2003 GMC Sonoma Owner's Manual - Page 68

Air bags are designed to inflate only once. After they inflate, you'll need some new parts for your air bag system. If you don't get them, the air bag system won't be there to help protect you in another crash. A new system will include air bag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts. Your vehicle is equipped with a diagnostic module, which records information about the air bag system. The module records information about the readiness of the system, when the system commands air bag inflation and driver's safety belt usage at deployment. Let only qualified technicians work on your air bag system. Improper service can mean that an air bag system won't work properly. See your dealer for service. Air Bag Off Switch Regular Cab and Extended Cab Models Notice: If you damage the covering for the driver's or the right front passenger's airbag, the bag may not work properly. You may have to replace the air bag module in the steering wheel or both the air bag module and the instrument panel for the right front passenger's airbag. Do not open or break the air bag coverings. If your vehicle is a regular cab model or an extended cab model, it has a switch on the instrument panel that you can use to turn off the right front passenger's air bag. 1-61
