Chevrolet 2010 HHR Automobile User Manual


 
In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has an electronic frontal
sensor, which helps 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 may or may not have roof-rail airbags.
See Airbag System
on page 260
. 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. 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 frontal
impacts, near-frontal impacts, or rear impacts.
A roof-rail airbag is intended to deploy on the side
of the vehicle that is struck or if the sensing system
predicts that the vehicle is about to roll over.
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 roof-rail
airbags, deployment is determined by the location and
severity of the side impact. In a rollover event, roof-rail
airbag deployment is determined by the direction of
the roll.
