Problems with the rear window defroster
Problem Possible causes/consequences and M M Solutions
The rear window
defroster has deacti-
vated prematurely or
cannot be activated.
The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again.

tion mode
General notes
You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
