AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM
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
“supplemental restraint”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.
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. Air
bags DO NOT inflate slowly; there is
a risk of injury from a deploying air
bag.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag (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 25 cm (10 inches)
between an occupant’s chest and the driver air bag module.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
To properly position yourself away from the air bag:
•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 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 systems or its fuses. See your Ford or
Lincoln Mercury dealer.
Modifying or adding equipment 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 system, increasing
the risk of injury. Do not modify the front end of the vehicle.

Children and air bags
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.
Determining if the system is operational
The supplemental restraint system uses a warning indicator in the
instrument cluster or a back-up tone to indicate the condition of the
system. Refer to theWarning lightsection in theInstrument cluster
chapter. Routine maintenance of the air bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light (same light
for front and side air bag system)
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 supplemental
restraint 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.

How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal 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.
Front 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 (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system 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. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.

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 air bag modules (which include the inflators and
air bags).
•side air bags (if equipped). Refer toSide air bag 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.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The driver’s air bag and side air
bag are not part of the front passenger sensing system. 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 not.
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to turn off the front passenger’s frontal air bag if:
•the front passenger seat is unoccupied,
•an infant or small child weighing less than 50 pounds (23 kg) is in the
front seat, either in a child restraint, in a booster seat, or sitting
directly on the vehicle seat,
•a front passenger takes his/her weight off the seat for a period of time

For larger children and very small adults, the passenger sensing system
may leave the air bag system enabled, or turn it OFF. The occupant’s
seating position may determine whether or not the air bag is enabled.
Even with Advanced Restraint Systems, children 12 and under
should be properly restrained in the back seat.
When the front passenger seat is
occupied and the sensing system
has turned off the passenger’s
frontal air bag, thepassenger airbag
offorpass airbag offindicator will
light and stay lit to remind you that
the front passenger frontal air bag is
off. When the front passenger seat is
not occupied (empty seat) or in the
event that the front passenger
frontal air bag is enabled (may
inflate), the indicator light will be unlit.
The indicator light is located in the center stack of the instrument panel
to the right of the radio.
The front passenger sensing system is designed to turn off the front
passenger’s frontal air bag when a rear facing infant seat, a
forward-facing child restraint, or a booster seat is detected. If the child
restraint has been installed and the indicator is not lit, then turn the
vehicle off, remove the child restraint from the vehicle and reinstall the
restraint following the child restraint manufacturer’s directions.
The front passenger sensing system is designed to enable (may inflate)
the right front passenger’s frontal air bag anytime the system senses that
a person of adult size is sitting properly in the front passenger seat.
When the passenger sensing system has allowed the air bag to be
enabled, the indicator will be unlit and stay unlit to remind you that the
air bag is enabled (may inflate).
If a person of adult-size is sitting in the front passenger’s seat, but the
passenger air bag offorpass air bag offindicator is lit, it could be
that the person isn’t sitting properly in the seat. If this happens, turn the
vehicle off and ask the person to place the seatback in the full upright
position, then sit upright in the seat, centered on the seat cushion, with
the person’s legs comfortably extended. Restart the vehicle and have the
person remain in this position for about two minutes. This will allow the
system to detect that person and then enable the passenger’s air bag. If

the indicator lamp remains lit even after this, then the occupant should
be advised to ride in the back seat.
After all occupants have adjusted their seats and put on seatbelts, it’s
very important that they continue to sit upright, with their back against
the seatback, with their feet comfortably extended on the floor while the
vehicle is still in motion. 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 is greatly increased.
Sitting improperly out of position or with the seat back reclined
too far can take off weight from the seat cushion and affect the
decision of the passenger sensing system, resulting in serious injury or
death in a crash. Always sit upright against your seatback, with your
feet on the floor.
In case there is a problem with the passenger sensing system, the airbag
readiness light in the instrument cluster will stay lit. Do NOT attempt to
repair or service the system; take your vehicle immediately to the dealer.
If it is necessary to modify an advanced front air bag system to
accommodate a person with disabilities, contact the Ford Customer
Relationship Center at the phone number shown in the Customer
Assistance section of this Owner’s Guide.
Side air bag system (if equipped)
Do not place objects or mount equipment on or near the air bag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying air bag. 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 air bags and
increase the risk of injury in an accident.
Do not lean your head on the door. The side air bag could injure
you as it deploys from the side of the seatback.

Do not attempt to service, repair, or modify the air bag SRS, its
fuses or the seat cover on a seat containing an air bag. See your
Ford or Lincoln Mercury dealer.
All occupants of the vehicle should always wear their safety belts
even when an air bag SRS is provided.
How does the side air bag system work?
The side air bag system consists of
the following:
•An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•A special seat cover designed to
allow airbag deployment.
•The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
•Two 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.
