What is the role of my Lincoln MKX glow plug light?

The main intent of the engine glow plug light, which is generally symbolized by a yellow coil, is to assure that your glow plugs are working properly. In fact, it must light up when you switch on your Lincoln MKX 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 meant to stay or come on while driving with your vehicle. However, if it turns on while driving, it may suggest multiple troubles, we will try to describe the most important ones.
