When Should An Airbag Inflate - GMC Sierra 2005 Owner's Manual

When Should an Airbag Inflate?
The driver's and right front passenger's frontal airbags
are designed to inflate in moderate to severe frontal
or near-frontal crashes. But they are designed to inflate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inflate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
Airbags may inflate at different crash speeds. For
example:
•
If the vehicle hits a stationary object, the airbag
could inflate at a different crash speed than if
the object were moving.
•
If the object deforms, the airbag could inflate at a
different crash speed than if the object does not
deform.
•
If the vehicle hits a narrow object (like a pole) the
airbag 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
airbag could inflate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger)
are not intended to inflate during vehicle rollovers, rear
impacts, or in many side impacts because inflation
would not likely help the occupants.
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. Inflation is determined by the angle of the
impact and how quickly the vehicle slows down in
frontal or near-frontal impacts.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See Off-Road
Driving with Your Four-Wheel-Drive Vehicle on
