Forgot to say, Reset is not a problem...It resets the dash readings to factory and as far as the Km per 100 they will show as high initially but they will actually reduce if your driving style is smooth or increase if you drag strip race between lights. Sometimes the system seems to get stuck on a number and does not move as mine is now, showing 9.5 due to a really bad air leak. It was at 7.9, so a reset will allow the system to refresh and operate normally, as well as set that value you changed from 1000 to 989 ;)
Gong is three different audible types of warning tone on my car. Not sure what the ? is for, maybe make a selection then move on. I think the port is just the OBD port connect, it is the only port I can think of. Oil temp only shows when the engine is running
