What does CANCEL/RES mean in a car?
2 Answers
CANCEL is to deactivate the cruise control, while RES is used to resume the previously set speed after pressing the accelerator or brake during cruise control. Below are related introductions: 1. About cruise control: The cruise control system (CRUISE-CONTROL-SYSTEM), abbreviated as CCS, is also known as speed control device, speed control system, or autonomous driving system. 2. The function of cruise control: After the driver sets the desired speed and engages the switch, the vehicle will automatically maintain that speed without the need to press the accelerator pedal, allowing the car to travel at a constant speed. Using this device, when driving on highways for long periods, the driver no longer needs to control the accelerator pedal, reducing fatigue and unnecessary speed changes, which can save fuel.
When driving on the highway, I often use the 'cancelres' button, which actually refers to the cancel/resume function of the cruise control system—you might have misspelled it. Pressing it immediately cancels the currently set cruising speed, and pressing it again when needed restores the original speed. This design makes long-distance driving much easier, especially when encountering traffic congestion or needing temporary speed adjustments—just one press disengages the automatic control. I've driven different car models, and the button is usually located on the steering wheel, making it super intuitive to operate—but beginners should be careful not to cancel it randomly at highway entrances or curves to avoid distractions. If the button isn't working, it might be due to poor contact or circuit issues; older cars are prone to dust buildup causing this. I'd recommend checking the car's fuses every six months—don’t wait until nighttime highway driving becomes dangerous. Safety first! Modern cars also integrate smart systems, like adaptive cruise control, which are even more reliable.
