Warning lights on panelMeaningWhat to do
HOT ENGINE COOLANT
The digital warning light switches on when the key is
turned to MAR-ON, but it should switch off after a few
seconds. The warning light turns on when the engine is
overheated.
The associated message appears on the display.
ALTERNATOR FAULT
The digital warning light comes one with the engine
running only when an alternator fault is detected.Contact a dedicated
Alfa Romeo Dealership as soon as possible.
In normal driving conditions: stop the car, switch off the
engine and check that the water 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.
Should the warning light turn on again at the next
start-up, contact a dedicated Alfa Romeo Dealership.
If the car is used under demanding conditions
(e.g. in high-performance driving): slow down and, if the
warning light stays on, stop the car.
Wait for 2 or 3 minutes with the engine running and
slightly accelerated to further favour the coolant
circulation. Then stop the engine.
Check that the coolant level is correct as described
above.
IMPORTANT On particularly demanding journeys, it is
advisable to keep the engine on and slightly accelerated
for a few minutes before switching it off.
