78 Instruments and controls Air conditioning (A/C) The air conditioning is combined with the conventional climate-control system and is switched on by pressing the button, provided that the fan control is in position 1-4. 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 air conditioning can be used at outdoor temperatures down to 32°F (0°C). Recirculation When the button is depressed the regular air intake will be closed. In this position, the air inside the cabin is recirculated. Use recirculation when you want rapid cooling, at extremely high air temperatures. Switch the air conditioning (A/C) on first. Recirculation can be useful to activate manually to prevent unpleasant smells being drawn into the car from outside. Note that recirculation should not be used when the outside temperature is lower than 50°F (+10°C) except briefly, e.g. to avoid unpleasant air from entering the car. Prolonged use of recirculation could cause the windows to mist or ice up. Air vent at rear side window IB794 Condensation water When the A/C compressor is on, the incoming air is dehumidified. The resulting condensation water is drained away through an outlet under the car. It is therefore perfectly normal for water to be seen dripping from this outlet when the car is parked. The warmer the ambient air and the higher the humidity, the more condensation will form.
