Ford Expedition (2018 year). Manual — part 66

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.

E247545

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).

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.

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.

E253721

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.

E246992

Turn and hold counterclockwise to make
the trailer go left.

E246991

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.

E246993

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.

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.
