Why Do Dashboard Warning Lights Stay On?

The dashboard warning lights will not come on unless a malfunction occurs. However, they come on to inform you in case of a malfunction in your vehicle. The main problem here is how well you know the source and importance of the malfunction.

First, let's examine the lights in main groups. If we divide them into 3 main groups, the lights consist of red, yellow and green colors. The color differences here indicate the level of importance. If a red light comes on in your car and stays on all the time, this will cause more serious problems. The same applies to yellow lights. These 2 colors affect the driving of warning lights.

Red and yellow warning lights usually cover problems that users cannot solve. You may need help from a service station or an experienced mechanic.

This warning sign will remain on as long as you do not top up the wash water.

Why do dashboard warning lights stay on? You may wonder. However, not putting the washer fluid does not prevent you from traveling with the vehicle. The warning light is illuminated by the vehicle to tell you "there is such a deficiency, you should fix it".

The only way to do how to reset dashboard warning lights is to fix the existing malfunction. If the warning light is still on in your vehicle when you fix a malfunction, you will be asked to identify it. For example: the tire pressure warning light is indicated by the color yellow.

This warning light informs you that there is a pressure change in the tires during sudden weather changes in summer or winter. In this case, the light will not go out immediately when you fulfill the pressure settings recommended by the factory. Even if this is automatically detected in new vehicles, manual operation is required in most vehicles.

Enter the multimedia section of your vehicle and click on the vehicle maintenance - repair tab. Here you will see the menu related to tire pressures. You should save your current tire pressure settings via this menu. After you do this, the current tire pressure settings will be saved by the vehicle.

When you see the tire pressure warning sign on the dashboard, you can understand that a different value has occurred from the last values you set.

This is an example we have given about tire pressure settings in most vehicles. However, warning lights such as fuel, seat belt, battery charging, general engine failure should go out when the fault is fixed by the system.

If you repair the fault at the service station, the service will clear the warning lights for you. However, if you have not had your vehicle serviced at a station other than the service station and the warning light remains on in your vehicle, pay attention. The fault may not have been fixed.
