Off the top of my head I would say pry back the spring loaded tensioner, and slip the belt on/off.
Can't remember it being much more than that.

2005 C240 4matic and 2007 ML320 CDI 4matic
I have a 2007 ML320 and the procedure is similar. For the ML320,
1) Look at the ML owner's manual and it shows the belt path. Page 532.
2) Get a 17mm socket and put it on the automatic belt tensioner. Number 3 in sketch on page 532.
3) Use the 17mm socket to turn the automatic belt tensioner counter clockwise until the belt is loose.
4) Remove the belt.
5) Install the new belt according to the correct path until the belt is on the last pulley (you won't be able to get it around the pulley because the tensioner is at full position).
6) Use the 17mm socket to turn the automatic belt tensioner counter clockwise until the belt has enough slack to go around pulley.
7) Gently release the automatic belt tensioner.
8) Wash your hands.
The entire procedure will be approximately 15-20 minutes for your first time. 10 minutes next time.
I replaced my belt at 80k miles and it was worn with small visible cracks. I'll replace it next time around 70k miles.
