You can easily get away with just topping off with distilled water if it is in the order of a cup or two (probably more). I'm a stickler, so anything above that I'd go with a 50:50 mix. But where you are doesn't get THAT cold, so you are probably ok no matter what.

My V70R seemed to mysteriously need a light top off every few years. My LR4 has required it as well, but soon enough I will be doing a lot of preventive cooling system work on that car.
