2010 GMC Sierra 1500 Crew Cab Owner's Manual - Page 124

The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps and hazard warning flashers, and shut off the fuel system after the airbags inflate. You can lock the doors, turn off the interior lamps and hazard warning flashers by using the controls for those features. In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the right front passenger airbag. . { WARNING: A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the fuel system, brake and steering systems, etc. Even if the vehicle appears to be drivable after a moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle. Use caution if you should attempt to restart the engine after a crash has occurred. . Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for your vehicle covers the need to replace other parts. The vehicle has a crash sensing and diagnostic module which records information after a crash. See Vehicle Data Recording and Privacy on page 8‑19 and Event Data Recorders on page 8‑20. Let only qualified technicians work on the airbag systems. Improper service can mean that an airbag system will not work properly. See your dealer for service. . 2-82
