Warning!
Any accumulation of snow and ice should
be removed from the rear window before
driving. Visibility could otherwise be
impaired, endangering you and others.
The rear window defroster uses a large
amount of power. To keep the battery drain
to a minimum, switch off the defroster as
soon as the rear window is clear. The
defroster is automatically switched off after
some time of operation depending on the out-
side temperature.

If the rear window defroster switches off
too soon and the indicator lamp starts
flashing, too many electrical consumers
are operating simultaneously and there is
insufficient voltage in the battery. The sys-
tem responds automatically by switching
the rear window defroster off.
As soon as the battery has sufficient volt-
age, the rear window defroster switches
back on automatically.
