Solutions
The seat heating 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 heating can be
switched back on manually.
