Hey everyone, new Audi owner from a history of Volvos. Looking through the manual, it talks about the allroad having an auxiliary heater. What is that? After trying several Google searches, it's anything from a windshield warmer, to a pseudo cabin heater (kinda like a remote starter for us in the US). My options in the MMI system are 'auto' and 'off'. Wonder if anyone actually knows what it is and does, and if it IS indeed a cabin pre-heater, how I activate it.(?) Thanks in advance. (2013 allroad)
