2021 FORD F-150 sensor

WHAT IS CROSS TRAFFIC
ALERT
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
HOW DOES CROSS TRAFFIC
ALERT WORK
Cross traffic alert detects vehicles that
approach at a speed between 4–
37 mph
(6–60 km/h). Coverage decreases when
the sensors are partially, mostly or fully
obstructed. The sensor on the left-hand side is only
partially obstructed and zone coverage on
the right-hand side is maximized.
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.
Note:
Slowly reversing helps increase the
coverage area and effectiveness. CROSS TRAFFIC ALERT
PRECAUTIONS 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.
CROSS TRAFFIC ALERT
LIMITATIONS
The system may not correctly operate
when any of the following occur:
• Something is blocking the sensors.
• 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)
.
• Your vehicle speed is greater than
7 mph (12 km/h)
.
• You reverse out of an angled parking
space.

Cross Traffic Alert Limitations
with a Trailer Attached
The system remains on when you attach
a trailer in vehicles 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 instrument cluster display.
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.
SWITCHING CROSS TRAFFIC
ALERT ON AND OFF
To switch cross traffic alert on or off use
the touchscreen.
1. Press
Features on the touchscreen.
2. Press
Driver Assistance.
3. Switch
Cross Traffic Alert on or off.
Note: The system switches on every time
you switch the ignition on. To permanently
switch the system off, contact an authorized
dealer. LOCATING THE CROSS
TRAFFIC ALERT SENSORS The sensors are inside the brake lamp 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 may affect system
accuracy.
If something is blocking the sensors, a
message may appear in the information
display when you shift into reverse (R).
Note: Bike and cargo racks could cause
false alerts due to obstruction of the sensor.
We recommend switching the feature off
when using a bike or cargo rack.
CROSS TRAFFIC ALERT
INDICATORS When the cross traffic alert
detects an approaching vehicle,
a tone sounds, a warning lamp
illuminates in the relevant exterior mirror
and arrows appear in the information
display to show which side the vehicle is
approaching from.

If the system malfunctions, a warning lamp
illuminates in the instrument cluster and
a message appears in the information
display. Have your vehicle checked as soon
as possible.
Note:
If arrows do not display, a message
appears in the information display.
Note: In some conditions, the system could
alert you, even when there is nothing in the
detection zone, for example a vehicle
passing further away from your vehicle.

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.

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

assist on or off.
Note: Automatic emergency braking and
evasive steering turn on every time you
switch the ignition on.

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.
Note: If you switch automatic emergency

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.
