Cadillac 2003 Seville Owner's Manual page 54

The right front passenger's side impact air bag is in the
side of the passenger's seatback closest to the door.
If something is between an occupant and an
air bag, the bag might not inflate properly ~r it
might force the object into that person causing
severe injury or even death. The path of an
inflating air bag must be kept clear. Don't put
anything between an occupant and an air bag,
and don't attach or put anything on the
steering wheel hub or on or near any other air
bag covering. Don't let seat covers block the
inflation path of a side impact air bag.
When Should an Air Bag Inflate?
The driver's and right front passenger's frontal air bags
are designed to inflate in moderate to severe frontal
or near-irontai crashes. But they are designed to inflate
only if the impact speed is above the system's
designed "threshold level".
If your vehicle goes straight into a wall that doesn't
move or deform, the threshold level is about 9 to 15 mph
(14 te 24 kmk). The threshold ledel c m vary., however,
with specific vehicle design, so that it can be somewhat
above or below this range.
