There's a tube coming from each corner of the sunroof. Go in the trunk & pull back the carpeting on the sides. The tubes come down just aft of the wheel arches, they plug into some kinda rubber fitting to drain out onto the ground. If the hose comes loose, they drain into the trunk instead.

I've never had to look for the front hoses, but I think they come out near the door hinges or maybe they poke into the wheel well.
