Car dashboard warning lights may illuminate due to parking sensor failure, excessively worn brake pads, engine oil pressure sensor malfunction, insufficient brake fluid, fuel cutoff system intervention or failure, etc. The identification methods are as follows: A triangle with an exclamation mark in the middle indicates a general fault warning light, which may illuminate under the following circumstances: Overheating of the dry dual-clutch transmission clutch. Fuel cutoff system intervention or malfunction. Parking sensor failure. External light malfunction. Engine oil pressure sensor failure. Traction control system warning or failure. A circle with an exclamation mark in the middle and parentheses around it indicates a brake system warning light, which may illuminate under the following conditions: In some vehicles, it lights up for a few seconds when the ignition is turned on and turns off after the engine starts. It lights up when the handbrake is engaged and turns off when released. It lights up during driving if the brake fluid level is too low. It lights up when there is a brake system malfunction. A horizontal line with an exclamation mark in the middle and parentheses below it indicates a tire pressure monitoring warning light, which lights up when the pressure in one of the vehicle's tires is too low.

The other day on the highway, a yellow engine light suddenly popped up on my dashboard, scaring me into slowing down immediately. Actually, there are tricks to identifying car warning lights: red lights indicate the highest danger level, like the coolant temperature warning or oil pressure light—you must stop immediately when you see these; yellow lights are medium warnings, such as the check engine light or ABS light, allowing short-distance low-speed driving to a repair shop; green and blue lights are usually function indicators. Don’t panic if you can’t recognize the icons—80% of car models have a small button under the steering wheel. Hold it for a few seconds, and the onboard computer display will show the fault code in English. Snap a photo of the dashboard with your phone and send it to the 4S shop’s after-sales guy—they’ll surely explain it. In a real pinch, flip through that dusty vehicle manual in the glove compartment—the last chapter definitely has illustrated explanations. Remember, a yellow light can wait a couple of days, but never push your luck with a red light.

Last time my bestie was in tears when her new car showed a turtle warning light. Actually, recognizing warning lights isn't hard—just remember this rhyme: 'Red means stop, yellow means check.' For red lights like battery or brake system warnings, pull over immediately, cut power, and call for help. The most common yellow light is the engine warning—last time mine came on because the fuel cap wasn't tightened properly. Nowadays many cars are smart enough—just press the menu button on the right side of the steering wheel a few times to see Chinese fault descriptions, and premium models even have voice alerts. My old car isn't that advanced, so I keep a complete warning light chart in my phone for reference. The easiest solution is to buy a ¥20 color manual for your specific model on Taobao, and stick a note with the 4S rescue number inside the fuel cap—these three tricks can handle 90% of emergencies.

Fifteen years of car repair experience summarized in three points for warning light identification. Colors indicate three levels: red requires immediate attention, yellow means inspect as soon as possible, while green/blue are status indicators. Shapes also matter - a water drop means low washer fluid, a wrench indicates maintenance reminder, and parentheses with exclamation mark signal tire pressure abnormality. Older German cars often use hidden menus - simultaneously holding the hazard lights and odometer button enters diagnostic mode. New car owners are advised to install professional scanning apps, using an OBD adapter plugged into the diagnostic port under the steering wheel to translate fault codes into plain language. If the dashboard shows a "little man with sword" icon, don't panic - it's the seatbelt reminder, not a duel challenge.
