How do I use the engine coolant temperature gauge?

The engine coolant temperature gauge is on your instrument control panel. It tells you the temperature of your engine. The gauge has an H for hot, and a C for cool. Where the needle rests between the H and the C lets you know how hot your vehicle’s engine is. If the vehicle is operating correctly, the needle won’t get very close to the H, or to the colored region near the H. If the needle indicates that the engine is too hot, you should pull over your vehicle as soon as possible.
