Instruments and controls 71 IB373 The rear-window and door-mirror heating is controlled manually. Switch off the heating as soon as the rear window is clear, to avoid imposing a heavy load on the battery longer than necessary. Note, however, that the heating will go off automatically after 5-10 minutes (depending on the outdoor temperature) or sooner if the voltage in the electrical system falls below 10 V. The ACC system can be programmed to switch on the heating automatically when the outdoor temperature is below 41°F (+5°C) and the temperature inside the car is below 50°F (+10°C) (see "Programming I and II", on pages 73 and 74).

To decrease the fan speed in steps. If the fan is set to 0, the A/C compressor will cut out and ECON will appear on the display. If, after being off, the ignition is switched on but the engine is not started, the fan will run at low speed until the engine is running. Recirculation is selected automatically for effective cooling, but it can also be switched on/off manually.
