The most serious warning lights on a car's dashboard are the red emergency warning lights, especially the oil pressure warning light (oil can icon), the brake system warning light (exclamation mark inside a circle), and the high engine temperature warning light (thermometer inserted into wavy lines). The illumination of the oil pressure warning light indicates a failure in the engine's lubrication system; continuing to drive may cause severe engine damage, so the engine should be turned off immediately to check the oil level or contact maintenance. The high engine temperature warning light indicates that the engine's cooling system has failed; high temperatures may cause cylinder block deformation or cylinder explosion, so the vehicle should be stopped and idled to cool down, and the coolant should be checked. These red warning lights all require immediate attention; otherwise, they will directly threaten driving safety or result in high repair costs. Although yellow warning lights such as the check engine light or ABS light need to be inspected and repaired as soon as possible, short-distance low-speed driving is allowed. It is recommended that car owners regularly check the status of fluids, tyres, and sensors, and read the vehicle manual thoroughly to accurately identify various warning lights.
