What is the SET button on the car door?

The SET button on a car stands for speed regulation switch, which is the speed adjustment indicator for cruise control. Below are the methods to activate and use cruise control: 1. Activating cruise control: First, press the CRUISE button to activate the cruise module. When the dashboard displays CRUISE, the vehicle must reach a speed of 40 km/h or above to enable cruise control. Once at 40 km/h, press the SET button to activate cruise control. 2. Speed adjustment: Speed can be increased or decreased using the "+" and "-" buttons. Pushing the lever upward increases the speed, while pushing it downward decreases the speed. Holding the lever in position will rapidly increase or decrease the speed. 3. Canceling cruise control: Pressing the accelerator or pushing the lever downward will temporarily cancel the function. Releasing the accelerator or pushing the lever inward will automatically restore the function. The CANCEL button is used to deactivate cruise control.
I frequently use the Set button on my car door, which is the control key for the seat memory function. After adjusting the seat height and front/rear position, press and hold the Set button, then press a nearby number key like 1 or 2 to save the current settings. The next time you drive, simply press the number key lightly, and the seat will automatically return to the stored position. This is especially convenient for households where multiple people share the same car. My SUV also memorizes the rearview mirror and steering wheel positions, making each drive more comfortable. The operation is quite simple—there's a beep when holding Set to indicate recording. This feature is common in high-end models but is also available in some regular cars. Remember to adjust your seating position properly before pressing the button to ensure accurate memory. Overall, it eliminates the hassle of manual adjustments and improves driving efficiency.
I've studied the Set button on the door, which actually serves as the trigger switch for the seat memory system. After adjusting your seat, hold down Set and select a memory key, and the system will record the current position data of the seat motor. Internally, a microprocessor stores these settings, and the next time you recall them, the motor automatically moves to the preset position. Some models even extend this feature to memorize rearview mirror angles, ensuring a consistent panoramic view. I've used this feature in my daily driving, and its main advantage is reducing tedious operations, especially during long trips or when family members take turns driving, allowing for quick switching. Don't worry about complexity when using it—the buttons are usually located on the door panel and designed to be intuitive. Of course, if the battery is disconnected, the memory will be lost and require resetting, but this rarely happens.
