Rear window defroster
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.

Warning!

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.
