MB does not provide manuals for the consumer. The have used microfiche which is very expensive and only a professional mechanic could justify the expense. A mechanic agreed to let me copy the microfiche for my car. Don't waste your time trying to do like I did.
The best source is Alldata. This is an online manual that some mechanics use. One year is around $14. Or, you can buy the CD for your car on eBay. I have done this a couple on times and have never gotten a CD that was completely helpful.
Good luck
