What does the trip button in a car mean?

[McAdeline]

trip stands for the subtotal mileage, and its meaning is quite obvious—it measures the distance traveled by the user for each trip. Here is some relevant information: 1. The data on the left side of the trip button represents the total mileage of the car. Using the trip button to calculate fuel consumption is simple: just divide the distance traveled by the amount of fuel consumed (e.g., how many kilometers can be driven with 100 liters of fuel). 2. Pressing the trip button once will reset the current driving mileage, and it will record the driving distance after the next start. For example, if you want to know the distance from home to the office, press the trip button before starting the car. After starting, it will automatically record the driving distance (note that the minimum unit for trip is 0.1 kilometers, while the minimum unit for total mileage is 1 kilometer). The mileage displayed when you park at the office is the distance from home to the office. 3. The car odometer includes two LCD digital display windows connected to the same signal source, which respectively accumulate the current trip and the total mileage. The current trip usually has four digits for short-term counting and can be reset; the total mileage has six digits and cannot be reset. The mileage data accumulated by the electronic odometer is stored in non-volatile memory, so the data can be preserved even when there is no power.
