I'm in Europe, in case you're on the "wrong" side of the pump you just have to make sure that you park the car a little further, so you'd get the pump hose through the back and on to the other side without scratching the car's paint. That's all it is to it. I'm from Romania and I've driven (and hence re-fueled) my car all the way from Bretagne, France, to Peloponnese, Greece, never had a problem.

I also don't know anything about any "arrow" signalling anything in my dashboard, maybe it's only on the US-made cars, I wouldn't know cause I generally know on which side I have to fuel my car.
