The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should alway sobserve the
interval for replacing the filter, which is
specified in the Servic eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Servic eBooklet. G
Risk of accident
Observe the settings recommended on the
