It is recommended to set it to 100Hz, 5; 200Hz, 4, as this setting provides the best bass sound. Below are the methods for adjusting and maintaining car audio settings: Sound adjustment entry: After starting the vehicle, the central control screen will display vehicle information. Click the button on the right side of the multifunction keyboard to switch to the audio adjustment mode. Once in the mode, you can adjust the parameters until you achieve your preferred sound. Audio maintenance: To ensure the longevity of the audio system, proper maintenance is essential during regular use. For example, if the car has not been used for an extended period, ensure proper ventilation. In hot weather, also pay attention to ventilation to prevent heat buildup that could damage the audio system. Additionally, be mindful of the volume level during regular use. Avoid keeping the volume too high for prolonged periods to prevent degradation of sound quality and potential damage to the audio system.

Why Does the Average Fuel Consumption Suddenly Increase After Refueling?

After refueling, the car's fuel consumption will show a particularly noticeable increase. The reason is that the initial fuel consumption calculation is basically fuel consumption divided by mileage, combined with speed calculation, and since the distance is almost zero, the fuel consumption will be very high. As speed, road conditions, and mileage increase, the fuel consumption will tend to normalize. The precautions for refueling are as follows: 1. Refuel in advance: Try not to wait until the fuel is completely exhausted before refueling, as this can easily reduce the lubrication effect of the engine and affect its service life. 2. Go to a regular gas station: When refueling, go to a regular gas station to add high-quality fuel, which helps the engine work and can also extend its service life. 3. Do not mix fuels: Different types of fuel should not be mixed, otherwise it may damage the engine, and in severe cases, the engine may be directly scrapped.
