GMC 2007 Acadia - Manual (Page 81)

{ 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 use seat accessories that block
the inflation path of a seat-mounted side
impact airbag.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening. If
you do, the path of an inflating roof-rail
airbag will be blocked.
When Should an Airbag Inflate?
Frontal airbags are designed to inflate in moderate
to severe frontal or near-frontal crashes to help
reduce the potential for severe injuries mainly
to the driver’s or right front passenger’s head and
chest. However, they are only designed to
inflate if the impact exceeds a predetermined
deployment threshold. Deployment thresholds 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.
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.
