WHAT IS THE MAXIMUM LOADED
TRAILER WEIGHT
The maximum loaded trailer weight is
the highest possible weight of a fully
loaded trailer the vehicle can tow.
CALCULATING THE MAXIMUM
LOADED TRAILER WEIGHT FOR YOUR
VEHICLE
1.
Start with the gross combined weight
rating for your vehicle model and
axle ratio. 2.
Subtract all of the following that
apply to your vehicle:
• Vehicle curb weight.
• Hitch hardware weight, for example
a draw bar, ball, locks or weight
distributing hardware.
• Driver weight.
• Passenger weight.
• Payload, cargo and luggage weight.
• Aftermarket equipment weight. This equals the maximum loaded trailer
weight for this combination.
Note:
The trailer tongue load is
considered part of the payload for your
vehicle. Reduce the total payload by the
final trailer tongue weight.
Note: Consult an authorized dealer to
determine the maximum trailer weight
allowed for your vehicle if you are not
sure.

WHAT IS THE INTEGRATED
TRAILER BRAKE CONTROLLER
The trailer brake controller assists in smooth
and effective trailer braking based on the
towing vehicle
’s brake pressure.
INTEGRATED TRAILER BRAKE
CONTROLLER PRECAUTIONS WARNING: Use the integrated trailer
brake controller to properly adjust the
trailer brakes and check all connections
before towing a trailer. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. •
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 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.
Note: Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result. USING THE INTEGRATED TRAILER
BRAKE CONTROLLER
1.
Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred. Your
vehicle warranty does not cover issues with
your trailer.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
Note: Select default mode if the trailer has
surge brakes, or no brakes at all. The system
has no effect on the braking performance of
the trailer in either of these cases.
Note: If a trailer is connected by a four-pin
connector, the trailer braking function will
not be supported.

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 to find the desired starting point. A gain setting of
6.0 is a good starting point for heavier
loads.
Note: Use the following steps to adjust the
gain setting whenever road, weather and
trailer, or vehicle loading conditions, change
from when you initially set the gain.
5. In a traffic-free environment, tow the trailer on a dry, level surface 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.
Note: Only perform this procedure at speeds
of approximately 20–25 mph (30–40 km/h). Note:
The trailer brake controller reduces
output at vehicle speeds below 11 mph
(18 km/h) so that 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.
Note: 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.
Note: With the proper electrical connection,
pressing your vehicle brake pedal or using
the manual control lever illuminates both
trailer and vehicle brake lamps.
Note: 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. Adjusting the Trailer Brake Gain
Increase or decrease the amount
of gain in set increments.
A
Slide the control to engage the
trailer brakes.
B
Note: Adjust gain setting before using the
trailer brake controller for the first time.

Note:
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.
Note: Setting adjustments are saved when
a trailer profile is selected.
ADJUSTING THE INTEGRATED
TRAILER BRAKE CONTROLLER
MODE
Select the correct integrated trailer brake
controller mode option using the
touchscreen. Note:
Trailer brake gain settings are saved
to the active trailer profile.
Selecting the Trailer Brake Type
1. Press Default for trailers with
electromagnetic drum brake systems or
press Electric over Hydraulic for trailers
with electrically actuated hydraulic brake
systems.
2. Press
Save.
Selecting the Trailer Brake Effort
1. Select a setting for your trailer. Note:
The default value is
Low and is the
recommended setting for most trailers.
Select a different setting if your trailer's
brakes require more initial voltage, or you
prefer more aggressive trailer braking.
2. Press
Save.

HOW DOES TRAILER SWAY
CONTROL WORK
The system applies the brakes to the
individual wheels and reduces engine torque
to aid vehicle stability.
If the trailer begins to sway, the stability
control lamp flashes and the message Trailer
Sway Reduce Speed appears in the
information display.
Stop your vehicle as soon as it is safe to do
so. Check the vertical weight on the tow ball
and trailer load distribution. TRAILER SWAY CONTROL
PRECAUTIONS 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 only activates when
significant trailer sway occurs.
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. SWITCHING TRAILER SWAY
CONTROL ON AND OFF
1. Press
Features on the touchscreen.
2. Press

3. Switch
Trailer Sway Control on or off.
