If they do use city water, I am sure that they would first make sure it complies with their own specifications. (See section 1.2/1.3 of pdf below). Mercedes are usually very particular about how their dealers maintain standards.

I have seen it first hand. water is pumped straight from the taps into the large drum used for complimentary top off.
Mechanics use an empty gallon can, fill up with water and premix the stuff right there and use an "airlift" setup to fill up the cars.
Its the same all across the board, whether the sign outside was a ford oval or the toyota thread n needle or the nissan hamburger or the mercedes star.
