Thanks! The dealer provided me a Chinese Owner's Manual, which would be very time consuming for me to go through. I am a 1st time BMW owner so even the most basic visual indicators i may not fully understand the function. It also doesn't help that the dealer told me the wrong info.
When i picked up my E90 last weekend the staff who goes through the car functions with new owners told me that the re-circulating air button means to pull air from the outside. I asked 3 times to make sure what I heard was correct since the air quality here isnt the best when you are trailing a bus or big rig. I asked if i want to circulate the air inside the car what is the button or indicator. His reply was that when all lights are off that is when the air is being recirculated. The re-circulating indicator light he mentioned means to pull air from the outside.
