Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Manual program selection
With active manual air distribution, the influence of the sunlight is not compensated. The air distribution can be set individually. Combinations of the individual air distribution buttons are possible (see table below). The selected settings are displayed in the IHKA display.
- Air distribution, top Pressing the top air distribution button guides the air-mass flow to the air vents for defrosting.
- Air distribution, center Pressing the center air distribution button guides the air-mass flow to the ventilation air vents.
- Air distribution, bottom Pressing the bottom air distribution button guides the air-mass flow to the footwell air outlets
- Defrost function Pressing the button for defrost guides the air-mass flow to the air vents for defrosting. The blower output is set by the IHKA control unit to the maximum level. For the defrost function, the maximum blower output is always available, as this function is relevant to safety. The heated windscreen (if fitted) is switched on. The blower output can be lowered manually.
