Ford Expedition (2018 year). Manual — part 67

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

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.

This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE
SPEED

appears in the information display.

The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See Towing (page
263).

RECOMMENDED TOWING
WEIGHTS

Note:

Do not exceed the trailer

weight for your vehicle
configuration listed in the chart
below.

Note:

Make sure to take into

consideration trailer frontal area.
Do not exceed 36.5 feet² (3.39
meters²) if your vehicle is equipped
with the standard towing package,
or 60 feet² (5.57 meters²) if your
vehicle is equipped with the
optional heavy duty package.

Note:

Exceeding this limitation

may significantly reduce the
performance of your towing
vehicle. Selecting a trailer with a
low aerodynamic drag and rounded
front design helps optimize
performance and fuel economy.

Note:

For high altitude operation,

reduce the gross combined weight
by 2% per 1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point.

Note:

Certain states require

electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as the
vehicle’s electrical system may not
include the wiring connector
needed to activate electric trailer
brakes.

Your vehicle may tow a trailer
provided the maximum trailer
weight is less than or equal to the
maximum trailer weight listed for
your vehicle configuration on the
following chart.

To calculate the maximum loaded
trailer weight for your vehicle:
1. Start with the gross combined

weight rating for your vehicle
model and axle ratio. See the
following chart.

2. Subtract all of the following

that apply to your vehicle:
•

Vehicle curb weight

•

Hitch hardware weight, such
as a draw bar, ball, locks or
weight distributing

•

Driver weight

•

Passenger(s) weight

•

Payload, cargo and luggage
weight

•

Aftermarket equipment
weight.

3. This equals the maximum

loaded trailer weight for this
combination.
