Ford F-150 (2018 year). Manual - part 70

Release the knob when the trailer is
moving in the direction you want. Control
the accelerator and brakes while the
system steers your vehicle automatically
to keep the trailer moving straight back.

Note: You may have to use the knob to
correct the trailer direction when attempting
to move the trailer straight back under some
conditions.

Note: Your vehicle speed is automatically
limited.

Note: When you release the knob or turn it
to the center position, your vehicle follows
the trailer's path.

Troubleshooting

Note: 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 operate correctly.

Setup

The system is designed to be used with a
wide variety of trailers. However there are
some trailers that do not have a proper
surface and location to mount the sticker.
These trailers are not supported. Attempts
to place the sticker on a surface that does
not meet the sticker placement
requirement listed in Step 3 of the setup
instruction or entering inaccurate
measurements to proceed through setup
can result in improper system function.

Accurate measurements are critical to
correct system function. If you need to
check measurements entered or change
them you can access them through the
trailer menus in the instrument cluster.
Choose the option to change the sticker
from the change trailer settings menu. It is
not necessary to remove the sticker if you
are just reviewing or changing
measurements.

The following menu warnings or difficulties
may occur during setup. Tips to resolve
them are listed below.

Note: If you still experience issues with the
system's ability to detect the sticker, see
the information in the next section regarding
sticker lost during system operation.

Measurement A has reached maximum or
minimum value:
•

The system is designed to work with
drawbars that have a license plate to
hitch ball center measurement of 9 in
(23 cm) to 16 in (41 cm) when installed.
Do not attempt to use drawbars that
have a length outside this range as the
system performance will be degraded
and could cause improper system
function.

•

Make sure that the measurement being
made is the horizontal distance only
from license plate and the hitch ball
center. A straight line distance that
includes any vertical rise or drop will
increase the measurement and make
it inaccurate. Inaccurate
measurements will degrade system
performance and could cause improper
system function. See step 4 of the
setup instruction to review
measurement instructions.

Measurement B has reached maximum or
minimum value:
•

Make sure that the sticker placement
instruction in step 3 of the setup has
been followed. Stickers placed outside
the allowed zone will adversely affect
the system performance and could
cause improper feature function.

•

Make sure that the measurement being
made is the horizontal distance only
from center of sticker to the hitch ball
center. A straight line distance that
includes any vertical rise or drop will
increase the measurement and cause
an inaccurate value to be entered into
the system. See step 4 of the setup for
additional measurement instructions.

Measurement C has reached maximum or
minimum value:
•

Make sure that the sticker placement
instructions in step 3 of the setup have
been followed. Stickers placed outside
the allowed zone will adversely affect
the system performance and could
cause improper feature function. If you
have met all the criteria for sticker
placement and you see this message
this sticker is either too far below or too
close to the camera to properly
recognize the sticker. In order for the
system to operate correctly the sticker
height must be lowered if you receive
the minimum warning or the sticker
height must be raised if you receive the
maximum warning.

•

Only one sticker can be placed on the
trailer for correct system function. The
previous sticker must be removed or
covered so only one sticker is visible to
the camera.

•

Measurement B and C must be
measured again if a new sticker is
placed on the trailer.

Measurement D has reached maximum or
minimum value:
•

Make sure that the measurement being
made is the horizontal distance only
from tailgate to the center of the single
axle or the center of all the axles on the
trailer. See step 4 of the setup for
additional measurement instructions.
The TBA system does not support
trailer lengths outside the range
allowed by the information display.

System is circling something beside the
sticker or system cannot find the sticker:
•

Make sure the rear camera is clean and
the sticker is clearly visible in the
camera image. Clean the camera and
sticker if necessary.

•

The camera system uses the entered
measurements to help locate the
sticker. Inaccurate sticker
measurements will degrade the
system’s ability to locate the sticker.
Verify the measurements entered into
the system are accurate.

•

Remove the incorrectly circled label or
decal if possible.

•

If you cannot resolve the issue a new
sticker location should be tried. The
sticker location must still meet the
requirements noted in step 3 of the
setup instructions. Only one sticker can
be placed on the trailer for correct
system function. The previous sticker
must be removed or covered so only
one sticker is visible to the camera.

Calibration

The system monitors various vehicle
parameters to ensure your vehicle is being
driven straight and the trailer is straight
behind your vehicle. Any steering input or
trailer movement will pause the calibration.

For best results:
•

Use a long, straight, smooth and level
road when attempting to calibrate.

•

Drive straight forward.

•

Drive between 4 mph (6 km/h) and
24 mph (39 km/h).

System Operation

The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below.

The system is not available:
•

The system relies on many
sub-systems in your vehicle to operate
correctly. If those sub-systems are not
operating correctly the system may not
be available.

•

Low battery voltage is a condition
which will prevent the system from
operating. Please make sure the
battery is correctly charged if the
system is not available.

•

You may need to drive your vehicle
straight forward above 25 mph
(40 km/h) before the system is
available again.

•

If the message still displays take your
vehicle to an authorized dealer for
service.

Sticker lost:
•

If the system cannot initially find the
sticker, it may be necessary for you to
change the lighting conditions by
moving the vehicle and trailer or
waiting until conditions change.

•

Check for the following if you receive
the lost sticker message while using
the system.

•

Stop your vehicle as soon as the
message displays.

•

Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.

•

Clean the sticker and camera to make
sure they are unobstructed.

•

Clean the lens with a soft, lint-free
cloth and water.

•

Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the
sticker, and then wipe clean with a soft
cloth.

•

Remove any items that may be
blocking the view of the sticker.
Depending on your trailer configuration
and any equipment mounted to your
trailer it is possible for the sticker to be
blocked from view of the camera as it
rotates on the hitch ball but not be
blocked during setup. Remove the
obstruction if possible. It will be
necessary to remove the sticker from
it’s current location if the obstruction
cannot be cleared and place a new
sticker that will be visible to the camera
in all positions of the trailer behind your
vehicle.

•

Placing the sticker on a surface angled
away from the vehicle reduces
performance. Use a drawbar that
positions the trailer level to the ground
when attached to the vehicle. This
typically provides a level surface to
mount the sticker. Place the sticker on
a bracket or other object when no level
surface is available.

•

Make sure the entire sticker is on a flat
surface that is completely visible to the
camera. Do not fold the sticker over an
edge on the trailer frame. This can
degrade performance.

•

Shadows on the sticker may effect
tracking performance under some
lighting conditions. Moving the sticker
to another location within the allowed
placement area may improve
performance. Use the change sticker
option in your Towing menu if you
move the sticker.

•

You can change your sticker location
by going into the Towing menu,
selecting trailer options, selecting
change trailer settings and then
selecting the change sticker option. The
previous sticker must be removed.
ONLY ONE STICKER SHOULD BE
PLACED ON THE TRAILER FOR
CORRECT SYSTEM FUNCTION.

•

The camera system uses the entered
measurements to help locate the
sticker. Inaccurate measurements will
reduce the system’s ability to locate
the sticker. Check the measurements
entered into the system are correct.
Refer to step 4 of Pro trailer backup
Assist setup for instructions on
measurements.

•

You can change your measurement by
going into the Towing menu, selecting
trailer options, selecting change trailer
setting and then selecting the change
sticker option. Disregard the prompt to
remove this sticker and continue to the
next step if you only plan to update the
measurements for the current sticker
location.

System will not backup straight:
•

Factors such as the drawbar
connection to the hitch receiver, road
camber, road grade and compliance in
the trailer suspension can influence
how straight the system is able to back
your trailer when the knob is not turned.
You can compensate for the trailer
drifting to the right or left by slowly
turning the Pro Trailer Backup Assist
knob until the trailer is following your
desired path and then holding the knob
in that position. If you would like to
recalibrate the system for straight
backing, you can do so with the
following procedure.

•

Go into the Towing menu, select trailer
options, select change trailer setting
and then select the change sticker
option. Your saved measurements will
be displayed. Do not change them but
continue to confirm measurements.
Once you confirm the measurements,
the system will then prompt you to
perform the calibration procedure.

System consistently shows Stop Now Max
trailer angle reached warning:
•

The system uses your measurements
to determine sticker position and
establish system limits. Accurate
sticker placement and trailer
measurements will provide the best
system performance. If you are
consistently receiving this warning it is
likely there is an issue with sticker
placement or the entered
measurements. Make sure that the
