What does 'set' mean on a Volkswagen Polo?

[LeIsabel]

On a Volkswagen Polo, 'set' refers to the cruise control system. When the cruise control button is pressed, the car will maintain that speed. The function is immediately canceled when the brake pedal is pressed. The role of cruise control is: Cruise control means maintaining the speed automatically without pressing the accelerator pedal, allowing the vehicle to travel at a fixed speed. The principle of cruise control is: The cruise control component reads the pulse signal from the speed sensor and compares it with the set speed, then issues commands to mechanically adjust the throttle opening through the servo, increasing or decreasing it to keep the vehicle at the set speed.
