This light indicates that you main computer has detected a problem with the OBD11 emmision system . It doesnt mean not to drive it but it will need to be scaned to tell which part of the OBD11 system is causing it. No big deal at all I might add that in the case of a major malfuntion of the OBD11 system (like a broken cam sensor whicj=h is required for the engine to run) the engine will still operate on the computers default settings untill the problem is fixed, A sorta back up fail safe system which is pretty neat.
