for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
permanent damage. Typical steering and driving maneuvers will allow the
system to cool and steering assist will return to normal.
When a steering system error is detected, steering messages may appear
in the information display.
Steering Tips
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
AUTO LEVELING SUSPENSION SYSTEM (if equipped)
The automatic leveling suspension system is designed to improve ride,
handling and general vehicle performance during:
•Certain road conditions
•Steering maneuvers
•Braking
•Acceleration
•Towing
This system keeps the rear of your vehicle at a constant level through a
hydraulic pump inside each rear shock. Depending on the payload or
road surface conditions it will take approximately 2 miles (3.2 km) for
the leveling to complete.
If the loaded vehicle is not moved for approximately 12 hours, the
leveling system may bleed down to a lower height. This can be especially
apparent if a trailer is left attached to the parked vehicle for long periods
of time. You must drive your vehicle in order to re-level the suspension.
If a self-equalizing hitch is being used, your vehicle should be drive
approximately 2 miles (3.2 km) with the trailer prior to adjusting
(leveling) the hitch.

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 turn
on 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 messageTRAILER SWAY
REDUCE SPEEDappears 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 theLoad
Carryingchapter for specific loading information.
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 feet
2(3.39 meters2) trailer frontal area for vehicles equipped
with the standard towing package.
•60.0 feet
2(5.57 meters2) trailer frontal area for vehicles 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 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.

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 1500 pounds
(680 kilograms) when loaded.
Integrated Trailer Brake Controller (If Equipped)
WARNING:The Ford TBC has been verified to be compatible
with trailers having electric-actuated drum brakes (one to four
axles) and some electric-over-hydraulic (EOH) brakes. It will not
activate hydraulic surge-style trailer brakes. It is the responsibility of
the customer to ensure that the trailer brakes are adjusted
appropriately, functioning normally and all electric connections are
properly made. Failure to do so may result in loss of vehicle control,
crash or serious injury.
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.
Ford has tested the trailer brake controller to be compatible with several
major brands of electric-over-hydraulic trailer brakes. Contact an
authorized dealer for information on which brands you can use.
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 as follows: TBC GAIN = XX.X.
The controller shows gain setting, output bar graph, and trailer
connectivity status in the information display. They appear in the
Towing255
2015 Expedition(exd)
Owners Guide gf, 1st Printing, July 2014
USA(fus)

information display as follows:
•TBC GAIN = XX.X NO TRAILER: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.
•TBC GAIN = XX.X OUTPUT=//////:Displays when you push
your vehicle’s brake pedal, or when you use 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 chime, 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.
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 brakes. See
the followingProcedure for adjusting gainsection for instructions on
proper use of this feature. If you use the manual control while 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
while 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,TRAILER CONNECTEDappears 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 doesnotcover this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT:Displays in response to faults
sensed by the trailer brake controller, accompanied by a single chime. 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.
WIRING FAULT ON TRAILER:Displays when there is a short circuit
on the electric brake output wire. If theWIRING FAULT ON TRAILER
message displays, accompanied by a single chime, with no trailer
Towing257
2015 Expedition(exd)
Owners Guide gf, 1st Printing, July 2014
USA(fus)

connected, the problem is with your vehicle wiring 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 theWorkshop 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 turn the engine off, the controller output is disabled and
the display and module shut down. The controller module and display
turn on when you turn 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.
