Whats this button do?
This is not my picture but it is the best I can find.

The On toggle switch at the top of the button cluster. No indications/lights on the dash/dial cluster so I have no idea what it does!
The manual makes reference to a VSA switch but that is an Off only button on the dash and is on a per startup basis, it also has a VSA indicator light so it cant be that?
Someone please enlighten my noobness before I turn it off and might learn the hard way
