Calculating 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
hardware
• Driver weight
• Passenger(s) 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. ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1000 miles (1600
kilometers).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See your scheduled
maintenance information.
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
187
Super Duty (TFA) Towing

Once 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.
Fifth-wheel Trailer Hitch (If Equipped) WARNINGS
The mounting pads in the bed are
specifically designed for certain
fifth-wheel trailer hitches and
gooseneck ball hitches. Do not use these
mounting pads for other purposes. Doing
so could result in vehicle structural
damage, loss of vehicle control, and
personal injury. Contact an authorized
dealer to purchase gooseneck and
fifth-wheel hitches that are compatible
with your vehicle. Towing trailers beyond the maximum
limit of the towing system could
result in vehicle structural damage,
loss of vehicle control and personal injury. The hitch rating listed on the trailer
hitch label is the maximum possible
trailer rating. To find the maximum
trailer weight allowed for your specific
vehicle, consult an authorized dealer or the
RV & Trailer Towing Guide provided by an
authorized dealer. Your vehicle may be equipped with a
fifth-wheel prep package. This package
enables your vehicle to accept certain
fifth-wheel trailer hitches and gooseneck
ball hitches. The fifth-wheel trailer hitch
attaches to the four mounting pads in the
pick-up bed. An optional 7-pin trailer wiring
connector may be in the bed as well. The
gooseneck ball hitch is a separate
mounting pad from the fifth-wheel hitch,
located in the center of the bed. Shorter pick-up boxes, such as the 6½-foot
box on the F-250 and F-350, provide less
clearance between the cab and the
fifth-wheel and gooseneck trailer
compared to longer box pick-ups, such as
an 8-foot box on the F-250 or F-350. When
selecting a trailer and tow vehicle, it is
critical to check that this combination
provides clearance between the front of
the trailer and tow vehicle for turns up to
90 degrees. Failure to follow this
recommendation could result in the trailer
contacting the cab of the tow vehicle
during tight turns that are typical during
low-speed parking and turning maneuvers.
This contact could result in damage to the
trailer and tow vehicle.
Safety Chains
Note:
Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
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.
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.

•
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 time,
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 See the following Procedure for
adjusting gain section 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 CONNECTED
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.
191
Super Duty (TFA) Towing

TRAILER BRAKE MODULE FAULT:
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.
WIRING FAULT ON TRAILER: Displays
when there is a short circuit on the electric
brake output wire. If the
WIRING FAULT
ON TRAILER 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 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.

Super Duty (TFA) Towing

It is acceptable to have your two-wheel
drive vehicle towed with the front wheels
on the ground (without dollies) and the
rear wheels off the ground.
We recommend towing a four-wheel drive
vehicle with all wheels off the ground, such
as using a wheel lift and dollies or flatbed
equipment. However, it is acceptable to
use a wheel lift to raise the rear of your
vehicle so long as, depending on vehicle
configuration, you perform the following
before towing:
•
If your vehicle is equipped with a
manual-shift transfer case, make sure
the front wheel hub locks are in the
FREE position before towing.
• If your vehicle is equipped with an
electronic shift-on-the-fly transfer
case, make sure you turn the
four-wheel drive control to the
2H
position before towing.
Note: Towing an electronic shift-on-the-fly
four-wheel drive vehicle with the front
wheels on the ground without disengaging
the front hubs may cause damage to the
automatic transmission.
Note: Towing a two-wheel drive vehicle or
an electronic shift-on-the-fly four-wheel
drive vehicle with the rear wheels on the
ground for more than 50 miles (80 km) or
faster than 35 mph (56 km/h) may cause
damage to the automatic transmission.
Note: Using wheel lift equipment to tow a
dual rear wheel vehicle requires removing
an outer rear wheel before towing. TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in position
N. If
you cannot move the transmission into
N
, you may need to override it. See
Transmission (page 140).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is 50 miles (80
kilometers).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle. See
Climate Control
(page 102).
Follow these guidelines if you have a need
for recreational towing, such as towing
your vehicle behind a motorhome. We
designed these guidelines to prevent
damage to your transmission.
Two-wheel Drive Vehicles and
Four-wheel Drive Vehicles Equipped
with an Electronic-shift Transfer Case
Do not tow your vehicle with any wheels
on the ground, as vehicle or transmission
damage may occur. It is recommended to
tow your vehicle with all four (4) wheels
off the ground, such as when using a
car-hauling trailer. Otherwise, you cannot
tow your vehicle.

WARNINGS
Never place floor mats or any other
covering on top of already installed
floor mats. Floor mats should always
rest on top of vehicle carpeting surface and
not another floor mat or other covering.
Additional floor mats or any other covering
will reduce the pedal clearance and
potentially interfere with pedal operation. Check attachment of floor mats on
a regular basis. Always properly
reinstall and secure floor mats that
have been removed for cleaning or
replacement. Always make sure that objects
cannot fall into the driver foot well
while the vehicle is moving. Objects
that are loose can become trapped under
the pedals causing a loss of vehicle control. Failure to properly follow floor mat
installation or attachment
instructions can potentially cause
interference with pedal operation causing
loss of control of vehicle. To install floor mats, position the
floor mat so that the eyelet is over
the retention post and press down
to lock in. To remove the floor mat, reverse the
installation procedure.
SNOWPLOWING
Ford recommends that the Super Duty
F-Series used for snow removal includes
the snow plow package option.
Installing the Snowplow
Weight limits and guidelines for selecting
and installing the snowplow can be found
in the Ford Truck Body Builders Layout
Book, snowplow section, found at
www.fleet.ford.com/truckbbas. A typical
installation affects the following: •
Certification to government safety laws
such as occupant protection and airbag
deployment, braking, and lighting. Look
for an Alterer ’s Label on the vehicle
from the snowplow installer certifying
that the installation meets all
applicable Federal Motor Vehicle
Safety Standards (FMVSS).
• The Total Accessory Reserve Capacity
(TARC) is shown on the lower right side
of the vehicle ’s Safety Compliance
Certification Label. This applies to
Ford-completed vehicles of 10,000
pounds (4,536 kilograms) GVWR or
less. This is the weight of
permanently-attached auxiliary
equipment, such as snowplow
frame-mounting hardware, that can
be added to the vehicle and satisfy
Ford compliance certification to
FMVSS. Exceeding this weight may
require the auxiliary equipment installer
additional safety certification
responsibility. The Front Accessory
Reserve Capacity (FARC) is added for
customer convenience.
• Rear ballast weight behind the rear
axle may be required to prevent
exceeding the FGAWR, and provide
front-to-rear weight balance for proper
braking and steering.
• Front wheel toe may require
re-adjustment to prevent premature
uneven tire wear. Specifications are
found in the Ford Workshop Manual.
• Headlight aim may require
re-adjustment.
