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