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.
X Switch off electrical consumers that you do
not need, such as the rear window
defroster or interior lighting.
X Once the battery is sufficiently charged,
switch on the seat heating again. Seats
