please help, I don't own this car but i am writing on behalf of my uncle, im in Europe, and unfortunately we don't speak German. The question is how do you refill the headlight washer reservoir?
One more question how or where do you change the stock cell phone adapter?

 

Washer resovoir is under the hood. Open the top and pour in the fluid.

No idea on the cellular question.

 

the washer fluid all goes in the same spot
