I don't notice them working. Are they suppose to adjust delay according to vehicle speed?

 

No not the Delay, But when you have it On delay, think as your Speed Increases, the speed of the Swipe Gets faster according to your Speed. So the faster you go, the Faster they Wipe the Window, and slower as you Slow Down. Hope you understand that, LOL.

 

That's what I figured after reading the manual. But I don't really seem to notice the difference from stop vs 100+kph. I actually notice the difference when I'm in my friends bimmer.

And of course I have it set on in the settings!
