What does it mean when a wrench light comes on in the car?

When a wrench light comes on in the car, it indicates that the vehicle requires maintenance. The light will turn off after the maintenance is completed following the proper procedures. Maintenance items include engine oil, three filters (air, oil, and fuel), spark plugs, transmission fluid, coolant, brake fluid, brake pads, and the battery. The replacement cycle for the battery is generally 40,000 kilometers, but its lifespan can be appropriately extended based on actual usage. The benefits of car maintenance include: 1. Ensuring the vehicle remains in excellent performance condition; 2. Improving the vehicle's efficiency and reducing the wear of its parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Keeping the vehicle's appearance clean and preventing damage.
I also panicked when I first saw the wrench warning light on my car. Actually, it's just the car telling you it's time for maintenance. The onboard computer tracks engine mileage to remind you of the service interval—my Volkswagen always lights up right at 5,000 km. You should immediately check the maintenance manual to confirm which engine oil and filter need replacement. The dealership can reset the indicator light using their specialized computer. Never ignore it and keep driving—a friend of mine delayed maintenance for over 1,000 km and ended up with engine failure, costing tens of thousands in major repairs. When you see this light on the road, don't panic; just drive carefully to the repair shop. It's also a good opportunity to check routine items like brake pad thickness.
