Loud knocking cold startup

My compass has a very loud knocking noise when started cold. It lasts for about 5 minutes, then goes away. It is definitely engine related, because it speeds up if I press the gas. I'm afraid I am doing damage....Any ideas???

Have you talked to the dealer? They may want to keep it over night so that they can do a cold start.
