Warning lights on panelMeaningWhat to do
LOW ENGINE OIL PRESSURE
When the key is turned to MAR, the digital warning light
switches on, but it should switch off as soon as the engine
is started. The digital warning light switches on constantly
together with the message in the display when the system
detects that the engine oil pressure is insufficient.
DETERIORATED ENGINE OIL
(where provided)
The digital warning light will turn on flashing and (on some
versions) with a specific message on the display.
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. In addition to the
warning light the display will also show an associated
message (on some versions). 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.

20)If, when the key is turned to MAR, the ¬warning light does not come on or if it stays on with the vehicle in motion (together with the
message on the display) there could be a failure in the safety systems; under these circumstances the airbags or pretensioners may not be
triggered in the event of an impact or, more rarely, they could be triggered accidentally. Before proceeding, contact a dedicated Alfa Romeo
Dealership to have the system checked immediately.
21)Failure of the
¬warning light is signalled by the flashing for longer than the usual 4 seconds of the “warning light. In addition, the airbag
system automatically disables the passenger side airbag. In this case, the ¬warning light may not indicate failures in the retaining systems.
Before proceeding, contact a dedicated Alfa Romeo Dealership to have the system checked immediately.
22)A failure of the
“warning light is indicated by the ¬warning light. In addition, the airbag system automatically disables the passenger
side airbag.
23)Deteriorated engine oil should be replaced as soon as possible after the digital warning light comes on, and never more than 500 km after it
first switches on. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember that when the
digital warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you must not top up the engine oil.
24)If the warning light flashes with the car in motion, contact the dedicated Alfa Romeo Dealership.
