Engine Coolant Temperature Sensor
In this manual: Convenient Features of Your Vehicle
~1min read

This gauge shows the engine coolant temperature when the ignition switch or engine start/stop button is in the ON position.
CAUTION
If the gauge pointer moves beyond the normal range toward the "H" position, it indicates overheating, which may damage the engine. Do not continue driving with an overheated engine.
WARNING
Never remove the radiator cap when the engine is hot. Engine coolant is under pressure and may cause severe scalding. Wait until the engine has cooled before adding coolant to the reservoir.
