The needle shows the fuel present in the tank. When the fuel reserve warning light A-fig. 35 - 36 comes on (on certain versions with the dedicated message on the reconfigurable multifunction display) it means that there are approximately 5-7 liters of fuel left in the tank.
E - tank empty.
F - tank full.
Never travel with the tank almost empty: lack of fuel could damage the catalyser.

IMPORTANT
The needle will point to E and the reserve warning light A will flash to indicate a fault in the system. Contact a Fiat Dealership to have the system checked.
