What does the Audi SET button mean?

[StJonathan]

set button refers to the use of deceleration after setting the cruise control or temporarily canceling the cruise control. The following is a related introduction: 1. Function: According to the speed required by the owner, the vehicle can automatically maintain the speed without stepping on the accelerator pedal, so that the vehicle can drive at a fixed speed. When the cruise control function is turned on, the speed can be greater than or equal to the lower speed of the cruise control by stepping on the accelerator. After confirming the start of the cruise control function, the engine fuel will be automatically supplied to meet the current speed power driving demand. 2. Working principle: Simply put, the cruise control component reads the pulse signal sent by the speed sensor and compares it with the set speed, so as to issue instructions to mechanically adjust the throttle opening to increase or decrease through the servo, so that the vehicle always maintains the set speed.
