Drivers are alerted to the presence of a fault various systems car using . It is not always possible to decipher the meaning of such burning icons intuitively, since not all car enthusiasts are well versed in cars. In addition, on different cars, the graphic designation of one icon itself may differ. It is worth noting that not every light on the panel only indicates a critical malfunction. The indication of light bulbs under the icons is divided into 3 groups by color:
Red icons they indicate danger, and if any symbol lights up in this color, you should pay attention to the signal from the on-board computer in order to take measures to quickly resolve the malfunction. Sometimes they are not so critical, and it is possible to continue driving the car when such an icon on the panel is on, but sometimes it is not worth it.
Basic icons on the dashboard
Yellow indicators warn of a malfunction or the need to take some action to drive the car or service it.
Green indicator lights inform about the vehicle’s service functions and their activity.
Let's present a list of the most frequently asked questions and an explanation of what the burning icon on the panel means.
Information icons
Car icon The lights may vary, sometimes the “car with a wrench” icon, the “car with a lock” icon, or an exclamation mark are on. About all these notations in order:
When this indicator is on ( car with key), then it informs about malfunctions in the engine (often a malfunction of some sensor) or the electronic part of the transmission. To find out the exact cause you will need to perform.
caught fire red car with lock, this means that problems have arisen in the operation of the standard anti-theft system and it will be impossible to start the car, but if this icon blinks when the car is locked, then everything is normal - the car is locked.
Yellow car indicator with exclamation mark notifies the driver of a car with a hybrid engine about a malfunction of the electric drive. Resetting the error by disconnecting the battery terminal will not solve the problem - diagnostics are needed.
Open door icon Everyone is used to seeing it on when a door or trunk lid is open, but if all the doors are closed and the light on one or four doors continues to shine, then often the problem should be looked for in the door end switches (wire contacts).
It begins to flash when the vehicle stability control system detects a section of a slippery road and is activated to prevent slipping by reducing engine power and braking the slipping wheel. There is no need to worry in such a situation. But when a key, a triangle or a crossed out skid icon appears near such an indicator, it means the stabilization system is faulty.
Pops up on the scoreboard when it's time to produce maintenance car. It is an information indicator even after maintenance.
Warning icons on the panel
steering wheel icon Can light up in two colors. If the yellow steering wheel is on, then adaptation is required, and when a red image of the steering wheel with an exclamation mark appears, you should already be concerned about the failure of the power steering or power steering system. When the red steering wheel lights up, your steering wheel will probably become very difficult to turn.
As a rule, it blinks if the car is closed; in this case, the indicator of a red car with a white key signals the operation of the anti-theft system. But there are 3 main reasons if the immo light is constantly on: it is not activated, if the tag on the key is not read or the anti-theft system is faulty.
It lights up not only when the handbrake lever is activated (raised), but also in cases where the brake pads are worn out or need refilling. On a car with an electronic handbrake, the parking brake light may come on due to a glitch in the limit switch or sensor.
It has several options and depending on which one is on, draw conclusions about the problem accordingly. One red lamp with a thermometer scale indicates an increased temperature in the engine cooling system, but a yellow expansion tank with waves indicates a low coolant level in the system. But it’s worth considering that the coolant lamp does not always light up when the level is low, perhaps it’s just a “glitch” of the sensor or float in the expansion tank.
Indicates a low fluid level in the windshield washer expansion tank. Such an indicator lights up not only when the level actually decreases, but also if the level sensor is clogged (the sensor contacts become coated due to poor-quality liquid), giving a false signal. On some vehicles, the level sensor is triggered when the washer fluid does not meet specifications.
– this is an indicator of the Anti-Spin Regulation system. The electronic unit of this system works in tandem with ABS sensors. When such a light is constantly on, it means the ASR is not working. On different cars, such an icon may look different, but often in the form of an exclamation mark in a triangle with an arrow around it or the inscription itself, or in the form of a car on a slippery road.
According to information from the manual, it indicates a malfunction in the exhaust gas purification system, but, as a rule, such a light starts to light after poor refueling or the presence of an error in the sensor. The system registers misfires of the mixture, as a result of which the content of harmful substances in the exhaust gases increases and, as a result, the “exhaust gases” light comes on on the dashboard. The problem is not critical, but diagnostics are worth doing to find out the cause.
Reporting a malfunction
Lights up if the voltage in the on-board network drops, often this problem is associated with a lack of charge battery from generator, so it can also be called “generator icon”. On vehicles with a hybrid engine, this indicator is supplemented by the inscription “MAIN” at the bottom.
It is also a red oil can - indicates a drop in the oil level in the car engine. This icon lights up when you start the engine, and does not go out after a few seconds or may light up while driving. This fact indicates problems in the lubrication system or a drop in oil level or pressure. The oil icon on the panel may have a droplet or waves at the bottom; on some cars the indicator is supplemented with the inscription min, senso, oil level (yellow inscriptions) or simply the letters L and H (characterizing low and high level oils).
It can light up in several ways: both the red inscription SRS and AIRBAG, and “red man wearing a seat belt”, and a circle in front of him. When one of these icons is lit on the panel, it is on-board computer notifies you of a malfunction in the passive safety system, and in the event of an accident, the airbags will not deploy. Read the article on the website for the reasons why the airbag sign lights up and how to fix the problem.
Icon exclamation mark may look different and its meanings will accordingly also be different. So, for example, when the red (!) light is on in the circle, this indicates a malfunction of the brake system and it is advisable not to continue driving until the cause of its occurrence is determined. They can be very different: the handbrake is up, the brake pads are worn out, or the brake fluid level has dropped. A low level is precisely what poses a danger, because the reason may not only be in heavily worn pads, as a result of which, when you press the pedal, the fluid disperses throughout the system, and the float gives a signal about a low level, the brake hose may be damaged somewhere, and this is much more serious. Although, very often the exclamation mark lights up if the float (level sensor) is faulty or shorted, and then it simply lies. On some cars, the exclamation mark is accompanied by the words “BRAKE”, but this does not change the essence of the problem.
More exclamation mark may light up in the form of an “attention” sign, both on a red and yellow background. When the yellow “attention” sign lights up, it informs about a malfunction in the electronic stabilization system, and if it is on a red background, it simply warns the driver about something, and, as a rule, explanatory text lights up on the dashboard display or is combined with other informative text designation.
ABS icon may have several display options on the dashboard, but regardless of this, it means the same thing on all cars - the occurrence of a problem in the ABS system, and that in at the moment The anti-lock wheel system does not work. You can find out the reasons in our article. In this case, movement can be made, but there is no need to rely on the ABS to activate; the brakes will operate as usual.
It can either light up periodically or burn constantly. A light with this inscription indicates problems with the stabilization system. The Electronic Stability Program indicator, as a rule, lights up for one of two reasons - either the rotation angle sensor has failed, or the brake light sensor (aka “frog”) has died for a long time. Although, there can be a more serious problem, for example, the brake system pressure sensor is covered.
Some drivers may call it the “injector icon” or may light up yellow when the engine is running. It informs about the presence of engine errors and malfunctions electronic systems. To determine the reason for its appearance on the dashboard display, self-diagnosis or computer diagnostics are performed.
Glow plug icon may light up on the dashboard of a diesel car, the meaning of such an indicator is exactly the same as the “check” icon on gasoline cars. When there are no errors in the electronic unit’s memory, the spiral icon should go out after the engine warms up and the glow plugs are turned off. How to check glow plugs.
This material is informative for most car owners. And although absolutely all possible icons of all existing cars are not presented here, you will be able to independently understand the main symbols of the car’s dashboard, and will not sound the alarm when you see that the icon on the panel is on again.
