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 (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 265).
RECOMMENDED TOWING
WEIGHTS WARNING:
You must use
the heavy-duty drawbar pin
supplied with your vehicle when
using the heavy-duty hitch.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death.
Note: Vehicles with a
21,200 lb
(9,616 kg) hitch and above must
use the drawbar pin that came with
the vehicle. You can obtain a
replacement drawbar pin at your
authorized dealer.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 60 ft² (5.6 m²)
trailer frontal area for conventional
trailers. Do not exceed 75 ft² (6.9
m²) trailer frontal area for fifth
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: Your vehicle could have
reduced performance when
operating at high altitudes and
when heavily loaded or towing a
trailer. When driving at elevation,
in order to match driving
performance as perceived at sea
level, reduce gross vehicle weight
and gross combination weight by
2% per 1,000 ft (300 m) elevation. 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
calculated using the formula
following the chart. Pickup and box delete

ESSENTIAL TOWING CHECKS
WARNING: Do not exceed the
maximum vertical load on the tow ball.
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 553).
• 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 217).
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 109). 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.

•
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 429).

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.

•
Inspect exhaust system for damage or
looseness.
• Inspect undercarriage fasteners. If any
are loose or damaged, tighten or
replace ensuring that the proper torque
specification is used.
• Inspect the tires for any cuts in the
tread or sidewall area. Also inspect the
sidewall for any bulge indicating
damage to the tire.
• Inspect the wheels for dents, cracks,
or other damage.
• Refit the front license plate if removed
previously.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications
(page
437).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle. Note:
Engine damage can occur if water
enters the air filter.
For Vehicles without Tremor Off-
Road Package
Note: Driving through standing water can
cause vehicle damage.
Note: Drive through water in an emergency
only and not as part of normal driving.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
