The auxiliary ventilation makes it possible to supply
fresh air to the vehicle interior when the engine is
switched off. As a result, the interior temperature is
lowered, e.g. when the vehicle is parked in the sun.
The Air Care function reduces the penetration
of pollutants into the vehicle interior. At the
same time, the air is both circulated and
cleaned.
What you should be mindful of
The air purification process is displayed in the
Infotainment.
For proper operation, the doors and windows
must be closed.
