GM Service Manual Online
For 1990-2009 cars only

Airbags affect how your vehicle should be serviced. There are parts of the airbag system in several places around your vehicle. Your dealer and the service manual have information about servicing your vehicle and the airbag system.

Caution: For up to 10 seconds after the ignition is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. Avoid yellow connectors. They are probably part of the airbag system. Be sure to follow proper service procedures, and make sure the person performing work for you is qualified to do so.

The airbag system do not need regular maintenance.
