Symbol
21) Deteriorated engine oil should be replaced as soon as possible after the symbol is switched on, and never more than 500 km after it first
switches on. Failure to observe the above indications may result in severe damage to the engine and invalidate the warranty. The switching
on of this symbol is not correlated to the quantity of oil in the engine; therefore if it flashes you do not need to top up the engine oil.
22) If the symbol flashes whilst driving, contact a Fiat Dealership.

FUEL LEVEL SENSOR FAILURE
The symbol switches on in the event of fuel level sensor failure. Contact a Fiat Dealership.
ENGINE OIL DETERIORATED
(where provided)
Diesel versions: the symbol turns on and is displayed for 3 minute cycles and intervals of 5 seconds until
the oil is changed.
The symbol is displayed until the problem is solved.
Petrol versions: the symbol switches on and then is not displayed when the display cycle is completed.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on
as described above until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is
now necessary to change the oil as a result of regular use of the vehicle.
The deterioration of engine oil is accelerated by using the vehicle for short drives, preventing the engine
from reaching operating temperature.
Contact a Fiat Dealership as soon as possible.
