What is the purpose of my Mitsubishi Outlander glow plug light?

The main role of the engine glow plug light, which is generally symbolized by a yellow coil, is to ensure that your glow plugs are working correctly. In reality, it must light up when you switch on your Mitsubishi Outlander to tell you that they are heating the intake air in your cylinders and must go out after a few minutes when the engine is running. This preheat light is therefore not expected to stay or come on while driving with your car. But, if it comes on while driving, it may suggest different troubles, we will try to point out the most important ones.
