Air from outside the vehicle enters below the windscreen through a pollen filter and leaves again by forced air extraction above the tailgate or the rear doors.
Pollen filter
The pollen filter is located under the wind cowl grille on the right-hand side on LHD vehicles, and on the left-hand side on RHD vehicles (as seen looking from the driver's seat).
Protective screens to trap large particles are installed on the left- and right-hand sides of the pollen filter.
