For 1990-2009 cars

The driver’s frontal airbag is in the middle of the steering wheel.

The right front passenger’s airbag is in the instrument panel on the passenger’s side.

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.
