ENGINE OIL DETERIORATED
(for versions/markets, where provided)
The digital warning light will flash and a specific message will appear on
the display (for versions/markets, where provided).
The digital warning light may flash in the following ways, depending on
the versions:
- 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 digital
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 digital
warning light flashes, this does not mean that the car is defective, but
simply informs the driver that it is now necessary to change the oil as a
result of regular vehicle use. Remember that the deterioration of engine
oil is accelerated by using the car for short drives, preventing the engine
from reaching operating temperature.Contact the dedicated
Alfa Romeo Dealership as
soon as possible.
