GMC 2005 Yukon - When Should an Airbag Inflate

{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inflate properly or
it might force the object into that person
causing severe injury or even death. The path
of an inflating airbag must be kept clear.
Do not put anything between an occupant and
an airbag, and do not attach or put anything
on the steering wheel hub or on or near any
other airbag covering. Do not let seat covers
block the inflation path of a side impact airbag.
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.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors
which help the sensing system distinguish between a
moderate and a more severe frontal impact. For
moderate frontal impacts, these airbags inflate at a level
less than full deployment. For more severe frontal
impacts, full deployment occurs. 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 10 to 16 mph (16 to 25 km/h), and the
threshold level for a full deployment is about
20 to 30 mph (32 to 48 km/h). (The threshold level can
vary, however, with specific vehicle design, so that it can
be somewhat above or below this range.)
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.
