Saturn 2009 VUE Hybrid - Manual (Page 50)

Frontal airbags may inflate at
different crash speeds. For example:
• If the vehicle hits a stationary
object, the airbags could inflate at
a different crash speed than if the
vehicle hits a moving object.
• If the vehicle hits an object that
deforms, the airbags could inflate
at a different crash speed than if
the vehicle hits an object that
does not deform.
• If the vehicle hits a narrow object
(like a pole), the airbags could
inflate at a different crash speed
than if the vehicle hits a wide
object (like a wall).
• If the vehicle goes into an object
at an angle, the airbags could
inflate at a different crash speed
than if the vehicle goes straight
into the object.
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 and roof-rail airbags. See
Airbag System on page 1-41.
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.
Seat-mounted side impact airbags
are not intended to inflate in
frontal impacts, near-frontal impacts,
rollovers, or rear impacts. 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
