Hi,
Jumper Cables in SC? I thought that was only part of the
Yankee Roadside Troubleshooting kit...
Seriously, they are most likely to be just extra weight. Check your Owners Manual, there is a very definite (and somewhat non-standard) procedure for jumping one of these cars. Failure to observe this could fry something expensive.
If my car were later, with the electrically operated hatches, I'd probably rig a 9-volt battery terminal to a Cigarette Lighter Plug (available through Radio Shack and such - observe proper polarity) and keep it, and a fresh 9-volt battery in the car. This would give sufficient power (Ignition OFF, key OUT) to pop open the lids to get a jump. Most likely the battery would be exhausted with a single use due to it's small capacity, but, it would work.
Other then that, if your car is a manual, you can always go with the Tried & True method of pushing it and popping the clutch in gear. Hope this helps...
Happy Motoring!... Jim'99
