The reason for the wrench icon appearing on the car dashboard is to remind the owner to perform car maintenance. The car maintenance items include: 1. Changing the engine oil and oil filter; 2. Replacing the oil filter element, air filter element, fuel filter element, air conditioning filter element, and transmission oil filter element; 3. Adding windshield washer fluid, antifreeze, and air conditioning refrigerant; 4. Checking whether the drive belt is worn; 5. Cleaning the throttle valve and carbon deposits in the cylinders; 6. Inspecting the chassis for damage; 7. Checking the body and tires. The functions of car maintenance: 1. Ensuring the vehicle's excellent performance condition; 2. Improving driving safety; 3. Reducing engine noise; 4. Extending the vehicle's service life.
I've been driving for several years and know that the wrench icon on the dashboard is a maintenance reminder signal, indicating that it's time for service according to preset mileage or time intervals. This is usually calculated by the car's built-in computer system, such as when the oil change cycle is due or the filter needs cleaning. If not addressed promptly, the engine may experience accelerated wear or even overheat and stall, affecting driving safety. I once ignored it, and my car broke down on the road. The mechanic said it was due to dried-up oil causing parts to burn out, costing me money and trouble. From that lesson, I've made it a habit to go to a 4S店 or reliable repair shop as soon as the icon appears—don't try to save money or time. I usually advise car owners to regularly check their vehicle manuals to understand the maintenance schedule, which can extend the car's lifespan and reduce unexpected risks.
