What is the function of the HOLD button?

The function of the HOLD button is a derivative feature of electronic parking. The HOLD button adjusts the optimal driving state according to different road conditions, effectively preventing the transmission from frequently shifting gears on poor road surfaces and serving as a forced downshift (without upshifting) during overtaking. When the HOLD button is pressed in D gear, the transmission will remain in second, third, or fourth gear (primarily fourth gear). When pressed in 3rd gear, it will stay in second or third gear (primarily third gear). When pressed in 2nd gear, it will remain in second gear, and when pressed in 1st gear, it will stay fixed in first gear. Using this button does not harm the transmission. Scenarios where the HOLD function can be used: Slippery surfaces, such as starting on snow. Starting in 2nd gear on snow is smoother than starting in 1st gear. When starting on snow, the gear lever can be placed in position 2, and pressing HOLD will keep the transmission in the 2nd gear ratio, ensuring a smoother start. Continuous winding roads can cause the automatic transmission to shift frequently. Pressing the HOLD button in D4 gear activates the hold mode, keeping the transmission in 3rd gear. This not only reduces transmission wear but also allows the transmission to continuously deliver greater torque during driving, improving acceleration performance and ensuring a smoother ride. When driving on mountain roads or continuous slopes, pressing the HOLD button in D4 or 2nd gear activates the hold mode. This provides stronger acceleration when going uphill and greater engine braking (drag) when going downhill, enhancing safety and avoiding wear caused by frequent gear shifts.
I often like to explore the buttons in my car, and the HOLD button on the air conditioning system is particularly useful. Pressing it prevents the system from automatically adjusting the temperature. For example, when it's raining or sunny outside and the temperature in the car fluctuates significantly, it locks the current settings to maintain a constant temperature. This is very practical for long-distance driving, saving you from the hassle of the AC constantly switching between hot and cold. In some cars, it also controls seat heating or ventilation—just press it to fix the state, avoiding unnecessary switching. I've tried it several times, and after turning it on, the overall comfort improves, especially in traffic jams when you don't have to fiddle with adjustments. If your car has automatic temperature control, the HOLD button acts like a simple safety lock, preventing accidental touches or system misjudgments. The key is to understand that it's a passive stabilization function and not to confuse it with other buttons, such as the AUTO button, which actively controls airflow. Overall, this little button is designed very thoughtfully, and once you're familiar with its use, it can genuinely enhance your daily driving experience.
I often use the HOLD button during daily driving. It helps maintain a stable temperature inside the car without manual adjustments. For example, on chilly mornings, I set the temperature and press HOLD, and it stays that way; when it gets hot at noon, the car won’t automatically cool down. This is especially useful during rush hour—I just set it once and forget about it, focusing on the traffic. The difference from the regular AUTO button is that it simply locks the settings, skipping the automatic adaptation process. I find it very convenient for beginners or busy people, as it reduces stress. If your car’s AC is often unstable, try this feature—it can extend component lifespan.
