There isn't a fuel gauge on a F4i. The only time you know how low you are on fuel is when you are in the reserve and have about 40 miles to go. I reset my trip every time I fill up and fill up with the same amount of fuel (3 gallons) so when I get to around 120 miles I know its time to start looking for a gas station.

No, you don't need to flip a lever or anything for reserve. It works like a car.
