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.
Activating
Press buttonF (
page 198) or
(
page 210) or1(
page 199)
or (
page 211) on the respective
climate control panel.
The indicator lamp on the button
comes on.Deactivating
Press buttonF or1 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
automatically turns itself back on.
