What does the small stick on the Mazda CX4 dashboard mean?

[StAngelo]

Introduction to the meaning of the small stick on the Mazda CX4 dashboard: 1. Displays average fuel consumption. Press the small black stick once, and it will show the average fuel consumption, measured in L/100km. However, this data is for reference only. For example, the Ford Escort manual comfort model displays 6.3L/100km here, while the actual fuel consumption is around 7.5L. 2. Displays instantaneous fuel consumption. Instantaneous fuel consumption equals the fuel consumption in an instant divided by the distance traveled by the vehicle with that fuel in that instant. Since an infinitely small time cannot be measured, it is usually calculated in 2-second intervals, which may explain why many cars show an instantaneous fuel consumption of 99.9L/100km when idling at a red light. 3. Displays remaining range. Simply put, the working condition specifies the type of road, speed, and duration (distance) of travel.
