Use the selection and confirmation buttons on the multifunction steering wheel to operate the car's central console. Enter the settings, open general management, and you will see the unit options. Click on mph, and the system will automatically switch to kph, which means changing the unit to kilometers per hour. Here are some related introductions: 1. Generally, European and American cars prefer to use the mph unit, which stands for miles per hour in English, meaning miles per kilometer in Chinese. Most cars in the world, like Chinese cars, prefer to use the universal unit kph, which stands for kilometers per hour. 2. This unit management is set by the onboard computer. The onboard computer is a high-tech electronic product that can also read car data through advanced technology, monitor car exhaust emissions in real-time during the engine's working state, and issue an alert immediately if the emissions exceed the standard. 3. When the car's system fails, it will notify the car's onboard computer, which then stores the fault information in the control module. The fault code can be read through a certain procedure to remind the maintenance personnel of the nature and location of the fault. Therefore, the onboard computer can display all the information stored in the car's ECU, making it convenient to query when the car fails, and it can also be used to control the engine's fuel injection volume and the proportion of the mixture.
