2018 FORD F-550 axle

Use the supplied measurement card, a
tape measure and pen to carefully mark
the area where to attach the sticker. The
sticker is supplied in the back cover pocket
of your quick start guide. Make sure the
entire sticker is within the gray zone
between the two arcs or distance markers
on the diagram, and is also visible in the
rear view camera display. It should be
between 7
– 20 in (17 –51 cm) from the
trailer ball hitch.
Once you have found the correct location,
place the sticker.
Step 4: Take Measurements
After you place the sticker on the trailer
you must take some measurements.
Note: You must take accurate
measurements for the system to operate
properly.
Note: Round measurement figures to the
nearest half inch.
Note: Round upward if the measured length
is a quarter inch or greater. Round
downward if the measure 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: Use consistent metric or imperial
units as required by your country or vehicle.
The measurement card requires you to
record four key distances (A, B, C, D).
Record the trailer name for these
measurements. Distance A
The horizontal distance from the license
plate 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.
Distance D
The distance from the tailgate to the
center of the trailer axle (single axle
trailers), or the center of the axles (trailers
with dual axles or more).

The following menu warnings or difficulties
may occur during setup. Tips to resolve
them are listed below.
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
9–16 in (229–406 mm) when installed.
Do not attempt to use drawbars that
have a length outside this range as
system performance degrades 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 the
measurement instructions.
Measurement B has reached maximum or
minimum value:
• Make sure you follow the sticker
placement instruction in step 3 of the
setup. Stickers placed outside the
allowed zone 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 correctly operate, 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.

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 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 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.
For additional information on
trailer weights, reference the RV
& Trailer Towing Guide available
at your authorized dealer, or
online. RV & Trailer Towing Guide Online

The active guidelines fade in and out
depending on the steering wheel position.
The active guidelines are not shown when
the steering wheel position is straight.
Always use caution while reversing.
Objects in the red zone are closest to your
vehicle and objects in the green zone are
farther away. Objects are getting closer to
your vehicle as they move from the green
zone to the yellow or red zones. Use the
side view mirrors and rear view mirror to
get better coverage on both sides and rear
of your vehicle.
Refer to the Rear View Camera section for
additional information. See Rear View
Camera (page 236).
Hitches
Note: On pick-up trucks, the trailer hitch
provided on this vehicle enhances crash
protection for the fuel system. Do not
remove!
Note: Do not cut, drill, weld or modify trailer
hitches. Modifying trailer hitches can reduce
hitch rating.
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% for conventional towing or
15-25% for fifth wheel towing of the total
weight of the trailer is on the tongue.
Hitch Components (If Equipped)
The following components are required.
Some are provided in certain vehicles.
• A trailer hitch with a 3 inch receiver and
5/8 inch hitch pin rated to tow up to
21,000 lb (9,525 kg)
.
• A hitch pin sleeve stored in the glove
box to be used when mounting the 3
inch drawbar.
• A cotter pin to help keep the hitch pin
in place. Installing a 3 Inch Drawbar with 3/4
Inch Pin Hole
The pin sleeve should be inserted in the
3/4 inch pin hole of the 3 inch drawbar.
Remove reducers before inserting the 3
inch drawbar. Insert the drawbar into hitch
receiver.

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).
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Your vehicle may be equipped with a
temporary or conventional spare tire. A
"temporary" spare tire is different in size
(diameter or width), tread-type
(All-Season or All Terrain) or is from a
different manufacturer than the road tires
on your vehicle. Consult information on the
tire label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
you remove the trailer from the water.
294
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Towing

When backing down a ramp during boat
launching or retrieval:
•
Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than 6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
•
Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in neutral (N).
If you cannot move the transmission
into neutral (N), you may need to
override it. See
Transmission (page
208).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km). WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. Recreational Towing
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle. See
Climate Control
(page 146).
Follow these guidelines if you have a need
for recreational towing, such as towing
your vehicle behind a motorhome. We have
designed these guidelines to prevent
damage to your transmission.
Two-wheel Drive Vehicles
Do not tow your vehicle with any wheels
on the ground, as vehicle or transmission
damage may occur. It is recommended to
tow your vehicle with all four (4) wheels
off the ground, such as when using a
car-hauling trailer. Otherwise, you cannot
tow your vehicle.
