All points of interest in the game are located on the map. If you can't see them, then move the map, maybe the desired point is just out of your field of vision :)
I may have translated it a little wrong since I don't speak the game's language very well, but mission 39 asked me to explore this place, but it's not showing up, or am I doing something wrong?
Actually, it seems that you have something glitched. But I'm not sure yet. Where did you go before this stage? What exactly did you do on the main quest earlier?
Aah, so you're not talking about the main quest? Then just select it from the list of available quests and go to the next point. It is not located where the car is.
