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 af-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside 
temperature.

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.
!
The rear window defroster cannot be 
switched on when the retractable hardtop is 
open. The indicator lamp will start flashing if the 
hardtop is open.
Close the retractable hardtop.
The rear window defroster can then be switched 
on.
!
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 automatically switches 
back on automatically.
