Problems with the seat ventilation
Problem Possible causes/consequences and M Solutions
The seat ventilation has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off electrical consumers that you do not need, such as
the rear window heating or interior lighting.
Once the battery is sufficiently charged, the seat ventilation will
switch back on automatically.
