Hyundai Kona: Blind-Spot Collision Warning (BCW) / Description and operation

Description

BCW is a system that measures the relative speed and distance from the following vehicles by using two electromagnetic wave radar sensors attached to the rear bumper, and detects any vehicle within the blind spot zone and gives off alarm (visual and auditory).
Blind-Spot Collision Warning Indicator (BCW) : Senses other vehicles in the BCW zone and turns on the BCW warning lamp for the driver.
Warning lamp starts blinking when the driver turns on the turn signal lamp to enter the lane where another vehicle is driving.
Lane Change Assist (LCA) : Senses other vehicles approaching at high speed in the BCW zone and turns on the BCW warning lamp for the driver.
Warning lamp starts blinking when the driver turns on the turn signal lamp without recognizing any sudden approaching vehicle from that direction.
Rear Cross Traffic Alert (RCTA) : When the vehicle is on the reverse, the RCTA generates alarm to alert another vehicle approaching from the rear and side.
