What it means What to do
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 an Alfa Romeo
Dealership.
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. 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 Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.
