What does the cancel button in the car mean?

The cancel button in the car is the function key to cancel the cruise control, set is to set the current speed as the cruise speed, and resume is to restore the original cruise speed. The cruise control system is also called cruise control device, speed control system, autopilot system, etc. The function of the cruise control system is: After switching to the speed required by the driver, the vehicle speed is automatically maintained without stepping on the accelerator pedal, so that the vehicle can travel at a fixed speed. After using the cruise control setting, when driving on the highway for a long time, the driver does not need to control the accelerator pedal, which reduces fatigue and reduces unnecessary speed changes, saving fuel.
When I drive myself, the CANCEL button is the temporary deactivation key for the cruise control system. Imagine cruising on the highway at 120km/h when suddenly a slower car appears ahead or road conditions worsen—pressing the CANCEL button instantly cancels the current setting, allowing the car to decelerate to manual control. Unlike the full cruise-off button that requires resetting, it retains the previous speed memory, so pressing RESUME lets you instantly revert to the original speed. This design makes long-distance driving incredibly convenient by reducing repetitive adjustments, especially when encountering sudden traffic changes like roadwork or accidents, enabling quick and composed responses. Note that not all cars function identically—some advanced models like Teslas use the CANCEL button in adaptive cruise control to disengage automatic following, avoiding collision risks. Mastering this button enhances both safety and driving comfort.
