Buick 2010 Lucerne - Manual (Page 94)

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.
Your vehicle has a seat position sensor which enables
the sensing system to monitor the position of the right
front passenger's seat. The passenger seat position
sensor and passenger safety belt buckle switch provide
information that is used to determine if the airbags
should deploy at a reduced level or at full deployment.
In addition, your vehicle has a dual-stage driver airbag.
Dual-stage airbags adjust the restraint according to
crash severity. Your 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.
