7 warning lights on cars that drivers cannot ignore
(Baonghean.vn) - Modern cars can have dozens of control systems integrated with warning lights when there is an abnormality. Drivers may not remember all of them, but it is essential to remember the following hazard warning lights.
1. Brake system warning light
 |
| When this light comes on, there can be many causes, from worn brake pads to a leak in the oil line that causes a lack of brake fluid. Accompanying signs may be a softer than normal brake pedal feel or even no brake response. A feeling of a receding brake pedal can also be caused by a broken brake cup, reducing or losing brake fluid pressure. |
2. Engine fault check warning
 |
| When this light is on, there is an error inside the engine, you need to take the car to a reputable service to check and handle. It could be due to the oxygen sensor system not working, the wind measuring system is broken... Sometimes, the danger level may not be high, but it can increase fuel consumption by up to 30%. |
3. Tire pressure warning
 |
| The light will come on when any tire is 25% below the standard pressure. Driving with less than the recommended pressure increases the risk of a blowout. Underinflated tires also cause uneven braking and traction. This increases frictional resistance and fuel consumption. The cause may be a puncture or air leakage over time. On average, tire pressure drops by 0.07 - 0.14 atmospheres. However, sometimes it can also be due to a faulty tire pressure sensor. Check and add air according to the recommendations on the tire sidewall. |
4. Lubricating oil pressure warning
 |
| This sign indicates that the engine's lubricating oil pressure is low, which is not enough to ensure safe engine operation. Intentionally driving in such a condition can cause serious engine damage because the metal surfaces that move relatively are scratched... Low pressure can be due to lack of oil, oil that is too thin, worn bearings that cannot maintain system pressure, or a broken oil pressure gauge. |
5. Coolant temperature warning
 |
| When the "TEMP" light is on, it means the engine is overheating. The parts expand too much, causing them to get stuck or broken, such as piston scratches, valve wear, cylinder gasket blowout, or cylinder deformation... When you pull the car to the side of the road, you may see water leaking out from the gap in the radiator or hot pipe. Pay attention to the water level in the auxiliary tank. Never open the radiator cap or auxiliary tank when the engine is still hot because the water may overflow and cause burns. Using the right type of coolant helps the engine operate more stably and durably. |
6. Airbag system warning
 |
| The airbag control system may stop working, and the airbag may not deploy in the event of a collision. The cause on some vehicles is sometimes very simple, it may just be due to poor contact with the connector pins. |
7.Battery charging indicator light
 |
| This is a sign that the vehicle's alternator is not working properly or is not working at all, possibly due to damage or a loose or broken alternator drive belt or, in the worst case, a burnt alternator. The vehicle will still run normally and use the remaining electrical energy in the battery. |
