Lincoln Nautilus: Airbags / Front Passenger Sensing System
What Is the Front Passenger Sensing System
This system detects a properly seated
occupant and determines if the front
passenger airbag should be enabled.
How Does the Front Passenger Sensing System Work
The system uses a passenger airbag status
indicator which illuminates indicating that the
front passenger frontal airbag is either
enabled or disabled.
Note: When you first switch the ignition on,
the passenger airbag status indicator off and
on lamps illuminate for a short period to
confirm they are functional.
The indicator lamps are in the overhead
console.
The front passenger sensing system is
designed to disable the front passenger
frontal airbag under these conditions:
- The front passenger seat is unoccupied.
- The system determines an infant is
present in a child restraint.
- A passenger takes their weight off of the
seat for a period of time.
- If there is a problem with the airbag
system or the passenger sensing system.
Even with this technology, parents are
strongly encouraged to always properly
restrain children in the rear seat.
- When the front passenger sensing
system disables the front passenger
frontal airbag, the passenger airbag
status indicator illuminates the off lamp.
- If you have installed the child restraint
and the passenger airbag status indicator
illuminates the on lamp, switch your
vehicle off, remove the child restraint
from your vehicle and reinstall the
restraint following the child restraint
manufacturer's instructions.
The front passenger sensing system works
with sensors that are part of the front
passenger seat and seatbelt. The sensors
are designed to detect the presence of a
properly seated occupant and determine if
the front passenger frontal airbag should be
enabled.
- When the front passenger sensing
system enables the front passenger
frontal airbag, the passenger airbag
status indicator illuminates the on lamp.
If a person of adult size is sitting in the front
passenger seat, but the passenger airbag
status indicator off lamp is illuminated, it is
possible that the person is not sitting
properly in the seat. If this happens:
- Switch your vehicle off and ask the
person to place the seat backrest in an
upright position.
- Have the person sit upright in the seat,
centered on the seat cushion, with the
person's legs comfortably extended.
- Restart your vehicle and have the person
remain in this position for about two
minutes. This allows the system to detect
that person and enable the passenger
frontal airbag.
- If the indicator off lamp remains
illuminated even after this, you should
advise the person to ride in the rear seat.
After all occupants have adjusted their seats
and put on seatbelts, it is very important that
they continue to sit upright, leaning against
the seat backrest, and centered on the seat
cushion, with their feet comfortably extended
on the floor.
Sitting improperly can increase the chance
of injury in a crash event. For example, if an
occupant slouches, lies down, turns
sideways, sits forward, leans forward or
sideways, or puts one or both feet up, the
chance of injury during a crash greatly
increases.
If you think that the state of the passenger
airbag status indicator lamp is incorrect,
check for the following:
- Objects lodged underneath the seat.
- Objects between the seat cushion and
the center console.
- Objects hanging off the seat backrest.
- Objects stowed in the seat backrest map
pocket.
- Objects placed on the occupant's lap.
- Cargo interference with the seat
- Other passengers pushing or pulling on
the seat.
- Rear passenger feet and knees resting
or pushing on the seat.
The listed conditions could cause the weight
of a properly seated occupant to be
incorrectly interpreted by the front passenger
sensing system. The person in the front
passenger seat could appear heavier or
lighter due to the conditions listed.
Make sure the front passenger
sensing system is operating
properly.
If the airbag readiness light is on, do the
following:
- 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.
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.
