FORD F-150 2021 Owners Manual

WARNING: Take additional care if
your vehicle is heavily loaded or you are
towing a trailer. These conditions could
result in reduced performance of this
system. Failure to follow this instruction
could result in the loss of control of your
vehicle, 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. WARNING:
In situations where the
vehicle camera has limited detection
capability, this may reduce system
performance. These situations include
but are not limited to direct or low
sunlight, vehicles at night without tail
lights, unconventional vehicle types,
pedestrians with complex backgrounds,
running pedestrians, 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.
PRE-COLLISION ASSIST
LIMITATIONS - POLICE
RESPONDER
Pre-collision assist depends on the
detection ability of its camera and sensors.
Any obstructions or damage to these areas
can limit detection or prevent the system
from functioning. See
Locating the
Pre-Collision Assist Sensors (page 399).
The system is active at speeds above
3 mph (5 km/h)
. Note:
The pre-collision assist system
automatically disables when you select
four-wheel drive low, manually disable
AdvanceTrac ™, or select rock crawl mode.
Note: Brake support and automatic
emergency braking are active at speeds up
to
75 mph (120 km/h).
Pedestrian Detection Limitations
Pedestrian detection is active at speeds
up to
50 mph (80 km/h).
Pedestrian detection operates optimally
when detected hazards are clearly
identifiable. System performance may
reduce in situations where pedestrians are
running, partly obscured, have a complex
background, or cannot be distinguished
from a group.

control, then brake support and automatic
emergency braking are active up to the
maximum speed of your vehicle.

Pedestrian Detection Limitations
Pedestrian detection is active at speeds
up to 50 mph (80 km/h).
Pedestrian detection operates optimally
when detected hazards are clearly
identifiable. System performance may
reduce in situations where pedestrians are
running, partly obscured, have a complex
background, or when the system cannot
distinguish pedestrians from a group.
Intersection Assist
(If Equipped)
If your vehicle comes with a radar sensor
included in adaptive cruise control, the
pre-collision assist system may operate in
a scenario where you are turning across an
oncoming vehicle's path. Detection of
vehicles driving in an oncoming direction
is active if your vehicle is driving at speeds
up to
19 mph (30 km/h). SWITCHING PRE-COLLISION

in such a way that it may block the radar
sensor. Your vehicle remembers the selected
setting across key cycles.
Note: If you switch automatic emergency
braking off, evasive steering assist switches
off.
LOCATING THE PRE-
COLLISION ASSIST SENSORS
- POLICE RESPONDER Camera.
1 If a message regarding a blocked camera
appears in the instrument cluster display,
something is obstructing the camera
images. With a blocked camera, the
system may not function, or performance
may reduce. See Pre-Collision Assist –
Information Messages (page 404).
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 your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could 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 recalibrates successfully.

If a message regarding a blocked sensor
or camera appears in the information
display, something is obstructing the radar
signals or camera images. The radar sensor
is behind the fascia cover in the center of
the lower grille. With a blocked sensor or
camera, the system may not function, or
performance may reduce. See
Pre-Collision Assist – Information
Messages (page 404).
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
could change. This could cause missed or
false vehicle detections. Have your vehicle
serviced 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 could 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 recalibrates successfully.

EVASIVE STEERING ASSIST
(IF
EQUIPPED)
WHAT IS EVASIVE STEERING
ASSIST
If your vehicle is rapidly approaching a road
user, evasive steering assist helps you steer
around the road user.
After you turn the steering wheel in an
attempt to avoid a crash with the road
user, the system applies additional steering
torque to help you steer around the road
user. After you pass the road user, the
system applies steering torque when you
turn the steering wheel to steer back into
the lane. The system deactivates after you
fully pass the road user.
Note: Road users are defined as another
stationary vehicle in the same lane or a
vehicle traveling in the same lane in the
same direction as you. See
Pre-Collision
Assist Precautions (page 396). EVASIVE STEERING ASSIST
LIMITATIONS
Evasive steering assist only activates when
all the following occur:
•
Automatic emergency braking and
evasive steering assist are on.
• The system detects a road user ahead
and starts to apply the brakes.
• You significantly turn the steering
wheel to steer around a road user.
Note: Evasive steering assist does not
automatically steer around a road user. If
you do not turn the steering wheel, evasive
steering assist does not activate.
Note: Evasive steering assist does not
activate if the distance to the road user
ahead is too small and the system cannot
avoid a crash.
Note: Evasive steering does not activate
with cyclists or pedestrians.
SWITCHING EVASIVE STEERING
ASSIST ON AND OFF
To switch the system on or off, use the
touchscreen:
1. Press
Features on the touchscreen.
2. Press
Driver Assistance.
3. Press
Pre-Collision Assist.
4. Switch
Evasive Steering on or off.
Note: If you switch automatic emergency
braking off, evasive steering assist turns off.
Note: Automatic emergency braking and
evasive steering assist turn on every time
you switch the ignition on.
