What is the goal of my Chevrolet Trax glow plug light?

The main intent of the engine glow plug light, which is in most cases represented by a yellow coil, is to assure that your glow plugs are working effectively. In reality, it must light up when you switch on your Chevrolet Trax 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 turns on while driving, it may suggest several issues, we will try to point out the most important ones.
