Dashboard warning lights: What do they actually mean?

How well do you know your car? There is one symbol on the dashboard that, despite its visibility and obviousness, is often ignored. What does it mean?

Even drivers with many years of experience do not always know all the elements of their car. Efficient vehicle operation and a good feel for the car are not enough to become a true expert—things like icons on the dashboard also matter. Although everyone must memorize these icons before the driving test, this knowledge can fade.

At first glance, illuminated warning lights may not always signal that everything is fine with our car. The color of these symbols is essential and signals to the driver what they should pay attention to. If the icons light up in green, everything is good. Yellow lights, and even worse—red ones—should concern us. Immediate action is necessary to fix the issue and avoid additional stress and costs.

The most worrying symbols on the dashboard indicate a failure of the electrical system, driver assistance system, ABS, airbags, and braking system. Red warning lights signaling low oil levels, high coolant temperature, or worn brake pads are equally concerning. The fuel reserve indicator can also surprise us at the least expected moment.

If you often forget which side the fuel tank is on and only start wondering at the gas station, this dashboard light can be useful. Fuel reserve symbols often have a hidden message and are not just about fuel. Pay close attention to them during your next drive, as manufacturers include this hint for a specific reason.

Very often, next to the fuel reserve icon on the dashboard, there is a small arrow, which is not decoration. Depending on its position, you can easily remember the side of the fuel filler cap. This makes refueling much easier for the forgetful. However, if this arrow is absent, look at the hose drawing, which indicates the car's side of the fuel tank.
