In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt.
The automatic locking mode is not available on the driver safety belt.
When to use the automatic locking mode
²Anytimea child safety seat is installed in the vehicle. Refer toSafety
Restraints for ChildrenorSafety Seats for Childrenlater in this
chapter.
How to disengage the automatic locking mode
Disconnect the combination lap/shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the seat belt system at all passenger
seating positions must be checked by a qualified technician to
verify that the ªautomatic locking retractorº feature for child seats is
still functioning properly, in addition to other checks for proper seat
belt system function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the seat belt assembly ªautomatic locking retractorº feature or
any other seat belt function is not operating properly. In addition, all
seat belts should be checked for proper function.
Failure to replace the belt and retractor assembly could increase
the risk of injury in collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front air bag supplemental restraint system
(SRS). When the safety belt pretensioner deploys, webbing from the lap
and shoulder belt is tightened. The driver and 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

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 in the servicing of your vehicle
and may help Ford better understand real world collisions and further
improve the safety of future vehicles.
Important supplemental restraint system (SRS) precautions
The supplemental restraint system
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 or
gently and the risk of injury from a
deploying air bag is greatest close to
the trim covering the air bag
module.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag SRS is
provided.
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.
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 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. 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 and turn the passenger air bag off. Refer toPassenger air
bag ON/OFF switchin this chapter of the owner's guide.
How does the safety belt pretensioner and air bag supplemental
restraint system work?
The safety belt pretensioner and air
bag SRS are designed to activate
when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates
pretensioner activation and air bag
inflation.
The fact that the pretensioners and
air bags did not activate 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 and
pretensioners are designed to activate in frontal and near-frontal
collisions, not rollover, side-impact, or rear-impacts unless the collision
causes sufficient longitudinal deceleration.
Seating and safety restraints
111

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:
²driver and passenger air bag modules (which include the inflators and
air bags)
²side air bags (if equipped). Refer toSide air bag systemlater in this
chapter
²safety belt pretensioners
²one or more impact and safing sensors

²a readiness light and tone
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, the air bag ignitors and safety belt pretensioners.
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 to theAir bag readiness
section in theInstrument clusterchapter. Routine maintenance of the
air bag is not required.
Any 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 to the RUN
position
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.

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 air bag 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 near 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.
