Methods to turn off the car maintenance warning light: It is necessary to troubleshoot the issue related to the warning light and use a diagnostic scanner to reset the code, after which the warning light will turn off. The maintenance warning light, also known as the fault indicator on the car dashboard, alerts the driver when there is an issue. When this light comes on, the owner should either address the problem based on the specific warning or visit a 4S shop for professional repair to ensure future driving safety. Reasons for the engine warning light to illuminate: 1. When sensors are damaged, have poor connections, or signal interruptions occur, the car's ECU cannot accurately obtain engine data, triggering the engine warning light. 2. If the owner fails to perform regular maintenance or has poor driving habits, it increases the engine's operational burden, eventually causing the engine light to illuminate. 3. If the owner does not add engine oil as required, prolonged use can lead to engine wear, resulting in the fault light turning on.

Why Can't Air Be Pumped into the Tire?

Generally, if you can't pump air into the tire after replacement, it is mostly due to the excessive gap between the tire and the rim, causing the air leakage speed to exceed the inflation speed. Seal the Rim: Lift the tire and repeatedly strike the ground to ensure the tire bead fits tightly against the rim. Use a Larger Inflation Device: Use an inflation device with a higher air output. When the inflation speed exceeds the leakage speed, the tire bead will gradually close against the rim under the pressure. Replace Damaged Tires Promptly: As the terminal component that bears the vehicle's weight and contacts the ground, while also providing the necessary friction for driving, tires operate in extremely harsh conditions. They not only endure extreme temperatures but also face erosion and wear from rain, sand, and stones. In such demanding environments, even the best tires will eventually age and wear out. Once a tire is severely aged or damaged, it should be promptly repaired or replaced.
