Hyundai Ioniq: Limitations of the System / Detecting pedestrians

Hyundai Ioniq (AE) 2017-2024 Owner's Manual / Driving your vehicle / Forward Collision-Avoidance Assist (FCA) system / Limitations of the System / Detecting pedestrians

The sensor may be limited when:

  • The pedestrian is not fully detected by the camera recognition system, for example, if the pedestrian is leaning over or is not fully walking upright
  • The pedestrian is moving very quickly or appears abruptly in the camera detection area
  • The pedestrian is wearing clothing that easily blends into the background, making it difficult to be detected by the camera recognition system
  • It is difficult to detect and distinguish the pedestrian from other objects in the surroundings, for example, when there is a group of pedestrians or a large crowd
  • There is an item similar to a person’s body structure
  • The pedestrian is small
  • The pedestrian has impaired mobility
  • The sensor recognition is limited
  • The radar sensor or camera is blocked with a foreign object or debris
  • Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera
  • The outside lighting is too bright (e.g. when driving in bright sunlight or in sun glare) or too dark (e.g. when driving on a dark rural road at night)
  • When light coming from a street light or an oncoming vehicle is reflected on a wet road surface such as a puddle in the road
  • The field of view in front is obstructed by sun glare
  • The windshield glass is fogged up; a clear view of the road is obstructed
  • The adverse road conditions cause excessive vehicle vibrations while driving


  • Do not use the Forward Collision-Avoidance Assist (FCA) system when towing a vehicle. Application of the FCA system while towing may adversely affect the safety of your vehicle or the towing vehicle.
  • Use extreme caution when the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance.
  • The FCA system is designed to help detect and monitor the vehicle ahead or help detect a pedestrian in the roadway through radar signals and camera recognition. It is not designed to detect bicycles, motorcycles, or smaller wheeled objects such as luggage bags, shopping carts, or strollers.
  • Never try to test the operation of the FCA system. Doing so may cause severe injury or death.


In some instances, the FCA system may be canceled when subjected to electromagnetic interference.


This device complies with Part 15 of the FCC rules.

Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and

2. This device must accept any interference received, including interference that may cause undesired operation.
