Hummmm, let's make it a McGuyver challenge:

- 12 VDC battery is drained flat
- 273 VDC main battery pack is drained flat
- Swiss Army knife, metric tool box edition with VOM
- my Prius with 1 kW UPS

I would remove the main traction battery cover and rewire the batteries in parallel. Next, I would jack-up one front tire and wire the MG2 leads into a rectifier array using diodes from the disassembled inverter. I would turn the tire to generate the power needed to recharge the batteries to at least 45% SOC and reassemble the battery pack. Next, I would hook-up and recharge the 12 VDC auxillary battery to at least 12.5 VDC. Finally, I would let the car down and start it up.

ps. Alternatively, call AAA to tow the car to the Toyota service department and tell them, "It broke, fix it."
