AUTOH refers to the automatic handbrake or auto hold. Here is its detailed introduction: 1. Definition: AUTOH, also known as automatic handbrake or auto hold, is a function that automatically brakes the vehicle through the ABS-ESP control unit. 2. Function: The AUTOH auto hold function provides precise braking force via the slope sensor controlled by the system. When starting the vehicle, the parking control unit calculates information from sensors such as the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. It automatically releases the parking brake when the driving force exceeds the running resistance, ensuring a smooth start for the vehicle.

I've been driving for many years, and Auto H is the automatic parking system, which is particularly suitable for urban congestion scenarios. Its function is that when you stop at a red light or in traffic, you don't have to keep pressing the brake pedal; the car holds itself and won't roll away. Just press the accelerator to continue driving, saving effort and making the ride smoother. The working principle is that the vehicle's sensors detect the stopped state and automatically trigger the brake lock. I use it during my daily commute, so my legs don't get sore, and it also reduces the risk of rear-end collisions. It's even safer for preventing rollback when starting on a slope. However, pay attention to the operating environment: don't use it at high speeds, and beginners should practice on flat ground first. Most automatic transmission cars have this feature, and I recommend adding this function when choosing a car to improve driving comfort. Combined with hill-start assist, it can prevent many accidents.

Safety comes first when driving. I've tried Auto H and found it quite useful—it mainly prevents the vehicle from sliding after stopping. On steep slopes or at traffic lights, it automatically locks the brakes, so you don't have to keep your foot pressed down. Just step on the accelerator to go, eliminating any risk of misoperation. The benefits include reduced fatigue and lower accident risks, especially in preventing skidding on rainy or snowy days. However, don’t rely on it entirely: if the system fails, you should know how to use the manual brake as a backup. My personal suggestion is to start with simple operations, like turning it on in congested city traffic to experience the convenience of intelligent assistance. Combine this with studying the vehicle manual to learn setup methods—some cars allow you to adjust sensitivity to better suit your habits. In short, it's a great modern driving aid.

Talking about Auto H, it's when the car automatically holds the brakes after stopping, so you don't have to worry about it. In traffic jams or at red lights, once the car comes to a complete stop, the system activates automatically, allowing you to relax your foot. Just press the accelerator to continue driving—it's super simple. I've found it really beneficial: less leg fatigue and no more anxiety about the car rolling back. Nowadays, this feature is common in new cars and is very user-friendly. However, be a bit cautious during rainy or snowy conditions, as the response might be slightly delayed. Overall, give it a try—it makes city driving much more convenient.
