What does the reset button in a car mean?

The reset button in a car is used to reset the trip mileage. It allows the odometer to be reset, specifically clearing the segmented mileage. Generally, holding it down for up to 3 seconds will clear the data, representing reset, clear, or restore. When the ignition switch is turned off, average fuel consumption, average speed, etc., are stored and can be zeroed out using the reset button on the stalk. RESET: Restart or reset the system. In smartphones or smart PDA products, there is usually a hidden "RESET" button, which serves the same purpose as the restart button on a computer—it reboots the system when it freezes or crashes. How reset works: When the reset button is pressed, the system is directly powered off. Upon release, power is restored, and the system begins the startup process. In cars, the reset button is typically located on the multifunction steering wheel, though some models place it on the left side of the driver's seat. Regardless of the position, its function remains the same. A multifunction steering wheel features buttons on the sides or bottom for easier operation by the driver, including controls for audio, air conditioning, and hands-free calling.
I've been driving for decades, and the reset button in cars is usually a small button on the dashboard, mainly used to reset the maintenance reminder light. After completing an oil change or regular maintenance, the indicator light on the dashboard will flash, and pressing the reset button once will turn it off. This is because the system automatically reminds you to check when the maintenance interval is reached, and resetting it helps you schedule the next maintenance on time. I recommend referring to the vehicle's user manual to find the specific location and operation method, such as near the steering wheel or on the wiper stalk, where pressing it for a few seconds will suffice. Different car models may vary slightly, and some older cars also use it to reset mileage records or system errors. Timely operation can avoid false alarms and ensure accurate driving safety records.
