Coolant Temperature Low/High Light Warning
If this light is illuminated in BLUE, it is an indication that the engine has not been warmed up sufficiently. You should not begin driving your vehicle until the blue indicator light is removed. If it is blinking and RED, it means that the engine is close to overheating. A solid RED illumination indicates that the engine is overheating. If the continuous red, or blinking red indicators appear, you should stop your vehicle immediately and have your vehicle inspected.
