I have a 2000 V70 XC AWD and no manual but I found a free download and printed it myself. It's big but complete. Go to devicemanuals.com and try there. I got mine from a Volvo website but can't find it now. It was a Volvo books thing but you'd have to look around for it. Also try entering "free download volvo owner's manuals." You can get a free one but have to try different things.
I suggest going to Ebay.com. That's where I bought my manual. There are a number of offers there that not only include the printed manual, like the one a new car owner gets, but also a PDF version, for making a check on the computer.
I just a 99 volvo v70xc awd manual from my volvo dealership down the street from me for $50.00 so check with your closest dealership.. if they do not have one then ask them to search for one for you..mine was brand new
