PARKING BRAKE
WARNING
Always set the parking brake fully
and make sure the transmission is
placed in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. Turn the ignition to the lock
position and remove the key whenever you
leave your vehicle. Apply the parking brake whenever your
vehicle is parked. Press the pedal
downward to set the parking brake. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release, pull the brake release lever
located at the lower left side of the
instrument panel.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake. Failure to leave your vehicle securely
parked may lead to a crash or injury. See
Parking Brake (page 168). WARNINGS
You must remain in your vehicle
when the system turns on. At all
times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death. The system will turn off if a
malfunction is apparent or if you rev
the engine excessively. Failure to
take care may result in the loss of control
of your vehicle, serious personal injury or
death. The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient torque to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space.
Note:
The system only functions when you
bring your vehicle to a complete standstill
in an uphill gear (for example, drive (D)
when facing uphill or reverse (R) when
facing downhill).
Note: There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed.

PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot control
descent in all surface conditions and
circumstances, such as ice or
extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of vehicle
control, crash or serious injury. Hill descent control does not provide
hill hold at zero miles per hour (0
kilometers per hour). When stopped,
the parking brake must be applied or the
vehicle must be placed in P (Park) or it
may roll away. Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system will provide a
warning in the message center and a chime
will sound when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button located on the
instrument panel. A light in the
cluster will illuminate and a chime will
sound when this feature is activated.
To increase descent speed, press the
accelerator pedal until the desired speed
is reached. To decrease descent speed,
press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once
the desired descent speed is reached,
remove your feet from the pedals and the
chosen vehicle speed will be maintained.
Note: Noise from the ABS pump motor may
be observed during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill descent modes
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and Hill Descent Control is
active, the Hill Descent Control telltale
will flash.
• At speeds below 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed and conditions are not
correct for hill descent activation, the
Hill Descent Control system will be
enabled, the Hill Descent Control
telltale will be solid and a message will
display in the information display.
• At speeds above 20 mph (32 km/h):
When the Hill Descent Control switch
is pressed, the Hill Descent Control
system will be enabled, the telltale in
the cluster will not be illuminated and
a message will be displayed in the
information display.

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 Fuses
(page 223).
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. 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
183).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

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 183). RECOMMENDED TOWING
WEIGHTS
Note:
Make sure to take into
consideration trailer frontal area.
Do not exceed 60 feet 2
(5.6
meters 2
) trailer frontal area for
conventional trailers. Do not
exceed 75 feet 2
(6.9 meters 2
) trailer
frontal area for 5th wheel and
gooseneck trailers.
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.

•
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.
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.

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.
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) WARNING
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. 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.

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.
B:
Manual control lever: Slide the control
lever to the left to switch on the trailer's
electric brakes independent of the tow
vehicle's. See the following Procedure for

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 lights both the trailer brake lamps
and your vehicle brake lamps.
Trailer brake control messages appear in
the information display as follows:
• TBC GAIN = XX.X NO TRAILER:

disconnection.
Procedure for Setting Trailer Brake
Controller Effort
See
General Information (page 88). Choose either the electric option for trailers
with electromagnetic drum brakes, or the
electric over hydraulic option for trailers
with these brake systems.
Trailer Brake Effort Setting
The trailer brake controller allows the user
to customize how aggressively the trailer
brakes engage. The default value is the low
setting and is the recommended setting
for most trailers. If your trailer's brakes
require more initial voltage, or if you prefer
more aggressive trailer braking, then select
either the medium or the high setting.
Procedure for Setting Trailer Brake
Controller Mode
See
General Information (page 88).
Choose the low, medium or high setting
for the required initial trailer brake output.
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 adjusts 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.

Super Duty (TFA) Canada/United States of America, enUSA, Second Printing Towing

•
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.
• When you switch the engine off, the
controller output is disabled and the
display and module shut down.
Trailer Lamps WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required. Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts. •
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed while towing may reduce
this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant (if the axle is not already
filled with it). See
Capacities and
Specifications (page 303).
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
