However, there is a section in the manual about jump starting. Preparation is:
1) Check battery of vehicle offering the jump to make sure it is 12 V.
2) Switch engine off of vehicle offering the jump.
3) Switch off electronic consumers in the offering vehicle.
I guess as long as it is not over 14 Volts then all is fine.

So none of the "leave the engine on for the car that is giving the jump" business. I'm thinking that is solely due to voltage. It's been awhile but I believe the alternators usually put out around 14V while the batteries are around 12V. Makes sense if these new batteries don't like more than 12V.
