OK, been away for a while, but what's with all this mountain mode talk? Why, unless you know you have a weak cell (or are planning to scale a mountain), would you use mountain mode?
Just yesterday, I drove on electrons for 10 miles until I got on the interstate. Then, I switched to Hold mode until I got off the interstate. Stayed in Normal at my destination and on the way home until I ran out of juice back on the interstate about 20 miles down the road, finishing the trip in CS mode. I got the maximum electric miles (well, I used up all the e-miles the car had), and charged up when I got home. What would have been the advantage to using mountain mode?
