What do the two mileage readings on the car dashboard mean?

[McElliot]

There are two mileage readings on the car dashboard: 1. Total mileage of the car: Measured in kilometers and cannot be reset. 2. Measurable mileage: This can be manually reset by pressing and holding the black cylindrical button on the dashboard. The total mileage of the car normally cannot be reset. Below are the differences between the two types of car odometers: 1. Mechanical odometer: The traditional purely mechanical instrument, which uses a flexible shaft connected at one end to the transmission output shaft and at the other end to the odometer. 2. Electronic odometer: Generally, a speed sensor is installed on the transmission output shaft or wheel, and the read speed is converted into vehicle speed and mileage through a calculation formula embedded in the control module.
