Online here : C-Class Coupé - Interactive Owner's Manual - [Start] Lots of info on where all the various systems and toys are installed and how they work, including video tutorials and in-depth instructions. Coming back into MB after a few years with other marques, I am amazed by some of the technology. For example, I thought that the speed limit assist just used the Becker database, but it actually *reads* the road signs..! There's lots more here and I guess most of it is applicable across the whole range, i.e. there is a large section dedicated to COMAND Online.
