•
Placing the sticker on a surface angled
away from the vehicle reduces
performance. Use a drawbar that
positions the trailer level to the ground
when attached to the vehicle. This
typically provides a level surface to
mount the sticker. Place the sticker on
a bracket or other object when no level
surface is available.
• Make sure the entire sticker is on a flat
surface that is completely visible to the
camera. Do not fold the sticker over an
edge on the trailer frame. This can
degrade performance.
• Shadows on the sticker may affect
tracking performance under some
lighting conditions. Moving the sticker
to another location within the allowed
placement area may improve
performance. Use the change sticker
option in the information display menu
if you move the sticker.
• You can change your sticker location
by going into the information display
menu, selecting trailer options,
selecting change trailer settings and
then selecting the change sticker
option. The previous sticker must be
removed. ONLY ONE STICKER
SHOULD BE PLACED ON THE TRAILER
FOR CORRECT SYSTEM FUNCTION. •
The camera system uses the entered
measurements to help locate the
sticker. Inaccurate measurements
reduce the system ’s ability to locate
the sticker. Check the measurements
entered into the system are correct.
Refer to step 4 of setup for instructions
on measurements.
• You can change your measurement by
going into the information display
menu, selecting trailer options,
selecting change trailer setting and
then selecting the change sticker
option. Disregard the prompt to remove
this sticker and continue to the next
step if you only plan to update the
measurements for the current sticker
location.
System does not reverse straight:
• Factors such as the drawbar
connection to the hitch receiver, road
camber, road grade and compliance in
the trailer suspension can influence
how straight the system is able to
reverse your trailer when the knob is
not turned. You can compensate for
the trailer drifting to the right or left by
slowly turning the knob until the trailer
is following your preferred path and
then holding the knob in that position.
If you would like to recalibrate the
system for straight backing, you can do
so with the following procedure.
• Go into the information display menu,
select trailer options, select change
trailer setting and then select the
change sticker option. Your saved
measurements display. Do not change
them but continue to confirm
measurements. Once you confirm the
measurements, the system then
prompts you to perform the calibration
procedure.

•
The trailer is not detected. Once your
vehicle is stopped, additional warnings
indicate the trailer is not detected.
Refer to trailer not detected
troubleshooting tips.
• An internal condition for system
operation was not met which requires
your vehicle to return to manual control
of the steering. Using the system for an
extended period of time can cause the
steering system to heat up and turn off
Pro Trailer Backup Assist steering
control to protect itself. The system
may require a cool down time of up to
30 minutes. Keep the system off and
drive forward at a normal speed or
switch the vehicle off.
TRAILER SWAY CONTROL 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 271).

ESSENTIAL TOWING CHECKS
WARNING: Make sure that the
vertical load on the tow ball is between
the minimum and maximum
recommended weight at all times.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
Follow these guidelines for safe towing:
• Do not tow a trailer until you drive your
vehicle at least
1,000 mi (1,600 km).
• 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.
See
Scheduled Maintenance (page 565).
• 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.
Vehicles with a diesel engine have an
engine braking feature.
See General
Information (page 223).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Some vehicles will have the ability to
modify trailer towing features. See
General Information
(page 110). 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

Remove reducers before inserting the 3
inch drawbar. Insert the drawbar into hitch
receiver.
Put the 5/8 inch hitch pin through pin hole.
Place the cotter pin around the neck of
hitch pin. Weight-distributing Hitches WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper
is higher than 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.
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.

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
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 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:
Shows the current gain setting.
• TBC GAIN = XX.X OUTPUT=/ / / /
/ /
: Displays when braking. The bars
indicate the amount of power going to
the trailer brakes.
• TRAILER CONNECTED:
Displays
when the system senses a correct
trailer wiring connection.
• TRAILER DISCONNECTED: Displays
when the system senses a trailer
disconnection.
Procedure for Setting Trailer Brake
Controller Effort
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
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.
3. When you plug in a trailer with electric or electric-over-hydraulic brakes, a
confirmation message 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.

•
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
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• Do not drive faster than
70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts. •
When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (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
Adaptive Steering and you have
enabled Tow/Haul, the Adaptive
Steering system adjusts the steering
response to match your vehicle ’s load.
The system reduces vehicle sensitivity
to steering inputs at higher vehicle
speeds while it maintains the ease of
parking and maneuverability at low
speeds.
• 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 441).

Note:
You can check four-wheel-down
towing status at any time by opening the
driver's door or turning the ignition to the
accessory or on position. A message
displays in the information display
confirming your vehicle is in neutral tow.
When finished towing with all four wheels
on the ground return the transfer case to
its 2H position:
1. With your vehicle still properly secured
to the tow vehicle, put the ignition in
the on position, but do not start the
engine. If your vehicle has an ignition
key, switch the key to on. If your vehicle
has intelligent access, switch the
vehicle into accessory mode. See
Starting and Stopping the Engine
(page
174).
2. Press and hold the brake pedal.
3. Shift out of neutral (N).
4. Release the brake pedal.
Note: If completed successfully, the
instrument cluster displays 2H and Neutral
Tow Disabled
.
Note: If the indicator light and message do
not display, you must perform the procedure
again from the beginning.
Note: If
Shift Delayed Pull Forward
displays in the instrument cluster, a transfer
case blockage is present. See resolving the
shift delayed pull forward message
instructions after this section.
5. Apply the parking brake and disconnect
the vehicle from the tow vehicle.
6. Release the parking brake, start the engine and shift the transmission to
drive (D) to make sure the transfer
case is out of neutral (N).
7. If the transfer case does not successfully shift out of neutral (N),
set the parking brake until you can have
your vehicle serviced. Resolving the
Shift Delayed Pull Forward
Message
1. Press and hold the brake pedal.
2. Put the transmission into neutral (N),
and then start the engine.
3. With the engine running, shift the transmission to drive (D) and let the
vehicle roll forward, up to
3 ft (1 m).
4. Make sure the instrument cluster displays that neutral tow is disabled.

ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving. •
Drive a heavily loaded vehicle or tow a
trailer.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12 –16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
OFF-ROAD DRIVING
Note: The following off-road driving
information applies to Tremor package
equipped vehicles only.
