The 'set' on a car dashboard is a cruise speed control indicator. Here is a detailed introduction about car dashboards: Overview: A car dashboard is a device that reflects the working conditions of various vehicle systems. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights. Others: Currently, beneath the dashboard cover, there are various indicator or warning lights, such as the coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, Anti-lock Braking System (ABS) indicator, traction control indicator, and airbag (SRS) warning light, among others.

I've been driving for over twenty years and have seen the 'set' light on the dashboard many times, which usually indicates that the cruise control system has set a speed. When you're driving on the highway, pressing the 'set' button on the steering wheel will automatically lock the current speed, allowing the car to continue moving forward, making long-distance driving easier by eliminating the need to constantly press the accelerator. If the 'set' light is illuminated on the dashboard, it means the cruise control function is active. However, sometimes it might light up for no apparent reason, possibly due to a system glitch or a stuck button, in which case you should visit a repair shop as soon as possible to check the circuit or sensors. Cruise control is quite useful, but avoid using it in rainy, snowy, or congested conditions to prevent accidents. Remember, safety always comes first. Regular maintenance of the electronic systems can prevent minor issues from turning into major failures.

I just got my driver's license and was also curious about what 'set' means. Later, I found out it's mostly related to cruise control. For example, when I drive my sedan, I press the cruise control switch and then hit the 'set' button to let the car maintain its speed automatically, which is great for long highway trips—no need to constantly control the throttle. But beginners should note that after activating 'set,' you must always be ready to hit the brakes or press the cancel button in case of emergencies. If the light comes on without any operation, it might indicate an internal circuit issue, like a faulty button contact or a blown fuse, and you should get it diagnosed by a professional. This feature is quite convenient, but don’t over-rely on it for driving—manual control is still the core, and safety comes first. Make sure to familiarize yourself with the car manual before hitting the road.

I'm a car enthusiast who loves studying various features. In most vehicles, 'set' indicates that the cruise control has been activated at a specific speed. Pressing the button records the current speed and maintains it automatically, making the driving experience smoother, especially on long trips where it's quite convenient. Modern cars might also have time or distance setting menus, but in most cases, when the 'set' light is on, it means cruise control is active. Regularly checking electronic components, such as wiring harnesses or switches, can prevent false light issues. I believe this system enhances driving pleasure and efficiency, but it's essential to use it according to actual road conditions to ensure it functions properly.
