What is the function of the set button on the steering wheel?

The set button on the steering wheel is the speed setting button for the car's cruise control system. SET has two functions: one is to reduce speed after setting the cruise control, and the other is to set the current speed as the cruise speed after temporarily canceling the cruise control. The following is an introduction to the cruise control system: Currently, most cruise control systems mainly have the following buttons: the on/off key (ON/OFF), the cancel key (CANCEL), the set current speed (SET), the resume set speed (RES), and the acceleration (+) usually combined with the RES key, while the deceleration (-) is combined with the SET key.
I often use the SET button on the steering wheel while driving, which is a key component of the cruise control system. Basically, when you reach your desired speed, say 100 km/h on the highway, activating cruise control and pressing the SET button locks the current speed. The car then automatically maintains this speed without needing to press the accelerator, making driving much easier. It's especially useful for long-distance driving, significantly reducing fatigue. However, it's important to only use it on dry, clear roads—avoid activating it during rain or heavy traffic as it can be dangerous. Also, always check the dashboard after adjusting the speed to confirm the setting was successful; otherwise, an invalid setting wastes the function. Remember, this button is usually paired with +/- buttons for easy speed adjustments. In short, making good use of the SET button makes driving much more comfortable.
I've been driving for several years, and the SET button is a real lazy tool for me. Its main function is to set a fixed speed. When driving on the highway, pressing the SET button allows the car to run on its own, giving my hands a break from constantly monitoring the throttle. The obvious benefit is fuel savings, as maintaining a steady speed leads to more consistent fuel consumption. However, it's best used on flat roads—steep slopes or sharp turns make it unreliable. Personally, I prefer to first activate the system with the cruise control main switch, find a suitable speed, and then press the SET button to lock it in. If I need to overtake temporarily, canceling the setting is simple—just tap the brake to revert to normal driving. New car owners might not be familiar with this feature, so I recommend reading the manual or experimenting gradually, especially avoiding fiddling with this button in chaotic situations. Safety first—this design is truly thoughtful, elevating the driving experience.
