When Should an Airbag In?ate?
Frontal airbags are designed to in?ate 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 in?ate 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 in?ate 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 in?ate at different crash speeds.
For example:
? If the vehicle hits a stationary object, the airbags
could in?ate at a different crash speed than if the
vehicle hits a moving object.
? If the vehicle hits an object that deforms, the
airbags could in?ate 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 in?ate 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 in?ate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with speci?c vehicle design.
Frontal airbags are not intended to in?ate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has seat position sensors which enables
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 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 in?ate at a level less than full deployment.
For more severe frontal impacts, full deployment occurs.
