Automatic climate control

The system switches automatically to the 
air recirculation mode if the carbon 
monoxide (CO) or nitrogen oxide (NO

X

) 

concentration of the outside air increases 
beyond a predetermined level, for example 
in a tunnel.

The automatic air recirculation mode does 
not function if AC

 mode is selected or if 

the outside temperature has fallen below 
41°F (5°C). 

The activated charcoal filter should be 
switched off when windows fog up on the 
inside, or if the passenger compartment 
needs to be quickly heated or cooled 
down.

The rear window defroster uses a large 
amount of power. To keep battery drain to 
a minimum, switch off the defroster as 
soon as the rear window is clear. The de-
froster is automatically deactivated after 
approximately 6 to 17 minutes of opera-
tion depending on the outside tempera-
ture.

If you keep button e pressed, the 
side windows and the sliding/pop-up 
roof will be returned to their previous 
positions.

G

Any accumulation of snow and ice should be 
removed from the rear window before driv-
ing. Visibility could otherwise be impaired, 
endangering you and others.

!

If the rear window defroster switches 
off too soon and the indicator lamp 
starts blinking, this means that too 
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system 
responds automatically by deactivating 
the rear window defroster. 

As soon as the battery has sufficient 
voltage, the rear window defroster au-
tomatically turns itself back on.
