Your car’s safety is flickering :
Read the dashboard warning lights properly!

The dashboard full of various colored lights blinking such as green, yellow and red are like traffic lights. The green light indicates that the device is working properly, while the yellow and red lights are warning signs against risks. The lights are valuable and important whispers of warnings given by our car! Let’s listen to them.

Yellow warning light - “Check the car!”

The ‘yellow warning light’ is turned on when a certain part has a defect and thus requires inspection even though it is not directly relevant with driving at the moment. Even though it’s not an immediate threat to the driver, it may lead to a bigger problem if left as it stands. That’s why you should check the relevant part as soon as possible if the yellow warning light is on.

1) Engine warning light
This light goes on when there’s a problem with the engine. It indicates that perhaps air went into the engine while putting gas in, or there is something wrong with the engine control unit or emission control sensor. Since this warns you of trouble with the engine, which is the heart of vehicles, you should visit an auto repair shop immediately if this light comes on.

2) TPMS warning light
The TPMS(Tire Pressure Monitoring System) warning light, which checks the tire pressure by itself and notifies the driver, is turned on when the pressure is too low, but then it sometimes automatically turns off if the tire pressure increases, depending on the outdoor temperature. If the TPMS warning light is constantly turned on, this means the tire is flattened, so you must check the pressure.

3) Immobilizer warning light
An immobilizer is an Anti-theft system that starts the car only when the unique password is consistent between the smart key and the engine. Since the device keeps you from starting the car through indirect manipulation without using a smart key, this light comes on if the smart key is not inside the car, and therefore the car won’t start.

4) ESC warning light
ESC(Electronic stability control) is also referred to as VDC(Vehicle dynamic control), ESP(Electronic stability program), and many others depending on the vehicle, and it’s a safety system that keeps the car from skidding. Brake pressure and engine output are controlled by detecting the skidding. If there’s something wrong and this light is on, your car is likely to skid on wet roads, so stop by the repair shop to check it out.

5) ABS warning light
ABS(Anti-lock brake system) is a system that keeps the driver from losing car coordination by maintaining the tire rotation in emergency braking. This is usually turned on when you start the car and then turns off automatically. If the ABS warning light is turned on while driving or is not turned on even after starting the car, this means there’s something wrong with the ABS, which will increase the braking distance of the car, and thus it requires proper attention.

Red warning light - “WARNING, you’re in danger!”

The ‘red warning light’ indicates an emergency. In other words, there’s a high risk of an accident because there’s something wrong with a component that is directly related to driving. Thus, if the ‘red warning light’ comes on, stop driving immediately and park the car in a safe place, and then solve the problem quickly.

1) Brake warning light You may have seen the brake warning light many times whenever you started the car, but not remembering that the handbrake has been enabled. If the light doesn’t go off even after disabling the handbrake, it’s highly likely that there’s not enough brake oil or the relevant component is worn out, so you must immediately check the amount of brake oil and fill it up.

2) Engine oil warning light
The engine oil warning light comes on if the oil pressure is low due to a lack of engine oil or if the oil pump is broken. You must first check the amount of engine oil and fill it up if necessary. If there’s enough engine oil and the warning light still stays on, find a repair shop and check other components like the oil pump.

3) Battery warning light
The battery warning light indicates that the battery is dead or the charging system is broken. It also comes on if there’s something wrong with other components such as the fan belt that turns the fans inside the car. If you continue to drive with the warning light still on, the battery might die or become overheated, which may even damage the radiator fan. If the fan belt is broken, your car must be towed.

4) Coolant temperature warning light
If the coolant temperature is higher than 120 degrees and this warning light came on, it’s likely that you ignore this warning and continue driving, the engine room will produce smoke and cause trouble with driving. Thus, turn off the engine to cool it off, or check the remaining amount of coolant after sufficiently cooling off the engine and fill it up.

5) Seat belt warning light
Wherever you sit in a car, you must always put on your seat belt. Just as the warning light goes off the moment you put on the seat belt, turn off your safety ignorance as well. Don’t forget that the seat belt saves your life!

Warning lights allow you to communicate with your car without words!
The warning lights flicker to tell you whether your car is currently in a sound state, is anxious, or is on the verge of exploding. So check these lights constantly to enjoy safer and more pleasant driving.
