The needle indicates the amount of fuel left in the tank.The reserve warning light (A) turns on (on certain versions together with the message shown on the reconfigurable multifunction display) to indicate that 5 to 7 litres of fuel are left in the tank.
E - tank empty.
F - tank full (see contents of “At the filling station” paragraph in this chapter).
Do not travel with the fuel tank almost empty: the gaps in fuel delivery could damage the catalyst.
IMPORTANT If the needle reaches the (E) with warning light (A) flashing this means that there is a failure. Contact a Fiat Dealership.
