What does the wrench symbol on the car mean?
3 Answers
The appearance of a wrench symbol on the car indicates that the maintenance light is on, signaling that the car requires maintenance. The items for car maintenance include: 1. Changing the engine oil, oil filter, air filter, and fuel filter; 2. Inspecting the body and tires; 3. Checking the braking system; 4. Examining the chassis for any damage. The benefits of car maintenance are: 1. Ensuring the vehicle is 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 was also puzzled when I encountered this wrench icon before. Later, the mechanic told me it's the system reminding me that maintenance is due. The car automatically calculates the maintenance time based on the mileage, such as lighting up the warning light at 5,000 or 10,000 kilometers. Some cars even display the remaining maintenance mileage on the dashboard. At this point, it's best to check the maintenance manual to confirm what items need to be done, usually including oil and filter changes, brake pad inspections, and so on. Although it doesn't affect driving, don't delay too long. Last week, my neighbor's Mercedes had severe engine carbon buildup because they ignored this warning light. After maintenance, remember to ask the technician to reset the warning light; otherwise, it will light up again the next time you start the car.
Don't panic when you see the wrench light on the dashboard—it's your car's smart reminder system at work. Just like your phone popping up update notifications, the vehicle detects when maintenance is due via the CAN bus. Having studied dozens of car models, I've noticed Kia and Hyundai use a wrench icon with text showing remaining mileage, while some Chinese brands may employ a flashing wrench for tiered alerts. The most practical approach is to note your current mileage and cross-reference it with the maintenance schedule in your owner's manual. If you've just passed the service interval, first check if the engine oil dipstick appears darkened. Here's a lesser-known fact: Vehicles frequently driven short distances may trigger the light earlier, as the system calculates engine wear levels.
