Problems with the rear window
defroster
The rear window defroster has deactivated
prematurely or cannot be activated. The on-
board voltage is too low because too many
electrical consumers are switched on.
Switch off any consumers that are not
X
required, e.g. seat heating or interior
lighting.
When the battery is sufficiently charged,
the rear window defroster is activated
again automatically.
Activating/deactivating air-
recirculation mode
You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle

vehicle will then be recirculated.
G WARNING
Fogged windows impair visibility,
endangering you and others. If the windows

air recirculation mode immediately should

window fogging persists, make sure the air
conditioning is activated, or press the ¬
