2016 Alfa Romeo Giulietta Fault light

Warning lights on
panelWhat it means What to do
redDEGRADED ENGINE OIL (for versions/markets, where provided)
The warning light will turn on flashing together with a dedicated message
on the display (for versions/markets where provided).
Depending on the versions, the warning light flashing modes are as
follows:
- for 1 minute every two hours;
- for 3 minute cycles with the warning light off for intervals of 5 seconds
until oil is changed.
After the initial warning, each time the engine is started up, the warning
light will continue to flash in the same mode, until the oil is changed. A
specific message will appear on the display (for versions/markets, where
provided) in addition to the warning light. If the warning light flashes, this
does not mean that there is a fault, but simply informs that it is now
necessary to change the oil as a result of regular use of the car. Engine oil
deterioration is accelerated by:
- mainly town use of the car which makes the DPF regeneration process
more frequent;
- use of the vehicle for short drives, in which the engine does not have
time to reach its regular operating temperature;
- repeated interruptions of the regeneration process, signalled by the DPF
warning light switching on.Contact an Alfa Romeo
Dealership as soon as
possible.65) 66)

driving, it means that the injection system is not working
properly. The warning light on constantly signals a
malfunction in the supply/ignition system which could
cause high exhaust emissions, a possible loss of
performance, poor driveability and high consumption.
On some versions, the display shows the dedicated
message. The warning light goes out after the fault
disappears: the indication is stored in the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the car with the
warning light on constantly may cause
damage.
Contact an Alfa Romeo Dealership as
soon as possible.
