Today I drove my Model S until it was showing two miles of range remaining. I wanted to see what messages or warnings I would get as I got close to empty. Like the Roadster the battery icon goes from green to yellow to red as the battery is depleted, but the yellow and red show up later (when the battery is more depleted) in the Model S. If I remember right yellow is somewhere in the 20s and it didn't turn red until I was down to four miles of range.
Other than that there are no warnings, no pop-ups, no chimes - nothing. I'm just guessing here but there's probably some reserve when you hit zero, just like in the Roadster (in standard mode, at least). I charged in range mode before leaving and at the end of the trip it showed that I had used 77.4 kwh, so again, looks like there's a reserve somewhere. What I'm wondering is: Do you have to do anything to access this reserve? Is it like driving a gas car with the fuel gauge way below empty, or do you have to call Tesla Roadside Assistance for help? Another guess, but it's probably the former. The warning messages probably start popping up when you get to zero range indicated. I'm not quite confident enough to test this theory. Anyone know if I'm right?
This is unrelated, but if anyone was wondering the car was showing 273 miles of range when fully charged in range mode, and I drove 240 miles with two miles of range indicated at the end. Mostly two lane highways and city driving, not much interstate, so the actual to ideal ratio was pretty close to what I'm used to getting in the Roadster.
