I was stopped at a stoplight and the car ahead of me moved up slightly so I took my foot off the brake. I did not accelerate by pressing the gas pedal and I was going approximately 1-2 MPH. Car in front of me slammed on their brakes and I tried to depress my brake and the brake alert signal inside the car started flashing, but it was a delayed reaction and the air bags in the steering wheel and below my feet by my legs deployed as I braked. There was no damage to the other car and a bumper gap occurred on my car and the air bags deployed and seatbelts locked in my vehicle. I barely touched the other car. Air bags malfunctioned by deploying at no real impact, air bag cut my hand, seatbelts were all replaced in vehicle, air bags replaced, bumper replaced, air bag sensor replaced.
