Kia Optima: Engine Temperature GaugeThis gauge shows the temperature of the engine coolant when the ignition switch is ON.
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. If your vehicle overheats, refer to “Overheating’’ in the Index.
