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

The 'set' button on the steering wheel is related to the cruise control function. On the steering wheel, there are buttons such as 'res'+', 'set'-', the activation (cruise) button, the cancellation (cancel) button, or the ON/OFF switch for control. Function of the 'set' button: The 'set'-' button is used to set the current cruise control speed or to decrease the set speed during cruise control operation by pressing the 'set'-' button. Function of the 'res' button: The 'res'+' button is used to resume the preset cruise control speed or to increase the set speed during cruise control operation by pressing the 'res'+' button.
The Set button on the steering wheel is my great helper during long-distance drives, mainly used to set the cruise control speed. When driving on the highway, pressing Set locks the current speed, freeing my right foot from constantly pressing the accelerator, making the drive much more relaxed. It usually works alongside the acceleration and deceleration buttons for easy speed adjustments. Activating cruise control requires another switch, so don’t rush and press the wrong one. Once, I accidentally pressed it in traffic, but the speed didn’t change, and thankfully, I braked in time without any issues. This feature is especially fuel-efficient and reduces fatigue on smooth roads, while also lowering noise for a quieter ride. Maintenance is simple—the button is sturdy and durable, but dust buildup can cause poor contact, so regular cleaning is enough. Modern new cars might integrate adaptive systems using radar to adjust distance, but the basic Set operation remains just as reliable. I never use it in rain or on curves—safety first. I recommend beginners practice in open areas to get comfortable without distractions.
In my view, the Set button on the steering wheel is essentially a cruise control speed setting key, which I love using most when enjoying a drive to maintain constant speed. Pressing Set allows the system to capture and maintain the set speed, saving foot fatigue. It comes with plus and minus buttons for slight speed adjustments with a gentle press—smart and precise. Modern cars often feature adaptive functions that automatically adjust spacing, but the standard Set remains the core. I frequently test its performance under different highway conditions, as constant speed truly saves fuel, reduces emissions, and benefits engine health. The risk of misuse is minimal—just press the cancel button or brake to deactivate, offering flexibility and peace of mind. Avoid reckless use in urban areas, as traffic lights can lead to awkward situations. The button rarely malfunctions, but if responsiveness lags, check the wiring or fuse. Overall, the design is simple yet efficient, seamlessly integrating with the vehicle's electronic systems—a must-try feature for tech enthusiasts.
Safety comes first when driving on the road, so only activate cruise control by pressing Set at appropriate times. I insist on using it only on open highways: first activate the cruise system, press Set to lock the speed, and use the +/- buttons to adjust the speed. This maintains a steady speed, avoids sudden acceleration, and reduces the risk of accidents. However, stay vigilant—manual control is more stable on curves or steep slopes. If it malfunctions, check for blown fuses or loose cables, and don’t ignore minor issues. Disable it in rainy conditions with low visibility to ensure focused driving. It makes the journey more comfortable, but the core principle is safety awareness. The simple buttons embody intelligent control principles—just practice until you’re proficient. I recommend every driver review the steps regularly to ensure flawless operation.
