Problems with the seat heating
If one or all of the indicator lamps in the seat heating button are flashing, the seat heating has switched off automatically. The vehicle's electrical system voltage is too low because too many electrical consumers are switched on.
► Switch off electrical consumers which 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.
