Ok, so here goes....since there's pretty much no equivalent to your car here, i went online to find some pics of it under the hood(bonnet). So, if you open said bonnet, look towards the base of the windsheild and towards the either left or right edge. There should be a small door or cover that if you open it there should be hiding the fill cap underneath. And usually(over here anyways) the fluid is blue, if only because of the methanol thats put in it to keep it from freezing.
