Problems with the seat heating
ProblemPossible causes/consequences andMSolutions
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.
XSwitch 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 will switch
back on automatically.
