This is the airbag warning light, which typically appears during vehicle startup for self-check and extinguishes after a few seconds. Below is relevant information: 1. Airbag composition: Automotive airbags mainly consist of airbag sensors, collision safety airbags, and electronic control devices. The driver-side collision airbag is installed in the steering wheel, while the passenger-side collision airbag is usually mounted on the dashboard. 2. Airbag : Automotive airbag quality becomes unreliable after 8-10 years of use, so it's recommended to perform maintenance every 10,000-20,000 kilometers. If airbag replacement is needed, choose authorized service centers for replacement.

Did you see the yellow warning light on the dashboard showing a person holding a ball? That's the pre-collision safety system status indicator. It might be because the camera above the windshield is obstructed, perhaps by fog or too many insect remains. Or the millimeter-wave radar could be covered with mud splatters—it's located right behind the car emblem. In such cases, features like automatic emergency braking and lane departure warning will stop working, which can be quite dangerous. Once after rain, I forgot to clean the radar sensor before driving, and this light came on too. Find a safe place to pull over, thoroughly clean the sensor and windshield area, and then restart the engine—the light usually goes away after that.

The yellow figure holding a ball icon on your dashboard is mostly an active safety system alert, just like what I encountered last time. It doesn't necessarily mean hardware failure. There are three common causes: the sensor probe at the upper middle part of the windshield is dirty, the front radar is obstructed by foreign objects, or the millimeter-wave radar needs calibration. It's most easily triggered when mud splashes near the emblem during heavy rain. Focus on checking the area around the front license plate where the sensor module is hidden. You can clean it for 5 minutes after turning off the engine and then restart. If the light remains on, it indicates calibration is needed, but some models will automatically recover after self-checking at speeds over 40km/h.

The person holding a ball icon is actually the pre-collision system warning light, primarily responsible for autonomous emergency braking. However, unlike ABS red warning lights, this indicates an issue with the driver assistance system. Last weekend after washing my car, this light also came on because the high-pressure water jet displaced the millimeter-wave radar under the license plate bracket. It's important to know that many vehicles' front collision systems consist of two parts: passive (bumper safety design) and active (which relies on cameras and radars to detect obstacles). Warnings can be triggered when the sensor area is covered by snow/ice or when wiring becomes loose after rough driving.

This is the malfunction indicator for the pre-collision protection system. In models, it's called 'Pedestrian Detection System Malfunction,' while BMW displays it as the Collision Warning icon. Essentially, they all indicate that your active safety assistance features are limited. My advice is to immediately check four key areas at the front of the vehicle: inspect the camera lens glass at the top of the windshield for cracks; check if any plastic panels near the fog lights are misaligned; ensure the sensor areas near the license plate are clean; and finally, open the hood to verify that the wiring harness connectors are securely plugged in. Toyota owners should pay special attention—last year, the Avalon experienced numerous false alarms due to water ingress in the radar cover.

That little yellow figure holding a ball symbol lighting up should be taken seriously. It indicates a failure in the vehicle's active safety protection system, commonly seen in German cars like and Audi. Possible causes include sensor interference from strong magnetic fields (e.g., after passing high-voltage power stations) or radar bracket misalignment over 3mm due to front-end collisions. I once had to visit a repair shop on the Qinghai-Tibet Highway because of this - it turned out to be caused by a deformed license plate frame triggering the alarm. When the light comes on, immediately reduce speed and turn on hazard lights to alert following vehicles. Never continue relying on automatic braking functions - the safest approach is to directly contact a 4S dealership to check the fault codes.
