Rear window defroster
The rear window defroster uses a large 
amount of power. To keep the battery 
drain to a minimum, switch off the defrost-
er 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 tem-
perature.
Activating
Switch ignition on.
Press button
F (
page 135).
The indicator lamp on the button 
comes on.
Deactivating
Press button
F again.
The indicator lamp on the button goes 
out.
Warning!
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 flashing, 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.
