Cadillac 2006 - Manual (Page 60)

The roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger is in the ceiling above the side windows.
{ 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. 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 airbag will be
blocked. Do not let seat covers block the
inflation path of a side impact airbag. The path
of an inflating airbag must be kept clear.
