What is the purpose of setclr?

[CharlotteLee]

SET/CLR is a function button used to select a feature or confirm a piece of information. When the trip computer displays the trip mileage, average speed, or average fuel consumption, pressing and holding the SET/CLR button at the top of the control lever will trigger a beep sound, after which the trip mileage and average speed will be reset, and the average fuel consumption will revert to the initial value. Additional details are as follows: 1. Press the MENU button to enter the trip computer display settings: Three lines of code will appear, with the top line displaying one of the numbers 1, 2, or 3 (the number represents the display format). Press the SET/CLR button to enter the format selection interface, where two lines of code will appear, with the bottom line corresponding to the first line of numbers from the previous interface. 2. Rotate the knob (up/down arrows): Select one of the numbers 1, 2, or 3 and press SET/CLR to save and exit, returning to the three-line code interface. Press MENU to return to the trip computer display interface. 3. IV Technology: In the early 1990s, the concept of Intelligent Public Transport Systems (ITS) was introduced abroad, with Intelligent Vehicles (IV) being a crucial component of Intelligent Transportation Systems. IV technology encompasses multiple technologies such as computers, mobile communications, and automatic control, enhancing vehicle comfort, entertainment, safety, and convenience. PC platform-based automotive informatization serves as the foundation and prerequisite for achieving IV technology.
