This morning I have a yellow light on the dash board next to the speaker. It was on solid , not blinking. What does fit mean?
I'm. thinking that I may have left the car in the accessory mode overnight, and the yellow light warns of that.
The Yellow light on dash is lit when the 12 Volt battery is being charged from the HV battery. Perfectly normal and a good sign that the I5 is looking after itself. There is a constant drain on the 12 Volt battery to keep everything running/monitored. The drain may be small but it is a drain nevertheless so an occasional charge is needed. Of course leaving the car in accessory mode would be a bigger drain and I'm not actually sure if the maintenance charge would take place or if accessory mode would eventually turn off. I usually just go to ON mode, even if just playing around to assure 12 Volt is maintaining a charge.
