Limitations of NSCC

NSCC may not operate properly under the following circumstances:

  • The navigation is not working properly

  • Speed limit and road information in the navigation is not updated

  • 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

  • A road that divides into two or more roads and rejoins

  • The driver goes off course the route set in the navigation

  • The route to the destination is changed or canceled by resetting the navigation

  • The vehicle enters a service area or rest area

  • Android Auto or Apple Car Play is operating

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

  • 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 on a road that is controlled

[1]: Set route, [2]: Branch line, [3]: Driving route, [4]: Main road, [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 your 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 will operate. Depending on the distance to the curve and the current vehicle speed, vehicle deceleration may not be sufficient or may decelerate rapidly.

[1]: Main road, [2]: Branch line, [3]: Driving route, [4]: Set route, [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 will operate based on the curve information on the main road.

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

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

  • If there is no destination set on the navigation, Highway Curve Zone Auto Slowdown function will operate 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.

WARNING

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

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

  • NSCC will automatically be canceled when you leave the highway main road. Always pay attention to road and driving conditions.

  • 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.

  • When you are towing a trailer or another vehicle, turn off NSCC.

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

  • Your vehicle will accelerate if you depress the accelerator pedal while NSCC is operating and the function will not decelerate your vehicle. If the accelerator pedal is depressed insufficiently, your vehicle may decelerate.

  • If you accelerate and releases the accelerator pedal while NSCC is operating, your 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.

NOTICE

  • 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 curve sections ahead.

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

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

This device complies with Part 15 of the FCC rules.

Operation is subject to the following three conditions:
