When Should an Airbag Inate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce
the potential for severe injuries mainly to the driver’s
or right front passenger’s head and chest. However,
they are only designed to inflate if the impact exceeds
a predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash
is likely to be in time for the airbags to inflate and help
restrain the occupants.
Whether your frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact,
and how quickly your vehicle slows down.Frontal airbags may inflate at different crash speeds.
For example:•If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
•If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed than
if the vehicle hits an object that does not deform.
•If the vehicle hits a narrow object (like a pole), the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
•If the vehicle goes into an object at an angle, the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
1-61

In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
Frontal airbags are not intended to inflate during
vehicle rollovers, rear impacts, or in many side impacts.
Your vehicle may or may not have seat-mounted
side impact airbags. SeeAirbag System on page 1-56.
Seat-mounted side impact airbags are intended
to inflate in moderate to severe side crashes.
Seat-mounted side impact airbags will inflate if the
crash severity is above the system’s designed
threshold level. The threshold level can vary with
specific vehicle design.Seat-mounted side impact airbags are not intended to
inflate in frontal impacts, near-frontal impacts, rollovers,
or rear impacts. A seat-mounted side impact airbag
is intended to deploy on the side of the vehicle that
is struck.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, inflation is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For seat-mounted
side impact airbags, deployment is determined by the
location and severity of the side impact.
1-62

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas from
the inflator. Gas from the inflator fills the airbag
causing the bag to break out of the cover and deploy.
The inflator, the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with seat-mounted side impact airbags, there are
airbag modules in the side of the front seatbacks
closest to the door.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Seat-mounted
side impact airbags distribute the force of the impact
more evenly over the occupant’s upper body.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-61for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
1-63

What Will You See After an
Airbag Inates?
After the frontal and seat-mounted side impact airbags
inflate, they quickly deflate, so quickly that some
people may not even realize the airbags inflated.
Some components of the airbag module may be hot
for several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-63.
The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in the
deflated airbags. Airbag inflation does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people
from leaving the vehicle.
{CAUTION:
When an airbag inates, there may be dust
in the air. This dust could cause breathing
problems for people with a history of asthma or
other breathing trouble. To avoid this, everyone
in the vehicle should get out as soon as it is
safe to do so. If you have breathing problems
but cannot get out of the vehicle after an airbag
inates, then get fresh air by opening a window
or a door. If you experience breathing problems
following an airbag deployment, you should
seek medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on, and turn on
the hazard warning flashers when the airbags inflate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning flashers off by using the
controls for those features.

In many crashes severe enough to inflate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from
the right front passenger airbag.
•Airbags are designed to inflate only once. After an
airbag inflates, you will need some new parts for
the airbag system. If you do not get them, the airbag
system will not be there to help protect you in
another crash. A new system will include airbag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
•Your vehicle has a crash sensing and diagnostic
module which records information after a crash.
SeeVehicle Data Recording and Privacy on
page 7-18andEvent Data Recorders on page 7-19.
•Let only qualified technicians work on the airbag
system. Improper service can mean that the
airbag system will not work properly. See your
dealer/retailer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system for the
right front passenger’s position. The passenger airbag
status indicator will be visible when you start your vehicle.
If you have a sedan, the airbag off symbol will be visible
near the clock, located in the center of the instrument
panel, during the system check. SeePassenger
Airbag Status Indicator (Sedan) on page 3-31. United States – Sedan
Canada – Sedan
1-65

If you have a hatchback, the airbag off symbol will be
visible in the Secondary Information Center (SIC) during
the system check. SeeSecondary Information Center
(SIC) (Hatchback Only) on page 3-43. When the system
check is complete, the airbag off symbol will be visible
under certain conditions.
The passenger sensing system will turn off the right
front passenger’s frontal airbag and seat-mounted side
impact airbag (if equipped) under certain conditions.
The driver’s airbags are not part of the passenger
sensing system.The passenger sensing system works with a sensor that
is part of the right front passenger’s seat. The sensor
is designed to detect the presence of a properly-seated
occupant and determine if the right front passenger’s
frontal airbag and seat-mounted side impact airbag
(if equipped) should be enabled (may inflate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front seat.
We recommend that children be secured in a rear
seat, including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on your sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys. United States –

{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal and seat-mounted side impact airbag
(if equipped) if the system detects a rear-facing
child restraint, no system is fail-safe, and no
one can guarantee that an airbag will not
deploy under some unusual circumstance,
even though it is turned off. We recommend
that rear-facing child restraints be secured in
a rear seat, even if the airbag(s) are off.
If you secure a forward-facing child restraint
in the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear seat.The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped) if:
•The right front passenger seat is unoccupied.
•The system determines that an infant is present in
a rear-facing infant seat.
•The system determines that a small child is present
in a child restraint.
•The system determines that a small child is present
in a booster seat.
•A right front passenger takes his/her weight off of
the seat for a period of time.
•The right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints.
•Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger’s frontal airbag and seat-mounted
side impact airbag (if equipped), the off symbol will
light and stay lit to remind you that the airbag or airbags
are off. SeePassenger Airbag Status Indicator
(Sedan) on page 3-31.
1-67

If a child restraint has been installed and the off
symbol is not lit, turn the vehicle off. Remove the
child restraint from the vehicle and reinstall the child
restraint following the child restraint manufacturer’s
directions and refer toSecuring a Child Restraint in
the Right Front Seat Position on page 1-52.
If, after reinstalling the child restraint and restarting the
vehicle, the off symbol is still not lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint
is not trapped under the vehicle head restraint.
If this happens, adjust the head restraint. SeeHead
Restraints on page 1-6.
Remove any additional material from the seat such
as blankets, cushions, seat covers, seat heaters,
or seat massagers before reinstalling or securing the
child restraint.
If the off symbol is still not lit, secure the child in the
child restraint in a rear seat position in the vehicle
and check with your dealer/retailer.The passenger sensing system is designed to enable
(may inflate) the right front passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped) anytime
the system senses that a person of adult size is sitting
properly in the right front passenger’s seat. When the
passenger sensing system has allowed the airbag or
airbags to be enabled, the off symbol will not light.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s
frontal airbag and seat-mounted side impact airbag
(if equipped), depending upon the person’s seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety
belt properly — whether or not there is an airbag for
that person.
If a person of adult-size is sitting in the right front
passenger’s seat, but the off symbol is lit, it could be
because that person is not sitting properly in the seat.
If this happens, turn the vehicle off, remove any additional
material from the seat, such as blankets, cushions,
seat covers, seat heaters or seat massagers and ask
the person to place the seatback in the fully upright
position, then sit upright in the seat, centered on the seat
cushion, with the person’s legs comfortably extended.
