The modern car is a complex mechanism controlled by electronics, which constantly monitors hundreds of parameters of the system. The dashboard serves as the main channel of communication between the driver and the “brain” of the car, instantly responding to any changes in the normal modes of operation. When one or the other lights up indicatorThis is a signal that the system has switched to active mode or, conversely, has detected a malfunction requiring intervention.
Many drivers ignore flashing symbols until the problem becomes apparent by ear or by the behavior of the car, often resulting in costly repairs. Understanding what it means placardThis prevents serious damage at an early stage of its occurrence. In this article, we will discuss color coding, critical and warning signs, and specific indicators of different brands.
Knowing the designations is not just theoretical background information, but a necessary skill for safe driving. If you see a burning red symbol, it almost always requires an immediate stop, whereas yellow or orange indicates a need for a scheduled call to the service soon.
Color classification of indicators
All car manufacturers adhere to the international standard of color coding, which allows the driver to instantly assess the degree of danger of the situation. Red is always associated with a critical malfunction or emergency. If the panel caught fire red-lightThis means that further movement can be life-threatening or lead to the complete failure of the unit.
Yellow or orange indicates a warning or maintenance requirement. Unlike red lights, when you burn. yellow-plate The vehicle usually retains the ability to move, but operation in this mode should be limited to the journey to the nearest service. The green and blue lights are informative and indicate that a system is activated, such as passing lights or cruise control.
⚠️ Never ignore flashing red indicators, such as oil pressure or coolant temperature. Continuation of movement with burning oil is guaranteed to lead to major repairs of the engine.
It is important to distinguish between the constant light of the indicator and its flashing mode. Often, flashing indicates a more serious problem than just a light bulb. Like flashing Check Engine This indicates ignition failures that can quickly destroy the catalyst.
Critical indicators of red
The most important symbol group is the red lights, which require an immediate response from the driver. The first indicator on the list is always the oil pressure indicator, often referred to as “oil”. Its tanning means that the pressure in the lubrication system has dropped below a critical level, and the rubbing parts of the engine may be left unprotected. The second most important indicator is the temperature of the coolant, which reports the engine overheating.
Also critical is the indicator of charging the battery. It lights up when the generator stops producing current, and the car runs exclusively on battery charge. In this case, power-system The vehicle is in danger of being completely shut down, which will cause the engine to stop, as modern ignition and injection systems require electricity.
- 🛑 Oil pressure: It requires immediate stop and check the oil level with a probe.
- 🌡️ Overheating: It is necessary to stop the car, let it cool down and check the level of antifreeze in the expansion tank.
- 🔋 Battery: Turn off energy-intensive appliances (oven, headlights) and move to the service.
- 🛑 Stop light: Some cars have a red STOP sign that requires an urgent stop.
If the "Olislenka" caught fire, do not try to reach the service on your own, even if the engine works smoothly. Call a tow truck to avoid jamming the crankshaft.
Another important red symbol is the exclamation point in a circle, often surrounded by a discontinuous line. This is a brake indicator. It can light up with the hand brake lowered, but if it burns with the "handle" lowered, then the system has a critically low level of brake fluid or depressurization of the contours.
Yellow warning signals
Yellow indicators are less dramatic, but you should not ignore them for a long time either. The most famous of them is Check Engine (check the engine). It lights up when the electronic control unit detects an error in the operation of the engine. The reasons can be very different: from poor-quality fuel to problems with the lambda probe or ignition system.
Another common yellow symbol is the ABS (anti-lock brake system) icon. If it burns, it means that the ABS system is disabled due to a faulty sensor or pump. The brakes are working normally, but the function of preventing wheel locking during emergency braking is inactive, which requires more careful driving.
Why is the ESP burning?
The ESP/ESC indicator can light up for two reasons. If it blinks while it is moving, the system works by correcting the trajectory. If the fire is constantly burning, the system is faulty or forced to shut down by the driver.
It is also worth paying attention to the fuel level indicator. When a yellow lamp lights up, it is a signal that less than 10-15% of the fuel is left in the tank. Long-term driving "on steam" can lead to failure of the gas pump, which is cooled by fuel, or to clogging of the fuel filter with particles from the bottom of the tank.
⚠️ Note: If the ABS indicator burns constantly, remember that during emergency braking, the wheels can lock, and the car will go Yuz. Increase the distance to the transport ahead.
Indicators of safety and comfort systems
Modern cars are equipped with many driver assistance systems, each of which has its own unique features. panel. The Airbag Indicator (SRS/Airbag) reports the status of the system. If it lights up at launch and goes out after a few seconds, it’s okay. If it burns constantly or flashes, then the passive safety system will not work in the event of an accident.
Special attention should be paid to the indicators associated with wheels. The tire pressure monitoring system (TPMS) signals with a yellow icon depicting the tyre section with an exclamation mark. This is a warning that the pressure in one or more tires has fallen below normal, affecting fuel consumption, rubber wear and driving safety.
| Name of system | Designation | Colour | Action of the driver |
|---|---|---|---|
| Airbags (SRS) | Sitting man with a circle | Red/Yellow | Diagnostics of the system |
| The anti-skid system | Vehicle and tracks | Yellow | Speed reset, road checks |
| Tyre pressure. | Tire section (!) | Yellow | Pump pressure check |
| Start-Stop System | Letter A in a circle | Green/Yellow | No (informational) |
Indicators of the stability system (ESP, DSC, VSA) are also often found on panels. Their active state (blinking) indicates that the car is at the limit of traction with the road, and the electronics slow down certain wheels to stabilize the trajectory. Constant burning indicates a system shutdown or malfunction.
The SRS (Airbag) indicator is one of the most important. If it burns constantly, the pillows may not open on impact or, worse, open spontaneously.
Seasonal and specific designations
In winter, indicators related to temperature and environmental conditions become relevant. The blue thermometer icon or snowflake on the dashboard often light up at air temperatures below +4 ... +5 ° C, warning of possible ice. This is not a fault, but a useful reminder to slow down.
Also, drivers may encounter an indicator of windshield heating (curving arrows up) or rear window heating (rectangle with ascending lines). Activation of these functions increases the load on the generator, which should be taken into account when driving at low engine speeds.
- ❄️ Snowflake: Ice warning (temperature around 0°C).
- 💧 The wipers: Low levels of washing fluid (often blue watering).
- 🌫️ Fog: Green fog lamp badges (front and rear).
- 🚗 Door: One of the doors or trunk (car diagram) is not closed.
There are less well-known but important indicators. For example, the particulate filter icon (DPF) on diesel cars. Its sunbathing indicates the need for filter regeneration, for which you need to travel several kilometers at high speeds. Ignoring this signal can lead to costly replacement of the node.
Specificity of designations from different manufacturers
Although most symbols are standardized, some automakers are introducing their own designations or changing the color scheme of the usual indicators. For example, in cars. BMW and Mercedes-Benz A complex message system is used on the display, where text information duplicates or replaces classical light bulbs.
In cars. Toyota and Lexus There are often specific icons of the hybrid installation, such as the “Ready” indicating the readiness of the electric car to move, or the indicator of the battery status of the HV. While in VAG (Volkswagen, Audi) special attention is paid to the indication of the turbine and injection systems.
☑️ What to do when you burn an unknown indicator
For accurate decoding of rare symbols, it is best to use official documentation. In the menu of the on-board computer of many modern cars (for example, Kia, Hyundai) there is a section called “User Guide” where you can find an interactive list of all icons specifically for your model.
⚠️ Note: Do not rely on “people’s councils” or forums to decipher specific indicators. A mistake in interpreting the "Brake System" symbol on some models can cost lives.
Frequently Asked Questions (FAQ)
What to do if the Check Engine is on fire, but the car is going normally?
If the indicator is lit with a smooth yellow light and the behavior of the car has not changed, you can carefully drive to the service. Check if the gas tank lid is tightly closed. If the indicator flashes or there are extraneous sounds / vibrations, stop immediately and call the tow truck.
Why does the battery light up when the car is running?
This means that the battery is not charged. Most likely, the generator or tension belt is defective. The car operates only on a battery charge, which is enough for 20-50 km of the way, after which the engine will stall.
Can I drive if the ABS indicator is on?
Yes, you can go, because the main braking system is good. However, it should be remembered that with a sharp braking, the wheels can be blocked, and the car will lose controllability. Move with extreme caution.
What does a flashing oil mean?
The flashing oil pressure indicator is a critical signal. Pressure has dropped to a dangerous low. Further operation of the engine will lead to the turning of the liners and major repairs. It requires an immediate stop.
Where can I find the exact decoding of the icons for my model car?
The most reliable source is the manual (manual), which comes with the car. Also, information can be found on the official websites of manufacturers or in the menu of the onboard computer in the "Help" section.
