This place is a joke.
1) Activates your charcoal A/C filters. Expect reduced air volume but will scrub the air of any odors. Especially useful for exhaust fumes from a car or truck in front of you. Hit that button and the recirc. button to clean your interior air.

2) Door locks. Not sure how you don't know this.

No no. The button below the defrost button is to prepare the car prior to hitting a brick wall.

Okay, how about these buttons on my old 911?



Special control buttons, Rocket thrust and ejector seat.

Is this the same as the cabin air filter? If so, can it be replaced?
