Buick 2007 Rainier - Manual (Page 73)

If your vehicle has a roof-mounted airbag for the
right front passenger and the person directly
behind that passenger, it is located in the ceiling
above the side windows.
{ CAUTION:
If something is between an occupant
and an airbag, the bag 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. And, if your vehicle
has roof-mounted side impact 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 side
impact airbag will be blocked. The path
of an inflating airbag must be kept clear.
