I believe I read somewhere of a suggestion that the answer can be found in the owner's manual. I would try and find out by looking it up in a repair manual at the library, buying a repair manual, or having it reset by the person who services the vehicle (if they have the diagnostic hardware to read and reset the onboard computer). Hope this helps!
