I haven't had to do this yet, but I did ask the dealer when I bought it how to DIY the refill. My notes at this point are skimpy, but what I noted was that I should push in the little panel bear the left rear wheel and fill the top reservoir. There is a top and bottom reservoir opening. What I am wishing to confirm is whether you fill both reservoirs in some sequence, or just the top, or just the bottom?
