2006 FORD EXPLORER sensor

Before returning the seatback to its original position, make sure
that cargo or any objects are not trapped behind the seatback.
After returning the seatback to its original position, pull on the
seatback to ensure that it has fully latched. An unlatched seat may
become dangerous in the event of a sudden stop or collision.
SAFETY RESTRAINTS
Personal Safety SystemY
The Personal Safety Systemyprovides an improved overall level of
frontal crash protection to front seat occupants and is designed to help
further reduce the risk of airbag-related injuries. The system is able to
analyze different occupant conditions and crash severity before activating
the appropriate safety devices to help better protect a range of
occupants in a variety of frontal crash situations.
Your vehicle's Personal Safety Systemyconsists of:
²Driver and passenger dual-stage airbag supplemental restraints.
²Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
²Driver's seat position sensor.
²Front passenger sensing system
²ªPassenger airbag offº or ªpass airbag offº indicator lamp
²Front crash severity sensor.
²Restraints Control Module (RCM).
²Restraint system warning light and back-up tone.
²The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, front passenger sensing system, and indicator lights.
How does the Personal Safety SystemYwork?
The Personal Safety Systemycan adapt the deployment strategy of your
vehicle's safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints Control Module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage airbag supplemental restraints based on crash
severity and occupant conditions.

The fact that the pretensioners or airbags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal Safety Systemydetermined
the accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front airbags are designed
to activate only in frontal and near-frontal collisions, not rollovers,
side-impacts, or rear-impacts unless the collision causes sufficient
longitudinal deceleration.
Driver and passenger dual-stage airbag supplemental restraints
The dual-stage airbags offer the capability to tailor the level of airbag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAirbag supplemental restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal Safety Systemyto distinguish between different
levels of crash severity and modify the deployment strategy of the
dual-stage airbags and safety belt pretensioners.
Driver's seat position sensor
The driver's seat position sensor allows your Personal Safety Systemyto
tailor the deployment level of the driver dual-stage airbag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver airbag by providing a lower airbag output level.
Front passenger sensing system
For airbags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the airbag when it begins to inflate. For some occupants, this occurs
because they are initially sitting very close to the airbag. For other
occupants, this occurs when the occupant is not properly restrained by
seat belts or child safety seats and they move forward during pre-crash
braking. The most effective way to reduce the risk of unnecessary
injuries is to make sure all occupants are properly restrained. Accident
statistics suggest that children are much safer when properly restrained
in the rear seating positions than in the front.

Air bags can kill or injure a child in a child seat.NEVERplace a
rear-facing child seat in front of an active air bag. If you must
use a forward-facing child seat in the front seat, move the seat all the
way back.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The front passenger sensing system can automatically turn off the front
passenger airbag and passenger seat-mounted side airbag. The system is
designed to help protect small (child size) occupants from frontal airbag
deployments when they are seated or restrained in the front passenger
seat contrary to proper child-seating or restraint usage
recommendations. Even with this technology, parents areSTRONGLY
encouraged to always properly restrain children in the rear seat. The
sensor also turns off the passenger front airbag and passenger
seat-mounted side airbag (if equipped) when the passenger seat is empty
and the safety belt is unbuckled, or when a child or a small person
occupies the front passenger seat and the safety belt is unbuckled.
Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety Systemyto tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety restraintssection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant's body
during frontal collisions, and in side collisions and rollovers when the
vehicle is equipped with the optional Safety Canopyysystem. This
maximizes the effectiveness of the safety belts. In frontal collisions, the
safety belt pretensioners can be activated alone or, if the collision is of
sufficient severity, together with the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow webbing
to be pulled out of the retractor in a gradual and controlled manner in
response to the occupant's forward momentum. This helps reduce the risk
of force-related injuries to the occupant's chest by limiting the load on the
occupant. Refer toSafety restraintssection in this chapter.

Determining if the Personal Safety SystemYis operational
The Personal Safety Systemyuses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety Systemyis not
required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. In addition, the RCM also monitors the restraints
warning light in the instrument cluster. A difficulty with the system is
indicated by one or more of the following:
²The warning light will either flash or stay lit.
²The warning light will not illuminate immediately after the ignition is
turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety Systemyserviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
To reduce the risk of injury, make sure children sit in the back
seat where they can be properly restrained.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an airbag
supplemental restraint system (SRS) is provided.

²Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
Unbuckle the combination lap and shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the combination lap and shoulder belt
system at all passenger seating positions must be checked by an
authorized dealer to verify that the ªautomatic locking retractorº
feature for child seats is still functioning properly, in addition to other
checks for proper safety belt system function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if the
safety belt assembly ªautomatic locking retractorº feature or any
other safety belt function is not operating properly. In addition, all safety
belts should be checked for proper function. Failure to replace the belt
and retractor assembly could increase the risk of injury in collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and Safety Canopyy
system (if equipped). When the safety belt pretensioner deploys, the lap
and shoulder belt are tightened.
When the optional Safety Canopyysystem and/or the front airbags are
activated, the safety belt pretensioners for the driver and right front
passenger seating positions will be activated when the respective seatbelt
is properly buckled.
The driver and front passenger seat belt system (including
retractors, buckles and height adjusters) must be replaced if the
vehicle is involved in a collision that results in deployment of front
airbags, seat-mounted side airbags and Safety Canopyy(if equipped),
and safety belt pretensioners.
Refer to theSafety belt maintenancesection in this chapter.

All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 10 inches (25 cm)
between an occupant's chest and the driver airbag module.
Never place your arm over the airbag module as a deploying air
bag can result in serious arm fractures or other injuries.
To properly position yourself away from the airbag:
²Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
²Recline the seat slightly one or two degrees from the upright position.
Do not put anything on or over the airbag module. Placing
objects on or over the airbag inflation area may cause those
objects to be propelled by the airbag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your authorized
dealer.
Modifications to the front end of the vehicle, including frame,
bumper, front end body structure and non-Ford tow hooks may
effect the performance of the airbag sensors increasing the risk of
injury. Do not modify the front end of the vehicle with anything other
than authorized Ford accessories for your vehicle.
Additional equipment may affect the performance of the airbag
sensors increasing the risk of injury. Please refer to theBody
Builders Layout Bookfor instructions about the appropriate
installation of additional equipment.

Children and airbags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
Airbags can kill or injure a
child in a child seat.
NEVERplace a rear-facing child
seat in front of an active airbag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.
How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates airbag
inflation.
The fact that the airbags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Front airbags are designed to activate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.

The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger's frontal
air bag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger's seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger's frontal air bag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger's frontal air bag if:
²the front passenger seat is unoccupied, or has small/medium objects in
the front seat,
²the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer's instructions,
²the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer's
instructions,
²the system determines that a small child is present in a booster seat,
²a front passenger takes his/her weight off of the seat for a period of
time,
