What is the function of the hold button in a car?

The function of the hold button in a car is gear locking. Pressing the hold button locks the gear in the current position, allowing it to be locked in any gear of an automatic transmission car (except for P, R, and N gears). The transmission in hold mode maintains a specific gear, making the automatic transmission work similarly to a manual transmission. The hold button can prevent the car from rolling when parking briefly on a slope or in traffic jams. When using this button, even in D gear, there is no need to keep pressing the brake pedal. To release it, simply press the accelerator pedal, and it will automatically disengage when the driving force exceeds the resistance, so there is no need to shift to neutral. For long-term parking, it is best to shift to neutral or P gear and engage the handbrake system.
The first time I drove, I was completely confused about the HOLD button, but later I found it incredibly useful. In an automatic transmission car, such as when stopping at a red light or in traffic, pressing the HOLD button automatically maintains the braking state, eliminating the need to keep pressing the brake pedal. This saves a lot of effort, especially during long drives. I use it daily during my commute in traffic—once the car stops, it activates, preventing rollback, and automatically releases when I press the accelerator to start moving. Its core function is to enhance driving convenience and safety while reducing foot fatigue. Modern cars are equipped with this feature, and I recommend new drivers give it a try. It operates based on an electronic system controlling hydraulic braking, making it simple, easy to use, and reliable. Just remember not to press it while driving—only use it when the car is stopped to avoid unnecessary issues. Overall, it makes daily driving much more relaxed and comfortable.
As a seasoned driver who frequently navigates mountainous areas, I absolutely love the performance of the HOLD button on steep slopes. When driving an automatic transmission car uphill or downhill, pressing this button locks the transmission, providing stable braking effect to prevent the car from slipping or losing control due to excessive speed. Once during a trip through treacherous mountain roads, I might have had an accident without it. The HOLD button automatically keeps the wheels fixed, and you just need to lightly press the accelerator when ready to start. This feature isn't just for show—it's a practical tool, especially on slippery roads or steep inclines. It also integrates with the car's sensor technology to ensure safety comes first. So, I recommend checking if the button is functioning properly before every trip, making it a habit to prevent accidents.
