Open the climate view in the centre display by tapping on the temperature button at the bottom centre of the centre display.
Tap on the desired fan level; OFF, 1-5 or Max.
The fan level is changed and the selected level illuminates.
If the fan is fully switched off then the air conditioning is not engaged, which results in a risk of misting on the insides of the windows.
The climate control system automatically adjusts the air flow within the selected fan level based on requirements. This means that the fan speed may change even though the fan level is the same.
