I have a 2009 Prius and I think the battery died. The manual says to disconnect the ground wire before attempting to charge. I assume the ground is the black wire leading from the negative terminal and connected to the inside of the trunk hood with a screw, but wanted to make sure. Anything I should know that is different about a Prius than a standard vehicle before attempting to jump it?

I have a 2009 Prius that hasn't been run in a month and a half or two months. I went to start it and it doesn't do anything. I was going to jump start it to check to see if that is the problem. The owner's manual says to disconnect the ground wire first. I'm not sure which is the ground. I assume the black wire leading from the negative terminal to the the inside wall of the trunk but wanted to make sure. Is there anything else I should know that is different from an ordinary car before attempting to jump start it?
