What does it mean when the small car icon lights up on the dashboard?

The car icon is the indicator light for the vehicle's anti-theft system. Below are the possible reasons why the small car icon lights up on the dashboard: 1. Reasons for the small car icon lighting up: If the small car icon stays lit, it may indicate that the vehicle stability system is turned off. If it flashes while driving, it means the vehicle stability system is active. If the icon shows a car with an open door, it means a door is not properly closed. 2. Dashboard indicator lights: Modern vehicle dashboards have various indicator or warning lights beneath the panel, such as coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, anti-lock braking system (ABS) indicator, traction control indicator, and airbag (SRS) warning light, among others.
Last time when I was driving the old Lavida, the dashboard also popped up a small car icon. The technician used a computer to diagnose and found it was a glitch in the smart key system. Nowadays, the dashboard lights in new cars are quite intelligent. A small car with a triangle exclamation mark usually indicates an electronic stability system fault, such as a wheel sensor covered in mud; a small car with a key means it can't detect the car key, possibly due to a dead key battery or electronic interference; if it's a small car plus an engine icon, it's most likely an engine anomaly. My experience is to first check if the fuel tank cap is tightened, as a loose cap causing air leakage can also trigger the alarm. The safest approach is to connect to a mobile app to check real-time fault codes, avoiding unnecessary trips to the repair shop.
Don't panic when the dashboard car icon lights up. In my ten years as a mechanic, I've seen too many false alarms. First check the light color: yellow means you can keep driving, red requires immediate stopping. In modern models, this car symbol often relates to the powertrain - 80% of cases are just abnormal emission monitoring, frequently triggered by low-quality fuel from gas stations. A car icon with wavy lines indicates traction control activation, common during wheel slip in rain or snow. I remember an Audi customer whose warning light turned out to be just throttle body carbon buildup - revving the engine in neutral cleared it. Of course, coolant leaks or faulty oxygen sensors can also trigger the light. I recommend using an OBD scanner for diagnosis first.
