As Longmtnman said, get the factory manual from your dealer. You might be able to save a bit of cash if you can find one on Ebay, but that can be risky.
There is an aftermarket manual from Haynes just out or soon to be out that might be a good idea to get as a suppliment. The publisher has a long reputation for being very good with pictures but a bit short on accuracy, so I wouldn't recomend relying on it as your primary source of information.
