Hyundai Santa Fe (TM): Driving Convenience / Highway Driving Assist (HDA)

Highway Driving Assist is designed to help detect vehicles and lanes ahead, and help maintain distance from the vehicle ahead, maintain the set speed, and help center the vehicle in the lane while driving on the highway (or motorway).

Information

• The Highway Driving Assist is available only on controlled access road of certain highways.
  ÃÃControlled access road indicates roads with limited entrances and exits that allow uninterrupted high speed traffic flow. Only passenger cars and motorcycles are allowed on controlled access roads.
• Additional highways may be expanded by future navigation updates.

System operating

Highway Driving Assist will operate when entering or driving on the main road of highways (or motorways), and satisfying all the following conditions:

-- Lane Following Assist is operating
-- Smart Cruise Control is operating

Information

• While driving on the highway (or motorway), if Smart Cruise Control starts operating, Highway Driving Assist will operate.
• When entering the main roads of highways (or motorways), Highway Driving Assist will not turn on if the Lane Following Assist is turned off even when Smart Cruise Control is operating.

• Restarting after stopping

When Highway Driving Assist is operating, your vehicle will stop if the vehicle ahead of you stops. Also, if the vehicle ahead of you starts moving within 30 seconds after the stop, your vehicle will start as well. In addition, after the vehicle has stopped and 30 seconds have passed, the ‘Use switch or pedal to accelerate’ message will appear on the cluster. Depress the accelerator pedal or push the + switch, - switch or switch to start driving.

• Hands-off warning

If the driver takes their hands off the steering wheel for several seconds, the ‘Place hands on the steering wheel’ (or ‘Keep hands on the steering wheel’) warning message will appear and an audible warning will sound in stages.

First stage : Warning message

Second stage : Warning message (red steering wheel) and audible warning

If the driver still does not have their hands on the steering wheel after the hands-off warning, the ‘Highway Driving Assist (HDA) canceled’ (or ‘HDA (Highway Driving Assist) cancelled’) warning message will appear and Highway Driving Assist and Lane Change Assist will be automatically canceled.

System standby

When Smart Cruise Control is temporarily canceled while Highway Driving Assist is operating, Highway Driving Assist will be in the standby state. At this time, Lane Following Assist will operate normally.

System 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’ (or 'Check HDA (Motorway Driving Assist) system') warning message will appear, and the warning light will illuminate on the cluster. We recommend that the system 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 system 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 system 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 system

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)
