TRAILER REVERSING AIDS (IF
EQUIPPED)
Pro Trailer Backup Assist™ WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving. WARNING:
This system is an extra
driving aid. It does not replace your
attention and judgment, or the need to
apply the brakes. This system does NOT
automatically brake your vehicle. If you
fail to press the brake pedal when
necessary, you may collide with another
vehicle.
Note: The system is not a substitute for
safe driving practices.
Note: You must always be aware of the
vehicle and trailer combination and the
surrounding environment.
Note: The system does not detect or
prevent the vehicle or trailer from making
contact with obstacles in the surrounding
environment. Note:
Keep in mind that the front end of
the vehicle swings out when changing the
direction of the trailer.
Note: The system relies on user
measurements to determine sticker
placement and system limits. It is critical to
take the key measurements correctly.
Incorrect measurements can result in the
improper function of the system up to and
including contact between the vehicle and
trailer.
Note: The system limits vehicle speed when
backing up. The system is not a replacement
for proper use of the throttle and brake
pedals.
Principle of Operation
This feature helps you to steer your vehicle
when backing up with a trailer attached.
Turn and hold the control knob in the
direction you want the trailer to go and the
system takes over the steering. This allows
you to focus on checking the mirrors and
operating the brake and accelerator.
Each trailer you use with your vehicle has
to be setup once.
You must take care to follow the setup
process accurately, to make sure the
sticker is placed correctly.
Contact your dealership if you need
assistance in setting up your trailer.
Setting Up Pro Trailer Backup
Assist
Note: Once you have entered a trailer's
information into the system, it is stored for
easy recall. A maximum of 10 trailers can be
added to the system.

Step 1: Position your Vehicle and Trailer
Hitch your conventional trailer to your
vehicle. See Essential Towing Checks
(page 299).
Park your vehicle and hitched trailer on a
level surface.
For best results, make sure that your trailer
rides level with the ground when you hitch
it to your vehicle. More information on
selecting your towbar is available in the
Towing section.
See Towing (page 285). Make sure your vehicle and the trailer are
in line with each other. You can do this by
driving straight forward.
Step 2: Follow the Information Display
Prompts
Press the button to turn the system on. 1.
Select the option to add a trailer in the
instrument cluster menu, using the
steering wheel control. See
General
Information (page 119).
2. Add a personalized name for the trailer
using the screen prompts. Use the
down arrow to scroll to the desired
letter and then press the right arrow to
advance to the next letter. Press OK to
continue.
3. Select the type of trailer brake system for the trailer you are adding.
4. Select the brake effort level for the trailer.
Note: The default option is low. This is
recommended for most trailers. If the
trailer's brakes require more initial voltage,
or if you prefer more aggressive braking then
select the other options as required.
287
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE247482 E247481 E253721

Some examples of conventional type
trailers are shown below.
Note:
You cannot use the system with the
types of trailers marked with the cross.
The system only works with
conventional trailers. It does not work
with other types including gooseneck
and fifth wheel. Follow the information display prompts.
Step 3: Place the Sticker on the Trailer
Frame
The supplied sticker must be placed in an
area visible by the rear view camera.
Note:
The cargo and trailer hookup lamps
turn on automatically to improve visibility.
Note: An assistant can help to carry out the
following procedure.
Note: Make sure nothing can obstruct the
rear view camera's view of the sticker. For
example, items such as a jack handle or
wiring.
Note: Position the sticker on a flat, dry and
clean horizontal surface. For best results
apply the sticker when temperatures are
above 32°F (0°C).
Note: Do not move stickers after they are
placed. Do not re-use any stickers if
removed. Note:
Additional stickers may be purchased
through your Ford Dealers parts department. Use the supplied measurement card, a
tape measure and pen to carefully mark
the area where to attach the sticker
(supplied in the back cover pocket of your
quick start guide). Make sure the whole
sticker is within the zone between the two
arcs or distance markers on the diagram,
and is also visible in the rear view camera
display.
Step 4: Take Measurements
After the sticker is correctly placed on the
trailer you must take some key
measurements.
Note:
Accurate measurements must be
taken for the system to operate properly.
Note: When rounding in inches, round
upward if the measured length is a quarter
inch or greater. Round downward if the
measured length is less than a quarter inch.
For example
12.25 in (31.11 cm) would be
rounded up to 12.50 in (31.75 cm). 12.13 in
(30.8 cm) would be rounded down to
12.00 in (30.48 cm).
Note: When rounding in centimeters, round
to the nearest whole centimeter. If the
measurement is less than
0.2 in (0.5 cm)
round downward. If the measurement is
more than or equal to 0.2 in (0.5 cm) round
upward. For example, 11.9 in (30.3 cm)
would be rounded down to
11.8 in (30 cm).
12.0 in (30.5 cm) would be rounded up to
12.2 in (31 cm).
288
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE209766 E209805

Note:
Use consistent metric or imperial
units as required by your country or vehicle.
Record the four key distances (A, B, C, D)
as required by the measurement card.
Record the trailer name for these
measurements. Distance A
The horizontal distance from the bumper
to the center of the ball hitch on the trailer.
Distance B
The horizontal distance from the center of
the ball hitch to the center of the sticker.
Distance C
The distance from the rear view camera to
the center of the sticker.
Distance D
The horizontal distance from the bumper
to the center of the trailer axle (single axle
trailers), or the center of the axles (trailers
with dual axles or more). Note:
If the distance ends in anything less
than one half of an inch, round down to the
current whole inch. If a distance ends in one
half or greater of an inch, round up to the
next whole inch. For example, 12.3 in
(31.12 cm) would be rounded down to 12 in
(30.48 cm). 12.5 in (31.75 cm) would be
rounded up to 13 in (33 cm).
Step 5: Enter Measurements Using the
Information Display
Using the recorded measurements, enter
the required data into the system. Follow
the on screen prompts to enter each of the
measurements taken in step 4. When all
four distances have been entered, a
confirmation display appears. Check the
values are correct before proceeding, or go
back to change any if required.
Step 6: Confirming the Sticker Location
Check the rear view camera display to see
if the sticker is identified by the system and
marked with a red circle.
Confirm that the red circle is correctly
located over the sticker image in the
display. The on screen prompt asks you to
confirm this.
Note: If the system cannot locate the
sticker try cleaning the camera lens, and
also make sure the sticker is within the green
zone as indicated in step 3.
Calibrating the System
To complete setup, drive your vehicle
straight forward between 4 mph (6 km/h)
and
24 mph (39 km/h) following the on
screen prompt.
Note: Check your measurements to make
sure you measured from the correct points.
Note: If you move the steering wheel during
this procedure, the calibration pauses.
Note: We recommend that you do not do
this at night.
289
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE247545

A message displays during calibration and
after calibration is complete.
Using Pro Trailer Backup Assist
To use the system press the button and
select the required trailer from the display.
When the sticker is located, the display
prompts you to shift into reverse (R). The
system turns on.
Note:
The system does not function if your
hands are on the steering wheel. Remove
your hands to resume operation.
Follow the screen prompts to steer your
vehicle and trailer.
Note: You may have to drive forward to
straighten the trailer. Take your hands off the steering wheel and
turn the Pro Trailer Backup Assist control
knob instead. The knob acts as the steering
control for the trailer.
Note:
The more you turn the knob, the
sharper the trailer turns. Turn and hold counterclockwise to make
the trailer go left.
Turn and hold clockwise to make the trailer
go right.
Note:
Practice maneuvering with the
system in a safe open area first.
Note: Try backing up in a straight line and
then turning the knob slowly in the direction
you want to go.
Note: Quickly turning and releasing the
knob results in a jerky movement of the
vehicle.
290
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE253721 E246992 E246991

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 bumper to hitch
ball center measurement of 4 in
(10 cm) to 11 in (28 cm) when installed.
Do not attempt to use drawbars that
have a length outside this range as the
system performance degrades and
could cause improper system function.
• Make sure that the measurement being
made is the horizontal distance only
from bumper and the hitch ball center.
A straight line distance that includes
any vertical rise or drop increases the
measurement and makes it inaccurate.
Inaccurate measurements degrade
system performance and could cause
improper system function. See step 4
of the setup instruction to review
measurement instructions.
291
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE246993

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 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
increases the measurement and
causes 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 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 the bumper 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 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 straight
behind your vehicle. Any steering input or
trailer movement pauses the calibration.
292
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Towing

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 prevents 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 is necessary
to remove the sticker from its current
location if the obstruction cannot be
cleared and place a new sticker that is
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 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.
