Can anyone tell me what this switch is?

Hi all,

Just got a 2010 Yaris here in Sydney. I noticed this unlabelled switch on the dash. Any one able to tell me what its for before I start trying to follow the wire?

Nothing seems to happen when flicking it. Car starts with it in either state.

Many thanks

That's aftermarket, you'll need to trace it down.
