What is the role of my Suzuki Swift glow plug light?

The primary goal of the engine glow plug light, which is generally symbolized by a yellow coil, is to ensure that your glow plugs are working effectively. In reality, it must light up when you switch on your Suzuki Swift 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 vehicle.
