TOWING A TRAILER
PRECAUTIONS
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. 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. WARNING:
Do not exceed
the lowest rating capacity for
your vehicle or trailer hitch.
Overloading your vehicle or
trailer hitch can impair your
vehicle stability and handling.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death. WARNING: Make sure that
the vertical load on the tow ball
is between the minimum and
maximum recommended weight
at all times. Failure to follow this
instruction could result in the
loss of control of your vehicle,
personal injury or death. WARNING:
Do not cut,
drill, weld or modify the trailer
hitch. Modifying the trailer hitch
could reduce the hitch rating. WARNING:
The anti-lock
brake system does not control
the trailer brakes.
TRAILER BRAKE
PRECAUTIONS WARNING:
Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase. WARNING:
Do not tow a trailer
fitted with electric trailer brakes unless
your vehicle is fitted with a compatible
aftermarket electronic trailer brake
controller. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. For additional information and
assistance, we recommend that you
contact an authorized dealer.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
428
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Towing a Trailer

Certain states require functioning trailer
brakes for trailers over a specified weight.
Be sure to check state regulations for this
specified weight.
Ford Motor Company recommends
separate functioning brake systems for
trailers weighing more than 1,500 lb
(680 kg) when loaded.
TOWING A TRAILER
LIMITATIONS
The vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Note: Your vehicle could have
reduced performance when
operating at high altitudes and
when heavily loaded or towing a
trailer. When driving at elevation,
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.
LOADING YOUR TRAILER
To help minimize how trailer
movement affects your vehicle
when driving:
• Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires. •
Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight. The
trailer tongue weight should
never exceed 10% of the
maximum towing capacity.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
TRAILER TOWING HINTS
Towing a trailer places an extra load on
your vehicle's engine, transmission, axle,
brakes, tires and suspension. Periodically
inspect these components during and after
any towing operation.
When driving with a trailer or payload, a
slight takeoff vibration or shudder may be
present due to the increased payload
weight.
Your vehicle may have a temporary or
conventional spare tire. A temporary spare
tire is different in diameter or width,
tread-type, 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.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Towing a Trailer

When towing a trailer:
•
Obey country specific regulations for
towing a trailer.
• Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission 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 when you are
towing on long, steep slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not continuously
apply the brakes, as they may overheat
and become less effective.
• If your transmission has Grade Assist
or Tow/Haul, use this feature when
towing. This provides engine braking
and helps eliminate excessive
transmission shifting for optimum fuel
economy and transmission cooling.
• Your vehicle has AdvanceTrac with roll
stability control. When towing a trailer,
additional loads could cause the
AdvanceTrac system to engage during
cornering maneuvers. Reduce cornering
speeds to make sure that you can
maintain control of the vehicle and
trailer if the AdvanceTrac system
engages. •
Allow more distance for stopping with
a trailer attached. Anticipate stops and
gradually brake.
• Avoid parking on a slope. However, if
you must park on a slope, turn the
steering wheel to point your vehicle
tires away from traffic flow, set the
parking brake, place the transmission
in park (P) and place wheel chocks in
front and back of the trailer wheels.
Note: Chocks are not included with your
vehicle.
LAUNCHING OR RETRIEVING
A BOAT OR PERSONAL
WATERCRAFT
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
6 in (15 cm) could allow water
to enter vehicle components, causing
internal damage to the components and
affecting driveability, emissions and
reliability.
Note: Replace the rear axle lubricant
anytime the rear axle has been submerged
in water.
Note: Disconnect the trailer wiring
connector before backing the trailer into the
water.
Note: Reconnect the trailer wiring
connector after removing the trailer from
the water.

Positioning the Trailer
Hitch the trailer to your vehicle and
connect the electrical wiring harness.
Check to make sure that the wiring is
working. See Connecting a Trailer (page
424).
Park your vehicle and hitched trailer on a
level surface.
For best results, make sure that your trailer
rides level with the ground when you hitch
your vehicle. See
Connecting a Trailer
(page 424). Make sure that the trailer and your vehicle
are in line with each other. You can do this
by putting the transmission in drive (D) and
pulling straight forward.
Configuring the Trailer in the
Touchscreen
1. Press the button to switch the system
on.
2. Press
Add Trailer on the touchscreen.
3. Follow the directions on the touchscreen to enter the trailer name
and trailer type, then proceed to the
sticker or sensor setup.
Note: If you configure the trailer and install
a sensor, the trailer is saved with that sensor
information. If you want to use this trailer
with the sticker, you need to delete the
trailer from the system and repeat the setup
process.
