Fan Function When Starting





^ It is likely that there will be a build-up of mist on the inside of the windscreen when the car is started after having been parked for up to three hours. Various methods are used to minimize the risk of misting when starting in different conditions.

^ Delayed start of ventilation fan for 15 seconds. During this time, the evaporator in the A/C system has time to cool down and dehumidify the air into the cabin.

^ Delay of ventilation fan start is selected when the outside temperature is 0 - 20 °C (32 - 68°F) and solar intensity is below 400 W/m squared, or outside temperature is 0 - 15 °C (59 °F) and solar intensity is greater than 400 W/m squared.

^ There is always a certain chance of misting when outside temperature is between 0 and 2 ° (32 - 35.6 °F) as the A/C system anti-freeze thermostat disconnects the A/C compressor and the evaporator is not cooled.

^ During the 15 second delay on the ventilation fan, it is not possible to start the fan manually using the buttons on the ACC control module panel. If required, it is possible to cancel this feature using the ISAT scan tool.
