Hyundai Tucson: Highway Driving Assist (HDA) / Highway Driving Assist Malfunction and Limitations

Highway Driving Assist malfunction

When Highway Driving Assist is not working properly, the "Check Highway Driving Assist (HDA) system" warning message may appear, and the warning light may illuminate on the instrument cluster. Have the vehicle inspected by an authorized HYUNDAI dealer.

WARNING

Always check road conditions, and if necessary, take appropriate actions to drive safely. Highway Driving Assist is a supplemental function only and it is not a self driving or autonomous driving system.

To prevent serious injury or death:

  • Always have your hands on the steering wheel while driving.
  • Always have your eyes on the road and pay attention. It is your responsibility to avoid violating traffic laws.
  • Highway Driving Assist may not be able to recognize all traffic situations and may not detect possible collision hazards. Obstacles such as vehicles, motorcycles, bicycles, pedestrians, or unspecified objects or structures (e.g. guardrails and tollbooth) may not be detected.
  • Highway Driving Assist turns off automatically under the following situations:
    - You are driving on roads that Highway Driving Assist does not operate, such as rest area, intersection, junction, etc.
    - The navigation does not operate properly such as when the navigation system is updating or restarting.
  • Highway Driving Assist may inadvertently operate or turn off depending on the road conditions (based on the navigation system information) and surroundings.
  • Lane Following Assist may be temporarily disabled when the front view camera cannot detect lanes properly or the hands-off warning is on.
  • The hands–off warning message may appear early or late depending on how the steering wheel is held or road conditions.
  • You may not hear the audible warning of Highway Driving Assist if the surrounding environment is too noisy.
  • When your vehicle is driven at high speeds through a curve, your vehicle may depart from your driving lane if you do not maintain control.
  • When you are towing a trailer or another vehicle, turn off Highway Driving Assist.
  • Highway Driving Assist may not operate right after the engine is started or when the sensors or navigation system is initialized.

Limitations of Highway Driving Assist

Highway Driving Assist may not operate normally or may not operate if:

  • The map information differs from the actual road conditions because the navigation system has not been updated, or there is a real-time GPS data or map information error.
  • The infotainment system is overloaded by simultaneously performing functions such as route search, video playback, voice recognition, etc.
  • GPS signals are blocked in an area such as tunnel.
  • You depart from the navigation route or the route to the destination is changed or canceled.
  • Your vehicle enters a service station or rest area.
  • Android Auto or Car Play is operating.
  • The navigation system cannot detect the current vehicle position (e.g. elevated roads including overpass adjacent to general roads or nearby roads exist in a parallel way).
  • A trailer or hitch mounted carrier is connected to your vehicle.
