The rear window defroster uses a

turn off the defroster as soon as
the window is clear.
The defroster is automatically
turned off after a maximum of
12 minutes of operation.
If several power consumers are
turned on simultaneously, or the
battery is only partially charged, it
is possible that the defroster will
automatically turn itself off. When
this happens, the indicator lamp
inside the switch starts blinking.
As soon as the battery has suffi­
cient voltage, the defroster auto­
matically turns itself back on.
