What is the Side Rear Vehicle Alert Function?

Rear vehicle warning light will illuminate, this is the Lane Change Assist system. Below is relevant information: 1. Introduction: During driving, due to vehicle body design, the visual range provided by side mirrors always has some blind spots. Drivers cannot constantly turn their heads, which actually increases driving risks. 2. Principle: The Lane Change Assist system alerts the driver to approaching vehicles from behind through indicators in the left/right mirrors or other locations. This system automatically activates only when changing lanes above 60 km/h, and won't function at lower speeds. It can detect vehicles approaching from up to 50 meters in the side rear area.
I particularly value this side and rear cross-traffic alert feature because, as a parent who frequently shuttles kids around, it has literally saved my life several times during actual driving. Simply put, when you're reversing or changing lanes, the system detects vehicles suddenly approaching from the side or rear and alerts you via dashboard warning lights or beeping sounds. My family's SUV has this feature—every time I back up in a mall parking lot and a car comes from the blind spot, the warning light immediately flashes, letting me know to hit the brakes. It's usually powered by radar sensors installed on the rear side bumpers to scan surrounding movements, reducing rear-end collision risks. I think this feature not only prevents minor accidents but also makes driving easier for beginners, ultimately making roads safer overall. Without it, I’d probably have had a few more scrapes by now—totally worth it!
