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.

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.
284
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Towing

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
274
).
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 weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment
weight.
3. This equals the maximum
loaded trailer weight for this
combination.
285
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Towing

Note:
The trailer tongue load
figures into the payload for your
vehicle. Reduce the total payload
by the final trailer tongue weight. Consult an authorized dealer to
determine the maximum trailer
weight allowed for your vehicle if
you are not sure. Maximum Trailer

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.
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.
289
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- TowingE265060

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.
B: Manual control lever: Slide the control
lever to the left to turn on the trailer's
electric brakes independent of the tow
vehicle's. If you use the manual control
when the brake is also applied, the greater
of the two inputs determines the power
sent to the trailer brakes.
• Stop lamps: Using the manual control
lever illuminates both the trailer brake
lamps and your vehicle brake lamps
except the center high-mount stop
lamp, if you make the proper electrical
connection to the trailer. Pressing your
vehicle brake pedal also illuminates
both trailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note: Only perform this procedure in a
traffic-free environment at speeds of
approximately
20– 25 mph (30–40 km/h).
The gain setting sets the trailer brake
controller for the specific towing condition.
You should change the setting as towing
conditions change. Changes to towing
conditions include trailer load, vehicle load,
road conditions and weather.
The gain should be set to provide the
maximum trailer braking assistance when
making sure the trailer wheels do not lock
when using the brakes. Locked trailer
wheels may lead to trailer instability.
1. Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions. 3. When you plug in a trailer with electric
or electric-over-hydraulic brakes, a
message confirming connection
appears in the information display.
4. Use the gain adjustment (+ and -) buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of 6.0 is a good
starting point for heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed
of
20– 25 mph (30–40 km/h) and
squeeze the manual control lever
completely.
6. If the trailer wheels lock up, indicated by squealing tires, reduce the gain
setting. If the trailer wheels turn freely,
increase the gain setting. Repeat steps
5 and 6 until the gain setting is at a
point just below trailer wheel lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Explanation of Information Display
Warning Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your Ford warranty does not cover
this diagnosis if the fault is with the trailer.
A message indicating a trailer brake
module fault may display in response to
faults sensed by the trailer brake controller,
accompanied by a single tone. If this
message appears, contact an authorized
dealer as soon as possible for diagnosis
and repair. The controller may still
function, but performance may be
degraded.
A message indicating a trailer wiring fault
may display when there is a short circuit
on the electric brake output wire. If this
message displays, accompanied by a
single tone, with no trailer connected, the
problem is with your vehicle wiring
291
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Towing

between the trailer brake controller and
the 7-pin connector at the bumper. If the
message only displays with a trailer
connected, the problem is with the trailer
wiring. Consult your trailer dealer for
assistance. This can be a short to ground
such as a chaffed wire, short to voltage
such as a pulled pin on trailer emergency
breakaway battery, or the trailer brakes
may be drawing too much current.
Points to Remember
Note:
Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result.
• Adjust gain setting before using the
trailer brake controller for the first time.
• Adjust gain setting, using the procedure
above, whenever road, weather and
trailer or vehicle loading conditions
change from when the gain was initially
set.
• Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in reduced stability of trailer and tow
vehicle.
• The trailer brake controller is equipped
with a feature that reduces output at
vehicle speeds below 11 mph (18 km/h)
so trailer and vehicle braking is not jerky
or harsh. This feature is only available
when applying the brakes using your
vehicle's brake pedal, not the
controller. •
The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.
• Your vehicle's brake system and the
trailer brake system work
independently of each other. Changing
the gain setting on the controller does
not affect the operation of your
vehicle's brakes whether you attach a
trailer or not.
• When you switch the engine off, the
controller output is disabled and the
display and module shut down. The
controller module and display turn on
when you switch the ignition on.
• The trailer brake controller is only a
factory-installed or dealer-installed
item. Ford is not responsible for
warranty or performance of the
controller due to misuse or customer
installation.
Trailer Lamps WARNING: Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, direction indicators and hazard lights
are working.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not tow during the first 1,000 mi
(1,600 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed when towing may reduce
this tendency. •
If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant if the axle is not already
filled with it. See
Capacities and
Specifications (page 380).
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a slope. However, if
you must park on a slope:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in size,
tread-type, or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire
label or Safety Compliance label for
limitations when using these tires.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
293
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Towing

Exceeding these limits may allow water to
enter vehicle components:
•
Causing internal damage to the
components.
• Affecting driveability, emissions and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS WARNING: If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed.
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
See
Climate Control (page 139).
Follow these guidelines if you have a need
for recreational towing, for example towing
your vehicle behind a motorhome. These
guidelines prevent damage to your
transmission.
Two-wheel Drive Vehicles
You cannot tow a two wheel drive vehicle
with any wheels on the ground as vehicle
or transmission damage may occur. You
must tow your vehicle with all four wheels
off the ground, for example when using a
car-hauling trailer. Four-wheel Drive Vehicles Without 4x4
LOW
If your vehicle is not equipped with 4x4
