What does it mean when the Corolla's off yellow light is on?

[Noah]

Corolla's off yellow light is a traction control system deactivation indicator. Function of the vehicle's traction control system: The vehicle's traction control system, also known as the traction control system, prevents the driving wheels from slipping during acceleration and starting, maintaining the stability of the vehicle's direction. It prevents the driving wheels from slipping during acceleration, especially on special road surfaces with low friction such as rain, snow, hail, or icy roads. When the vehicle accelerates, it controls the slip ratio within a certain range to prevent rapid slipping of the driving wheels. When the driving wheels slip, it compares the speed of each wheel, automatically reduces the throttle intake, lowers the engine speed, thereby reducing power output, and applies braking to the slipping driving wheels. Usage of the Corolla's traction control switch: The ESP switch is located in front of the gear lever key area. By default, the ESP function is enabled. Press this button to deactivate the function. The ESP function is intelligently controlled by the vehicle's computer and does not require manual control by the driver. It mainly maintains the vehicle's stability under extreme conditions. In situations where side slip or tail swing may occur, it can reduce the engine's output torque. It uses independent control of certain wheels to prevent danger and improve ride comfort. Therefore, do not deactivate this function during normal driving.
