2020 FORD F-450 wheel

•
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

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

Note:
If your vehicle is equipped with a
factory brake controller, the Battery (+)
Orange wire is powered when you start the
engine and you apply the brakes at least
once when a trailer with brake lamps is
connected. If your vehicle is not equipped
with a factory brake controller, relays control
the system and it becomes active when you
power on your vehicle.
Dynamic Hitching Using the Rear
View Camera System
Note: Active guidelines and fixed guidelines
are only available when the transmission is
in reverse (R).

you in setting your steering wheel properly
to help align the trailer hitch and tongue. Active guidelines.

To use active guidelines, turn the steering
wheel to point the guidelines toward an
intended path. If the steering wheel
position is changed while reversing, your
vehicle might deviate from the original
intended path.

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 229).
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
a 5/8 inch hitch pin. Check the
stamped rating number on the pin to
determine the
21,200 lb (9,616 kg) or
24,200 lb (10,976 kg) hitch pin
capacity.
• A hitch pin sleeve stored in the glove
box to use when mounting the 3 inch
drawbar with the 3/4 inch pin hole.
• 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.
297
Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- TowingE247903

Remove reducers before inserting the 3
inch drawbar. Insert the drawbar into hitch
receiver.
Put the 5/8 inch hitch pin through pin hole.
Place the cotter pin around the neck of
hitch pin. 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
halfway between H1 and H2.
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.
