Looking at the steering wheel, it looks like there is a button I have to press and hold for wiper fluid to come out. When I hold it down, the wipers go back and forth, but I don't think any liquid is coming out. Note that I tested this in the rain, so if it is doing something fancy like having the fluid drip from the top then I didn't notice. My assumption is that fluid would spray from the bottom like all other cars, and that did not happen. There is no warning on my dash that it is out of fluid. Am I doing it wrong? Or is there something wrong with the car?
