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 
operation depending on the outside tem-
perature.

With the sunshade raised and the respective 
door window open, the sunshade could disen-
gage and snap back when driving at high vehicle 
speeds, e.g. on highways, and damage the 
retractor. You should therefore always either 
close the door window or lower the sunshade 
when driving at high speed.
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, too 
many electrical consumers are operating simul-
taneously and there is insufficient voltage in the 
battery. The system responds automatically by 
switching the rear window defroster off.
As soon as the battery has sufficient voltage, the 
rear window defroster switches back on auto-
matically.
