Blind Spot Detection (BSD).

At speeds of 30 km/h or above, BSD uses radar sensors on either side of the rear bumper to detect vehicles next to and diagonally behind the Elantra. If a vehicle is present in the Elantra’s blind spot, BSD displays a visual alert in the exterior mirrors. If the driver proceeds to activate the corresponding indicator lights, a flashing visual warning is provided and an audible alert is sounded.

Available on the SR Turbo variant.
