Seats and Restraints
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts.
If the GVWR (Gross Vehicle Weight
Rating) of your vehicle is 3 855 kg
(8,500 lb) or above, the vehicle has
single stage airbags. If the GVWR is
below 3 855 kg (8,500 lb) then the
vehicle has dual stage airbags.
Vehicles with a full bench seat are
equipped with single state airbags.
You can find the GVWR on the
certification label on the rear edge
of the driver door. See

for more
information.
The vehicle may have 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.
Vehicles with dual stage airbags
also have a seat position sensor
which enables the sensing system
to monitor the position of the driver
seat and the front outboard
passenger seat on light-duty models
only. The seat position sensor
provides information that is used to
determine if the airbags should
deploy at a reduced level or at full
deployment.
The vehicle may have seat-mounted
side impact airbags. The vehicle
may have 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. 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 deploy on the side of
the vehicle that is struck. 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,
or in a severe frontal impact.
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
seat-mounted side impact and
roof-rail airbags, deployment is
determined by the location and
severity of the side impact. In a
