CONNECTING A TRAILER
PRECAUTIONS
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
Normal Scheduled
Maintenance (page 667).
If you use a rental trailer, follow the
instructions the rental agency gives you.
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Account for the trailer coupler weight as
part of your vehicle load when calculating
the total vehicle weight.
Do not exceed the load limits. See
Calculating the Load Limit
(page 415).
HITCHES
HOOKING UP A TRAILER USING A
WEIGHT-DISTRIBUTING HITCH 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.
A weight-distributing hitch helps distribute
tongue load to all towing vehicle and trailer
wheels. For more information, visit the links
in the following table. Website

CONNECTING A TRAILER
Recognizing a Trailer
1. Attach the trailer and wiring connector
to your vehicle.
2. Switch on your vehicle.
3. Set up a profile for the trailer using the
touchscreen.
Note: If your vehicle does not recognize the
trailer, press and hold the brake pedal for a
few seconds.
Note: Trailer profiles store trailer types,
dimensions, preferences, trailer specific
mileage and fuel economy.
Note: Disabling the trailer detection
notification makes the default trailer profile
active when the system detects a
connection.
424
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Connecting 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.

Using Trail Control
Trail Control provides you the ability to
maneuver the vehicle without using the
throttle and brake pedals.
The system controls acceleration and
braking in difficult off-road environments,
which allows you to focus on steering. See
Trail Control (page 324).
Trail Control Performance:
• Manages wheel slip to maximize
traction.
• Provides braking to maximize traction
in descents.
Using Trail One Pedal Drive
(If
Equipped)
Trail one pedal drive allows you to
accelerate and brake using only the
accelerator pedal.
Use this when driving over large obstacles,
such as rocks or logs, to help maintain a
constant vehicle speed.
In 4H, the system offers lift pedal braking
and auto hill hold functionality. See
What
Is Trail One Pedal Drive (page 325).
Note: Trail one pedal drive is only available
when the vehicle is in 4H or 4L.
AFTER DRIVING YOUR VEHICLE
OFF-ROAD - RAPTOR WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death. WARNING:
Always re-inflate tires
to recommended tire pressures before
the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road, check for damage and, if
necessary, have your vehicle repaired by
an authorized dealer.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Check the radiator for mud and debris and
clean as needed.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
After operation in mud, sand, water, or
similar dirty conditions, inspect the
underbody and clean your vehicle.

the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road check for damage to your
vehicle and, if necessary, have your vehicle
fixed as soon as possible.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Check the radiator for mud and debris and
clean as needed.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
After extended operation in mud, sand,
water, or similar dirty conditions, inspect
the underbody and clean your vehicle as
soon as possible.
If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause vibrations
while driving and wheel imbalance.
Remove the material to resolve the
problem.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below approximately
-13°F (-25°C)
. DRIVING ON SNOW AND ICE WARNING:
If you are driving in
slippery conditions that require tire
chains or cables, then it is critical that
you drive cautiously. Keep speeds down,
allow for longer stopping distances and
avoid aggressive steering to reduce the
chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
On ice and snow, you should drive more
slowly than usual. Your vehicle has a four
wheel anti-lock brake system, do not pump
the brake pedal.
See Anti-Lock Braking
System Limitations (page 308).
BREAKING-IN
Your vehicle requires a break-in period. For
the first 1,000 mi (1,600 km), avoid driving
at high speeds, heavy braking, aggressive
shifting or using your vehicle to tow. During
this time, your vehicle may exhibit some
unusual driving characteristics.
DRIVING ECONOMICALLY
The following helps to improve fuel
consumption:
• There is no need to wait for your engine
to warm up. The vehicle is ready to
drive immediately after starting.
• Your fuel consumption should improve
throughout your hybrid's break-in
period.
• Accelerate and slow down in a smooth,
moderate fashion.
476
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Driving Hints

•
Moderate braking is particularly
important since it allows you to
maximize the energy captured by the
regenerative braking system.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Driving on flat terrain.
• Drive at reasonable speeds and
observe posted speed limits.
• Shut all windows when driving at high
speeds.
• Combine errands and minimize
stop-and-go driving.
• Drive with the tonneau cover installed
if your vehicle comes with one.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Perform all scheduled maintenance.
Note: Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode.
Avoid these actions; they reduce your fuel
consumption:
• Revving the engine.
• Aggressive driving increases the
amount of energy required to move
your vehicle.
• Driving in lower temperatures during
the first 5–10 mi (12 –16 km) of driving.
• Idle for periods longer than one minute.
• Use the air conditioner or front
defroster. •
Adding certain accessories to your
vehicle like bug deflectors, rollbars,
light bars, running boards, ski racks or
luggage racks.
• Use the speed control in hilly terrain.
• Using fuel blended with alcohol.
• Drive a heavily loaded vehicle or tow a
trailer.
• Driving with the wheels out of
alignment.
DRIVING IN SPECIAL
CONDITIONS
EMERGENCY MANEUVERS
In an unavoidable emergency where you
must make a sudden sharp maneuver, turn
the steering wheel only as rapidly and as
far as required to avoid the emergency.
Apply smooth pressure to the accelerator
pedal or brake pedal as needed. Avoid
abrupt steering, acceleration and braking
changes. Abrupt changes could increase
the risk of vehicle roll over, loss of vehicle
control and personal injury. If possible, use
any available road surfaces to bring your
vehicle under control.
FLOOR MATS WARNING:
Use a floor mat
designed to fit the footwell of your
vehicle that does not obstruct the pedal
area. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Pedals that cannot
move freely can cause loss of vehicle
control and increase the risk of serious
personal injury.
