Seats and Restraints

Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
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, 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.

The vehicle has seat-mounted side
impact airbags and roof-rail airbags.
See

Airbag System on page 3

.

Seat-mounted side impact and
roof-rail airbags are intended to
inflate in moderate to severe side
crashes depending on the location
of the impact. 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 on
its side, 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. The inflator, the airbag,
and related hardware are all part of
the airbag module.

the Airbags? on page 3

  • 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 on its side, 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?
  • The inflator, the airbag, and related hardware are all part of the airbag module. For airbag location, see Where Are the Airbags?
