2021 FORD F-150 warning lights

WHAT IS THE PERSONAL
SAFETY SYSTEM
An advanced safety system that protects
occupants in frontal crashes.
HOW DOES THE PERSONAL
SAFETY SYSTEM WORK
This system provides an improved level of
frontal crash protection to front seat
occupants and is designed to reduce the
risk of airbag-related injuries. The system
analyzes occupant conditions and crash
severity before activating the appropriate
safety devices. During a crash, the
restraints control module may deploy the
seatbelt pretensioners, and one or both
stages of the dual-stage airbags based on
crash severity and occupant conditions.
PERSONAL SAFETY SYSTEM
COMPONENTS
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front seat outermost seatbelts with
pretensioners, energy management
retractors and seatbelt usage sensors.
• Front passenger sensing system.
• Passenger airbag off and on indicators.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning light and
tone.
• The electrical wiring for the airbags,
crash sensors, seatbelt pretensioners,
front seatbelt usage sensors, front
passenger sensing system and
indicator lights.

the information display will then display
the selected four-wheel drive mode. While
shifts are in progress, the lights on the
four-wheel drive control switch can flash
and you could see messages in the
information display indicating that a shift
is in progress or to release the accelerator
pedal to improve shift performance.
Note:
Do not perform this operation if the
rear wheels are slipping or while applying
the accelerator pedal.
Note: You could hear some noise as the
system shifts or engages which is normal.
If the system detects a fault, a warning
message appears in the information
display. See Four-Wheel Drive –
Information Messages (page 299).

ADAPTIVE CRUISE CONTROL
LIMITATIONS
Sensor Limitations
WARNING: On rare occasions,
detection issues can occur due to the
road infrastructures, for example bridges,
tunnels and safety barriers. In these
cases, the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening,
if required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible. WARNING:
Large contrasts in
outside lighting can limit sensor
performance. WARNING:
The system only warns
of vehicles detected by the radar sensor.
In some cases there may be no warning
or a delayed warning. Apply the brakes
when necessary. Failure to follow this
instruction could result in personal injury
or death. WARNING:
The system may not
detect stationary or slow moving
vehicles below
6 mph (10 km/h). WARNING:
The system does not
detect pedestrians or objects in the road. WARNING:
The system does not
detect oncoming vehicles in the same
lane. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from
obstruction. WARNING:
The sensor may
incorrectly track lane markings as other
structures or objects. This can result in
a false or missed warning. Camera.
1.
Radar sensor.
2.
The camera is on the windshield behind
the interior mirror.
The radar sensor is in the lower grille.
Note: You cannot see the sensor. It is
behind a fascia panel.
Note: Keep the front of your vehicle free of
dirt, metal badges or objects. Vehicle front
protectors, aftermarket lights, additional
paint or plastic coatings could also degrade
sensor performance.
A message displays if something obstructs
the camera or the sensor. When something
blocks the sensor, the system cannot
detect a vehicle ahead and does not
function. See
Adaptive Cruise Control
– Information Messages (page 362).

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.
PRE-COLLISION ASSIST
LIMITATIONS
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 80 mph (130 km/h). If your vehicle has a
radar sensor included with adaptive cruise
control, then brake support and automatic
emergency braking are active up to the
maximum speed of your vehicle.
