The ventilation of the rear heavy duty automatic air conditioning system (roof air conditioning) can only be controlled or regulated over the rear blower control button (+) and the rear blower control button (-) integrated in the AAC [KLA] control and operating unit if it is switched on by the integrated rear air conditioning button.
Activation of the rear heavy duty automatic air conditioning system (roof air conditioning) is indicated by the red light emitting diode (LED) lighting up in the rear air conditioning button. The ventilation circulates the recirculated air (air circulation) and also ensures that a homogeneous and comfortable temperature is provided in the vehicle's passenger or load compartment.

Ventilation is only provided in air recirculation mode, no fresh air is drawn in.

The blower motor (A32/3m1) draws in the recirculated air from the vehicle's passenger compartment or the load compartment over the dust filter located behind the dust filter grating.

The rear blower control button (+) and the rear blower control button (-) can be used to regulate the rate of circulation of the air recirculated by the blower motor.
The AAC [KLA] control and operating unit regulates the blower regulator (A32/3a1). The blower regulator controls the voltage applied to the blower motor. The rear blower control button (+) and the rear blower control button (-) can be used to adjust the blower motor output via the blower regulator to the four following stages:
- Stage 1
- Stage 2
- Stage 3

The blower motor cannot be switched off using the rear blower control button (+) and the rear blower control button (-). The blower motor can only be switched off by switching off the rear heater using the rear air conditioning button.

Distribution of the recirculated air is conducted using the roof air duct and the swiveling, lockable air vents.

The recirculated air exit in the roof area is also dependent on the position of the vent flaps that are integrated into the swiveling, lockable air vents.
