If you do a search (upper right hand corner), I'm sure you'll find an adequate amt of info. Just the normal though... try and vary the engine speed and vehicle speed. Don't keep it at the same speed for too long. From what I believe and have heard, it is ok to drive it a little hard during the first few thousand miles (gradually doing more), but don't over do it. Try and keep it to a minimum. That's all that I know of.
Congratulations on the purchase! And welcome to Mercedesshop!
