when you turn on your head lights pull on the end of the handle and that will turn your fog lights on, esp is eletronic stability program basicaly it keep the nitro from slipping around in the snow,mud and stuff like that, I have another post around here about the esp. I turn it off in the snow to have some fun. As far as gas I burn 86. Dont use anything higher the motoer is not designed to burn anything else.
