  Note!
t  With the air recirculation option there may be fogging of the windows (due to an increase in the humidity of the air in the passenger compartment and its deposit on the windows; the air is not dried as it is in vehicles fitted with air conditioning).
t  The function “air recirculation option” is erased when the ignition is switched off. When the ignition is turned on again, the Servomotor for the fresh air / air recirculation flap -V154- is activated by the Heating Control Unit -J65- and the heating changes from the air recirculation option to the fresh air option (if the air recirculation option was previously selected).

t  To clear fogged windows as fast as possible, it is only possible to use the air recirculation option for a limited time, with the rotating control for air distribution -B- in position “air to windscreen”-D-. The Heating Control unit -J65- changes for example to the fresh air option after turning the rotating control to this position (and the LED warning light on the button goes out).
t  Test the operation of the button for the air recirculation option and activation of the Servomotor for fresh air / air recirculation flap -V154- → Chapter.
