    I recently bought an 12v battery jumper pack. I wanted to make sure I could easily access the 12v battery before actually needing to. The space between the two terminals are so cramped that I can't get both cables to fully clamp around the terminal connectors. Would it be okay to connect it to the bolts/nuts as shown in the image instead of fully around the terminal connectors? Has anyone had to do this before and been able to jump start their prius C?

    Why not just use the jump point under the hood; rather than rip out the access panel under the seat???o_O:sleep:

    The cables are very short. I couldn't reach the spot that was recommended to connect the negative cable clamp to.
