Hyundai Ioniq: Driving your vehicle / Lane Keeping Assist (LKA) System

Hyundai Ioniq (AE) 2017-2024 Owner's Manual / Driving your vehicle / Lane Keeping Assist (LKA) System

Hyundai Ioniq. Lane Keeping Assist (LKA) System

The Lane Keeping Assist (LKA) System helps detect lane markers on the road with a camera at the front windshield, and assists the driver's steering to help keep the vehicle between lanes.

When the system detects the vehicle straying from its lane, it alerts the driver with a visual and audible warning, while applying a slight countersteering torque, to try to prevent the vehicle from moving out of its lane.


The Lane Keeping Assist (LKA) System is not a substitute for safe driving practices, but a convenience function only. It is the responsibility of the driver to always be aware of the surrounding and steer the vehicle.


Take the following precautions when using the Lane Keeping Assist (LKA) System:

  • Do not steer the steering wheel suddenly when the steering wheel is being assisted by the system.
  • LKA system helps to prevent the driver from moving out of the lane unintentionally by assisting the driver's steering. However, the driver should not solely rely on the system but always pay attention on the steering wheel to stay in the lane.
  • The operation of the LKA system can be canceled or not work properly according to road condition and surroundings. Always be cautious when driving.
  • Do not disassemble the LKA system camera temporarily to tint the window or attach any types of coatings and accessories. If you disassemble the camera and assemble it again, take your vehicle to an authorized HYUNDAI dealer and have the system checked for calibration.
  • When you replace the windshield glass, LKA system camera or related parts of the steering wheel, take your vehicle to an authorized HYUNDAI dealer and have the system checked for calibration.
  • The system detects lane markers and controls the steering wheel by a camera, therefore, if the lane markers are hard to detect, the system may not work properly. Please refer to "Limitations of the system".
  • Do not remove or damage the related parts of LKA system.
  • You may not hear a warning sound of LKA system because of excessive audio sound.
  • Do not place objects on the dashboard that reflects light such as mirrors, white paper, etc. The system may malfunction if the sunlight is reflected.
  • Always have your hands on the steering wheel while the LKA system is activated. If you continue to drive with your hands off the steering wheel after the "Keep hands on steering wheel" warning message appears, the system will turn off automatically. After then, if you drive with your hands on the steering wheel, the control will be activated again.
  • The steering wheel is not continuously controlled so if the vehicle speed is at a higher speed when leaving a lane the vehicle may not be able to be controlled by the system. The driver must always follow the speed limit when using the system.
  • If you attach objects to the steering wheel, the system may not assist steering or the hands off alarm may not work properly.
  • While other beeps such as the seat belt warning sound are in operation and override the LKA alarming system, LKA system beeps may not occur.

Detecting pedestrians
