LINCOLN LS 2000 Owners Manual

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.
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
Seating and safety restraints
131

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 is inflated,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 theInstrumentationchapter. 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 to the RUN
position.
Seating and safety restraints
132

²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and 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.
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
Supplemental Restraint System, 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 including the driver 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:
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 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.

Several air bag system
components get hot after
inflation. Do not touch them after
inflation.
If the side air bag has
deployed,the air bag will
not function again. The side
air bag system (including the
seat) must be inspected and
serviced by a qualified
technician in accordance with
the vehicle service manual.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 to theAir bag readiness
section in theInstrumentationchapter. 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 (same light as used for front air bag system) 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 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.

Disposal of air bags and air bag equipped vehicles (including
pretensioners)
For disposal of air bags or air bag equipped vehicles, see your local
dealership or qualified technician. Air bags MUST BE disposed of by
qualified personnel.
SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAir Bag Supplemental Restraint
System (SRS)in this chapter for special instructions about using air
bags.
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children ride in your vehicle (generally children who
are four years old or younger and who weigh 18 kg [40 lbs] or less), you
must put them in safety seats made especially for children. Check your
local and state or provincial laws for specific requirements regarding the
safety of children in your vehicle.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.
When possible, always place children under age 12 in the rear seat of
your vehicle. Accident statistics suggest that children are safer when
properly restrained in the rear seating positions than in the front seating
position.
Children and safety belts
If the child is the proper size, restrain the child in a safety seat.
Children who are too large for child safety seats (as specified by your
child safety seat manufacturer) should always wear safety belts.
Follow all the important safety restraint and air bag precautions that
apply to adult passengers in your vehicle.
If the shoulder belt portion of a combination lap and shoulder belt can
be positioned so it does not cross or rest in front of the child's face or
Seating and safety restraints
136

neck, the child should wear the lap and shoulder belt. Moving the child
closer to the center of the vehicle may help provide a good shoulder belt
fit.
Do not leave children, unreliable adults, or pets unattended in
your vehicle.
To improve the fit of lap and shoulder belts on children who have
outgrown child safety seats, Ford recommends use of a belt-positioning
booster seat that is labelled as conforming to all Federal motor vehicle
safety standards. Belt-positioning booster seats raise the child and
provide a shorter, firmer seating cushion that encourages safer seating
posture and better fit of lap and shoulder belts on the child.
A belt-positioning booster should be used if the shoulder belt rests in
front of the child's face or neck, or if the lap belt does not fit snugly on
both thighs, or if the thighs are too short to let the child sit all the way
back on the seat cushion when the lower legs hang over the edge of the
seat cushion. You may wish to discuss the special needs of your child
with your pediatrician.
SAFETY SEATS FOR CHILDREN
Child and infant or child safety seats
Use a safety seat that is recommended for the size and weight of the
child. Carefully follow all of the manufacturer's instructions with the
safety seat you put in your vehicle. If you do not install and use the
safety seat properly, the child may be injured in a sudden stop or
collision.
Seating and safety restraints
137

When installing a child safety seat:
²Review and follow the information
presented in theAir Bag
Supplemental Restraint System
section in this chapter.
²Use the correct safety belt buckle
for that seating position.
²Insert the belt tongue into the
proper buckle until you hear a
snap and feel it latch. Make sure
the tongue is securely fastened in
the buckle.
²Keep the buckle release button pointing up and away from the safety
seat, with the tongue between the child seat and the release button,
to prevent accidental unbuckling.
²Place seat back in upright position.
²Put the safety belt in the automatic locking mode. Refer toAutomatic
locking mode.
Ford recommends the use of a child safety seat having a top tether
strap. Install the child safety seat in a seating position which is capable
of providing a tether anchorage. For more information on top tether
straps, refer toAttaching safety seats with tether straps.
Carefully follow all of the manufacturer's instructions included
with the safety seat you put in your vehicle. If you do not install
and use the safety seat properly, the child may be injured in a sudden
stop or collision.

Installing child safety seats in combination lap and shoulder belt
seating positions
1. Position the child safety seat in a
seat with a combination lap and
shoulder belt.
An air bag can kill or injure a child in a child seat. If you must
use a forward-facing child seat in the front seat, move seat all
the way back.
Children 12 and under should be properly restrained in the rear
seat whenever possible.
2. Pull down on the shoulder belt
and then grasp the shoulder belt
and lap belt together.
Seating and safety restraints
139

3. While holding the shoulder and
lap belt portions together, route the
tongue through the child seat
according to the child seat
manufacturer's instructions. Be sure
the belt webbing is not twisted.
4. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) for that seating position until
you hear a snap and feel the latch
engage. Make sure the tongue is
latched securely by pulling on it.
5. To put the retractor in the
automatic locking mode, grasp the
shoulder portion of the belt and pull
downward until all of the belt is
extracted and a click is heard.
6. Allow the belt to retract. The belt will click as it retracts to indicate it
is in the automatic locking mode.
