So is there 5 litres of fuel in the tank unused? YES YES YES I guess it is safety reason not to damage the engine.

No, I am sorry, but not exactly true. Maybe the light goes on, when 15 liters is still in there in rx400h. But you can not use 5 litres at all. I got RX450h and the light goes when 55 litres can be filled. But you can use only half of the rest 10 litres. To me the RX400h solution is better, because it is standart, that 10 litres is still there to use in the tank. Same as Mercedes etc...

Hi everyone, RX450h 3rd generation 5 liters (1.5gal) of fuel tank capacity can not be used at all for engine safety reasons. There is only 60 (15,8gal) litres of real tank "capacity". The light goes on when 10 litres left BUT it means only 5 litres you can use - 60 km (37miles). I know that for sure. I ran out of fuel yesterday. The combustion engine stopped. EV went on for few hundred meters. I put 5 litres in tank. Went to nearest gas station and fill the tank until full - 55 litres. So 75 miles from the moment when light comes up is NOT TRUE. It is half - 37 miles.
