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 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.
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.
Your vehicle may or may not have roof-rail airbags.
See Airbag System on page 1-56. Roof-rail airbags are
intended to inflate in moderate to severe side crashes.
In addition, these roof-rail airbags are intended to
inflate during a rollover. Roof-rail airbags will inflate if
the crash severity is above the system’s designed
threshold level. The threshold level can vary with
specific vehicle design.
Roof-rail airbags are not intended to inflate in frontal
impacts, near-frontal impacts, or rear impacts. Both
roof-rail airbags will deploy when either side of
the vehicle is struck or if the sensing system predicts
that the vehicle is about to roll over.
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 roof-rail airbags,
deployment is determined by the location and severity
of the side impact. In a rollover event, roof-rail airbag
deployment is determined by the direction of the roll.
