Default I did that once, and I did run out of assist...

Well, not an expert like maybe some other drivers who routinely drive in mountainous areas, but I *have* one time driven up from 1500 to 12000 feet in Arizona.

I ran my battery dry more than once. That means 3rd gear, 4000 RPMS to maintain decent speeds when climbing a decently steep grade. I had a fresh oil change to Synthetic Oil just the weekend prior, so the high RPMs did not hurt me, but it was kind of different.

I still got 48.8 for a 230 mile mountain day trip, so I was not too upset !!
