2003 FORD EXPLORER SPORT TRAC sensor

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 Canopy

system. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
When the Safety Canopy
system 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 the right 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 air bags or Safety Canopy
and safety belt
pretensioners.
Refer to theSafety belt maintenancesection in this chapter.
Safety belt warning light and indicator chime
The seat belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

a collision. Ford Motor Company recommends that all safety belt
assemblies used in vehicles involved in a collision be replaced. However,
if the collision was minor and a qualified technician finds that the belts
do not show damage and continue to operate properly, they do not need
to be replaced. Safety belt assemblies not in use during a collision should
also be inspected and replaced if either damage or improper operation is
noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
Refer toInteriorin theCleaningchapter.
AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Your vehicle is equipped with a crash sensing and diagnostic module
which records information about the air bag and sensor systems. In the
event of a collision this module may save information related to the
collision including information about the air bag system and impact
severity. This information will assist Ford Motor Company in servicing
the vehicle and in helping to better understand real world collisions and
further improve the safety of future vehicles.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.

How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains a
longitudinal deceleration sufficient
to cause the air bag sensors to close
an electrical circuit that initiates air
bag inflation. The fact that the air
bags did not inflate in a collision
does not mean that something is
wrong with the system. Rather, it
means the forces were not sufficient
enough to cause activation. Air bags
are designed to inflate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.
The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder or sodium compounds which
may irritate the skin and eyes, but
none of the residue is toxic.
While the SRS is designed to help
reduce serious injuries, contact with
a deploying air bag may also cause
abrasions, swelling or temporary
hearing loss. Because air bags must
inflate rapidly and with considerable
force, there is the risk of death or
serious injuries such as fractures, facial and eye injuries or internal
injuries, particularly to occupants who are not properly restrained or are
otherwise out of position at the time of air bag deployment. It is
extremely important that occupants be properly restrained as far away
from the air bag module as possible while maintaining vehicle control.
The SRS consists of:
•driver and passenger air bag modules (which include the inflators and
air bags)
•one or more impact and safing sensors

How does the Safety Canopysystem work?
The design and development of the
Safety Canopy
system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Air Bag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy
).
The Safety Canopy
system
consists of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of vehicle).
•A headliner designed to flex open
above the side doors to allow Safety Canopy
deployment.
•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two crash sensors mounted in the b-pillars (one on each side).
•Two crash sensors located at the c-pillar (one on each side).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopy
system, in combination with seat belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats. The Safety Canopy
will not interfere
with children restrained using a properly installed child or booster seat
because it is designed to inflate downward from the headliner above the
doors along the side window opening.
The Safety Canopy
system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy
inflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
The Safety Canopy
is mounted to roof side-rail sheet metal, behind the
headliner, above the first and second row seats. In certain lateral
