Problems with the rear window heating
The rear window heating has switched off
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 light-
ing.
When the battery is sufficiently charged,
the rear window heating is activated again
automatically.
Activating/deactivating air-recircula-
tion mode

cle will then be recirculated.

Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.
