Instruments and controls 67 Automatic climate control (ACC) The ACC system automatically works to maintain the desired temperature inside the car. The system will achieve the desired temperature in the quickest possible way. Note that selecting a higher or lower temperature than that desired will not speed up the process. For the ACC system to be most effective, all windows (and sunroof, if fitted) should be closed. Fresh air for the cabin is drawn in through an inlet grille adjacent to the bottom edge of the windshield. The air flows through a filter upstream of the ACC system before delivery to the cabin. Cabin air is evacuated via openings in the rear parcel shelf and then through outlets on either side of the car behind the rear bumper. ºF AUTO ºC ECON OFF ºF ºC 2 1 3 4 AUTO 5 6 ECON OFF IB367 9 7 ACC panel 1 2 3 4 5 Temperature setting: LH side AUTO: All settings selected automatically Manual setting of fan speed Manual setting of air distribution Rear-window heating: ON/OFF 6 7 8 9 8 Recirculation: ON/OFF A/C compressor: ON/OFF ACC system: ON/OFF Temperature setting: RH side The incoming air is treated in three stages: first it passes through a filter; it is then dehumidified and cooled and, finally, if required, heated. The ACC system also includes a charcoal filter which further improves the quality of the cabin air. This filter is a special benefit to allergy sufferers, as it reduces concentrations of noxious substances, such as benzene and toluene. To reduce the likelihood of misting on the insides of the windows, the glass should be cleaned with a quality window cleaner. How often this will need to be done depends on how clean the air is - if there are smokers in the car, cleaning will need to be done more frequently.
