What does the 'cancel' button on the steering wheel mean?

The 'cancel' button means to cancel, and this button usually only appears on vehicles equipped with cruise control functionality. It is used to deactivate the cruise control. After activating cruise control on the highway, you can cancel it by pressing the 'cancel' button or stepping on the brake pedal. Next to the 'cancel' button, there is usually a 'set' button. Pressing this button will maintain the current speed for cruising, allowing the vehicle to maintain a constant speed without the driver needing to press the accelerator pedal. This feature can effectively reduce driver fatigue during long-distance high-speed driving. The role of cruise control: Cruise control is used to maintain a set speed for the vehicle. Once the car is set to cruise mode, the engine's fuel supply is controlled by the computer. The computer continuously adjusts the fuel supply based on road conditions and the vehicle's driving resistance to keep the car at the preset speed without requiring throttle input from the driver. This not only reduces fatigue but also minimizes unnecessary speed fluctuations, thereby improving fuel efficiency. Related cruise control buttons: The 'cancel' button deactivates cruise control, 'res' resumes cruise control, and 'main' turns off cruise control completely. Before activating cruise control, the driver should set the desired speed using the 'set' button. The plus and minus buttons on the right side of the steering wheel can be used to adjust the cruise control speed—press the plus to increase speed and the minus to decrease it.
I'm a new driver and quite curious about the 'cancel' button on the steering wheel. It's mainly used with the cruise control system. For example, when you set a constant speed for highway driving, pressing this button immediately cancels the setting, returning the car to normal speed controlled by your foot on the accelerator. This design is very thoughtful—if there's sudden traffic or an obstacle ahead, a light touch safely exits cruise control, preventing a high-speed collision. Some car models' cancel buttons even have a resume function: after canceling, pressing it again shortly after can restore the previous speed. While cruise control reduces fatigue on long trips, the cancel button acts as a safety net, reminding me to always check the manual before using cruise control to ensure proper operation.
