I found a method to completely disable it in the manual. Its not a simple button, its long series of non-intuitive steps. I will see if it works. I should have to read the manual first.
I was really hoping to find a way of making it less sensitive. Particularly on shallow hills where it is really annoying. It kicks in on almost any incline, places where it doesn't do any good. I will talk to the dealership about it on the first service. It would be a good idea if it was actually practical.
Thanks for the help
