Nevada is correct. Many Toyota Hybrid models suffer from tanks that do not seem to hold the “specified” amount of fuel. It would be wise to reserve at least 2 gallons based on what I have seen. This has been a Toyota thing for decades. My 1979 Toyota Supra ran out of fuel at 3/4s of a tank shortly after I bought it.
