When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate 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.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors
which help the sensing system distinguish between a
moderate and a more severe frontal impact.
For moderate frontal impacts, these airbags inate at a
level less than full deployment. For more severe
frontal impacts, full deployment occurs. If the front of
your vehicle goes straight into a wall that doesn’t move
or deform, the threshold level for the reduced
deployment is about 12 to 16 mph (19.3 to 26 km/h),and the threshold level for a full deployment is about
20 to 24 mph (32.2 to 38.5 km/h). (The threshold
level can vary, however, with specic vehicle design, so
that it can be somewhat above or below this range.)
Airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at a
different crash speed than if the object does not
deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate 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
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts because ination
would not likely help the occupants.

If your vehicle has side impact airbags, it has electronic
side sensors. The side impact airbags are designed
to inate in moderate to severe side crashes. A side
impact airbag will inate if the crash severity is above
the system’s designed “threshold level”. The threshold
level can vary with specic vehicle design. Side impact
airbags are not designed to inate in frontal or
near-frontal impacts, rollovers or rear impacts, because
ination would not likely help the occupant. A side
impact airbag will only deploy on the side of the vehicle
that is struck.
Your vehicle has seat position sensors which enable the
sensing system to monitor the position of the driver’s
seat and the right front passenger’s seat. Seat position
sensors provide information that is used to determine
if the airbags should deploy at a reduced level or
at full deployment.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
the angle of the impact and how quickly the vehicle
slows down in frontal or near-frontal impacts. For side
impact airbags, ination is determined by the location
and severity of the impact.What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact airbags, the sensing system
triggers a release of gas from the inator, which inates
the airbag. The inator, airbag, and related hardware
are all part of the airbag modules inside the steering
wheel and in the instrument panel in front of the
right front passenger. For vehicles with side impact
airbags, the airbag modules are located in the ceiling of
the vehicle, near the side windows.
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. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal airbags would not help you in many types
of collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion
is not toward the airbag. Side impact airbags would not
help you in many types of collisions, including frontal
