In modern cars, the steering wheel is not just a tool used to control the steering of the vehicle, it also integrates many function buttons to provide a more convenient driving experience. Among them, the RES, SET and CNL buttons are one of the common function buttons, but many old drivers are not clear about their specific purpose. This article will explain what these keys do and help you understand and use them better.
res button.
The RES (resume) button is usually located on the left side or above the steering wheel and is used to restore the last set cruise control speed. Cruise control is a driver assistance system that helps the vehicle automatically maintain a constant speed within a set speed range, reducing fatigue on long drives. When you need to resume the previously set cruise speed, just press the RES button and the system will automatically accelerate to the set speed.
The RES button can also be used to restart the system after pausing cruise control. When you pause cruise control, for example because you need to overtake or stop temporarily, press the RES button again to reactivate cruise control and the car will return to the previously set speed.
set button.
The SET button is a button used to set the cruise control speed. The SET button can be used to set the target speed of the vehicle in the cruising state. When you want the vehicle to maintain a certain speed, after pressing the SET button, the system will lock the current speed as the cruise control speed, and the cruise system will automatically control the acceleration and deceleration to keep the vehicle driving stable.
When setting the cruise control speed, there is generally a process of acceleration and deceleration. When you press the SET button, the vehicle will gradually accelerate to the set speed until the target speed is reached. After that, the cruise system will automatically adjust the throttle position to maintain a constant speed, providing a smoother driving experience.
CNL button.
The CNUL (Cancel) button is usually located on the right side or below the steering wheel and is used to cancel or turn off cruise control. When you need to stop cruise control, just press the CNL button. At this point, the cruise system will be turned off and the car will return to manual driving mode, allowing you to control the accelerator and brakes freely.
The CNL button can also be used to cancel the cruise control speed setting. When you want to cancel the pre-set cruise speed, but still keep the cruise system active, press the CNL button. This way, you can continue to use the cruise system, but you won't be limited to a specific cruise speed.
Conclusion. The RES, SET, and CNL buttons on the steering wheel are among the common function buttons in modern cars. They provide a more convenient and comfortable driving experience. By understanding and using these buttons correctly, you can make better use of your cruise control system, reduce fatigue on long drives, and keep your driving safe. Remember, make sure to use these buttons wisely and strictly follow the rules and regulations of the road while driving.
