Have some patience. It's doing just fine, but it needs more time.
I pulled up the instructions for this beer. I assume that you don't have a way to hold lager fementation temperatures and that you probably did your primary fermentation at 65F+. It isn't surprising that it fermented so quickly at higher temperatures.
Leave it alone. It's doing fine. Let it sit for a while and clear. Just because the airlock is no longer bubbling, doesn't mean that the yeast is done. They are busy cleaning up fusel alcohols and diacetyls.
Basing fermentation activities on time is not the best way to go. Every fermentation is different.
You've probably fermented at a temperature higher than 70F.
I suggest that you let it sit for at least two weeks total, before bottling. It wouldn't be a bad idea to try and drop the temperature down, as the instructions suggest before bottling it.
While your waiting, either get the book "How to Brew" by John Palmer or read the older online version.

The book will be an eye opener.
