
vehicle.
• Clam shell or v-nose box trailers with
a width greater than
8.5 ft (2.6 m) at
the front could cause delayed alerts
when a vehicle traveling the same
speed as your vehicle merges lanes.

C You can set-up a trailer to work with the
blind spot information system through the
touchscreen. When setting up a trailer, a
sequence of screens appear asking for
trailer information.
1. Select type of trailer screen -
conventional, fifth wheel or gooseneck.
Note: The system only supports
conventional trailers.
2. Do you want to set up blind spot with trailer screen? If no, the system turns
off. If yes, the menu goes to the next
screen.
3. Is the width less than
9 ft (2.7 m) and
length less than 33 ft (10.1 m)? If no,
the system turns off. If yes, the menu
goes to the next screen.
4. Trailer width measurement. Measure the width at the front of the trailer. It is
not measured at the widest point of
the trailer. The maximum width at the
front of the trailer the system can
support is
8.5 ft (2.6 m).
Note: You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer is less
than
9 ft (2.7 m).
5. Trailer length measurement. The trailer
length is the distance between the
trailer hitch ball and the rear of the
trailer. The maximum length that the
system can support is
33 ft (10.1 m).
6. Enter the length of trailer. The default setting is
18 ft (5.5 m). Toggling up or
down using the menu buttons
increases or decreases the
measurement by
3 ft (1 m). Select a
length that is equal to or within 3 ft
(1 m) of the actual measured length.
For example, if the actual measure
length is
25 ft (7.5 m), toggle the length
in the menu to 27 ft (8.2 m). The
system setup saves when you enter the
length of the trailer.

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.

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.

– 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.

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.

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.
