Warning light What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light switches on (on some versions together with a message and a symbol on the display)
when the engine is overheated. The display shows the dedicated message.
When driving normally: stop the vehicle, switch off the engine and check that the water level in the
reservoir is not below the MIN mark. If it is, 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.
Also check visually for any fluid leaks. If, when restarting, the warning light switches on (or the symbol is
displayed) again, contact a Fiat 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. Stop for 2 or 3 minutes with the engine running and slightly
accelerated to promote a better 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.
