What Do the Symbols on the Dashboard Mean?

Dashboard indicator lights are divided into three categories, representing indicators, warnings, and faults. The first category includes the most common indicator lights encountered during normal driving, such as light signal indicators, turn signal indicators, parking lights, etc. Their function is to indicate the status of various vehicle functions. The second category consists of warning lights, which serve an alerting function, such as the fuel indicator, door status indicator, seat belt indicator, etc. Typically, warning lights turn off after the driver performs the corresponding action. For example, the seat belt indicator turns off once the driver fastens the seat belt. The third category comprises fault indicators, which are the most critical. These include the generator fault indicator, ABS fault indicator, transmission fault indicator, etc. Generally, these fault indicators rarely light up during normal operation or may briefly illuminate when starting the engine before turning off. If a fault indicator remains lit and is accompanied by a warning sound, it indicates that the vehicle has developed a fault or abnormality.
Having driven for over a decade, I'm quite familiar with dashboard symbols. Back when I was learning to drive, seeing a bunch of warning lights would make me nervous. Now I understand: an oil can light means the oil level is low and needs immediate topping up, otherwise the engine could be damaged; a battery light indicates an issue with the charging system, possibly a faulty alternator or battery; the red parking brake light sometimes gets left on, and the car will beep when you start driving; an airbag light is dangerous - if not addressed, the airbags might not deploy in an accident. Yellow lights like the check engine light might indicate minor issues that become problematic if ignored, but red lights mean you should stop immediately - don't take chances. I advise beginners to make it a habit to scan the dashboard before starting the car and frequently consult the symbol diagrams in the owner's manual, as designs vary significantly between brands - don't take them lightly.
As a new driver, the dashboard lights have me all confused. Last time, the engine light suddenly came on, and I got so nervous my palms were sweating. I pulled over and called for repairs, only to find out it was just the oil cap not tightened properly. Now I've memorized some basics: the ABS light means anti-lock braking system failure - slow down on wet roads; the thermometer light indicates engine overheating - shut off immediately to cool down; the seatbelt reminder light keeps beeping if you forget to buckle up. Others like the tire pressure light signal serious air leakage risks, while the door ajar light is common - just close it properly again. When encountering unfamiliar lights, don't drive long distances. It's best to take a photo with your phone to search the meaning or ask experienced drivers. Safety first - don't be as reckless as I was.
Safety is my top priority when driving, and dashboard symbols are often fatal warnings that should not be ignored. If the brake system light is on, the brakes may fail—stop immediately. The oil pressure light indicates insufficient lubrication, which can damage the engine. A faulty airbag light must be repaired right away. Red lights are emergency-level alerts that require immediate attention, while yellow lights, such as emissions system warnings, should not be ignored for long. During regular maintenance, have someone check all indicator lights to ensure they are functioning properly. A quick scan before starting the car to confirm no abnormal lights are on can prevent accidents, especially on highways—never risk continuing to drive.
