Warning Light On problems of the 2000 SAAB 9-3

I got into my parked vehicle as normal, closed the door and fastened my seatbelt. I then depressed the clutch pedal and inserted the key into the ignition. As I turned the key to start the car, the drivers seat side impact airbag deployed spontaneously causing temporary loss of hearing, a ringing sound in the ears, and injury to my left arm. I removed the key from the ignition and exited the vehicle. The vehicle was parked, and off/not running, in a parking lot at a local shopping mall. The vehicle was not hit, damaged, or used in any other way out of ordinary operation. There were no warning lights, sounds, or signs of disturbance in the airbag system. I went to the hospital shorter after to be treated for my injuries. The vehicle was then towed to its primary place of rest, my home.
