Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on theseat during vehicle maneuvers and braking, whichhelps the passenger sensing system maintain thepassenger airbag status. See “Safety Belts” and“Child Restraints” in the Index for additional informationabout the importance of proper restraint use.
A thick layer of additional material, such as a blanket orcushion, or aftermarket equipment such as seatcovers, seat heaters, and seat massagers can affecthow well the passenger sensing system operates.We recommend that you not use seat covers or otheraftermarket equipment except when approved by GM foryour specific vehicle. SeeAdding Equipment to YourAirbag-Equipped Vehicle on page 2-73for moreinformation about modifications that can affect how thesystem operates.
{WARNING:
Stowing of articles under the passenger seat or
between the passenger seat cushion and seatback
may interfere with the proper operation of the
passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.There are parts of the airbag system in several placesaround the vehicle. Your dealer/retailer and theservice manual have information about servicing thevehicle and the airbag system. To purchase a servicemanual, seeService Publications Ordering Informationon page 8-17.
{WARNING:
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.
