Ford 2016 F-150 Owner's Manual page 261

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: 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
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.

Towing
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
(229 mm) to 16 in (406 mm) 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 veritical 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.
