light FORD EXPLORER 2008 4.G Repair Manual

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 System™
The Personal Safety System™ provides 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 System™ consists of:
•Driver and passenger dual-stage airbag supplemental restraints.
•Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
•Driver’s seat position sensor.
•Front passenger sensing system
•“Passenger airbag off” or “pass airbag off” indicator lamp
•Front crash severity sensor.
•Restraints Control Module (RCM).
•Restraint system warning light and back-up tone.
•The 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 System™ work?
The Personal Safety System™ can 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 may activate 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.

Determining if the Personal Safety System™ is operational
The Personal Safety System™ uses a warning light in the instrument cluster
or a back-up tone to indicate the condition of the system. Refer to the
Warning lights and chimessection in theInstrument Clusterchapter.
Routine maintenance of the Personal Safety System™ is 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, front
passenger sensing system, 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:
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after the ignition is
turned on.
•A 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
System™ serviced 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.

Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.
Conditions of operation
If... Then...
The driver’s safety belt is not
buckled before the ignition
switch is turned to the ON
position...The safety belt warning light
illuminates 1-2 minutes and the
warning chime sounds 4-8 seconds.
The driver’s safety belt is
buckled while the indicator
light is illuminated and the
warning chime is sounding...The safety belt warning light and
warning chime turn off.
The driver’s safety belt is
buckled before the ignition
switch is turned to the ON
position...The safety belt warning light and
indicator chime remain off.
Belt-Minder
The Belt-Minderfeature is a supplemental warning to the safety belt
warning function. This feature provides additional reminders by
intermittently sounding a chime and illuminating the safety belt warning
light in the instrument cluster when the driver’s and front passenger’s
safety belt is unbuckled.
The Belt-Minderfeature uses information from the front passenger
sensing system to determine if a front seat passenger is present and
therefore potentially in need of a warning. To avoid activating the
Belt-Minderfeature for objects placed in the front passenger seat,
warnings will only be given to large front seat occupants as determined
by the front passenger sensing system.
Both the driver’s and passenger’s safety belt usages are monitored and
either may activate the Belt-Minderfeature. The warnings are the same
for the driver and the front passenger. If the Belt-Minderwarnings have
expired (warnings for approximately 5 minutes) for one occupant (driver
or front passenger), the other occupant can still activate the
Belt-Minderfeature.

The following are reasons most often given for not wearing safety belts
(All statistics based on U.S. data):
Reasons given... Consider...
“Crashes are rare events”36700 crashes occur every day.The
more we drive, the more we are
exposed to “rare” events, even for
good drivers.1 in 4 of us will be
seriously injured in a crash during
our lifetime.
“I’m not going far”3of4fatal crashes occur within25
miles (40 km) of home.
“Belts are uncomfortable” We design our safety belts to enhance
comfort. If you are uncomfortable -
try different positions for the safety
belt upper anchorage and seatback
which should be as upright as
possible; this can improve comfort.
“I was in a hurry”Prime time for an accident.
Belt-Minderreminds us to take a few
seconds to buckle up.
“Safety belts don’t work”Safety belts,when used properly,
reduce risk of deathto front seat
occupants by45% in cars,and by
60% in light trucks.
“Traffic is light”Nearly 1 of 2 deaths occur in
single-vehicle crashes,many when
no other vehicles are around.
“Belts wrinkle my clothes” Possibly, but a serious crash can do
much more than wrinkle your clothes,
particularly if you are unbelted.
“The people I’m with don’t
wear belts”Set the example, teen deaths occur 4
times more often in vehicles with
TWO or MORE people. Children and
younger brothers/sisters imitate
behavior they see.

Before following the procedure, make sure that:
•The parking brake is set
•The gearshift is in P (Park) (automatic transmission)
•The ignition switch is in the OFF position
•The driver and front passenger safety belts are unbuckled
While the design allows you to deactivate your Belt-Minder, this
system is designed to improve your chances of being safely
belted and surviving an accident. We recommend you leave the
Belt-Mindersystem activated for yourself and others who may use the
vehicle. To reduce the risk of injury, do not deactivate/activate the
Belt-Minderfeature while driving the vehicle.
1. Turn the ignition switch to the RUN (or ON) position. DO NOT START
THE ENGINE.
2. Wait until the safety belt warning light turns off (Approximately 1
minute).
•Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
3. For the seating position being disabled, at a moderate speed, buckle
then unbuckle the safety belt nine times, ending in the unbuckled state.
Step 3 must be completed within 50 seconds after the safety belt
warning light turns off.
•After Step 3, the safety belt warning light will be turned on for three
seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minderfeature for that seating position if it
is currently enabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds.
•This will enable the Belt-Minderfeature for that seating position if it
is currently disabled. As confirmation, the safety belt warning light will
flash four times per second for three seconds, followed by three
seconds with the light off, then followed by the safety belt warning
light flashing four times per second for three seconds again.

Important SRS precautions
The SRS is designed to work with
the safety belt to help protect the
driver and right front passenger
from certain upper body injuries.
Airbags DO NOT inflate slowly;
there is a risk of injury from a
deploying airbag.
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
airbag can result in serious arm fractures or other injuries.
To properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline 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.

Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
•driver and passenger airbag modules (which include the inflators and
airbags).
•seat-mounted side airbags. Refer toSeat-mounted side airbag system
later in this chapter
•Safety Canopy™ system. Refer toSafety Canopy™ systemlater in
this chapter.
•one or more impact and safing sensors.
•a readiness light and tone.
•diagnostic module.
•and the electrical wiring which connects the components.
•Front passenger sensing system. Refer toFront passenger sensing
system.later in this chapter.
•“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing systemlater in this chapter.
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
airbag 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 airbag should be enabled (may inflate) or
disabled (will not inflate).

The front passenger sensing system may detect small or medium objects
placed on the seat cushion. For most objects that are in the front
passenger seat, the passenger airbag will be disabled. Even though the
passenger airbag is disabled, thepass airbag offlamp may or may not
be illuminated according to the table below.
ObjectsPass Airbag Off
Indicator LampPassenger Airbag
Small (i.e. 3 ring
binder, small purse,
bottled water)Unlit Disabled
Medium (i.e. heavy
briefcase, fully packed
luggage)Lit Disabled
Empty seat, or small
to medium object with
safety belt buckledLit Disabled
If you think that the status of the passenger airbag off indicator lamp is
incorrect, check for the following:
•Objects lodged underneath the seat
•Objects between the seat cushion and the center console (if
equipped)
•Objects hanging off the seat back
•Objects stowed in the seatback map pocket (if equipped)
•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
•Check to see if the clear objects by pass seat warning is displaying in
the message center. Refer tomessage centerin theDriver controls
chapter.
The conditions listed above may 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 may appear heavier or
lighter due to the conditions described in the list above.

Any alteration/modification to the front passenger seat may
affect the performance of the front passenger sensing system.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toAirbag readinesssection
in theInstrument Clusterchapter. 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 either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at an authorized dealer immediately. Unless serviced, the system may not
function properly in the event of a collision.
Seat-mounted side airbag system
Do not place objects or mount equipment on or near the airbag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying airbag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side airbags and
increase the risk of injury in an accident.
Do not lean your head on the door. The side airbag could injure
you as it deploys from the side of the seatback.
