Problems with the seat heating
The seat heating has switched off prema-
turely or cannot be switched on. The vehicle's
electrical system voltage is too low because
too many electrical consumers are switched
on.
XSwitch off electrical consumers that you do
not need, such as the rear window
defroster or interior lighting.
XOnce the battery is sufficiently charged,
switch on the seat heating again.
