Don't know if everyone is aware of this, but I just found that there is an extensive on-line interactive owners manual for the GLK.

In particular, the in-depth section has lot's of good info. Great for those of still awaiting our cars, but also useful to look stuff up when paper manual is out in car.

Maybe this should be in stickies?
