What does 'off' on the car door mean?

[MacCarmen]

Taking the Audi A6L as an example, the 'off' on the car door is the button to turn off the vehicle stability control system. This system is enabled by default, and pressing and holding this button will turn it off. To prevent theft of the Audi A6L, the manufacturer installs numerous anti-theft systems. Once the owner locks the doors and leaves the vehicle, this system automatically activates. If someone attempts to forcibly open the door, it will immediately trigger an alarm to attract attention. More details are as follows: 1. In the Audi A6L, 'OFF' means off, and 'ON' means on. The 'off' light on the car mainly refers to ESP-OFF, where ESP stands for the Electronic Stability Program, an active safety feature designed to prevent the vehicle from skidding or losing control. 2. If the ESP-OFF light on the car's dashboard illuminates, it indicates that the vehicle's stability control system is either turned off or malfunctioning. When the speed difference between the left and right wheels exceeds the threshold set by the computer, the system will interpret this as the vehicle skidding or losing control. It will then take appropriate action, such as applying brakes to individual wheels and reducing engine torque, to prevent skidding or loss of control.
