Recirculating air push-button, function - GF83.40-P-2102-01GI

Function 

A brief actuation (< 1.5 s) of the recirculating air push-button ( ) energizes the actuator motor for the fresh air/recirculated air flap, which activates the fresh air/recirculated air flap and thus closes the fresh air duct and opens the recirculation duct, in order to enable the air supply from the passenger compartment. The function LED illuminates during recirculation mode.

Recirculated air convenience closing function 

If the recirculating air push-button ( ) is pressed for longer than > 2 s, then alongside the recirculation function, all open windows and the sliding and tilting roof are automatically closed (window and sliding/ tilting roof must have been normalized  ). The function LED illuminates during recirculation mode. In order to prevent any current peaks the sliding/tilting sunroof and power windows are actuated successively.

If the push-button is pressed again for > 2 s, the windows and the sliding/tilting sunroof return to the previously stored position and the fresh air/recirculated air flap moves to the fresh air position (LED off).

The convenience closing function can only be started if the recirculating LED is not illuminated.

Each window, which has been manually opened during the recirculation phase, remains in this position if the recirculating function is cleared: all other windows move to the stored positions. The position of the sliding/tilting sunroof prior to the start of the closing operation and that of the side windows is stored in the memory. The windows and the sliding/tilting sunroof which have been closed by the convenience closing function, remain closed if the recirculation push-button was only pressed briefly (t < 1.5 s). In this case, only the fresh air/recirculated air flap is moved to the fresh-air position. The stored positions are cleared when the ignition is switched off.
