Problems with the seat ventilation
If one or all of the indicator lamps in the seat ventilation button are flashing, the seat ventilation 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 ventilation will switch back on automatically.
