Pontiac 2006 Montana SV6 Owner's Manual page 73

If your vehicle has a side impact airbag for the right
front passenger and/or the second row captain's
chairs (if equipped), it is in the side of the seatback
closest to the door.
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.
