"Discovered" a weird feature on my 2001 3.0i. I don't know if it is temperature dependent (I'm up in South Lake Tahoe, where it is close to freezing temps), but never noticed it before ...

When taking the key out, with the wipers set to intermittent, (and maybe it has to be pretty cold as well), it moves the wipers up to 12 o'clock as the car shuts off.

This makes sense if you're worried about snow accumulation freezing the wipers into place down low. Also, you could pull them away from the windshield when up high, to prevent them from freezing to the windshield.

I tested it a few times, and was impressed. It automates something I used to have to do with my other cars when parking during snow - setting the wipers wiping, then pulling the key out at the right time to kill them when they're up high.
