Does OFF mean on or off?

[GiaLee]

OFF means off. ON and OFF on machine switches represent the power-on and power-off states, respectively. They are not abbreviations but the full English words, where ON means on and OFF means off. Of course, some car switches may also be labeled with terms like headlight switches. Below is an introduction about OFF: 1. The OFF light in a car mainly refers to ESP-OFF. ESP stands for Electronic Stability Program, which is an active safety device designed to prevent the vehicle from skidding or losing control. If the ESP-OFF light comes on in your car, it means the vehicle's stability control system is either turned off or malfunctioning. Blue and green indicator lights on the dashboard indicate that the corresponding system is on or functioning normally, while yellow and red indicator lights indicate that the system is off or faulty. 2. If you accidentally press the ESP-OFF button in your car, simply press it again briefly to reactivate ESP. If the ESP-OFF light comes on due to a system malfunction, you should promptly take the car to a 4S shop for inspection. There are many reasons why the warning light may come on, such as wiring faults, sensor damage, incorrect signals from the electronic control unit, or a low battery.
