to a minimum, switch off the defroster as

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
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 automatically.
