If you are pulled over, they will either pull you over on the spot, or escort you to a safe place (e.g. parking lot if you are pulled over on a highway).
Shut down your engine, roll down your window, keep your hands visible. The officer will approach you, and will provide you with further instructions.
This goes for any country. If they want you to do something, they will ask/order you to. In general, police in Europe isn't as trigger happy as the US police. Only if you are trying to escape, cause some major traffic accidents, and try to run over cops, they might shoot at you. If you do something they don't like, they'll ask you to ("please remain in your car", "please shut down your engine", ...). Just follow up their orders and you'll be fine.
