trailer LINCOLN NAVIGATOR 2020 Service Manual

Use the supplied measurement card, a tape
measure and pen to carefully mark the area
where to attach the sticker (supplied in the
back cover pocket of your quick start guide).
Make sure the whole sticker is within the
zone between the two arcs or distance
markers on the diagram, and is also visible
in the rear view camera display.
Step 4: Take Measurements
After you correctly place the sticker on the
trailer, you must take some key
measurements.
Note:
You must take accurate
measurements for the system to operate
properly.
Note: When rounding in inches, round
upward if the measured length is a quarter
inch or greater. Round downward if the
measured length is less than a quarter inch.
For example 12.25 in (31.11 cm) would be
rounded up to 12.50 in (31.75 cm). 12.13 in
(30.8 cm) would be rounded down to 12.00 in
(30.48 cm)
. Note:
When rounding in centimeters, round
to the nearest whole centimeter. If the
measurement is less than
0.2 in (0.5 cm)
round downward. If the measurement is
more than or equal to
0.2 in (0.5 cm) round
upward. For example, 11.9 in (30.3 cm) would
be rounded down to 11.8 in (30 cm). 12.0 in
(30.5 cm) would be rounded up to 12.2 in
(31 cm).
Note: Use consistent metric or imperial units
as required by your country or vehicle.
Record the four key distances (A, B, C, D) as
required by the measurement card. Record
the trailer name for these measurements. Distance A
The horizontal distance from the bumper to
the center of the ball hitch on the trailer.
Distance B
The horizontal distance from the center of
the ball hitch to the center of the sticker.
Distance C
The distance from the rear view camera to
the center of the sticker.

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing TowingE247545

Distance D
The horizontal distance from the bumper to
the center of the trailer axle (single axle
trailers), or the center of the axles (trailers
with dual axles or more).
Note:
If the distance ends in anything less
than one half of an inch, round down to the
current whole inch. If a distance ends in one
half or greater of an inch, round up to the
next whole inch. For example, 12.3 in
(31.12 cm) would be rounded down to 12 in
(30.48 cm). 12.5 in (31.75 cm) would be
rounded up to 13 in (33 cm).
Step 5: Enter Measurements Using the
Information Display
Using the recorded measurements, enter the
required data into the system. Follow the on
screen prompts to enter each of the
measurements taken in step 4. When all four
distances have been entered, a confirmation
display will appear. Check the values are
correct before proceeding, or go back to
change any if required. Step 6: Confirming the Sticker Location
Check the rear view camera display to see
if the sticker is identified by the system and
marked with a red circle.
Confirm that the red circle is correctly located
over the sticker image in the display. The on
screen prompt will ask you to confirm this.
Note:
If the system cannot locate the sticker
try cleaning the camera lens, and also make
sure the sticker is within the green zone as
indicated in step 3.
Calibrating the System
To complete setup, drive your vehicle
straight forward between 4 mph (6 km/h) and
24 mph (39 km/h)
following the on screen
prompt.
Note: Check your measurements to make
sure you measured from the correct points.
Note: If you move the steering wheel during
this procedure, the calibration pauses.
Note: We recommend that you do not do
this at night. A message will be displayed during
calibration and after calibration is complete.
Using Pro Trailer Backup Assist
To use the system press the button and
select the required trailer from the display.
316
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Towing

When the sticker is located, the display
prompts you to shift into reverse (R). The
system turns on. Note:
The system does not function if your
hands are on the steering wheel. Remove
your hands to resume operation.
Follow the screen prompts to steer your
vehicle and trailer.
Note: You may have to drive forward to
straighten the trailer.
Take your hands off the steering wheel and
turn the Pro Trailer Backup Assist control
knob instead. The knob acts as the steering
control for the trailer.
Note: The more you turn the knob, the
sharper the trailer turns. Turn and hold counterclockwise to make the
trailer go left. Turn and hold clockwise to make the trailer
go right.
Note:
Practice maneuvering with the system
in a safe open area first.
Note: Try backing up in a straight line and
then turning the knob slowly in the direction
you want to go.
Note: Quickly turning and releasing the knob
results in a jerky movement of the vehicle. 317
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing TowingE246984 E246992 E246991 E246993

Release the knob when the trailer is moving
in the direction you want. Control the
accelerator and brakes while the system
steers your vehicle automatically to keep the
trailer moving straight back.
Note:
You may have to use the knob to
correct the trailer direction when attempting
to move the trailer straight back under some
conditions.
Note: Your vehicle speed is automatically
limited.
Note: When you release the knob or turn it
to the center position, your vehicle follows
the trailer's path.
Troubleshooting
Note: The system requires a clear view of
the sticker placed on the trailer. You must
keep the camera lens and sticker clean for
the system to operate correctly. Setup
The system is designed to be used with a
wide variety of trailers. However there are
some trailers that do not have a proper
surface and location to mount the sticker.
These trailers are not supported. Attempts
to place the sticker on a surface that does
not meet the sticker placement requirement
listed in Step 3 of the setup instruction or
entering inaccurate measurements to
proceed through setup can result in improper
system function.
Accurate measurements are critical to correct
system function. If you need to check
measurements entered or change them you
can access them through the trailer menus
in the instrument cluster. Choose the option
to change the sticker from the change trailer
settings menu. It is not necessary to remove
the sticker if you are just reviewing or
changing measurements.
The following menu warnings or difficulties
may occur during setup. Tips to resolve them
are listed below.Note:
If you still experience issues with the
system's ability to detect the sticker, see the
information in the next section regarding
sticker lost during system operation.
Measurement A has reached maximum or
minimum value:
• The system is designed to work with
drawbars that have a bumper to hitch ball
center measurement of 4 in (10 cm) to
11 in (28 cm) when installed. Do not
attempt to use drawbars that have a
length outside this range as the system
performance will be degraded and could
cause improper system function.
• Make sure that the measurement being
made is the horizontal distance only from
bumper and the hitch ball center. A
straight line distance that includes any
vertical rise or drop will increase the
measurement and make it inaccurate.
Inaccurate measurements will degrade
system performance and could cause
improper system function. See step 4 of
the setup instruction to review
measurement instructions.
318
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Towing

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.

trailer angle reached warning:
•
The system uses your measurements to
determine sticker position and establish
system limits. Accurate sticker placement
and trailer measurements will provide the
best system performance. If you are
consistently receiving this warning it is
likely there is an issue with sticker
placement or the entered measurements.
Make sure that the sticker is placed
correctly based on steps 3 and the
measurements were made correctly
according to Step 4. The troubleshooting
guide for trailer measurements can also
be reviewed for help in making
measurements.
• To change sticker location or change
trailer measurements, go into the Towing
menu, select trailer options, select
change trailer setting and then select the
change sticker option. •
If the sticker location needs to be
changed, the previous sticker must be
removed and a new sticker needs to be
placed on the trailer. ONLY ONE
STICKER SHOULD BE PLACED ON THE
TRAILER FOR PROPER SYSTEM
FUNCTION.
• 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 consistently shows Stop now take
control of steering warning:
• 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 301).
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: For high altitude operation,
reduce the gross combined weight by
2% per 1,000 ft (300 m) starting at the
1,000 ft (300 m) 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 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.
323
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Towing

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. Maximum Trailer Weight
