Hyundai Ioniq (AE): Forward Collision-Avoidance Assist (FCA) system / FCA Sensor

Hyundai Ioniq. FCA Sensor

In order for the FCA system to operate properly, always make sure the radar sensor cover is clean and free of dirt, snow, and debris. Dirt, snow, or foreign substances on the lens may adversely affect the sensing performance of the sensor.

NOTICE

  • Do not apply license plate frame or foreign objects such as a bumper sticker or a bumper guard near the radar sensor. Doing so may adversely affect the sensing performance of the radar.
  • Always keep the radar sensor 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.
  • Be careful not to apply unnecessary force on the radar sensor or sensor cover. If the sensor is forcibly moved out of proper alignment, the FCA system may not operate correctly. In this case, a warning message may not be displayed. Have the vehicle inspected by an authorized HYUNDAI dealer.
  • If the front bumper becomes damaged in the area around the radar sensor, the FCA system may not operate properly. Have the vehicle inspected by authorized HYUNDAI.
  • Use only genuine parts to repair or replace a damaged sensor or sensor cover. Do not apply paint to the sensor cover.

NOTICE

  • NEVER install any accessories or stickers on the front windshield, nor tint the front windshield.
  • NEVER locate any reflective objects (i.e. white paper, mirror) over the dashboard. Any light reflection may cause a malfunction of the system.
  • Pay extreme caution to keep the camera out of water.
  • NEVER disassemble the camera assembly, nor apply any impact on the camera assembly.
  • Playing the vehicle audio system at high volume may offset the system warning sounds.
