Hummer 2007 H3 - Manual (Page 72)

If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold
level for the reduced deployment is about 11 to
18 mph (17.5 to 28.9 km/h), and the threshold
level for a full deployment is about 18 to 23 mph
(28.9 to 37 km/h). The threshold level can
vary, however, with specific vehicle design, so that
it can be somewhat above or below this range.
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.
Frontal airbags (driver and right front passenger)
are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has seat position sensors which
enable the sensing system to monitor the position
of the driver’s seat and the right front passenger’s
seat. Seat position sensors provide information
that is used to determine if the airbags should
deploy at a reduced level or at full deployment.
Your vehicle may or may not have roof-mounted
side impact airbags and a rollover sensor.
See Airbag System on page 65. These “rollover
capable” airbags are intended to inflate in
moderate to severe side crashes or during a
rollover. A roof-mounted 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. Roof-mounted side impact airbags are
not intended to inflate in rear impacts. Both
roof-mounted rollover airbags will deploy when
either side of the vehicle is struck or during
a rollover.
