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 curtains (if equipped). Refer toSide air curtain 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 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.
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 theInstrument clusterchapter. 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 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 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.
Safety Canopy
system (if equipped)
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.
Seating and safety restraints

Do not lean your head on the door. The Safety Canopycould
injure you as it deploys from the headliner.
Do not attempt to service, repair, or modify the Safety Canopy
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy. 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 and Safety
Canopysystem is provided.
To reduce risk of injury, do not obstruct or place objects in the
deployment path of the inflatable Safety Canopy.
How does the Safety Canopy
system work?
The design and development of the
Safety Canopysystem included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy).
The Safety Canopysystem
consists of the following:
•An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one each side of the vehicle).
•The headliner will flex to open above the side doors to allow Safety
Canopydeployment.
Seating and safety restraints
155

•The same warning light, electronic control and diagnostic unit as used
for the front airbags.
•Two side crash sensors mounted at the base of the B-pillar (one on
each side).
•Two side crash sensors located at the c-pillar behind the rear doors
(one on each side).
•Roll over sensor in the restraints control module (RCM).
The Safety Canopysystem, in combination with seat belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats (if equipped). The Safety Canopywill
not interfere with children restrained using a properly installed child or
booster seat because it is designed to inflate downward from the
headliner above the doors along the side window openings.
The Safety Canopysystem is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopyinflation or when
a certain likelihood of a rollover event is detected by the rollover sensor.
The Safety Canopyis mounted to the roof side-rail sheet metal, behind
the headliner, above the first and second row seats. In certain lateral
collisions or rollover events, the Safety Canopysystem will be
activated, regardless of which seats are occupied. The Safety Canopyis
designed to inflate between the side window area and occupants to
further enhance protection provided in side impact collisions and rollover
events.
The fact that the Safety Canopysystem 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. The
Safety Canopyis designed to inflate in certain side impact collisions or
rollover events, not in rear impact, frontal or near-frontal collisions,
unless the collision causes sufficient lateral deceleration or rollover
likelihood.

Several Safety Canopy
system components get hot
after inflation. Do not touch them
after inflation.
If the Safety Canopysystem has deployed,the Safety
Canopywill not function again. The Safety Canopy
system (including the A, B and C pillar trim) must be inspected
and serviced by a qualified technician in accordance with the
vehicle service manual.If the Safety Canopyis 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:
•The readiness light (same light as for front 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 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
or rollover event.
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 positions.
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
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.

Childboosterseats
Childrenoutgrowatypicalconvertibleortoddlerseatwhentheyweigh
40 pounds and are around 4 years of age. Although the lap/shoulder belt
will provide some protection, these children are still too small for
lap/shoulder belts to fit properly, which could increase the risk of serious
injury.
To improve the fit of both the lap and shoulder belt on children who
have outgrown child safety seats, Ford Motor Company recommends use
of a belt-positioning booster.
Booster seats position a child so that safety belts fit better. They lift the
child up so that the lap belt rests low across the hips and the knees
bend comfortably. Booster seats also make the shoulder belt fit better
and more comfortably for growing children.
When children should use booster seats
Children need to use booster seats from the time they outgrow the
toddler seat until they are big enough for the vehicle seat and
lap/shoulder belt to fit properly. Generally this is when they weigh about
80 lbs (about 8 to 12 years old).
Booster seats should be used until you can answer YES to ALL of these
questions:
•Can the child sit all the way back
against the vehicle seat back with
knees bent comfortably at the
edge of the seat without
slouching?
•Does the lap belt rest low across the hips?
•Is the shoulder belt centered on the shoulder and chest?
•Can the child stay seated like this for the whole trip?

Types of booster seats
There are two types of belt-positioning booster seats:
•Those that are backless.
If your backless booster seat has a
removable shield, remove the
shield and use the lap/shoulder
belt. If a seating position has a
low seat back and no head
restraint, a backless booster seat
may place your child’s head (top
of ear level) above the top of the
seat. In this case, move the
backless booster to another
seating position with a higher seat back and lap/shoulder belts.
•Those with a high back.
If, with a backless booster seat,
you cannot find a seating position
that adequately supports your
child’s head, a high back booster
seat would be a better choice.
Both can be used in any vehicle in a seating position equipped with
lap/shoulder belts if your child is over 40 lbs.
The shoulder belt should cross the chest, resting snugly on the center of
the shoulder. The lap belt should rest low and snug across the hips,
never up high across the stomach.
If the booster seat slides on the vehicle seat, placing a rubberized mesh
sold as shelf or carpet liner under the booster seat may improve this
condition.
The importance of shoulder belts
Using a booster without a shoulder belt increases the risk of a child’s
head hitting a hard surface in a collision. For this reason, you should
never use a booster seat with a lap belt only. It is best to use a booster
seat with lap/shoulder belts in the back seat- the safest place for children
to ride.
