RE: QUESTION ABOUT ESC BUTTON
There are two times that most people would consider turning ESC off.
1. You are stuck in snow - Having ESC on while the wheels are spinningand trying toescape is kind of counter productive.
2. You are stuck in mud - Same thing, ESC senses the vehicle is not "under control" as you try to escape and will make adjustments that will basically keep you stuck.
Perhaps Sand or otherwise loose material you are stuck in would also fall into these categories.
Otherwise probably best to keep it on.
