The IMA light and several other dash warning lights came on while my daughter was driving it. After she shut it off at home, I started it up at home later that evening. The backup starter actually started the engine (I had never heard or felt it before) and the IMA and other dash warning lights came on. I drove it around the block, wasn't running correctly, parked it and disconnected the 12 volt battery for about an hour. I hooked up my 10amp battery charger and left it on for several hours reconnected the 12 volt battery. I later started the engine. It started off the IMA system and the car ran normally except the hybrid battery was at 1 bar. I drove it around the block a few times and got the hybrid battery bars up to 2-3. I shut it off and hooked up the 10amp charger for several more hours. When she started it the next day, the bars were up to about 5. She drove it to work and came home, now the hybrid battery is fully charged.
What is goin on? Does charging the 12volt battery also charge the hybrid battery?

 

I'm afraid not. H

 

short answer is "no"
