BSM (Blind-Spot Monitoring)
This system uses millimeter-wave radar to detect other vehicles on the adjacent lanes.
Aside from detecting the vehicles at your back, it also helps draw attention to adjacent vehicles in you blind spot that may be approaching you.
While driving, when it detects a vehicle in your blind spot, the LED indicator lights will illuminate on the side mirror. If you switch on your turn signal at this time, the light will begin to flash in order to draw your attention and let you know there’s a vehicle in your side.
