Refer to page 60.  
The microfilter removes dust and pollen  
from the incoming air. Your BMW  
center will change this filter during  
routine maintenance. A substantial  
reduction in airflow indicates that the  
filter needs to be replaced early.  
The indicator lamp is always  
active, however the rear window  
defroster will not work if the hardtop is  
not in place.<
