Buick 2007 Rendezvous - Manual (Page 95)

Your vehicle may or may not have side impact
airbags. See Airbag System on page 88 for more
information. Side impact airbags are intended
to inflate in moderate to severe side crashes. A
side impact airbag will inflate if the crash severity
is above the system’s designed “threshold
level.” The threshold level can vary with specific
vehicle design. Side impact airbags are not
intended to inflate in frontal or near-frontal impacts,
rollovers, or rear impacts. A side impact airbag
is intended to deploy on the side of the vehicle that
is struck.
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 side impact airbags, inflation is
determined by the location and severity of the
impact.
What Makes an Airbag Inflate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is
in a crash. The sensing system triggers a release
of gas from the inflator, which inflates the
airbag. The inflator, the airbag and related
hardware are all part of the airbag modules.
Frontal airbag modules are located inside
the steering wheel and instrument panel. For
seating positions with side impact airbags, there
are also airbag modules in the side of the
seatbacks closest to the door.
