Warning lights on
panelWhat it means What to do
LOW ENGINE OIL PRESSURE
When the key is turned to MAR the warning light comes on, but should go out as soon
as the engine is started.
After turning the ignition key to MAR, wait for about 2 seconds before starting the
engine.
The warning light switches on constantly together with a message on the display
(where provided) when the system detects that engine oil pressure is low.
IMPORTANT Do not use the vehicle until the failure has been solved.
IMPORTANT To find out the correct oil quantity, always check using the dipstick.
13)
DEGRADED ENGINE OIL (where provided)
The warning light will turn on flashing and, on some versions, with a specific message
on the display.
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. On some versions, the
display shows a dedicated message together with 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.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
WATER IN DIESEL FILTER (Diesel versions)
The warning light switches on constantly when driving to indicate
the presence of water in the diesel filter.
15)
DPF CLEANING (particulate trap) in progress (diesel versions
with DPF only)
The warning light switches on when the ignition key is turned to
MAR, but it should switch off after a few seconds. The warning
light switches on constantly to indicate that the DPF system
needs to eliminate the trapped pollutants (particulate) through
the regeneration process.
The warning light does not come on during every DPF
regeneration, but only when driving conditions require that the
driver is notified. To turn off the warning light, keep the car in
motion until the regeneration process is over.
On average, the process lasts 15 minutes. Optimal conditions for
completing the process are achieved by travelling at 60 km/h
with engine speed above 2000 rpm.
When this warning light switches on, it does not indicate a vehicle
failure and thus it should not be taken to a workshop.

WARNING
23)If thewarning light does not switch on when the ignition device is moved to ON or if it stays on when driving (together with the message on
the display), there might be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked
immediately.
24)A fault with the warning light
is signalled by illumination of the iconon the instrument panel display and by the flashing of passenger
airbag disabled warning light on the rearview mirror. In addition, the airbag system automatically disables the passenger side airbag (where
provided). In this case, the warning light may not indicate any faults with the restraint systems. Before proceeding, contact an Alfa Romeo
Dealership to have the system checked immediately.
25)If the warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from the first
switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember
that when this 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.
26)If the warning light flashes with the car in motion, contact an Alfa Romeo Dealership.
27)Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine may be switched off even if the
warning light is on: repeated interruptions of the regeneration process could cause an early deterioration of engine oil. For this reason it is
always advisable to wait for the symbol to go off before turning off the engine, following the instructions above. Do not complete the DPF
regeneration process when the vehicle is stopped.
IMPORTANT
13)If thewarning light switches on when driving, stop the engine immediately and contact an Alfa Romeo Dealership.
14)If, turning the ignition device to MAR, the warning lightdoes not turn on or if it turns on steadily or flashing when travelling (on some
versions together with the message on the display), contact an Alfa Romeo Dealership as soon as possible.
15)The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If the
symbol is displayed contact an Alfa Romeo Dealership as soon as possible to bleed the system. If the above indications come on immediately
after refuelling, water has probably been introduced into the tank: stop the engine immediately and contact an Alfa Romeo Dealership.
