When starting my 1995 C280, the SRS light comes on and stays illuminated for about 1 minute. The manual indicates it should go off after about 4 seconds but also indicates that if there is a problem, the indicator stays lit and may even come on while you are driving (which it does not once it goes out). When I start the car I hear a relay clicking sound that seems to be coming from the passenger side footwell area. This just started happening yesterday and I am not sure if this is a problem or may end up being something that turns out to be intermittent. Anyone have any idea on what could be causing this behavior?
