What does a half-circle with an X warning light mean?

It is likely the power steering system malfunction warning light. It is recommended to check if there are any issues with the power steering system. Car warning lights, as the name suggests, are indicators that display vehicle malfunctions. These lights are like health signals for your car and should be given some attention. Ignoring them may lead to more serious problems. Here are eleven important warning lights that, when illuminated, suggest you should stop and inspect your vehicle to avoid more severe hazards: 1. Oil Pressure Warning Light: Indicates that the engine oil level or pressure is below the standard value. 2. Coolant Temperature Warning Light: Indicates that the engine temperature is too high or the coolant level is too low. 3. Door/Trunk Open Indicator: Indicates that a door, hood, or trunk is not properly closed, which could lead to it opening unexpectedly while driving. 4. Power Steering System Warning Light: Indicates that the power steering may be weakened or completely lost, or could suddenly fail while driving. 5. Battery Charge Warning Light: If illuminated while driving, it indicates a malfunction in the vehicle's charging system. 6. Brake System Warning Light: Indicates a fault in the braking system or improper operation. 7. ABS Warning Light: If illuminated while driving, it indicates an abnormality in the ABS electronic control system (ABS will be disabled). 8. Tire Pressure Warning Light: Indicates that the tire pressure in one or more tires is significantly low or uneven. 9. Engine Malfunction Light: Indicates that the engine is not operating normally. 10. Transmission Warning Light: Indicates a fault in the automatic transmission. 11. Washer Fluid Indicator: Primarily shows whether the windshield washer fluid is low. If illuminated, it usually means the fluid level is insufficient and needs to be refilled promptly.
When that half-circle with an X symbol appears on the dashboard, it's usually the tire pressure monitoring system (TPMS) warning light. Having driven for over a decade, I've encountered many similar issues. This light indicates either low tire pressure or a system malfunction, such as a faulty sensor or uneven tire pressure. Insufficient pressure accelerates tire wear, increases blowout risks, and may extend braking distances - especially dangerous during rainy conditions. I recommend immediately pulling over to inspect all tires with a portable pressure gauge, as standard pressure values are typically labeled on the door jamb. If the light persists despite normal pressure readings, it likely indicates sensor contamination or failure. Don't ignore it - visit a repair shop promptly to avoid costlier repairs later. Monthly pressure checks effectively prevent such issues. Remember, tire pressure naturally drops in winter temperatures, requiring extra attention. Safety first - never gamble with seemingly minor warnings.
