I’d say it’s about 1.5 to 2 gallons remaining in the tank when the low fuel chime kicks in and asks if you want to navigate to the nearest gas station. Now our old Jeep, when the low fuel light comes on that ****** was on fumes. Had it come on once and I drove about 20 miles to get off the highway to a gas station. I put 14.7 gallons in a 14.5 gallon tank.
