The gen III Prius has jumping ports under the hood to make "jumping" the Prius just as easy as any other vehicle. You wouldn't want to provide a jump to other vehicles with those ports, however. On the Prius, the 12v battery mostly just powers on the computer and runs some low voltage pumps to get going, and doesn't need high cranking amps. For that reason, providing a jump to someone else would be a bad idea, unless their car was also a Prius.

Now that I think about it, I rather like locating the 12v battery in the interior of the vehicle because it provides better temperature stability. I'll have an easy time of replacing my lead-acid battery with a LiFePO4 when it comes time.
