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 the servicing vehicle
and 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 occupants in the
center front seating position.
Seating and Safety Restraints
120

Steps you can take to properly position yourself
away from the air bag:
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 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.
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 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. Air bags are
designed to inflate in frontal and near-frontal collisions,
Seating and Safety Restraints

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.
The SRS consists of:
²driver and passenger air bag modules (which
include the inflators and air bags)
²one or more impact and safing sensors
²a readiness light and tone
²a diagnostic module
²and the electrical wiring which connects the
components

The diagnostic module monitors its own internal
circuits and the supplemental air bag electrical
system warning (including the impact sensors), the
system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors.
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.
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 toAir bag readinesssection in the
Instrument clusterchapter. Routine maintenance of
the air bag is not required.
A difficulty with the system is indicated by one or
more of the following:
²The readiness light
will either flash or
stay lit.
²The readiness 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/or light are repaired.
If any of these things happen, even intermittently,
have the SRS serviced at your dealership or by a
qualified technician immediately. Unless serviced,
the system may not function properly in the event of
a collision.

stopping distance. Always leave enough room
between your vehicle and the vehicle in front of
you to stop.
²We recommend that you familiarize yourself with
this braking technique. However, avoid taking any
unnecessary risks.
Hydraulic brake booster system (Hydroboost)
The Hydroboost system receives fluid pressure from
the power steering pump to provide power assist
during braking.
The sound of the pump operating may be heard by
the driver, but this is a normal characteristic of the
system.
For Hydroboost-equipped vehicles operating under
normal conditions, the noise of the fluid flowing
through the booster may be heard whenever the
brake is applied. This condition is normal. Vehicle
service is not required.
If braking performance or pedal response becomes
very poor, even when the pedal is strongly
depressed, it may indicate the presence of air in the
hydraulic system or leakage of fluid. Stop the vehicle
safely as soon as possible and seek service
immediately.
TRACTION CONTROLY
Your vehicle may be equipped with the optional
Traction Controlysystem. This system helps you
maintain the stability and steerability of your
vehicle. It is especially useful on slippery 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 rear 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 rear brakes in conjunction with engine torque
