When Should an Airbag Inflate?
The driver’s and right front passenger’s frontal airbags
are designed to inflate in moderate to severe frontal
or near-frontal crashes. But they are designed to inflate
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 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.
Your vehicle has a “dual stage” driver airbag, which
adjusts the restraint according to crash severity using
electronic frontal sensor(s) which help the sensing
system distinguish between a moderate frontal impact
and a more severe frontal impact. The “dual stage”
driver airbag inflates to a level less than full deployment
for moderate frontal impacts and to a full deployment
for more severe frontal impacts.
Your vehicle is also equipped with 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 status of the front passenger safety belt and
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.)
If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold level
for the reduced deployment is about 12 to 16 mph
(19 to 26 km/h), and the threshold level for a full
deployment is about 17 to 22 mph (27 to 35 km/h)
if the other sensors do not over-ride this. The threshold
level can vary, however, with specific vehicle design,
so that it can be somewhat above or below this range.
