2021 FORD F-150 warning light

•
Pull your vehicle over.
• Switch your vehicle off.
• Check for any objects lodged
underneath the front passenger seat
or cargo interfering with the seat.
• Remove the obstruction if found.
• Restart your vehicle.
• Wait at least two minutes and verify
that the airbag readiness light in the
instrument cluster is no longer
illuminated.
• If the airbag readiness light in the
instrument cluster remains illuminated,
there may be a problem due to the
front passenger sensing system.
Do not attempt to repair or service the
system. Take your vehicle in for service
immediately.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact your
Customer Relationship Center. See
Contacting Us (page 22). FRONT PASSENGER SENSING
SYSTEM PRECAUTIONS WARNING:
Sitting improperly, out
of position or with the seatback reclined
too far can take weight off the seat
cushion and affect the decision of the
passenger sensing system, resulting in
serious injury or death in the event of a
crash. Always sit upright against your
seat back, with your feet on the floor. WARNING:
Any alteration or
modification to the front passenger seat
may affect the performance of the front
passenger sensing system. This could
seriously increase the risk of injury or
death.

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or adding
equipment to the front of your vehicle
could affect the performance of the
airbag system, increasing the risk of
injury. This includes the hood, bumper
system, frame, front body structure, tow
hooks, hood pins, push bar and
snowplows.
Your vehicle has a collection of crash and
occupant sensors. These sensors provide
information to the restraints control
module which activates the following:
• Front seatbelt pretensioners.
• Driver airbag.
• Passenger airbag.
• Knee airbag(s).
• Seat mounted side airbags.
• Safety Canopy.
Based on the type of crash, the restraints
control module deploys the appropriate
safety devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following: The readiness light will not
illuminate immediately after you
switch the ignition on. •
The readiness light either flashes or
stays on.
• You hear a series of five tones. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced immediately.
Unless serviced, the system may not
function properly in the event of a crash.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, seatbelt usage)
were not appropriate to activate these
safety devices.
• The front airbags activate only in
frontal and near-frontal crashes. Front
airbags may activate in rollovers, side
impacts or rear impacts if the crash
causes sufficient frontal deceleration.
• The seatbelt pretensioners activate in
frontal, near-frontal and side crashes,
and in rollovers.
• The knee airbag(s) deploy based on
crash severity and occupant conditions.
• The side airbags inflate in certain side
impact crashes or rollover events. Side
airbags may activate in other types of
crashes if the vehicle experiences
sufficient sideways motion or
deformation.
• The Safety Canopy inflates in certain
side impact crashes or rollover events.
The Safety Canopy may activate in
other types of crashes if the vehicle
experiences sufficient sideways motion
or deformation, or a certain likelihood
of rollover.

HEADLAMPS –
TROUBLESHOOTING
HEADLAMPS – FREQUENTLY
ASKED QUESTIONS
Why is there condensation in the
headlamps?
Headlamps have vents to
accommodate normal changes in air
pressure. Condensation can be a
natural by-product of this design.
When moist air enters the lamp
assembly through the vents, there is a
possibility that condensation can
occur when the temperature is cold.
When normal condensation occurs, a
fine mist can form on the interior of the
lens. The fine mist eventually clears
and exits through the vents during
normal operation.
How much condensation is
acceptable? The presence of a fine mist, for
example no streaks, drip marks or
large droplets. A fine mist covers less
than 50% of the lens.
How long may it take for the
acceptable condensation to be
cleared? Clearing time may take as long as 48
hours under dry weather conditions.
How much condensation is
unacceptable? A water puddle inside the lamp.
Streaks, drip marks or large droplets
present on the interior of the lens.
What should I do if unacceptable
condensation is present? Have your vehicle checked as soon as
possible. Why do my headlamps turn off when I
have them switched on when I switch
my vehicle off?
The battery saver turns the headlamps
off after a short period of time after
you switch your vehicle off.
AUTOLAMPS
WHAT ARE AUTOLAMPS WARNING: The system does not
relieve you of your responsibility to drive
with due care and attention. You may

turn the headlamps on in low visibility
conditions, for example daytime fog.
Autolamps turn the headlamps on in low
light situations or when the windshield
wipers operate.
