Fuel range is determined by ampunt f fule in the tank, Average Fuel economy over a pre determined time (Not what the average shows on the DIC, because when you reset your average MPG if you have not filled up your range will remain the same before and after you reset it.), Then it take in account the speed you are driving at NOW and the other operating peramitors and figures a range remaining.. I have foiund though it is never correct to what I can actually go. it is usually a higher number.. On my HHR i can usually tell how far I can go myself just by how i am driving and looking at the gas guage... Once you have owned a car for a while you can guestimate closer than the range will show...
