What does the service engine soon Warning Light mean?

The service engine soon Warning Light is located on the instrument panel. This light illuminates solidly when the on-board diagnostics system (OBD-II) has noticed a malfunction. If the light is blinking, then the OBD-II has detected that the engine is misfiring. If this is the case, drive very carefully, and schedule maintenance as soon as is possible. Tip The service engine soon Warning Light briefly illuminates when your car is first turned on. The light is only a problem if it stays lit for an extended period.
