How do I toggle the windscreen wipers on and off?

So I was steadily racing along in my Lotus Elise, approaching a corner, when I was slightly distracted.

Needless to say, this distraction ended with me going sideways across the gravel, and in a blind panic to halt my car before I was three miles off the track, I ended up button mashing to find the handbrake.

While this was occurring, I must have pressed something else by accident, since the windscreen wipers turned on. When back on track I continued to button mash but could not find the button I pressed to turn them off again, nor could I turn them on in a future race.

What button toggles the operation of the windscreen wipers?

Solution 1:

To toggle the wipers, press R3 (push the right analog stick in).
