What is the SET button in a car?
1 Answers
The SET button in a car is a speed adjustment switch, which serves as the speed regulation indicator for cruise control. When setting the cruise control, the vehicle needs to be accelerated to the desired speed, and then the SET button is pressed to adjust. To use cruise control, first press the ON button to activate the cruise control function. When setting the cruise control speed, press the SET button to configure it. Cruise control has speed limitations, typically requiring the vehicle to be traveling at least 48 km/h. If the brake pedal is pressed during driving, the cruise control will deactivate. To resume cruise control, press the RSM button in the car. To increase the cruise control speed, press the ACCEL button. To decrease the cruise control speed, press the CST button. The cruise control function in a car works by using a speed sensor to transmit signals and compare them with the set speed, ensuring the vehicle maintains the preset speed. The car's computer can then provide the most accurate fuel supply. Using cruise control allows for more complete fuel combustion in the engine, while also reducing fuel consumption.
