Rear window defroster
The rear window defroster uses a large 
amount of power. To keep the battery 
drain to a minimum, switch off the 
defroster as soon as the rear window is 
clear. The defroster is automatically 
deactivated after approximately 
6 to 17 minutes of operation depending on 
the outside temperature.

Warning!
G
Any accumulation of snow and ice should be 
removed from the rear window before 
driving. Visibility could otherwise be 
impaired, endangering you and others.
!
If the rear window defroster switches 
off too soon and the indicator lamp 
starts flashing, this means that too 
many electrical consumers are 
operating simultaneously and there is 
insufficient 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 
automatically turns itself back on.
