Just tested this the other day buy running the tank down. After the single bar is on for a while, the yellow fuel light comes on and the single bar begins to flash. At that time if you scroll the middle display line where fuel consumption, avg speed etc are, you will see both the amount of fuel left, and the estimated distance to empty. In my case (metric) it showed 3.2 litres remaining (which is bang on 0.8 US gal) and 74 KM (which is about 43 miles).A
As a extra note, when I filled, it still showed 2.1 litres remaining. I topped up fully, on the side stand, and took 15.240 litres which when added to 2.1 gives17.3, well short of the specified 18.8 litres, so I am thinking that the estimated remaining fuel (2.1 litres) is a bit conservative, and in fact there was more like 18.5-15.2 = 3.3 liters left. That's OK, as it means there is likely at bit of additional range.
This fillup got me 222.7 miles.
I am note usually this ANAL, but had let if run down to single bar several times before, but never far enough I guess to see the yellow gas light or flashing single bar, hence you can't see remaining fuel or distance. I just wanted to verify that it is working properly and it did exactly what the manual says it is supposed to do.
