The controller user interface consists of
the following:
A: + and - (Gain adjustment buttons):
Pressing these buttons adjusts the
controller's power output to the trailer
brakes in 0.5 increments. You can increase
the gain setting to 10.0 (maximum trailer
braking) or decrease it to 0 (no trailer
braking). The gain setting displays in the
message center.
The controller shows gain setting, output
bar graph, and trailer connectivity status
in the information display. They appear in
the information display as follows:
• Trailer Brake Controller Gain (without
trailer connected): Shows the current
gain setting during a given ignition cycle
and when adjusting the gain. This also
displays if you use the manual control
lever or make gain adjustments with
no trailer connected.
• Trailer Brake Controller Gain Output:
Displays when you push your vehicle's
brake pedal, or upon use of the manual
control. Bar indicators illuminate in the
information display to indicate the
amount of power going to the trailer
brakes relative to the brake pedal or
manual control input. One bar indicates
the least amount of output; six bars
indicate maximum output.
• Trailer Connected: Displays when the
system senses a correct trailer wiring
connection (a trailer with electric trailer
brakes) during a given ignition cycle.
• Trailer Disconnected: Displays,
accompanied by a single audible time,
when the system senses a trailer
connection and then a disconnection,
either intentional or unintentional,
during a given ignition cycle. It also
displays if a truck or trailer-wiring fault
occurs causing the trailer to appear
disconnected. This message can also
display if you use the manual control lever without a trailer connected. After
disconnecting the trailer connector,
press the brake pedal for
approximately five seconds to allow
the system to detect and update the
trailer status.
B:
Manual control lever: Slide the control
lever to the left to turn on the trailer's
electric brakes independent of the tow
vehicle's. See the following Procedure for
adjusting gain section for instructions on
proper use of this feature. If you use the
manual control while the brake is also
applied, the greater of the two inputs
determines the power sent to the trailer
brakes.
• Stop lamps: Using the manual control
lever illuminates both the trailer brake
lamps and your vehicle brake lamps
except the center high-mount stop
lamp, if you make the proper electrical
connection to the trailer. Pressing your
vehicle brake pedal also illuminates
both trailer and vehicle brake lamps.
Procedure for Setting Trailer Brake
Controller Mode
Select the correct option using the
information display. Choose electric for
trailers with electromagnetic drum brakes
or EOH for trailers with electric over
hydraulic brake systems. See Information
Displays
(page 120).
Trailer Brake Effort Setting
The trailer brake controller allows the user
to customize how aggressively the trailer
brakes engage. The default value is "Low"
and is the recommended setting for most
trailers. If your trailer's brakes require more
initial voltage, or if you prefer more
aggressive trailer braking, then select either
the "Medium" or the "High" setting.

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
217).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle. See
Climate Control
(page 151).
Follow these guidelines if you have a need
for recreational towing, such as towing
your vehicle behind a motorhome. These
guidelines are designed to prevent damage
to your transmission.
Two-wheel Drive Vehicles
You cannot tow a two-wheel drive vehicle
with any wheels on the ground as vehicle
or transmission damage may occur. You
must tow your vehicle with all four wheels
off the ground, such as when using a
car-hauling trailer.

ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving. •
Drive a heavily loaded vehicle or tow a
trailer.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12 –16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
OFF-ROAD DRIVING
In addition to providing an excellent
on-road driving experience, your vehicle
excels at all types of off-road driving. The
truck has been designed and equipped to
allow you to explore those places where
the road doesn ’t take you whether it’ s a

Snowplow Mode (If Equipped)
Press the snowplow button on the
instrument panel to switch on snowplow
mode. The button illuminates when in
snowplow mode. A message appears in
the information display indicating that
features are turned off when in snowplow
mode.
The following features are disabled when
in snowplow mode:
• 110V inverter.
• Fog lamps.
• Heated steering wheel.
• Heated front and rear seats.
• Massaging seats.
The body module also activates the
snowplow relay that provides power to
aftermarket snowplow controls.
Switch off snowplow mode by pressing
the snowplow button or switching off the
ignition. The snowplow button is no longer
illuminated and features are turned on.
Note: The electrical system is designed to
support the addition of a residential
snowplow (up to 60 Amps continuous) and
snowplow lights (up to 20 Amps
continuous) using snowplow mode. The
system is not designed to support snowplow
usage with additional electrical aftermarket
accessories.
Operating the Vehicle with the
Snowplow Attached
Note: Drive the vehicle at least
500 mi
(800 km) before using your vehicle for snow
removal.
We recommend vehicle speed does not
exceed
45 mph (72 km/h) when
snowplowing. The attached snowplow blade restricts
airflow to the radiator, and may cause the
engine to run at a higher temperature.
Attention to engine temperature is
especially important when outside
temperatures are above freezing. Angle
the blade to maximize airflow to the
radiator and monitor engine temperature
to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in your
Scheduled Maintenance information for
engine oil and transmission fluid change
intervals.
Snowplowing with your Airbag
Equipped Vehicle
WARNING:
Do not attempt to
service, repair, or modify the airbag
supplemental restraint systems or its
fuses on a vehicle containing air bags as
you could be seriously injured or killed.
Contact your authorized dealer as soon
as possible. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Modifying or adding
equipment to the front end of your
vehicle (including hood, bumper system,
frame, front end body structure, tow
hooks and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not
modify or add equipment to the front
end of your vehicle.

Note:
Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See
Capacities and Specifications (page
424).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage.
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as possible. Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Note: Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.

F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Maintenance

Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management (If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display. You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no
need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after
several minutes, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.

GENERAL INFORMATION
Notice to utility vehicle and truck
owners
WARNING: Utility vehicles have a
significantly higher rollover rate than
other types of vehicles. WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Utility vehicles and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles and trucks are not
designed for cornering at speeds as high
as passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions. Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to
reduce the risk of an accident or serious
injury.
Four-wheel drive system (if
equipped)
A vehicle equipped with four-wheel drive
(when selected) has the ability to use all
four wheels to power itself. This increases
traction which may enable you to safely
drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
On some four-wheel drive models, the
initial shift from two-wheel drive to
four-wheel drive while the vehicle is
moving can cause a momentary clunk and
ratcheting sound. These sounds are normal
as the front drivetrain comes up to speed
and are not cause for concern.
Note:
In four-wheel drive vehicles, the size
of the spare tire relative to the remaining
tires can have an effect on the 4x4 system.
If there is a significant difference between
the size of a spare and the remaining tires,
four-wheel drive functionality may be
limited. See Using Four-Wheel Drive (page
223
).
How your vehicle differs from
other vehicles
Sport utility vehicles and trucks can differ
from some other vehicles in a few
noticeable ways. Your vehicle may be:
391
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Wheels and Tires

WARNING: Always inflate
steel carcass tires with a remote
air fill with the person inflating
standing at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
The two front tires or two rear tires
should generally be replaced as a
pair, except if the vehicle is
equipped with four wheel drive.
Vehicles equipped with four wheel
drive should have all four tires
replaced simultaneously.
Unevenly worn tires, mismatched
makes, models or brands can be
different in size, resulting in
potential damage to the four
wheel drive system.
The tire pressure sensors mounted
in the wheels are not designed to
be used in aftermarket wheels.
The use of wheels or tires not
recommended by us may affect
the operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged. Safety Practices WARNING:
If your vehicle
is stuck in snow, mud or sand, do
not rapidly spin the tires;
spinning the tires can tear the
tire and cause an explosion. A
tire can explode in as little as
three to five seconds. WARNING:
Do not spin the
wheels at over 34 mph
(55 km/h). The tires may fail and
injure a passenger or bystander.
Driving habits have a great deal
to do with your tire mileage and
safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on
the road
*Do not run over curbs or hit the
tire against a curb when parking
Highway Hazards
No matter how carefully you drive
there ’s always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
