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 air bag-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:
²Driver and passenger dual-stage air bag supplemental restraints. Refer
to theAir bag supplemental restraintssection in this chapter.
²Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors. Refer to theSafety beltssection in this
chapter.
²Driver's seat position sensor.
²Front crash severity sensor.
²Restraints Control Module (RCM) with impact and safing sensors.
²An indicator light and back-up tone.
²The electrical wiring for the air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors and driver's seat position
sensor.
How does the personal safety system work?
The Personal Safety System uses a collection of sensors to gather
information about the driver's seat position, driver and front outboard
passenger's safety belt usage and accident severity. Then, dual-stage
inflating air bags are combined with safety belt pretensioners and energy
management retractors to help provide enhanced occupant protection in
frontal crashes.
The driver's seat position sensor determines if the seat is fore or aft of a
reference position. Similarly, the safety belt usage sensors determine if
the driver and front outboard passenger safety belts are fastened. These
sensors provide the ability to tailor the air bag deployment based upon
how close the driver's seat is to the steering wheel and whether or not
the safety belts are fastened.
The dual-stage air bags offer the ability to tailor the air bag inflation with
two energy levels. A lower, less forceful energy level is provided for more

common, moderate-severity impacts. A higher energy level is provided
for the most severe impacts. Whether or not the air bag deploys at all
can also be different for the driver versus the passenger based upon
driver's seat position and safety belt usage allowing further tailoring of
the system.
Determining if the personal safety system is operational
The Personal Safety System uses a warning indicator light in the
instrument cluster or a back-up tone to indicate the condition of the
system. Refer to theRestraints Warning Indicatorsection in the
Instrumentationchapter. Routine maintenance of the Personal Safety
System is not required.
The RCM (restraints control module) monitors its own internal circuits
and the circuits for the air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt usage sensors and driver's seat
position sensor. In addition, the RCM also monitors the restraints
warning indicator light in the instrument cluster. A difficulty with the
system is indicated by one or more of the following:
²The indicator light will either
flash or stay lit.
²The indicator light will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and indicator light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.

Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The safety belt pretensioners are designed to activate only when the
safety belts are fastened during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt pretensioner is a
device which tightens the webbing of the lap and shoulder belts in such
a way that they fit more snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to theSafety belt maintenancesection in this
chapter.
In the event of a collision resulting in the deployment of the
front air bags, the front safety belts must be replaced if they
were in use. Failure to replace the safety belt assembly could result in
severe personal injuries in the event of a collision.
Safety belt usage sensors
The driver and front outboard passenger safety belt buckles are
equipped with sensors that detect if the safety belts are fastened. The
sensors provide information to the Personal Safety System which can
then adapt the air bag deployment or safety belt pretensioner activation
based upon safety belt usage.
The Personal Safety System provides the most benefit to belted
occupants. The system monitors and tailors the air bag
deployment based upon safety belt usage. Failure to properly wear
your safety belt will increase your risk of injury.

Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat tether bracket assemblies (if equipped),
LATCH child seat tether anchors and lower anchors (if equipped), and
attaching hardware, should be inspected after a collision. Ford
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 toCleaning and maintaining the safety beltsin the
Maintenacne and Caresection.
AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM
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

and may help Ford better understand real world collisions and further
improve the safety of future vehicles.
The air bag supplemental restraint system is designed to work in
conjunction with the safety belts to help protect the driver and front
outboard passenger from certain upper body injuries. The term
ªsupplemental restraintº means the air bags are intended as a
supplement to the safety belts. Air bags alone cannot protect as well as
air bags plus safety belts in impacts for which the air bags are designed
to deploy, and air bags do not offer any protection in crashes for which
they do not deploy.
HOW DO THE AIR BAG SUPPLEMENTAL RESTRAINTS WORK?
The air bag supplemental restraint system consists of:
²driver and passenger dual stage air bag modules (which include the
inflators and air bags).
²side air bags (if equipped). Refer toSide air bag systemlater in this
chapter.
²one or more impact and safing sensors.
²the same indicator light, RCM (restraints control module) and
diagnostic unit used for the Personal safety system.
The air bag supplemental restraints are an intergral part of the Personal
Safety System. They are designed to be deployed in cases where the
Personal Safety System has determined the occupant conditions and
crash severity are appropriate to activate these devices. Refer to the
Personal Safety Systemsection in this chapter.

Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.
Modifications to the front end of the vehicle, including frame,
bumper, front end body structure and tow hooks may affect the
performance of the air bag sensors increasing the risk of injury. Do not
modify the front end of the vehicle.
Children and air bags
For additional important safety
information, read all information on
safety restraints in this guide.
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.
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.

How does the side air bag system work?
The side air bag system consists of
the following:
²An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
²A special seat cover designed to
allow airbag deployment.
²The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
²Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the 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 of the type sufficient to cause activation. Side air bags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.

Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
TRACTION CONTROLY(IF EQUIPPED)
Your vehicle may be equipped with the optional Traction Controly
system. This system helps you maintain the stability and steerability of
your vehicle. It is especially useful on slippery and/or hilly road surfaces.
The system operates by detecting and controlling wheel spin. The system
borrows many of the electronic and mechanical elements already present
in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess front wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the front
brakes in conjunction with engine torque reductions. Engine torque
reduction is realized via the fully electronic spark and fuel injection
systems. This process is very sensitive to driving conditions and very fast
acting. The front wheels ªsearchº for optimum traction several times a
second and adjustments are made accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow, ice covered
and gravel roads.
