In the front of the vehicle, the 4-zone IHKA has the same control panel as the 2-zone IHKA.

The 4-zone IHKA has an additional control panel in the rear passenger compartment. The rear seat passengers can use this to adjust the temperature separately for the left and right. The amount of air and air distribution can be controlled together for the rear passenger compartment.

With the 4-zone IHKA, the driver's current settings for temperature, amount of air and air distribution can be transferred to the front passenger side and rear passenger compartment using the ALL button.
