Another thing you might notice on your Tig is that every once in a while when you switch your car off or turn it on, the wipers will "twitch", basically just move a couple of millimeters up or down. It's to prevent them from sticking to the glass and baking on, in areas where you might not use your wipers for weeks of months at a time. It supposedly keeps the blade's edge in healthier shape.
Pros: keeps blade's edge healthy
Vehicle:
Volkswagen Tiguan
