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.
Note: See
Recommended
Towing Weights (page 235).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 263).
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
229).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

Note: Make sure to take into
consideration trailer frontal area.
Vehicles equipped with the Trailer
Tow Package or the Heavy Duty
Payload Package should not
exceed 55 ft² (5.1 m²) trailer frontal
area.
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 your
vehicle's electrical system may not
include the wiring connector
needed to use 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 charts.

Follow these guidelines for safe towing:
•
Do not tow a trailer until your vehicle
has covered at least 1,000 mi
(1,600 km). See Breaking-In (page
247).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the correct
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See
Scheduled
Maintenance (page 446).
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
Refer to
Load Carrying for load
specification terms found on the tire label,
Safety Compliance label and instructions
on calculating your vehicle's maximum
load. See
Load Limit (page 229).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Trailer Towing Connector
(If Equipped) Your vehicle is fitted with both a 7 pin and
4 pin trailer wiring connector.
239
2021 Transit (TTH) Canada/United States of America, MK3J 19A321 AA enUSA, Edition date: 202010, Second-Printing TowingE163167

When attaching the trailer wiring connector
to your vehicle, only use a correctly fitting
connector that works with the vehicle and
trailer functions. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the correct wiring
connector and works correctly with your
vehicle.

Tow Hitch WARNING: Do not exceed the
lowest rating capacity for your vehicle or
trailer hitch. Overloading your vehicle or
trailer hitch can impair your vehicle
stability and handling. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not cut, drill, weld
or modify the trailer hitch. Modifying the
trailer hitch could reduce the hitch rating.
Do not use a tow hitch that either clamps
on to the bumper or attaches to the axle.
You must distribute the load in your trailer
so that between 10% and 15% of the total
weight of the trailer is on the tongue. Weight Distributing Hitches
A weight distribution hitch is not
recommended for use with your vehicle.
Safety Chains
Always connect the safety chains to the
frame or hook retainers of your vehicle's
tow hitch.
To connect the safety chains, 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.
Note:
Do not attach safety chains to the
bumper.
Trailer Brakes
(If Equipped) 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, manual, automatic or surge-type
trailer brakes are safe if you install them
correctly and adjust them to the
manufacturer's specifications. Trailer
brakes must meet local and federal
regulations.
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
1,500 lb
(680 kg) when loaded.

Integrated Trailer Brake Controller
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. Gain adjustment buttons.
A
Manual control lever.
B
When used correctly, 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 Slide the manual control lever to the left
to turn on the trailer's electric brakes. They
work independently of the tow vehicle's
braking system. See Procedure for
Adjusting the Gain Setting for
instructions on correct 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.
1. Press the + and - buttons to adjust the
brake controller's power output to the
trailer brakes in 0.5 increments. You
can increase the gain setting to 10
(maximum trailer braking) or decrease
it to zero (no trailer braking). Pressing
and holding a button raises or lowers
the setting continuously.
The gain setting displays in the
information display as: Message
Trailer Brake
Gain:
Note: Using the manual control lever
illuminates the trailer's brake lamps and
your vehicle's brake lamps, except the
center high-mounted brake lamp, if you
make the correct electrical connection to

and when adjusting the gain setting. This also displays if you
use the manual control lever or make gain adjustments with
no trailer connected.
Trailer Brake
Gain:
No Trailer
Displays when you press your vehicle's brake pedal, or upon
use of the manual control lever. 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 Brake
Gain:
Output:
Displays when the system senses a correct trailer wiring
connection during a given ignition cycle. For example a trailer
with electric trailer brakes.
Trailer Connected
Displays when the system senses a trailer connection and
then a disconnection, either intentional or unintentional,
during a given ignition cycle, this is accompanied by a single
audible tone. It also displays if a vehicle 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.
Trailer Disconnected
Procedure for Adjusting the Gain Setting
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.
Note: Only carry out this procedure in a
traffic-free environment at speeds of
approximately 20-25 mph (30-40 km/h). 1.
Make sure the trailer brakes are in good
working condition, functioning normally
and correctly adjusted. See a trailer
dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
3. Use the gain adjustment + and -
buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of six is a good
starting point for heavier loads.
4. 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 slide
the manual control lever completely.
242
2021 Transit (TTH) Canada/United States of America, MK3J 19A321 AA enUSA, Edition date: 202010, Second-Printing Towing

5. If the trailer wheels lock, indicated by
squealing tires, reduce the gain setting.
If the trailer wheels turn freely, increase
the gain setting. Repeat steps four and
five until the gain setting is at a point just below trailer wheel lock. If towing
a heavier trailer, trailer wheel lock may
not be attainable even with the
maximum gain setting of 10.
System Warning Messages Action and Description
Message
Displays 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.
Trailer Brake Module
Fault
Displays when there is a short circuit on the electric brake
output wire. If the message displays, accompanied by a single
tone, with no trailer connected, the problem is with your
vehicle wiring between the trailer brake controller and the 7-
pin connector. If the message only displays with a trailer
connected, the problem is with the trailer wiring. Consult a
trailer dealer for assistance. This can be a short to ground,
for example a chaffed wire, short to voltage, for example a
pulled pin on trailer emergency breakaway battery or the
trailer brakes may be drawing too much current.
Wiring Fault on Trailer
Note: An authorized dealer can diagnose the trailer brake controller to determine exactly
which trailer fault has occurred. However, the Ford Warranty does not cover this diagnosis
if the fault is with the trailer.
Points to Remember
• 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
correct 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 instability of trailer or tow vehicle.
