When Should an Airbag Inflate?
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.
Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has a seat position sensor which enables
the sensing system to monitor the position of the right
front passenger’s seat. The passenger seat position
sensor and passenger safety belt buckle switch 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 a dual-stage driver airbag.
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.
Your vehicle also has a dual-depth passenger airbag that
adjusts the restraint according to crash severity, seat
location, and safety belt status using electronic frontal
sensor(s) and other special sensors which enable the
sensing system to monitor the position of the front
passenger seat. The passenger airbag inflates to a
reduced depth when the passenger seat is in a forward
position. For more rearward front seating positions,
the passenger airbag may inflate to an increased depth
(a full deployment), based on safety belt status and the
crash severity measured early in the event. (Always wear
your safety belt, even with frontal airbags.)
