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.)
Your vehicle has seat-mounted side impact and roof-rail
airbags. See Airbag System on page 2-62.
Seat-mounted side impact and roof-rail airbags are
intended to inflate in moderate to severe side crashes.
Seat-mounted side impact and 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.
