What does the CANCEL button in the car mean?

It is the cruise control deactivation switch. The introduction of cruise control function buttons is as follows: 1. ON/OFF button – Cruise control switch: (1) When pressing the ON/OFF button, the CRUISE/MAIN indicator light above the coolant temperature gauge illuminates. The cruise control system activates, ready to receive speed setting operations. (2) Pressing the ON/OFF button again turns off the CRUISE/MAIN indicator light. The cruise control system deactivates. 2. SET/COAST button – Speed setting/deceleration control switch (operational above 30 km/h): (1) While driving, pressing the SET/COAST button sets the current speed, and the CRUISE indicator light above the coolant temperature gauge illuminates. Release the accelerator to maintain the set speed. (2) During cruise control, pressing the SET/COAST button again decreases speed by 1.6 km/h per press. (3) Holding the SET/COAST button during cruise control gradually reduces speed. 3. RES/ACCEL button – Acceleration setting/acceleration control switch (operational above 30 km/h): (1) During cruise control, pressing the RES/ACCEL button increases speed by 1.6 km/h per press. (2) Holding the RES/ACCEL button during cruise control continuously increases speed. (3) During cruise control, pressing the CANCEL button temporarily deactivates cruise control. Pressing the RES/ACCEL button again causes rapid acceleration to the previously set cruise speed. 4. CANCEL button – Cruise control deactivation switch: Pressing the CANCEL button during cruise control temporarily deactivates the system, turning off the CRUISE indicator light above the coolant temperature gauge.
I've been driving for over a decade, and the cancel button in cars is most commonly used in cruise control systems. When you activate cruise control, the car automatically maintains speed on the highway. However, if you need to brake suddenly or change lanes, pressing this button immediately exits cruise mode, returning the car to manual driving control. This operation is smoother than directly hitting the brakes, reducing the risk of sudden deceleration. Some car models' navigation systems also feature a cancel button—for instance, if you take a wrong turn or no longer want to follow the prompts, pressing it cancels the current voice guidance quickly and conveniently. Another common scenario is in automatic climate control, where pressing cancel can pause automatic adjustments, such as when you want to manually adjust the fan speed after setting a temperature. In short, it's not a power-off button but rather a pause key for specific functions; accidentally pressing it isn't a big deal, at most requiring a reset.
As a tech-savvy enthusiast who loves driving new cars, I frequently test the cancel button functions in various vehicles. It's incredibly useful in intelligent cruise control: for instance, when encountering traffic congestion, the system automatically decelerates to follow the car ahead, but if the leading vehicle brakes suddenly or makes an overly sharp turn, pressing cancel immediately allows me to disengage, avoiding rear-end collision risks. It's also commonly found in navigation systems; say during weekend road trips if I take a wrong turn, canceling the prompt makes the system recalculate the route, sparing me from nagging distractions. Typically a small button with clear labeling, it offers crisp tactile feedback when pressed – but remember it differs from the resume button, which reinstates previous settings whereas cancel completely pauses the function. In daily driving, I consistently use it for safe transitions on elevated highways. If the button becomes unresponsive, it might indicate a fuse or wiring issue requiring service checks.
