straight on or at an angle, and
whether the object is fixed or
moving, rigid or deformable,
narrow or wide.

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, the vehicle has
dual-stage frontal airbags.
Dual-stage airbags adjust the
restraint according to crash severity.
The vehicle has electronic frontal
sensors, that 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.

The vehicle has seat-mounted
side impact and roof-rail airbags.
See Airbag System on page 3‑21.

Seat-mounted side impact and
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 or in a severe
frontal impact. 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.

Roof-rail airbags are not
intended to inflate in rear impacts.
A seat-mounted side impact airbag
is intended to inflate on the side
of the vehicle that is struck. Both
roof-rail airbags will inflate when
either side of the vehicle is struck or
if the sensing system predicts that
the vehicle is about to roll over, or in
a severe frontal impact.

In any particular crash, no one can
say whether an airbag should have
inflated simply because of the
vehicle damage or repair costs.

What Makes an Airbag
Inflate?

In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover and deploy. The inflator,
the airbag, and related hardware are
all part of the airbag module.

Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat-mounted side impact airbags,
there are airbag modules in the side
of the front seatbacks closest to the
door. For vehicles with roof-rail
airbags, there are airbag modules in
the ceiling of the vehicle, near the
side windows that have occupant
seating positions.
