I've recently bought a 2010 Allroad C6 3.0 TDi.

Lovely car and a nice progression from the A4 Quattro with the same engine. I'm after any tip for useful features that are not immediately obvious. For example, it was only by accident that I realised that by tapping the accelerator pedal when in traffic with the electronic handbrake on, it released the brake without having to do it, well, manually! A simple but very nice little feature

I know, I could read the manual cover to cover, but I have neither the time nor inclination to be honest, so I wanted to ask if anyone has their own personal favourites that might not be immediately obvious or common knowledge?
