On one of my cars, the "airbag" warning light will not illuminate. The car has never been crashed at all. Owners manual states it could be a bad bulb. Since the light is stated to only be on for 6 seconds after ignition is turned on, I do not think it is the bulb. If the fuse had blown, could this cause the light itself to not illuminate? Does anyone have a airbag equipped Mercedes, that the "airbag" or "SRS" light does not illuminate on? Thanks.
