What is the purpose of my Nissan Juke glow plug light?

The main purpose of the engine glow plug light, which is most of the time represented by a yellow coil, is to ensure that your glow plugs are working properly. Indeed, it must light up when you switch on your Nissan Juke 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 automobile. Nevertheless, if it turns on while driving, it may show multiple issues, we will try to point out the most important ones.
