Hyundai Tucson: Navigation-Based Smart Cruise Control (NSCC) / Limitations of Navigation-based Smart Cruise Control

Navigation-based Smart Cruise Control may not operate normally if:

  • The navigation system is not working properly.
  • Map information is not transmitted due to an issue with the infotainment system.
  • Speed limit and road information in the navigation system has not been updated.
  • The map information differs from the actual road conditions because of real-time GPS data or map information error.
  • The navigation system is searching for a route while driving.
  • GPS signals are blocked in an area such as tunnel.
  • A road is divided into two or more roads and they join again.
  • You go off the route set in the navigation system.
  • The route to the destination is changed or canceled by resetting the navigation system.
  • 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).
  • The navigation system is updated while driving or restarts.
  • The speed limits of some sections have changed according to the road situations (e.g. construction zone).
  • You are driving on a road that is under facility construction.
  • You are driving in lane-restricted driving situations.
  • There is inclement weather, such as heavy rain or heavy snow.
  • You are driving on a road with sharp curves.

1: Set route, 2: Driving route, 3: Main road, 4: Curved road section

  • When your vehicle continues on the controlled access road and does not follow the navigation route to exit the highway, Highway Auto Curve Slowdown may not operate until it is determined that you are driving on the highway. When Highway Auto Curve Slowdown operates, your vehicle may decelerate gradually or rapidly depending on the distance to the curve and the vehicle speed.

1: Set route, 2: Branch line, 3: Driving route, 4: Main road, 5: Curved road section

  • When your vehicle does not follow the navigation route and exits the highway at an interchange or junction, Highway Auto Curve Slowdown may temporarily operate until it is determined that you have exited the highway.

1: Driving route, 2: Branch line, 3: Curved road section, 4: Main road

  • If there is no destination set on the navigation, Highway Auto Curve Slowdown operates based on the curve information for the controlled access road in the navigation system. When you exit the highway at an interchange or junction, Highway Auto Curve Slowdown may temporarily operate using the navigation information for the highway.

WARNING

Always have your eyes on the road. It is your responsibility to avoid violating traffic laws. Navigation-based Smart Cruise Control is not a substitute for safe driving practices, but a supplemental function only.

To prevent serious injury or death:

  • Always check the speed limit while driving. The navigation’s speed limit information may differ from the actual speed limit on the road.
  • Navigation-based Smart Cruise Control is automatically canceled when you leave the highway and enter a general road, interchange, junction, or rest area.
  • Navigation-based Smart Cruise Control may not operate depending on the configuration of vehicles detected ahead on the road.
  • When you are towing a trailer or another vehicle, turn off Navigationbased Smart Cruise Control.
  • After you pass through a tollbooth on a highway, Navigation-based Smart Cruise Control operates based on the outermost lane. If you enter one of the other lanes, Navigation-based Smart Cruise Control may not operate properly.
  • Your vehicle accelerates if you depress the accelerator pedal while Navigation-based Smart Cruise Control is operating. If the accelerator pedal is not depressed far enough, your vehicle may decelerate.
  • If you accelerate and release the accelerator pedal while Navigationbased Smart Cruise Control is operating, your vehicle may not decelerate sufficiently or may rapidly decelerate.
  • If the curve is too sharp or if it is a slight curve, Navigation-based Smart Cruise Control may not operate.

Information

  • There may be a gap in time between the navigation system’s guidance and when the Navigation-based Smart Cruise Control operation starts and ends.
  • The speed information on the instrument cluster may differ from the navigation system.
  • Even if you are driving at a speed lower than the Smart Cruise Control's set speed, acceleration may be limited by the curves ahead on the road.
  • If Navigation-based Smart Cruise Control is operating while leaving the highway and entering an interchange, junction, or rest area, the function may continue to operate for a while.
  • Deceleration by Navigation-based Smart Cruise Control may not feel sufficient due to the road conditions such as uneven road surfaces or narrow lanes.
