That's for 2007 vehicles, the USA 451 is a bit different. I've gotten guidelines for 2006 and 2007, read and digested, and made some comparisons. I've emailed Daimler asking when a updated manual will be unavailable, but have only gotten a 'bot acknowledging receipt of my question.
I doubt that 2008 protocols will differ significantly from 2007, but I just want to be sure. I'll report back when I get the response.
