PARKING AID (IF EQUIPPED)
WARNINGS
To help avoid personal injury, please
read and understand the limitations
of the system as contained in this
section. Sensing is only an aid for some
(generally large and fixed) objects when
moving in reverse on a flat surface at
parking speeds. Traffic control systems,
inclement weather, air brakes, and external
motors and fans may also affect the
function of the sensing system; this may
include reduced performance or a false
activation. To help avoid personal injury, always
use caution when in R (Reverse) and
when using the sensing system.
This system is not designed to
prevent contact with small or moving
objects. The system is designed to
provide a warning to assist the driver in
detecting large stationary objects to avoid
damaging the vehicle. The system may not
detect smaller objects, particularly those
close to the ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the
normal detection zone of the system, may
create false beeps. Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
If your vehicle is equipped with
MyKey ™, it is possible to prevent turning
the sensing system off. See MyKey ™
(page
50).
Note: If your vehicle is equipped with a fully
integrated electronic trailer brake controller
(TBC) and a trailer with electric trailer
brakes is connected to your vehicle, the RSS
will be disabled. When the vehicle is shifted
into reverse, the information display will
remain in the Rear Park Aid Off selection.
For more information on the TBC, See
Trailer Sway Control
(page 188).
The sensing system warns the driver of
obstacles within a certain range of the
bumper area. The system turns on
automatically whenever the ignition is
switched on.
When receiving a detection warning, the
radio volume is reduced to a
predetermined level. After the warning
goes away, the radio volume returns to the
previous level.
Rear Sensing System
The rear sensors are only active when the
transmission is in R (Reverse). As the
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is fewer than 12 inches
(30 centimeters) away, the warning
sounds continuously. If a stationary or
receding object is detected farther than 12
inches (30 centimeters) from the side of
the vehicle, the tone sounds for only three
seconds. Once the system detects an
object approaching, the warning sounds
again.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal.
USING CRUISE CONTROL
WARNINGS
Do not use cruise control in heavy
traffic, on winding roads or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed may increase above
the set speed. The system will not
apply the brakes. Change down a gear to
assist the system in maintaining the set
speed. Failure to do so could result in loss
of vehicle control, serious injury or death. Note:
Cruise control will disengage if the
vehicle speed decreases more than 10 mph
(16 km/h) below your set speed while
driving uphill. The cruise controls are located on the
steering wheel.
Switching Cruise Control On

for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight - is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10– 15% (conventional trailer) or
king pin weight of 15– 25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an authorized dealer) for more
detailed information.
Tongue Load or Fifth Wheel
King Pin Weight -
refers to the
amount of the weight that a trailer
pushes down on a trailer hitch. Examples:
For a 5000 pound
(2268 kilogram) conventional
trailer, multiply 5000 by 0.10 and
0.15 to obtain a proper tongue
load range of 500 to 750 pounds
(227 to 340 kilograms). For an
11500 pound (5216 kilogram) fifth
wheel trailer, multiply by 0.15 and
0.25 to obtain a proper king pin
load range of 1725 to 2875 pounds
(782 to 1304 kilograms). WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label. Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower the
vehicle ’s GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations. Exceeding any vehicle weight
rating limitation could result
in serious damage to the vehicle
and/or personal injury. Steps for determining the
correct load limit:
1. Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle ’s placard.
181
Super Duty (TFA) Load Carrying

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See the Fuses
chapter.
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
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 tow bar with the
correct rise or drop. 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
176). You can also find the
information in the RV & Trailer
Towing Guide, available at an
authorized dealer.

TRAILER SWAY CONTROL (IF
EQUIPPED) 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.
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
Load
Carrying (page 176).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed a trailer
weight of 5000 pounds (2268
kilograms) when towing with, or
by, bumper only. Note:
Make sure to take into
consideration trailer frontal area.
Do not exceed 60 feet 2
(5.6
meters 2
) 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 1000 feet (300 meters)
starting at the 1000 foot (300
meter) 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 class I, II,
III and IV trailer or fifth-wheel
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.
188
Super Duty (TFA) Towing

Trailer Towing Connector
When attaching the trailer wiring connector
to your vehicle, only use a proper 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 proper wiring
connector and works correctly with your
vehicle.

Hitches WARNING
On pick-up trucks, the trailer hitch
provided on this vehicle enhances
crash protection for the fuel system.
Do not remove! Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% for conventional towing or
15-25% for fifth wheel towing of the total
weight of the trailer is on the tongue.
Weight-distributing Hitches
WARNING
Do not adjust a weight-distributing
hitch to any position where the rear
bumper of the vehicle is higher than
it was 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
halfway between H1 and H2.
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.
190
Super Duty (TFA) TowingE163167

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.
191
Super Duty (TFA) Towing

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 trailer brake controller has
been verified to be compatible with
trailers having electric-actuated
drum brakes (one to four axles) and some
electric-over-hydraulic 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). Pressing and holding a button
raises or lowers the setting continuously.
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 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 upon use of
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 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.
193
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.
