Navigation-based Smart Cruise Control may operate abnormally or unexpectedly under the following circumstances:

• The navigation system is not working properly.

• Map information is not transmitted due to abnormal operation of the infotainment system screen.

• Map information differs from the actual road because of real-time GPS data or map information errors.

• The navigation is searching for a route while you are driving.

• GPS signals are blocked, such as in a tunnel.

• Traveling to a country where operation is not supported.

• Android Auto™ or Apple CarPlay® is operating.

• The controllable target (curved section) is close to the vehicle

• The main lanes split into two or more and then merge

• Not driving along the navigation-guided route

• The destination is reset to recalculate the route (including real-time traffic-based recalculation) or the destination setting is canceled

• Driving on the entrances or exits of rest areas or drowsy driver rest areas on a dedicated road

• Short sections of splits or merges occur consecutively

• Lanes are added or removed in sections other than splits or merges

• Driving on roads without map information

• The performance of sensors detecting objects around the vehicle is at its limit

• Lane markings are unusual or of poor quality

• The navigation system cannot detect the vehicle’s current position (for example, you are driving on elevated roads, including overpasses adjacent to general roads or nearby parallel roads).

• The navigation system updates while you are driving.

• The navigation system restarts while you are driving.

• The speed limit of some sections of the road changes.

• You are driving on a road under construction.

• You are driving on a controlled road.

• You are driving in bad weather, such as heavy rain or snow.

• You are driving on a sharply curved road.

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

• If the vehicle determines that the driving path is the main road of the dedicated roadway rather than the guided route, the Auto Highway Speed Change Adjustment function is activated. However, depending on the distance between the vehicle’s current position and the curved section, as well as the vehicle’s current speed, acceleration or deceleration may be insufficient or may occur abruptly.

• When the navigation route (main road) and driving route (branch line) differ, the Highway Curve Zone Auto Slowdown function temporarily operates based on the main road curve information.

• When the navigation system determines that you are driving off-route by entering the highway change or junction, Highway Curve Zone Auto Slowdown function does not operate.

• If you do not set a navigation destination, 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 based on navigation information about the curved section of the highway.
