Do I have Hill hold (CVT)?
 

I was just looking at the 2006 model year changes on AudiWorld's main site. It says there is now a "Hill hold function (on all CVT models)."

Does this refer to 2006 or 2006.5 models or what? My car is 2006, even though it obviously was built in 2005.5 or thereabouts.

What is hill hold (I assume it keeps the car from rolling backwards on an incline) and how do I use it? (I'd look in the manual, but I'm not with the car now).

Any ideas?
