Newer Nissan Leaf (Leaves?) do not have that option. I guess this buffer is now built in? Mine has just passed the 12k mile, I don't notice any degradation. Indicated range is usually 100+ miles, which is meaningless. Once highway driving starts, it's more like 80 miles and is pretty accurate if doing 65MPH. Higher speeds will decrease that range. Fun anecdote: I went to a park late at night to watch the perseids meteor shower. A arrived near the park with 20 miles remaining. Which was fine, as there was a quick charger nearby. Me and my wife decided not to waste time and just hit it on the way back. Due to unfamiliarity with the area, I was misled by the GPS and went to the other side of the park. So I had to circle back and go uphill to reach the rendezvous point, a parking lot inside said park. Estimated range showed "---", 7% state of charge. We had about 8 miles to go to reach the charger. We added 2 more miles by taking a wrong turn in an area with no phone and GPS reception. So 10, which took two times the amount of energy I figured I had. Since it was almost 3 am, I just drove at the slowest possible speed I could, 15 MPH. Arrived at the charger with 4% remaining(dash showed "--%", still one bar lit). I doubt I would have made it at normal speeds. Now, this is only possible because EV battery charge is extremely accurate, compared to fuel gauges in ICE cars.
