Problems with the steering wheel heating
If steering wheel heating indicator lamp 3 is flashing, the steering wheel 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 steering wheel heating will switch back on automatically.
