ation depending on the outside
temperature.

Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,

!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.
