You can deactivate the flow of fresh air if unpleasant odors are entering the vehicle from outside. The air already inside the vehicle will then be recirculated.

WARNING
Fogged windows impair visibility, endangering you and others. If the windows begin to fog on the inside, switching off the air recirculation mode immediately should clear interior window fogging. If interior window fogging persists, make sure the air conditioning is activated, or press the button.

Turn the SmartKey to position 2 in the ignition lock.

To activate: press the rocker switch up or down.

The indicator lamp in the rocker switch lights up.

Air-recirculation mode is activated automatically at high outside temperatures. The indicator lamp in the rocker switch is not lit when automatic air-recirculation mode is activated.
Outside air is added after about 30 minutes.

To deactivate: press the rocker switch up or down.

The indicator lamp in the rocker switch goes out.

Air-recirculation mode deactivates automatically:
• after approximately five minutes if outside temperatures are less than about 41 °F (5 °C)
• after approximately five minutes if cooling with air dehumidification is deactivated
• after approximately 30 minutes if outside temperatures are over about 41 °F (5 °C)
