Ventilation
Setting
The air flow directions can be individually ad‐
justed:
▷Direct ventilation:
The air flow is directly pointed onto the per‐
son. The air flow heats or cools noticeably,
depending on the adjusted temperature.
▷Indirect ventilation:
If the vents are fully or partly closed, the air
is directly routed into the car's interior.
Front ventilation▷Turn knob for continuous opening and clos‐
ing of the vents.

Parked-car ventilation
The concept
The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing two preset reel-on times. It remains
switched on for 30 minutes.
Open the vents to allow air to flow out.
