Instruments and controls 103 Manual climate-control system Fresh air for the cabin is drawn in through an inlet grille at the bottom edge of the windshield. It passes through a filter before reaching the climate control system and delivery into the cabin. The air is evacuated via openings in the parcel shelf. It is then led through outlets on either side of the car behind the rear bumper. The incoming air is treated in three stages: first it passes through a filter; it is then dehumidified and cooled; and finally, if required, it is heated. To optimize the performance of the A/C system, all windows and the sunroof should be shut. To reduce potential misting on the insides of the windows, the glass should be cleaned with a quality glass cleaner. How often this will need to be done depends on how clean the air is - if there are smokers in the car, the windows will need to be cleaned more frequently.
