The exact amount of petrol remaining in a Ford Fiesta Chicane's fuel tank when the low fuel warning light illuminates isn't a fixed number. It varies slightly depending on driving style and the car's individual sensors. However, it's generally accepted that you have
between 1 and 2 gallons (4.5 to 9 litres) left.
It's best to refuel as soon as the light comes on to avoid running out of fuel completely.
