System Errors
If the system detects a fault, a warning
lamp illuminates and a message displays.
See Information Messages (page 132).
Switching the System On and Off
You can switch the system off using the
information display.
See General
Information (page 120). When you switch
the system off, a warning lamp illuminates
and a message displays. When you switch
the system on or off, the alert indicators
flash twice.
Note: The system remembers the last
setting when you start your vehicle.
Note: The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
To permanently switch the system off,
contact an authorized dealer. CROSS TRAFFIC ALERT
(IF
EQUIPPED) WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The
cross traffic alert system is not a
replacement for careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash.
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases
when the sensors are partially, mostly or
fully obstructed. Slowly reversing helps
increase the coverage area and
effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of
reverse (R).

F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Driving AidsE142440 E142441

Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
Cross Traffic Alert System Sensors
The sensors are behind the rear bumper
on both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Blocked sensors could affect system
performance.
If the sensors are blocked, a message may
appear in the information display when
you shift into reverse (R).
Cross Traffic Alert System
Limitations
The system may not correctly operate
when any of the following occur:
• The sensors are blocked.
• Adjacently parked vehicles or objects
are obstructing the sensors.
• Vehicles approach at speeds less than
4 mph (6 km/h) or greater than 37 mph
(60 km/h).
• The vehicle speed is greater than 7 mph
(12 km/h)
.
• You reverse out of an angled parking
space. Cross Traffic Alert Behavior When
Trailer is Attached
Note:
The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
Cross traffic alert remains on when you
attach a trailer in vehicles that come with
blind spot information system with trailer
tow under the following conditions:
• You connect a trailer.
• The trailer is a bike rack or cargo rack
with a maximum length of
3 ft (1 m).
• You set the trailer length to
3 ft (1 m)
in the information display.
See
Blind Spot Information System
(page 266).
Switching the System On and Off
To switch the system on or off, adjust the
setting. Depending on your vehicle options,
the setting could be in the following:
• Information display.
See General
Information (page 120).
• Touchscreen. See Settings (page 535).
Note: The system turns on every time you
switch the ignition on. To permanently
switch the system off, contact an authorized
dealer.

STEERING
Electric Power Steering WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.

partly obscured pedestrians, or
pedestrians that the system cannot
distinguish from a group. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
WARNING: The system cannot
help prevent all crashes. Do not rely on
this system to replace driver judgment
and the need to maintain a safe distance
and speed.
Using the Pre-Collision Assist
System
The Pre-Collision Assist system is active
at speeds above approximately
3 mph
(5 km/h) and pedestrian detection is active
at speeds up to
50 mph (80 km/h). If your vehicle is rapidly approaching
another stationary vehicle, a vehicle
traveling in the same direction as yours, or
a pedestrian within your driving path, the
system provides three levels of
functionality:
1. Alert
2. Brake Support
3. Active Braking Alert
: When active, a flashing visual
warning appears and an audible warning
tone sounds.
Brake Support
: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking. The
system does not automatically apply the
brakes. If you press the brake pedal, the
system could apply additional braking up
to maximum braking force, even if you
lightly press the brake pedal.
Active Braking
: Active braking may
activate if the system determines that a
collision is imminent. The system may help
the driver reduce impact damage or avoid
the crash completely.
Note: Brake Support and Active Braking are
active at speeds up to
75 mph (120 km/h).
If the vehicle has a radar sensor or Adaptive
Cruise Control, then Brake Support and
Active Braking are active up to the maximum
speed of the vehicle.
Note: If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.
Note: The Pre-Collision Assist system
automatically disables when you select 4X4
LOW
or when you manually disable
AdvanceTrac ™.

Adjusting the Pre-Collision Assist
Settings
You can adjust the following settings by
using the information display controls. See
General Information (page 120).
• You can change Alert and Distance
Alert sensitivity to one of three possible
settings.
• You can switch Distance Indication and
Alert on or off.
• If required, you can switch Active
Braking on or off.
• If required, you can switch the entire
Pre-Collision Assist feature on or off.
Note: Active braking automatically turns
on every time you switch the ignition on.
Note: If your vehicle has a radar sensor, we
recommend that you switch the system off
if you install a snow plow or similar object
in such a way that it may block the radar
sensor. Your vehicle remembers the selected
setting across key cycles. Blocked Sensors Camera.

If a message regarding a blocked sensor
or camera appears in the information
display, the radar signals or camera images
are obstructed. If your vehicle has a radar
sensor, it is located behind the fascia cover
in the center of the lower grille. With a
blocked sensor or camera, the
Pre-Collision Assist system may not
function, or performance may reduce. The
following table lists possible causes and
actions for when this message displays.
Camera Troubleshooting Action
Cause
Clean the outside of the windshield in frontof the camera.
The windshield in front of the camera is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the camera to detect that there is no obstruction.
The windshield in front of the camera is
clean but the message remains in the display screen.

The Pre-Collision Assist system is tempor-
arily disabled. Pre-Collision Assist automat-ically reactivates a short time after the weather conditions improve.
Heavy rain, spray, snow or fog is interfering
with the radar signals.
The Pre-Collision Assist system is tempor-
arily disabled. Pre-Collision Assist automat-ically reactivates a short time after the weather conditions improve.
Swirling water or snow or ice on the surface
of the road may interfere with the radar signals.
Contact an authorized dealer to have theradar checked for proper coverage and operation.
Radar is out of alignment due to a front end
impact.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully. DRIVE CONTROL
Selectable Drive Modes
This provides a single location to control
multiple system performance settings such
as steering, handling and powertrain
response.
Changing the drive mode automatically
changes the functionality of the following
systems:
278
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Driving Aids

Note:
Please refer to the Body Builders
Layout Book for instructions about the
appropriate installation of additional
equipment.
Your vehicle is equipped with a driver and
passenger airbag supplemental restraint
system. The supplemental restraint system
activates in certain frontal and offset
frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while
snowplowing, which results in significant
vehicle decelerations, can deploy the
airbag. Such driving also increases the risk
of accidents.
Never remove or defeat the tripping
mechanisms designed into the snow
removal equipment by its manufacturer.
Doing so may cause damage to the vehicle
and the snow removal equipment as well
as possible airbag deployment.
Engine Temperature while Plowing
Your engine may run at a higher
temperature than normal because the
attached snowplow blade restricts airflow
to the radiator:
• If you are driving more than 15 mi
(24 km) at temperatures above
freezing, angle the plow blade either
full left or full right to provide
maximum airflow to the radiator.
• If you are driving less than
15 mi
(24 km) at speeds up to 45 mph
(72 km/h) in cold weather, you do not
need to worry about blade position to
provide maximum airflow.
Transmission Operation while
Plowing WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander. •
Shift transfer case to
4L (4WD Low)
when plowing in small areas at speeds
below
5 mph (8 km/h).
• Shift transfer case to
4H (4WD High)
when plowing larger areas or light snow
at higher speeds. Do not exceed 15 mph
(24 km/h)
.
• Do not shift the transmission from a
forward gear to
R (Reverse) until the
engine is at idle and the wheels have
stopped.
Outside Air Temperature While
Plowing
While plowing with your vehicle, the plow
blade can block the sensor airflow and
cause the outside air temperature reading
to be inaccurate.
A Ford wiring kit is available to relocate the
Outside Air Temperature sensor to the
plow blade frame to provide more
accurate outside air temperature readings.
Contact an authorized dealer for more
information.
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.
