This gauge indicates the temperature of the engine coolant when the ignition switch or Engine Start/Stop button is ON.
CAUTION
If the gauge pointer moves beyond the normal range area toward the "H" position, it indicates overheating that may damage the engine. Do not continue driving with an overheated engine.
WARNING
Never remove the radiator cap when the engine is hot. The engine coolant is under pressure and could severely burn. Wait until the engine is cool before adding coolant to the reservoir.
