wheel FORD EXPEDITION 2019 Repair Manual

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.

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.
289
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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
279
).
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.

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

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.
295
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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
297
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-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.
