What does the 'hold' indicator on the car dashboard mean?

The 'hold' on the car refers to the auto-hold function. The introduction and working principle of the auto-hold function are as follows. Introduction to auto-hold: Auto-hold is an automatic braking function. After activating this function, for example, when stopping at a traffic light, you don't need to pull the handbrake, avoiding the use of the handbrake or electronic handbrake to simplify operations. For automatic transmission models, it also eliminates the need for frequent shifting between D to N or D to P. Working principle of auto-hold: The auto-hold function provides precise parking force through a slope sensor controlled by a controller. During startup, the parking control unit calculates information from sensors such as clutch distance, clutch engagement speed, and throttle pedal. When the driving force exceeds the running resistance, it automatically releases the parking brake, allowing the car to start smoothly.
When driving, I often see 'HOLD' displayed on the dashboard, which represents the vehicle's automatic parking hold function. This means that when you stop at a red light or in traffic, the system will automatically help you brake, so you don't have to keep pressing the brake pedal, and your foot can relax—especially convenient in congested urban areas. However, it only activates when the speed is below a certain level and the brake is pressed. A light tap on the accelerator will automatically release it and continue driving. I've tried using this function on downhill or slippery roads, and it can prevent the vehicle from sliding unexpectedly. Don't use it as a permanent brake, though—the system is designed to reduce fuel consumption and emissions during startup. If a warning appears but the car is still moving, there might be a fault, so get the braking system checked immediately.
I'm the type who enjoys exploring the little features in cars. The 'HOLD' light on the dashboard indicates that the car's brake hold system is active, usually part of the auto start-stop system. Once the car comes to a complete stop, it locks the brakes. I use it often during my daily commute, like at traffic lights—once stopped, the light comes on, and I don’t have to press hard, feeling much more effortless than regular braking. This feature also saves a bit of fuel by reducing frequent starts. However, not all cars are the same; some high-end models might integrate hill-start assist to prevent rolling. Remember, just gently press the accelerator to disengage it. If the light keeps flashing or stays on, it could be a sensor issue or software glitch, requiring professional diagnosis.
As a family driver, I believe the 'HOLD' indicator on the dashboard primarily serves as a reminder that the vehicle's automatic braking system is activated. It automatically keeps the car stationary when parked, preventing distractions. I frequently encounter this feature when dropping off or picking up my kids from school—waiting by the roadside for them to get in, the system helps hold the car steadily, which is very convenient. However, it's important to note that it may fail under certain conditions, such as on steep slopes or uneven road surfaces. I recommend checking the surroundings for safety before using this feature each time. Additionally, if the system displays an error, you can try restarting the engine or resetting the settings.
