Measurement B has reached maximum or
minimum value:
•
Make sure that the sticker placement
instruction in step 3 of the setup has
been followed. Stickers placed outside
the allowed zone will adversely affect the
system performance and could cause
improper feature function.
• Make sure that the measurement being
made is the horizontal distance only from
center of sticker to the hitch ball center.
A straight line distance that includes any
vertical rise or drop will increase the
measurement and cause an inaccurate
value to be entered into the system. See
step 4 of the setup for additional
measurement instructions.
Measurement C has reached maximum or
minimum value:
• Make sure that the sticker placement
instructions in step 3 of the setup have
been followed. Stickers placed outside
the allowed zone will adversely affect the
system performance and could cause
improper feature function. If you have
met all the criteria for sticker placement
and you see this message this sticker is either too far below or too close to the
camera to properly recognize the sticker.
In order for the system to operate
correctly the sticker height must be
lowered if you receive the minimum
warning or the sticker height must be
raised if you receive the maximum
warning.
• Only one sticker can be placed on the
trailer for correct system function. The
previous sticker must be removed or
covered so only one sticker is visible to
the camera.
• Measurement B and C must be measured
again if a new sticker is placed on the
trailer.
Measurement D has reached maximum or
minimum value:
• Make sure that the measurement being
made is the horizontal distance only from
the bumper to the center of the single
axle or the center of all the axles on the
trailer. See step 4 of the setup for
additional measurement instructions. The
TBA system does not support trailer
lengths outside the range allowed by the
information display. System is circling something beside the
sticker or system cannot find the sticker:
•
Make sure the rear camera is clean and
the sticker is clearly visible in the camera
image. Clean the camera and sticker if
necessary.
• The camera system uses the entered
measurements to help locate the sticker.
Inaccurate sticker measurements will
degrade the system ’s ability to locate the
sticker. Verify the measurements entered
into the system are accurate.
• Remove the incorrectly circled label or
decal if possible.
• If you cannot resolve the issue a new
sticker location should be tried. The
sticker location must still meet the
requirements noted in step 3 of the setup
instructions. Only one sticker can be
placed on the trailer for correct system
function. The previous sticker must be
removed or covered so only one sticker
is visible to the camera.

Calibration
The system monitors various vehicle
parameters to ensure your vehicle is being
driven straight and the trailer straight behind
your vehicle. Any steering input or trailer
movement will pause the calibration.
For best results:
•
Use a long, straight, smooth and level
road when attempting to calibrate.
• Drive straight forward.
• Drive between 4 mph (6 km/h) and
24 mph (39 km/h).
System Operation
The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below. The system is not available:
•
The system relies on many sub-systems
in your vehicle to operate correctly. If
those sub-systems are not operating
correctly the system may not be
available.
• Low battery voltage is a condition which
will prevent the system from operating.
Please make sure the battery is correctly
charged if the system is not available.
• You may need to drive your vehicle
straight forward above 25 mph (40 km/h)
before the system is available again.
• If the message still displays take your
vehicle to an authorized dealer for
service.
Sticker lost:
• If the system cannot initially find the
sticker, it may be necessary for you to
change the lighting conditions by moving
the vehicle and trailer or waiting until
conditions change.
• Check for the following if you receive the
lost sticker message while using the
system. •
Stop your vehicle as soon as the
message displays.
• Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.
• Clean the sticker and camera to make
sure they are unobstructed.
• Clean the lens with a soft, lint-free cloth
and water.
• Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the sticker,
and then wipe clean with a soft cloth.
• Remove any items that may be blocking
the view of the sticker. Depending on
your trailer configuration and any
equipment mounted to your trailer it is
possible for the sticker to be blocked
from view of the camera as it rotates on
the hitch ball but not be blocked during
setup. Remove the obstruction if
possible. It will be necessary to remove
the sticker from it’ s current location if the
obstruction cannot be cleared and place
a new sticker that will be visible to the
camera in all positions of the trailer
behind your vehicle.

•
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 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 effect
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 your Towing menu if you move
the sticker. •
You can change your sticker location by
going into the Towing 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 will reduce the
system ’s ability to locate the sticker.
Check the measurements entered into
the system are correct. Refer to the step
4 of Pro trailer backup Assist setup for
instructions on measurements.
• You can change your measurement by
going into the Towing 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 will not backup 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 back your trailer
when the knob is not turned. You can
compensate for the trailer drifting to the
right or left by slowly turning the Pro
Trailer Backup Assist knob until the trailer
is following your desired 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 Towing menu, select trailer
options, select change trailer setting and
then select the change sticker option.
Your saved measurements will be
displayed. Do not change them but
continue to confirm measurements. Once
you confirm the measurements, the
system will then prompt you to perform
the calibration procedure.

• The system displays this warning when
it can no longer steer the vehicle and you
must take over steering. There are four
reasons why this warning displays and
additional information regarding the
reason for the warning is available on the
center display.
• The steering wheel is touched while the
system is controlling it. Avoid touching
the wheel during system operation. •
The maximum speed for feature
operation is exceeded. System
performance is optimized at slower
speeds. Backup slowly.
• The sticker was lost by the camera
system. Once your vehicle is stopped
additional warnings will indicate the
sticker was lost. Refer to sticker lost
trouble shooting tips.
• An internal condition for system
operation was not met which requires
your vehicle return to manual control of
the steering.
Note: The system is designed to be used
with the same trailer connection every time
the trailer is chosen from the selection menu.
Using a different drawbar or a different pin
hole (on drawbars with more than one) when
connecting the drawbar to your vehicle
affects the trailer measurements. Take the
measurements again and update if required.

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 309).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer weight
for your vehicle configuration listed in
the chart below.
Note: Make sure to take into
consideration trailer frontal area. Do not
exceed 55 ft² (5.11 m²) if your vehicle has
the standard towing package, or 60 ft²
(5.57 m²) if your vehicle has the heavy
duty package. 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) of 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 the
vehicle ’s electrical system may not
include the wiring connector needed to
activate electric trailer brakes.

Your vehicle may tow a 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.
To calculate 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.
• Driver weight.
• Passenger weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment weight.
3. This equals the maximum loaded trailer weight for this combination. Note:
The trailer tongue load figures
into the payload for your vehicle.
Reduce the total payload by the final
trailer tongue weight.
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 1,000 mi (1,600 km).
• Consult your local motor vehicle laws for
towing a trailer.
• See any instructions that come with
towing accessories for the proper
installation and adjustment specifications.
• Service your vehicle more frequently if
you tow a trailer.
See Scheduled
Maintenance (page 539).
• If you use a rental trailer, follow the
instructions the rental agency gives you.
You can find information on load
specification terms found on the tire label
and Safety Compliance label as well as
instructions on calculating your vehicle's load
in the Load Carrying chapter. See Load Limit
(page
309).
Remember to account for the trailer tongue
weight as part of your vehicle load when
calculating the total vehicle weight. Trailer Towing Connector (Vehicles
with a Trailer Towing Package and
7–Pin 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. Function

Trailer Hitch Cover
Your vehicle has a removable trailer hitch
cover. To remove the trailer hitch cover:
330
Navigator (TB9) Canada/United States of America, enUSA, First-Printing TowingE163167

1.
Grab the trailer hitch cover at the bottom
and pull towards the rear of the vehicle
until the bottom of the trailer hitch cover
unsnaps from the bumper.
2. Grab the trailer hitch cover at the edge and rotate until the top of the trailer hitch
cover unsnaps from the bumper, then
remove the trailer hitch cover.
To install the trailer hitch cover: 1. Line up the snaps on the trailer hitch
cover to the holes on the bumper and
push forward until it snaps into place.
Hitches WARNING: Do not cut, drill, weld or
modify the trailer hitch. Modifying the trailer
hitch could reduce the hitch rating.
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue. Integrated Hitch Rating WARNING:
Towing trailers beyond
the maximum recommended gross trailer
weight exceeds the limit of your vehicle
and could result in engine damage,
transmission damage, structural damage,
loss of vehicle control, vehicle rollover and
personal injury.
The standard integrated hitch has two ratings
depending on mode of operation:
• Weight-carrying mode requires a draw
bar and hitch ball. The draw bar supports
all the vertical tongue load of the trailer.
• Weight-distributing mode requires an
aftermarket weight-distributing system,
which includes draw bar, hitch ball, spring
bars and snap-up brackets. This system
distributes the vertical tongue load of the
trailer between the truck and the trailer.
You must use a weight-distributing hitch for
weights above 6,000 lb (2,721 kg), up to your
vehicle's maximum towing capacity.
331
Navigator (TB9) Canada/United States of America, enUSA, First-Printing TowingE268259 E268260

Note:
These are hitch ratings only. Actual
vehicle ratings are dependent on engine,
transmission and axle combinations.
Weight-distributing Hitch 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 half the way
down from H2, toward H1.
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.
When 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. Safety Chains
Note:
Do not attach safety chains to the
bumper. Always connect the safety chains
to the frame or hook retainers of your trailer
hitch.
Install trailer safety chains to the trailer hitch
as recommended by the manufacturer. 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. If the trailer safety chain hook has a latch,
make sure the latch fully closes.
