If you're just starting out, you shouldn't be doing a lager. If it says lager, chances are it doesn't come with ale yeast. You need to either get a different yeast (which will change the final beer) or find a way to keep your beer at 50F for a few weeks. After fermenting at 50, you will have to lager it at 30-35F for another few months in order to do things properly.
I suggest picking up a kolsch yeast. It should be fine at 62F.
