Hyundai Elantra: Highway Driving Assist (HDA) / Function malfunction and limitations

System malfunction

When Highway Driving Assist or Highway Lane Change function is not working properly, the ‘Check Highway Driving Assist (HDA) system’ warning message will appear, and the warning light will illuminate on the cluster. We recommend that the function be inspected by an authorized HYUNDAI dealer.

WARNING

• The driver is responsible for controlling the vehicle for safe driving.
• Always have your hands on the steering wheel while driving.
• Highway Driving Assist is a supplemental function that assists the driver in driving the vehicle and is not a complete autonomous driving system. Always check road conditions, and if necessary, take appropriate actions to drive safely.
• Always have your eyes on the road, and it is the responsibility of the driver to avoid violating traffic laws. The vehicle manufacturer is not responsible for any traffic violation or accidents caused by the driver.
• Highway Driving Assist may not be able to recognize all traffic situations. The function may not detect possible collisions due to limitations of the system. Always be aware of the limitations of the system. Obstacles such as vehicles, motorcycles, bicycles, pedestrians, unspecified objects, structures, etc. that may collide with the vehicle may not be detected.
• Highway Driving Assist will turn off automatically under the following situations:
  - Driving on roads that the system does not operate, such as a rest area, intersection, junction, etc.
  - The navigation does not operate properly such as when the navigation is being updated or restarted
• Highway Driving Assist may inadvertently operate or turn off depending on road conditions (navigation information) and surroundings.
• Lane Following Assist function may be temporarily disabled when the front view camera cannot detect lanes properly or the hands-off warning is on.
• You may not hear the warning sound of Highway Driving Assist if the surrounding is noisy.
• If the vehicle is driven at high speed above a certain speed at a curve, your vehicle may drive to one side or may depart from the driving lane.
• When you are towing a trailer or another vehicle, we recommend that Highway Driving Assist is turned off due to safety reasons.
• The hands–off warning message may appear early or late depending on how the steering wheel is held or road conditions. Always have your hands on the steering wheel while driving.
• For your safety, please read the owner's manual before using the Highway Driving Assist.
• Highway Driving Assist will not operate when the engine is started, or when the detecting sensors or navigation is being initialized.

Limitations of the function

Highway Driving Assist may not operate normally, or may not operate under the following circumstances:

• The map information and the actual road is different because the navigation is not updated
• The map information and the actual road is different because of 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 areas such as a tunnel
• The driver goes off course or the route to the destination is changed or canceled by resetting the navigation
• The vehicle enters a service station or rest area
• Android Auto or Car Play is operating
• The navigation cannot detect the current vehicle position (ex: elevated roads including overpass adjacent to general roads or nearby roads exist in a parallel way)
• White single dotted lane line or road edge cannot be detected
• The road is temporarily controlled due to construction, etc.
• There is no structure, such as a medium strip, guardrails, etc., on the road
