What does the reset button on a car mean?

[McLouis]

Reset literally translates to reset. The following is a related introduction about the reset button on a car: 1. Introduction: Its function is basically to reset the information on the car dashboard information center, except for the total mileage. The car reset and trip buttons are basically located on the multifunction steering wheel, and some models will place them on the left side of the driver's seat. The positions are different, but the actual functions are the same. The RESET button has the function of clearing the data when the TRIP button is used to switch to the corresponding data. Implementing this function helps to re-examine whether the mileage status of the vehicle after refueling is complete. 2. Precautions for car use: The load capacity during the break-in period should not exceed 75% of the rated load. It is best for a new car to be loaded below the specified weight or number of people when carrying a load. Overloading will increase the burden on the engine, transmission, drivetrain, suspension system, and other components, accelerate wear, and cause serious damage to the vehicle. Therefore, during the break-in period, try to carry 1~2 people and avoid loading cargo. When selecting lubricating oil, it is important to choose low-viscosity and high-quality lubricating oil, which can provide good lubrication to the friction surfaces and slow down component wear. Correctly adjusting the ignition and fuel supply systems can solve the changes caused by the installation of a speed limiter on the vacuum economizer and improve the fuel economy during the break-in period. The components are still in the break-in period, and excessive load and speed will intensify the impact on the parts.

Last time I accidentally pressed this button on the highway, the total mileage displayed on the dashboard was reset to zero. The reset button has quite different functions depending on its location: the one on the steering wheel usually switches the dashboard display information and resets the trip mileage; the one in the center console area is often used to restore the multimedia system to factory settings; the one on the side of the steering wheel is the most important, used to relearn the tire pressure monitoring after tire repair. Pay special attention to the tire pressure reset operation—you must press and hold it for 3-5 seconds after safely parking, and wait until the dashboard warning light flashes to confirm success. Never operate it by mistake, otherwise the alarm failure may cause you to miss real dangers.

The button's function depends on its location. The reset on the multimedia system acts like a factory reset for phones—holding it for 10 seconds clears radio presets and Bluetooth pairings. Last time I accidentally pressed it, all my saved stations disappeared. The one near the instrument cluster resets maintenance reminders; pressing it after an oil change clears the wrench icon. The tire pressure reset is usually in the glove box—it must be pressed after tire repairs. I recommend checking the manual, as locations vary significantly between models. Some cars hide it in a slot under the steering wheel.

When I first bought the car, I was also confused. The most technical part is the tire pressure monitoring system reset: After tire repair, drive for 20 minutes to let the system record the new tire pressure, then press and hold for 5 seconds with the engine off until you hear the confirmation beep for a successful reset. The button on the steering wheel is for resetting the single-trip fuel consumption statistics, while the one on the right side of the steering wheel is actually the temporary trip meter reset button. For maintenance reset, using a diagnostic computer is more thorough, as manual reset might leave residual error codes.
