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.

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.

•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.
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, 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:
•driver and passenger air bag modules (which
include the inflators and air bags)
•one or more impact and safing sensors
•a readiness light and tone
•a 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 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.

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 Control
portion of the
ABS computer. Any excessive wheel spin is
controlled by automatically applying and releasing
the rear 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 rear wheels“search”for
optimum traction several times a second and
adjustments are made accordingly.
The Traction Control
system 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.
During Traction
Control
operation,
the traction control
active light will
illuminate, you may hear an electric motor type of
sound coming from the engine compartment and the
engine will not“rev-up”when you push further on
the accelerator. This is normal system behavior.
The Traction Control

on/off switch, located
below the radio,
illuminates when the
system is OFF. The
Traction Control
system will revert to the ON
position every time the ignition is turned OFF and
ON.
If you should become stuck in snow or ice or on a
very slippery road surface, try switching the Traction
Control
system off. This may allow excess wheel
spin to“dig”the vehicle out and enable a successful
“rocking”maneuver.
