It's my understanding the Generator/Hybrid motor is used to start the engine, while the hybrid system is charged & "Ready". However, I might be wrong, but i believe the 12V battery is there in event the hybrid system is not "Ready" and the engine would need to start via it's conventional starter.
Please correct me if I am wrong, as I don't remember where I read that.
Interesting. I'll have to ask the dealer when I go to pick mine up.
Were you the one that was talking about what happens when you disconnect the battery? How it needed to be reset a certain way to start potentially?
No, more concerned with if battery dies... but I believe there is a jump point in the passenger side fuse panel under the hood, for it that happens... of which I believe you can use any 12v jump pack or jumper cables to another vehicle.
