NSCC Limitations

NSCC may not operate properly under the following circumstances:

  • The navigation is not working properly

  • Map information is not transmitted due to infotainment system's abnormal operation

  • The map information and the actual road is different because of real-time GPS data or map information error

  • The navigation searches for a route while driving

  • GPS signals are blocked in areas such as a tunnel

  • The vehicle enters a service station or rest area

  • Android Auto or Car Play is operating in the infotainment system

  • The navigation cannot detect the current vehicle position (for example, elevated roads including overpass adjacent to general roads or nearby roads exist in a parallel way)

  • The navigation is being updated while driving

  • The navigation is being restarted while driving

  • The speed limit of some sections changes according to the road situations

  • Driving on a road under construction

  • Driving in lane-restricted driving situations

  • There is bad weather, such as heavy rain, heavy snow, etc.

  • The vehicle leaves the main road to enter an interchange, junction, rest area, etc.

  • You go off the route set in the navigation system

  • A road that divides into two or more roads and joins again

  • When lanes appear or disappear at sections other than the road that divides into two or mode roads.

  • When the performance of sensors that detect objects around the vehicle is at limit

  • If the lane marking (or road edge) is unusual or damaged

  5. Curved road section

  • When there is a difference between the navigation set route (branch line) and the driving route (main road), Highway Curve Zone Auto Slowdown function may not operate until the driving route is recognized as the main road.

  • When the vehicle's driving route is recognized as the main road by maintaining the main road instead of the navigation set route, Highway Curve Zone Auto Slowdown function operates. Depending on the distance to the curve and the current vehicle speed, vehicle deceleration may not be sufficient or may decelerate rapidly.

  5. Curved road section

  • When there is a difference between the navigation route (main road) and the driving route (branch line), Highway Curve Zone Auto Slowdown function may temporarily operate based on the curve information on the main road.

  • When it is judged that you are driving out of the route by entering the highway interchange or junction, Highway Curve Zone Auto Slowdown function does not operate.

  • If there is no destination set on the navigation, Highway Curve Zone Auto Slowdown function operates based on the curve information on the main road. Even if you depart from the main road, Highway Curve Zone Auto Slowdown function may temporarily operate due to navigation information of the highway curve section.

  • NSCC is not a substitute for safe driving practices, but a convenience function. Always have your eyes on the road, and it is the responsibility of the driver to avoid violating traffic laws.

  • The navigation's speed limit information may differ from the actual speed limit information on the road. It is the driver's responsibility to check the speed limit on the actual driving road or lane.

  • NSCC automatically cancels when you leave the highway main road. Always pay attention to road and driving conditions while driving.

  • NSCC may not operate due to the existence of leading vehicles and the driving conditions of the vehicle. Always pay attention to road and driving conditions while driving.

  • When you are towing a trailer or another vehicle, turn off NSCC for safety reasons. You may lose control stability.

  • After you pass through a tollbooth on a highway NSCC operates based on the first lane. If you enter one of the other lanes, NSCC might not operate properly.

  • The vehicle accelerates if the driver depresses the accelerator pedal while NSCC is operating, and the function does not decelerate the vehicle. However, if the accelerator pedal is depressed insufficiently, the vehicle may decelerate.

  • If the driver accelerates and releases the accelerator pedal while NSCC is operating, the vehicle may not decelerate sufficiently or may rapidly decelerate to a safe speed.

  • If the curve is too large or too small, NSCC may not operate.

Precautions

  • A time gap could occur between the navigation's guidance and when NSCC operation starts and ends.

  • The speed information on the instrument cluster and navigation may differ.

  • Even if you are driving at a speed lower than SCC set speed, acceleration may be limited by the speed camera or curve sections ahead.

  • If NSCC is operating while leaving the main road to enter an interchange, junction, rest area, etc., the function may operate for a certain period of time.

  • Deceleration by NSCC may feel it is not sufficient due to road conditions such as uneven road surfaces, narrow lanes, etc.
