2021 FORD EXPEDITION warning

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.

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.

•
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
reduce the system ’s ability to locate
the sticker. Check the measurements
entered into the system are correct.
Refer to the 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 does 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
display. Do not change them but
continue to confirm measurements.
Once you confirm the measurements,
the system prompts 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 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
294
Expedition (TB8) Canada/United States of America, enUSA, First-Printing Towing

sticker is placed correctly based on
steps 3 and the measurements were
made correctly according to Step 4.
The troubleshooting guide for trailer
measurements can also be reviewed
for help in making measurements.
• To change sticker location or change
trailer measurements, go into the
Towing menu, select trailer options,
select change trailer setting and then
select the change sticker option.
• If the sticker location needs to be
changed, the previous sticker must be
removed and a new sticker needs to
be placed on the trailer. ONLY ONE
STICKER SHOULD BE PLACED ON
THE TRAILER FOR PROPER
SYSTEM FUNCTION.
• 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 consistently shows Stop now take
control of steering warning:
• The system displays this warning when
it can no longer steer the vehicle and
you must take over steering. There are
four reasons why this warning displays
and additional information regarding
the reason for the warning is available
on the center display.
• The steering wheel is touched while
the system is controlling it. Avoid
touching the wheel during system
operation.
• The maximum speed for feature
operation is exceeded. System
performance is optimized at slower
speeds. Backup slowly. •
The sticker was lost by the camera
system. Once your vehicle is stopped
additional warnings indicate the sticker
was lost. Refer to sticker lost trouble
shooting tips.
• An internal condition for system
operation was not met which requires
your vehicle return to manual control
of the steering.
Note: The system is designed to be used
with the same trailer connection every time
the trailer is chosen from the selection
menu. Using a different drawbar or a
different pin hole (on drawbars with more
than one) when connecting the drawbar to
your vehicle affects the trailer
measurements. Take the measurements
again and update if required.
TRAILER SWAY CONTROL WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.

2.
Grab the trailer hitch cover at the edge
and rotate until the top of the trailer
hitch cover unsnaps from the bumper,
then remove the trailer hitch cover.
To install the trailer hitch cover: 1. Line up the snaps on the trailer hitch
cover to the holes on the bumper and
push forward until it snaps into place.
Hitches WARNING: Do not cut, drill, weld
or modify the trailer hitch. Modifying the
trailer hitch could reduce the hitch rating.
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.
Integrated Hitch Rating WARNING: Towing trailers beyond
the maximum recommended gross
trailer weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury. The standard integrated hitch has two
ratings depending on mode of operation:
•
Weight-carrying mode requires a draw
bar and hitch ball. The draw bar
supports all the vertical tongue load of
the trailer.
• Weight-distributing mode requires an
aftermarket weight-distributing
system, which includes draw bar, hitch
ball, spring bars and snap-up brackets.
This system distributes the vertical
tongue load of the trailer between the
truck and the trailer.
You must use a weight-distributing hitch
for weights above
6,000 lb (2,721 kg), up
to your vehicle's maximum towing
capacity.
Note: These are hitch ratings only. Actual
vehicle ratings are dependent on engine,
transmission and axle combinations.
Weight-distributing Hitch WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper
is higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may
cause unpredictable handling, and could
result in serious personal injury.
When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the trailer, on a level surface.
2. Measure the height to the top of your vehicle's front wheel opening on the
fender. This is H1.
3. Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
300
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE268260

4. Measure the height to the top of your
vehicle's front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight-distributing bars so that the
height of your vehicle's front wheel
opening on the fender is approximately
half the way down from H2, toward H1.
6. Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat steps 2-6.
When the trailer is level or slightly nose
down toward the vehicle:
• Lock the bar tension adjuster in place.
• Check that the trailer tongue securely
attaches and locks onto the hitch.
• Install safety chains, lighting, and trailer
brake controls as required by law or the
trailer manufacturer.
Safety Chains
Note: Do not attach safety chains to the
bumper. Always connect the safety chains
to the frame or hook retainers of your trailer
hitch.
Install trailer safety chains to the trailer
hitch as recommended by the
manufacturer. Cross the chains under the
trailer tongue and allow enough slack for
turning tight corners. Do not allow the
chains to drag on the ground. If the trailer safety chain hook has a latch,
make sure the latch fully closes.
Trailer Brakes
WARNING: Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1,500 lb (680 kg) when loaded.

Integrated Trailer Brake Controller (If
Equipped)
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. When used properly, the trailer brake
controller assists in smooth and effective
trailer braking by powering the trailer
’s
electric or electric-over-hydraulic brakes
with a proportional output based on the
towing vehicle ’s brake pressure.
The controller user interface consists of
the following:
A:
+ and - (Gain adjustment buttons):
Pressing these buttons adjusts the
controller's power output to the trailer
brakes in 0.5 increments. You can increase
the gain setting to 10.0 (maximum trailer
braking) or decrease it to 0 (no trailer
braking). The gain setting displays in the
message center. The controller shows gain setting, output
bar graph, and trailer connectivity status
in the information display. They appear in
the information display as follows:
•
Trailer Brake Controller Gain (without
trailer connected): Shows the current
gain setting during a given ignition cycle
and when adjusting the gain. This also
displays if you use the manual control
lever or make gain adjustments with
no trailer connected.
• Trailer Brake Controller Gain Output:
Displays when you push your vehicle's
brake pedal, or upon use of the manual
control. Bar indicators illuminate in the
information display to indicate the
amount of power going to the trailer
brakes relative to the brake pedal or
manual control input. One bar indicates
the least amount of output; six bars
indicate maximum output.
• Trailer Connected: Displays when the
system senses a correct trailer wiring
connection (a trailer with electric trailer
brakes) during a given ignition cycle.
• Trailer Disconnected: Displays,
accompanied by a single audible time,
when the system senses a trailer
connection and then a disconnection,
either intentional or unintentional,
during a given ignition cycle. It also
displays if a truck or trailer-wiring fault
occurs causing the trailer to appear
disconnected. This message can also
display if you use the manual control
lever without a trailer connected. After
disconnecting the trailer connector,
press the brake pedal for
approximately five seconds to allow
the system to detect and update the
trailer status.
