Alfa Romeo Giulia 2019 Repair Manual

Symbol What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The symbol lights up when the engine has overheated.
In normal driving conditions: stop the car, switch off the engine and check that the coolant level in the reservoir is not below the
MIN mark. In this case, wait for the engine to cool down, then slowly and carefully open the cap, top up with coolant and check that
the level is between the MIN and MAX marks on the reservoir itself. Also check visually for any fluid leaks. Contact an Alfa Romeo
Dealership if the symbol comes on when the engine is started again.
If the vehicle is used under demanding conditions (e.g. in high-performance driving):slow down and, if the warning light stays on,
stop the vehicle. Stop for 2 or 3 minutes with the engine running and slightly accelerated to facilitate better coolant circulation,
then turn the engine off. Check that the coolant level is correct as described above.
DOOR OPEN
The symbol switches on when one or more doors are not completely shut. An acoustic signal is activated with the doors open and
the car moving.
Close the doors properly.
BONNET NOT PROPERLY SHUT
The symbol turns on when the bonnet is not properly closed, along with the icon, an image of the vehicle with an open bonnet
appears on the display.
A buzzer is heard when the bonnet is open and the vehicle is moving.
Close the bonnet properly.
BOOT NOT PROPERLY SHUT
The symbol turns on when the boot is not properly closed, along with the icon, an image of the vehicle with an open boot appears on
the display.
A buzzer is heard when the boot is open and the vehicle is moving.
Close the boot properly.

SPEED LIMIT EXCEEDED
(where provided)
The symbol switches on when the speed limit of 74.5 mph (120 km/h) is exceeded.
IMPORTANT
18)Driving the vehicle with this symbol on may severely damage the gearbox, with resulting breakage. The oil may also overheat: contact with hot
engine or with exhaust components at high temperature could cause fires.

Symbol What it means
ENGINE IMMOBILIZER FAILURE / BREAK-IN ATTEMPT
Engine Immobilizer system failure
The symbol switches on to report a failure of the Engine Immobilizer system. Contact an Alfa Romeo Dealership as soon as
possible.
Break-in attempt
The symbol switches on when the ignition device is moved to ON position, to indicate a possible break-in attempt detected by the
alarm system.
Electronic key not recognised
The symbol switches on when the engine is started and the electronic key is not recognized by the system.
Alarm system failure
This symbol switches on to report an alarm system failure.
POSSIBLE ICE ON ROAD
The symbol turns on when the outside temperature is below or equal to 37.4°F (3°C).
ENGINE OIL DETERIORATED
(where provided)
The symbol is displayed only for a limited time.
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 an Alfa Romeo Dealership as soon as possible.
19)
IMPORTANT
19)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 may result in severe damage to the engine and invalidate the warranty. When this symbol comes on, it
does not mean that the level of engine oil is low, so you do not need to top up the engine oil.

Symbol What it means
LOW AdBlue® (UREA) DIESEL EMISSIONS ADDITIVE LEVEL WARNING (2.2 JTD versions only)
The AdBlue® (UREA) Diesel Emissions Additive low level symbol
A warning and a message indicating the need to top up AdBlue® (UREA) also appear on the display.
The symbol
stays on until the tank is topped up with at least 1.11 UK gal - 5 litres of AdBlue® (UREA).
If you do not top up, a specific message will appear on the instrument panel display whenever a certain threshold is reached until it
will no longer be possible to start the engine.
A message will appear permanently on the instrument panel and an acoustic tone will be heard when there is about 125 miles
(200 km) of range left.
A specific message will appear on the instrument panel display when there are 0 miles (0 km) of range left. It will no longer be
possible to restart the engine after it has been stopped. It will be possible to restart the engine after pouring at least 1.11 UK gal –
5 litres of AdBlue® (UREA) into the tank. Top up the AdBlue® (UREA) tank as soon as possible with at least 1.11 UK gal - 5 litres of
AdBlue® (UREA). If topping up is done with remaining range of AdBlue® (UREA) in the tank equal to 0 miles (0 zero), you may need to
wait 2 minutes before starting the engine.
20)

Symbol What it means
WATER IN DIESEL FILTER (Diesel versions)
The symbol switches on constantly when driving, along to indicate the presence of water in the diesel filter.21)
DPF CLEANING (particulate trap) in progress (diesel versions with DPF only)
The symbol comes on when the ignition device is brought to ON, but it should switch off after a few seconds.
The symbol switches on constantly to indicate that the DPF system needs to eliminate the trapped pollutants (particulate) through
the regeneration process.
The symbol does not switch on during every DPF regeneration, but only when driving conditions require that the driver is notified.
To turn off the symbol, keep the vehicle in motion until the regeneration process is over. The process normally takes about
15 minutes. Optimal conditions for completing the process are achieved by travelling at 37 mph (60 km/h) with engine speed
above 2000 rpm.
When this symbol switches on, it does not indicate a fault and thus it should not be taken to a workshop.
IMPORTANT
21)The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If thesymbol 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.
Symbol What it means
GPF (Gasoline Particulate Filter) CLEANING in progress (2.0 T4 MAir versions only)
The symbol comes on when the ignition device is brought to ON, but it should switch off after a few seconds.
The symbol switches on fixed, together with a dedicated message on the display, to indicate that the GPF system needs to
eliminate the trapped pollutants (particulate) by means of the regeneration process.
The symbol does not light up on during every GPF regeneration, but only when driving conditions require that the driver is notified.
To turn off the symbol, keep the vehicle in motion until the regeneration process is over. The optimal conditions for completing the
process are achieved by varying the speed of the car (pressure on the accelerator pedal). Hold a speed faster than 37 mph
(60 km/h), on extra-urban roads, until the symbol and the message disappear from the display.
When this symbol switches on, it does not indicate an anomaly and thus it should not be taken to a workshop.
