Cadillac 2006 XLR - Manual (Page 42)

The passenger’s side impact airbag is in the side of the
passenger’s 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.
