What does it mean when a wrench symbol appears on the car display?
2 Answers
It is normal for a wrench symbol to appear on the car display. This is the maintenance reminder on the dashboard. When the vehicle's mileage or time reaches the set maintenance requirement, the small wrench symbol will appear. After the maintenance is completed, the staff at the 4S dealership will reset the maintenance mileage through the setup program, and the maintenance light (wrench symbol) will be cleared. If maintenance has already been performed but the maintenance light remains on, you can try the following steps to reset and clear it: 1. Turn off the car's ignition switch; 2. Press and hold both black buttons on the dashboard simultaneously; 3. Turn on the ignition so all dashboard lights illuminate; 4. Wait until the wrench light (maintenance light) turns off; 5. Release both buttons after the light goes off; 6. Restart the ignition switch.
I noticed that when the wrench icon appears on the car, it is mostly a reminder signal from the vehicle maintenance system, indicating that it's time for routine maintenance. This could mean the oil change is due, the filter needs cleaning, or the system has detected that the mileage has reached the threshold prompting you to visit the workshop for inspection. In some cases, it might also be a false alarm caused by sensor errors or minor wiring issues, especially common in new cars or when maintenance has been overdue for a long time. I recommend first checking the user manual to confirm the specific meaning, then performing some simple self-checks based on the vehicle model, such as checking if the oil level is normal. If the icon remains lit, don't delay—visit a reliable repair shop or authorized dealership as soon as possible for diagnosis and repair. Ignoring such warnings may lead to increased engine wear or more significant failures, affecting driving safety and vehicle longevity. Developing a habit of regular maintenance can make your car more durable and hassle-free.
