AUC when active (LED on) will close the car for outside air when it detects smog or pollution, to open again when it thinks the air is clean enough OR the passenger compartement has had the same air for too long.
The button ahs 3 functions :
LED's out :
normal function, fresh air
Left LED on:
automatic system when high polution is measured fresh air valve
close and only the air in the car circulates, when polution is
low valves open again.
Right LED on:
Fresh air valves are closed and only air in the car circulates.
It is not recommended to use this option for longer times
because it does'n't use fresh air anymore.
