The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on.
The on-board voltage is too low because too many electrical consum-
ers are switched on.

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 heating or seat
ventilation can be switched back on manually.
