Warning Light On problems of the 2000 Mercedes Benz E320

While driving 55mph on a straight and level road, the passenger side curtain and right rear passenger door airbags deployed suddenly and without warning. The weather conditions were clear and dry. The road was asphalt and also dry. There were no other vehicles nearby and nothing in the road was run over. There was no contact with any objects whatsoever. There were no caution or warning lights prior to the event. The red "srs" light came on shortly after the air bags deployed.
