TOWING A TRAILER
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. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 320).
Some vehicles may have the
ability to modify trailer towing
features. See Towing (page 279).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop and load
capacity. When both the
loaded vehicle and trailer are
connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
273).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

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 293).
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 279). 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 113).
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.

Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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).
282
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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.
283
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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.
284
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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.
