A yellow warning light indicates a serious problem with the car that requires immediate repair at a 4S shop or repair facility. A red warning light indicates a severe fault in the alerted area, necessitating immediate repair. In some cases, towing may be required for repairs, depending on the specific fault indicated by the warning light. Generally, the illumination of a warning light is a relatively common issue and not particularly severe. After the warning light comes on, the car can still be driven, but the system becomes non-functional, causing the wheels to lock during emergency braking. Therefore, it is important to drive cautiously after the light comes on and avoid sudden braking. Once the wheels lock, the driver loses control of the steering, and the car may slide forward or to one side, posing a danger. However, in actual driving, emergency braking situations are rare, so driving slowly on icy or snowy roads is essential. On such surfaces, even normal braking can often cause wheel lock-up. Car owners in northern regions should be especially cautious during winter; if the warning light comes on, prompt repairs and careful driving are advised. The ABC warning light indicates a fault in the Automatic Stability and Traction Control System. Indicators can be categorized into three types: status indicators, warning lights, and fault lights. The dashboard uses green, yellow, and red colors to indicate different levels of danger: red for critical alerts, yellow for fault indications, and green for status indicators. Common dashboard indicators include the engine fault light, oil pressure fault light, ABS fault light, anti-skid fault light, battery fault light, steering gear fault light, and brake pad wear warning light. Here is an introduction to the ABC warning light: ABC stands for Active Body Control, an advanced active suspension system. The Body Stability Control System, developed by Toyota, is an active safety feature that significantly enhances vehicle handling safety and driving convenience.
