What are the warning lights on the car dashboard?

Car dashboard warning lights include the engine oil warning light, engine fault warning light, coolant temperature warning light, brake system warning light, tire pressure warning light, etc. When a warning light illuminates, it indicates a corresponding issue. Car dashboard warning lights: Engine oil warning light; The oil light is a safety alarm device for the engine lubrication system. If the oil light flashes while driving, the engine must be turned off immediately for inspection. Continuing to drive may cause engine damage and compromise driving safety. Engine fault warning light; The engine fault signal is issued by the engine control unit (ECU), which manages all electronic components of the engine, such as the electronic throttle, fuel injectors, alternator, fuel pump, etc., covering systems like intake, exhaust, fuel, ignition, and timing. Coolant temperature warning light; When this light turns on, it usually indicates overheating. If the coolant temperature reaches 100°C while driving, the temperature warning light will illuminate, commonly referred to as "boiling over." When this happens, pull over safely but avoid shutting off the engine immediately, as overheating can cause engine components to expand and lead to damage upon shutdown. Brake system warning light; This light illuminates when the parking brake is engaged. If it remains lit after releasing the parking brake, it signals a brake system issue, often due to low brake fluid levels or worn brake pads. Continued driving under these conditions risks vehicle integrity and driver safety. Tire pressure warning light; If this light activates, determine whether the pressure is too high or too low. Excessive pressure increases the risk of a blowout, so reduce tire pressure accordingly. Insufficient pressure harms tires and increases fuel consumption—reinflate promptly and inspect for punctures causing leaks. The battery indicator displays the status of the car battery, typically in red or yellow. It lights up during ignition self-check and should turn off after starting. If it stays on, the battery requires inspection or replacement. Power steering fault light; Illumination while driving indicates a malfunction in the power steering system, possibly resulting in reduced or lost assistance. Steering effort will significantly increase, and professional diagnosis is required as this issue cannot be self-repaired. Electronic Stability Control (ESC) indicator; This yellow light shows the ESC system's operational status. Normally, it remains off unless there's a fault or the system is actively engaged.
