The RH group on most cars goes:
brake pads, brake hydraulics, parking brake, -empty-, airbag
On mine the "empty" has a symbol which looks a bit like a heater element. Anyone any idea what it might be? The car is not a diesel of course - and the light is the last to go out when ignition is turned on - it's not giving me a problem but it would be nice to know what it is if ever it does!
