Section 17 (Air Bag Restraint System): Identification: Overview
WARNING: This page is about a different car, the 1994 GMC Safari and 1994 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
To avoid injury from accidental air bag deployment, read and carefully follow all WARNINGS and SERVICE PRECAUTIONS.
All models equipped with a Supplemental Inflatable Restraint (SIR) system have a number "2" (driver and passenger side air bags) or "3" (driver-side only air bag) in the seventh position of the Vehicle Identification Number (VIN). Some vehicles have the words Supplemental Inflatable Restraint or SIR on the inflator module. Steering wheel hub is slightly larger in order to accommodate the driver-side air bag.
