trailer FORD F-150 2019 Service Manual

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 license plate to
hitch ball center measurement of 9 in
(23 cm) to 16 in (41 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 license plate and the hitch ball
center. A straight line distance that
includes any vertical rise or drop
increases the measurement and makes
it inaccurate. Inaccurate
measurements degrade system
performance and could cause improper
system function. See step 4 of the
setup instruction to review
measurement instructions.
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
increases the measurement and
causes 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 you follow the sticker
placement instructions in step 3 of the
setup. Stickers placed outside the
allowed zone 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,
the 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 tailgate 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 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 degrade the system ’s
ability to locate the sticker. Verify the
measurements you enter into the
system are accurate.
• Remove the incorrectly circled label or
decal if possible.
• If you cannot resolve the issue, try a
new sticker location. 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 is straight
behind your vehicle. Any steering input or
trailer movement pauses the calibration.
For best results:
• Use a long, straight, smooth and level
road when attempting to calibrate.
• Drive straight forward.
• Drive between 4–24 mph
(6– 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 prevents 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 continues to display,
see your 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 may be
necessary to remove the sticker from
its current location if the obstruction
cannot be cleared. Place a new sticker
that is 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 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 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 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 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 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 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
under system control. Avoid touching
the wheel during system operation.
• The maximum speed for feature
operation is exceeded. System
performance is optimized at slower
speeds. Reverse slowly.
• The sticker was lost by the camera
system. Once your vehicle is stopped,
additional warnings indicate the sticker
was lost. Refer to sticker lost
troubleshooting 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. When using a different drawbar or a
different pin hole on drawbars with more
than one, connecting the drawbar to your
vehicle affects the trailer measurements.
Take the measurements again and update
if required.

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 276).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed a trailer
weight of 5,000 lb (2,268 kg) when
towing with, or by, the bumper only. Note:
For vehicles equipped with
2.7L and 3.3L engines without a
Heavy Duty Towing Package, do
not exceed a trailer weight of
5,000 lb (2,268 kg) when using the
trailer hitch.
Note: For vehicles equipped with
3.5L and 5.0L engines without a
Heavy Duty Towing Package, do
not exceed a trailer weight of
7,000 lb (3,175 kg)
when using the
trailer hitch.
Note: Make sure to take into
consideration trailer frontal area.
Vehicles not equipped with the
Trailer Tow Package or the Heavy
Duty Payload Package should not
exceed 11 ft² (3.4 m²) trailer frontal
area. Vehicles equipped with the
Trailer Tow Package or the Heavy
Duty Payload Package should not
exceed 18 ft² (5.6 m²) trailer
frontal area. All values calculated
with SAE J2807 method.
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.

Calculating 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
previous charts.
2. Subtract all of the following
that apply to your vehicle:
• Vehicle curb weight.
• Hitch hardware weight, for
example a draw bar, ball, locks
or weight distributing hardware.
• Driver weight.
• Passenger(s) weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment weight.
This equals the maximum loaded
trailer weight for this combination.
Note: The trailer tongue load is
considered part of the payload for
your vehicle. Reduce the total
payload by the final trailer tongue
weight.
Note: 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 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 562).
• 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. See Load Limit (page 277).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.

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.

Recognizing a Trailer
1. Attach the trailer and wiring connector
to your vehicle.
2. Switch on your vehicle.
3. Press the brake pedal for a few seconds.
A confirmation message appears in the
information display. See General
Information (page 116).
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the tongue. 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
a quarter 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.
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.
