An engine-temperature warning can indicate overheating. Continued operation may damage the engine, so pull over safely, switch it off, and follow the overheating instructions in the owner's manual.
Do not remove a hot radiator or coolant-reservoir pressure cap. Stay clear of steam and allow the system to cool. A warning that disappears after cooling does not establish that the underlying cause has been corrected.
Arrange assistance when needed and contact The Car Clinic of Miami with the gauge reading, warning message, and any visible leakage. Do not restart the engine simply to demonstrate the symptom.
