What does the CLR button mean?

[SanRyder]

In a car, the CLR button is a function key used to select features or confirm certain information. Below are the relevant details about CLR: 1. Function: When the trip computer displays items like the trip mileage, average speed, or average fuel consumption, pressing and holding the SET/CLR button at the top of the control lever will emit a beep, after which the trip mileage and average speed will reset, and the average fuel consumption will revert to the initial value. 2. Usage: Press the MENU button to enter the trip computer display settings, where three lines of code will appear. The top line will show one of the numbers 1, 2, or 3. Press the CLR button to enter the format selection interface, where two lines of code will appear. The bottom line corresponds to the number from the first line of the previous interface. Rotate the knob to select one of the numbers 1, 2, or 3, then press CLR again to save. Exit back to the three-line code interface and press MENU to return to the trip computer display interface.
