What does HOLD mean?

In automobiles, some vehicles may have an AUTO-H or AUTO-HOLD button. Generally, the AUTO-H function on a vehicle is referred to as an automatic handbrake or automatic parking, both of which are standard features of an electronic parking brake system. The main functions include the following three points: 1. When encountering a red light or other situations requiring a short stop: AUTO-H will automatically brake the wheels after the vehicle comes to a complete stop, preventing rolling. There is no need to manually engage the handbrake. When the light turns green, simply press the accelerator to start, and the system will automatically release the wheels. 2. When starting the vehicle: AUTO-H automatically brakes to prevent rolling. Once the vehicle's power is sufficient to move forward, AUTO-H will automatically release the wheels, allowing the vehicle to proceed. 3. After parking, there is no need to pull the handbrake: The system will automatically brake the wheels at this time. However, the third function is not available on certain models, and manual handbrake engagement is still required for parking. The specific configuration depends on the vehicle. Using the AUTO-H function is very simple. After entering the vehicle, start the engine, fasten the seatbelt, close the door, and press the AUTO-H button to activate the BMW automatic parking system function. If the indicator light does not illuminate or flashes, it indicates a system malfunction.
In the automotive field, 'hold' often refers to a function button on the transmission, particularly common in automatic transmission models. I frequently use it while driving, such as when climbing steep slopes or descending hills. Pressing the hold button keeps the transmission in the current gear without automatically upshifting, providing greater engine torque and more power to the vehicle, preventing it from rolling back. The principle behind this is that the ECU control system restricts gear changes to adapt to complex road conditions. Misuse, such as driving in hold mode for extended periods on flat roads, may lead to increased fuel consumption or vehicle damage. Designs vary slightly across different car models; Nissan and Honda have similar systems, so it's best to consult the manual before operation. Flexible use of this function while driving can enhance both driving pleasure and safety.
Speaking of the meaning of 'hold,' as an ordinary car owner, I understand it as a feature that keeps the car stationary for convenience when parking. For example, my SUV has an auto hold button. After activating it, when I stop at a red light by pressing the brake, I can release my foot from the brake pedal without the car rolling, which is especially useful for hill starts. The operation is simple: press the button, and the dashboard will display 'hold.' Press the accelerator to automatically release it. This feature is very friendly to novice drivers, avoiding frequent operation of the handbrake. It's particularly practical in city traffic jams, reducing the fatigue of constantly pressing the brake. Many modern cars come standard with this feature, such as high-end models from Volkswagen and Toyota. However, don't rely on it too much; in case of system failure, you still need to be accustomed to manual control.
