Hyundai Elantra: Driving Safety / Forward Collision–Avoidance Assist (FCA) (sensor fusion)

Hyundai Elantra (CN7) 2021-2024 Owner's Manual / Driver assistance system / Driving Safety / Forward Collision–Avoidance Assist (FCA) (sensor fusion)

Basic function

Forward Collision-Avoidance Assist is designed to help detect and monitor the vehicle ahead or help detect a pedestrian or cyclist in the roadway and warn the driver that a collision is imminent with a warning message and an audible warning, and if necessary, apply emergency braking.

Junction Turning function

Junction Turning function will help avoid a collision with an oncoming vehicle in an adjacent lane when turning left at a crossroad with the turn signal on by applying emergency braking.

Detecting sensor

[1] : Front view camera, [2] : Front radar

Refer to the picture above for the detailed location of the detecting sensors.


Take the following precautions to maintain optimal performance of the detecting sensor:

  • Never disassemble the detecting sensor or sensor assembly, or apply any impact on it.
  • If the detecting sensors have been replaced or repaired, we recommend that you have your vehicle inspected by an authorized HYUNDAI dealer.
  • Never install any accessories or stickers on the front windshield, or tint the front windshield.
  • Pay extreme caution to keep the front view camera dry.
  • Never place any reflective objects (i.e. white paper, mirror) over the dashboard. Any light reflection may prevent the system from functioning properly.
  • Do not apply license plate frame or objects, such as a bumper sticker, film or a bumper guard, near the front radar cover.
  • Always keep the front radar and cover clean and free of dirt and debris. Use only a soft cloth to wash the vehicle. Do not spray pressurized water directly on the sensor or sensor cover.
  • If unnecessary force has been applied to the radar or around the radar, Forward Collision-Avoidance Assist may not properly operate even though a warning message does not appear on the cluster. We recommend that the vehicle be inspected by an authorized HYUNDAI dealer.
  • Use only genuine parts to repair or replace a damaged front radar cover. Do not apply paint to the front radar cover.
