You can go here:
Toyota | Lexus Service Support
and subscribe for a day or longer to have access to all the PDF files for the Toyota shop manuals. I spent $50 for a one month subscription and copied all the files I needed for my '06 Avalon, my wife's '03 Highlander and my parents '04 Camry. Not a bad deal considering the paper shop manuals will cost you $250-$350.
