Levin's automatic emergency braking triggering conditions require the ACC adaptive cruise control system to be activated. When the vehicle's computer detects a potential collision risk, it will automatically apply the brakes. ACC Adaptive Cruise Control System: The ACC adaptive cruise control system refers to an intelligent automatic control system developed based on existing cruise control technology. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while wheel speed sensors collect speed signals. When the distance to the vehicle ahead becomes too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to appropriately apply wheel braking and reduce engine power output, maintaining a safe distance from the vehicle ahead. Pre-Collision System: The vehicle is equipped with pre-collision systems both front and rear. Whether driving normally or reversing, the vehicle will automatically brake to a stop. If an abnormal situation is detected ahead, the system will activate automatic braking to prevent accidents. The two vehicle model logos are arranged front and back with a gap in between, featuring a ruler-like mark below. The automatic braking function operates at speeds below 100 km/h - when an obstacle is detected ahead and the driver fails to brake, the automatic braking function will activate.

As someone who has driven this car, I find the 2021 Leiling's automatic emergency braking system quite reliable. It primarily relies on the millimeter-wave radar and camera at the front to monitor the road ahead, and it's most likely to activate when the speed is between 10 to 180 km/h. If the car in front suddenly slows down or stops, or if a pedestrian crosses the road or a bicycle darts out, the system will first sound a warning to alert you. If I don't hit the brakes, it immediately applies the brakes itself to prevent a collision. This feature is especially effective in traffic jams—I once narrowly avoided rear-ending the car in front thanks to it. Just remember to keep the sensors clean and free from mud, as dirt can affect their accuracy. It's a good habit to wipe the front of the car and the windshield regularly. The system's performance may degrade in bad weather, but overall, it significantly enhances safety and is truly dependable.

I often drive the Levin on long-distance trips and notice that the automatic emergency braking mostly activates on highways when the vehicle ahead brakes suddenly or there's an obstacle at a curve, triggering at speeds above 10 km/h. The system beeps upon detecting a risk and automatically applies the brakes to prevent collisions. This thoughtful design serves as an extra safety net, especially during fatigue driving. I'd recommend owners regularly check if the sensors function properly without obstruction, and adjust the sensitivity via in-car menu settings to prevent false alarms. Over time, you'll appreciate it as a handy little assistant that makes daily driving more worry-free—though it can't fully replace human judgment, so remember to actively brake when necessary for safety.

From a safety perspective, the automatic emergency braking system in the 2021 Levin primarily focuses on collision prevention. When driving between 10-180km/h, the system detects rapid approach from vehicles ahead or pedestrians entering the lane, issues a warning, and automatically applies the brakes. This significantly enhances driving safety. With over a decade of driving experience, I deeply appreciate the importance of this feature, especially during urban rush hours where it substantially reduces accident risks. I recommend keeping the default settings to ensure the system remains active, but avoid over-reliance as response times may delay in severe weather conditions. Maintaining situational awareness remains the most reliable approach.

When repairing cars, it's common for Levin owners to inquire about the automatic braking system. The triggering condition is when the sensors detect objects like vehicles or pedestrians abnormally close at moderate speeds. The system alerts first, and if there's no response, the brakes engage. However, I've encountered a few instances of false triggers, such as radar signal interference on winding roads. It's recommended to clean dirt from the front of the car and calibrate the camera to prevent misjudgments. In daily driving, the sensitivity can be adjusted to avoid nuisance from minor issues, but the function itself is trustworthy and can reduce the risk of rear-end collisions.

I often use the Levin to take my kids to and from school. The automatic emergency braking mainly activates when the speed is moderate, and the car in front suddenly stops or a pedestrian rushes out. The system beeps and then brakes automatically. During rush hours, it has helped a lot in avoiding scratches. The sensors on the front-mounted device, so remember not to get too close and leave some space for the system to react. Keep the settings at a moderate level and don't turn it off to prevent accidents. The effect is weaker in rain or snow, so just drive more carefully.
