PRINCIPLE OF OPERATION
WARNING: Airbags do not inflate
slowly or gently, and the risk of injury from
a deploying airbag is the greatest close to
the trim covering the airbag module. WARNING:
All occupants of your
vehicle, including the driver, should always
properly wear their seatbelts, even when
an airbag supplemental restraint system
is provided. Failure to properly wear your
seatbelt could seriously increase the risk
of injury or death. WARNING:
Even with advanced
restraints systems, properly restrain
children 12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or death. WARNING:
Do not place your arms
on the airbag cover or through the steering
wheel. Failure to follow this instruction
could result in personal injury. WARNING:
Keep the areas in front
of the airbags free from obstruction. Do
not affix anything to or over the airbag
covers. Objects could become projectiles
during airbag deployment or in a sudden
stop. Failure to follow this instruction could
result in personal injury or death. WARNING:
Airbags can kill or injure
a child in a child restraint. Never place a
rear-facing child restraint in front of an
active airbag. If you must use a
forward-facing child restraint in the front
seat, move the seat upon which the child
restraint is installed all the way back. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to follow
this instruction could result in personal
injury or death. WARNING:
Several airbag system
components get hot after inflation. To
reduce the risk of injury, do not touch them
after inflation. WARNING:
If a supplementary
restraint system component has deployed,
it will not function again. Have the system
and associated components inspected as
soon as possible. Failure to follow this
instruction could result in personal injury
or death.
The airbags are a supplemental restraint
system and are designed to work with the
seatbelts to help protect the driver and
right front passenger from certain upper
body injuries. Airbags do not inflate slowly;
there is a risk of injury from a deploying
airbag.
Note: You will hear a loud bang and see a
cloud of harmless powdery residue if an
airbag deploys. This is normal.
The airbags inflate and deflate rapidly
upon activation. After airbag 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 (for example, baking soda)
that result from the combustion process
that inflates the airbag. Small amounts of
sodium hydroxide may be present which
may irritate the skin and eyes, but none of
the residue is toxic.

•
Wait at least two minutes and verify
that the airbag readiness light is no
longer illuminated.
• If the airbag readiness light remains
illuminated, this may or may not be a
problem due to the front passenger
sensing system.
Do not attempt to repair or service the
system. Take your vehicle immediately to
an authorized dealer.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact the Ford
Customer Relationship Center. See
Getting the Services You Need (page
165).
SIDE AIRBAGS WARNING:
Do not place objects or
mount equipment on or near the airbag
cover, on the side of the seatbacks (of the
front seats), or in front seat areas that may
come into contact with a deploying airbag.
Failure to follow these instructions may
increase the risk of personal injury in the
event of a crash. WARNING:
Do not use accessory
seat covers. The use of accessory seat
covers may prevent the deployment of the
side airbags and increase the risk of injury
in an accident. WARNING:
Do not lean your head
on the door. The side airbag could injure
you as it deploys from the side of the
seatback. WARNING:
Do not attempt to
service, repair, or modify the airbag, its
fuses or the seat cover on a seat containing
an airbag as you could be seriously injured
or killed. Contact your authorized dealer
as soon as possible. WARNING:
If the side airbag has
deployed, the airbag will not function
again. The side airbag system (including
the seat) must be inspected and serviced
by an authorized dealer. If the airbag is not
replaced, the unrepaired area will increase
the risk of injury in a crash.
The side airbags are located on the
outboard side of the seatbacks of the front
seats. In certain sideways crashes, the
airbag on the side affected by the crash
will be inflated. The airbag was designed
to inflate between the door panel and
occupant to further enhance the protection
provided occupants in side impact crashes. The system consists of the following:
•
A label or embossed side panel
indicating that side airbags are fitted
to your vehicle.
• Side airbags located inside the driver
and front passenger seatbacks.
• Front passenger sensing system.

•
Crash sensors and monitoring system
with readiness indicator. See Crash
Sensors and Airbag Indicator (page
43
).
Note: The passenger sensing system will
deactivate the passenger seat-mounted
side airbag if it detects an empty passenger
seat.
The design and development of the side
airbag system 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.
DRIVER KNEE AIRBAG
A driver ’s knee airbag is located under or
within the instrument panel. During a crash,
the restraints control module may activate
the driver ’s knee airbag based on crash
severity and occupant conditions. Under
certain crash and occupant conditions, the
driver ’s knee airbag may deploy but the
driver ’s front airbag may not activate. As
with front and side airbags, it is important
to be properly seated and restrained to
reduce the risk of death or serious injury. Make sure the knee airbag is
operating properly. See
Crash
Sensors and Airbag Indicator
(page
43). SAFETY CANOPY™ WARNING:
Do not place objects or
mount equipment on or near the headliner
at the siderail that may come into contact
with a deploying curtain airbag. Failure to
follow these instructions may increase the
risk of personal injury in the event of a
crash. WARNING:
Do not lean your head
on the door. The curtain airbag could injure
you as it deploys from the headliner. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to follow
this instruction could result in personal
injury or death. WARNING:
All occupants of your
vehicle, including the driver, should always
properly wear their seatbelts, even when
an airbag supplemental restraint system
is provided. Failure to properly wear your
seatbelt could seriously increase the risk
of injury or death. WARNING:
To reduce risk of injury,
do not obstruct or place objects in the
deployment path of the airbag. WARNING:
If a supplementary
restraint system component has deployed,
it will not function again. Have the system
and associated components inspected as
soon as possible. Failure to follow this
instruction could result in personal injury
or death.

The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. A warning indicator light in the
instrument cluster indicates the readiness
of the safety system. If this warning
indicator light is not functioning and there
is another fault within the system, the
message cluster could display an airbag
failure warning. A tone sounds, a warning
indicator light illuminates, or both, until the
problem is repaired. Routine maintenance
of the airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
The indicator light will not
illuminate immediately after you
switch the ignition on.
• The indicator light either flashes or
stays illuminated.
• You could hear five tones that
periodically repeat until the problem is
repaired.
• A message could appear in the
information display.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The seatbelt pretensioners and the airbag
supplemental restraint system are
designed to activate when your vehicle
sustains frontal or sideways deceleration
sufficient to cause the restraints control
module to deploy a safety device or when
a certain likelihood of a rollover event is
detected by the rollover sensor. The fact that the seatbelt pretensioners
or airbags did not activate for both front
seat occupants in a crash does not mean
that something is wrong with the system.
Rather, it means the restraints control
module determined the crash conditions
(for example, crash severity, belt usage)
were not appropriate to activate these
safety devices.
•
The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts) unless the crash causes
sufficient frontal deceleration.
• The seatbelt pretensioners are
designed to activate in frontal,
near-frontal, side and rollover crashes.
• The design of the side airbags is to
inflate in certain side crashes. Side
airbags could activate in other types of
crashes if the vehicle experiences
sufficient sideways motion or
deformation.
• The knee airbag(s) could deploy based
on crash severity and occupant
conditions.
• The design of the Safety Canopy is to
inflate in certain side impact crashes
and when a certain likelihood of
rollover is detected by the rollover
sensor. The Safety Canopy could
activate in other types of crashes if the
vehicle experiences sufficient sideways
motion or deformation, or a certain
likelihood of rollover.
AIRBAG DISPOSAL
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.
