What does the set button in the car mean?
1 Answers
Car's set button is a speed adjustment switch, which is the cruise speed control indicator. When setting the cruise speed, accelerate the car to the predetermined speed and press the set button (the vehicle speed usually needs to exceed 30 mph). During cruise control operation, pressing the brake will deactivate the system. The cruise control system, also known as speed control device or autonomous driving system, automatically maintains the vehicle speed as set by the driver without requiring accelerator pedal input. This feature reduces driver fatigue, minimizes unnecessary speed variations, and improves fuel efficiency.
