Kia Telluride: Navigation-based Smart Cruise Control (NSCC): (if equipped) / Navigation-based Smart Cruise Control limitations

The advanced Navigation-based Smart Cruise Control (NSCC) system equipped in your Kia Telluride is designed to proactively adjust your vehicle's speed using real-time map data. However, this sophisticated technology operates within defined boundaries. You should be aware that the system may function abnormally or exhibit unexpected behavior under the following specific conditions:

• The onboard navigation system is experiencing a technical fault or is otherwise not functioning as intended.

• Vital mapping and routing information fails to reach the cruise control module due to an error in the infotainment system display or the vehicle’s central processing unit.

• Discrepancies exist between the digital map data and the physical road layout, often caused by outdated map files or errors in real-time GPS positioning data.

• The navigation system is actively calculating or recalculating a route while the Kia Telluride is in motion, which may cause a temporary delay in speed adjustment data.

• A disruption in satellite connectivity, such as while driving through long tunnels, parking structures, or dense urban canyons, which causes a loss of precise GPS signals.

• Operating the vehicle in a geographical region where the navigation-based support features are not yet mapped or supported by the system.

• When the infotainment system is prioritizing the interface for Android Auto™ or Apple CarPlay®, which may occasionally limit the transmission of native navigation data to the cruise control system.

• The vehicle is approaching a curved road section that is located too close to the current vehicle position for the system to safely execute a gradual speed adjustment.

• Navigating complex highway infrastructure where the main lanes split into multiple diverging paths and subsequently merge, causing potential confusion in route identification.

• You are driving on a path that does not align with the active turn-by-turn guidance currently set in the Kia Telluride navigation system.

• The destination is being modified or canceled mid-drive—including automatic re-routing triggered by live traffic updates—which resets the system's look-ahead parameters.

• Entering or exiting highway rest areas, service plazas, or specialized pull-off zones, where the map data may not categorize the lanes as part of the "main" road.

• When multiple lane splits or merges occur in rapid succession, preventing the system from maintaining a consistent "main road" lock.

• Driving on newly constructed roads or temporary lanes that have not yet been reflected in the current navigation database.

• The system is driving on roads for which there is no available digital map information, rendering the navigation-based speed adjustment feature inactive.

• The external environmental sensors (radar and camera) are operating at their maximum detection limit due to high-traffic complexity or signal interference.

• Road lane markings are faded, non-existent, or of such poor quality that the system cannot reliably map the current lane position.

• The navigation system cannot discern the vehicle’s precise elevation or position, such as when driving on an elevated overpass that runs parallel to or directly above a surface-level road.

• The vehicle’s navigation software is undergoing an background update while you are actively driving, which may temporarily suspend data processing.

• The navigation system initiates an automatic restart due to a minor software glitch or power cycle while in operation.

• You are traveling through road segments where speed limits are frequently changed or are currently inconsistent with the navigation system’s stored data.

• The road is currently undergoing active construction, which often results in lane closures, detours, and altered traffic flows that deviate from standard map data.

• Driving on roads with restricted access, military bases, or privately controlled facilities that are not mapped in the public navigation database.

• Operating the Kia Telluride in severe weather conditions, including torrential rain, blinding snow, or dense fog, which hampers both the sensor suite and the reliability of navigation data.

• Navigating through extremely tight or sharply curved roads that exceed the geometric parameters defined for automatic speed reduction.

Set route Branch line Driving route Main road Curved road section

• When there is a discrepancy between the navigation set route (branch line) and your current driving path (main road), the "Highway Curve Zone Auto Slowdown" may not activate until the Kia Telluride system successfully re-synchronizes and confirms the current road as the primary route.

• If the vehicle identifies the path as a main roadway rather than the navigation-guided route, the "Auto Highway Speed Change" may trigger. However, the intensity of acceleration or deceleration may vary based on your distance to the curve and your current speed, potentially resulting in abrupt transitions.

Main road Branch line Driving route Set route Curved road section

• In cases where the navigation main road and your actual driving path (the branch line) differ, the "Highway Curve Zone Auto Slowdown" function may provide brief, temporary operation based solely on the main road's curve characteristics.

• If the navigation system senses that you are exiting the highway via a junction or connector, the "Highway Curve Zone Auto Slowdown" function will be suppressed to avoid unnecessary braking.

Driving route Branch line Curved road section Main road

• In the event that you do not define a specific navigation destination, the "Highway Curve Zone Auto Slowdown" in your Kia Telluride will still function by relying on default curve information mapped for the primary road.

• Even after you have intentionally departed from the main road, the system may exhibit temporary speed reduction behavior if it still retains navigation data regarding the upcoming highway curved sections.
