In addition, your vehicle has "dual stage" frontal
airbags, which adjust the restraint according to
crash severity. For moderate frontal impacts, these
airbags inflate at a level less than full deployment.
Your vehicle has electronic frontal sensors, which
help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For more severe frontal impacts, full
deployment occurs. 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 18 mph (19 to 29 km/h), and the
threshold level for a full deployment is about 18 to
25 mph (29 to 40.2 km/h). The threshold level can
vary, however, with specific vehicle design, so that
it can be somewhat above or below this range.

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.
The frontal airbags (driver and right front
passenger) are not intended to inflate during
vehicle rollovers, rear impacts, or in many side
impacts.
