This gauge indicates the temperature of the engine coolant when the ignition switch is in the ON position.
NOTICE
If the gauge pointer moves beyond the normal range area toward the “130 or H” position, it indicates overheating that may damage the engine.
Do not continue driving with an overheated engine. If your vehicle overheats, refer to "If the Engine Overheats" in chapter 6.
WARNING
Never remove the radiator cap when the engine is hot. The engine coolant is under pressure and could cause severe burns. Wait until the engine is cool before adding coolant to the reservoir.
