Highway Driving Assist and Highway Lane Change Assist may operate abnormally or unexpectedly under the following circumstances:

  • If the operation of Lane Following Assist is limited, the operation of Highway Driving Assist and its subordinate functions will also be limited. For detailed limitations of Lane Following Assist, refer to Limitations of Lane Following Assist.

  • If the operation of Smart Cruise Control is limited, the operation of Highway Driving Assist will also be limited. For more information, refer to Limitations of Smart Cruise Control.

  • For detailed limitations of the front camera, front radar, front corner radar, and rear corner radar sensors, refer to Detecting sensor(s), as well as Limitations of Forward Collision-Avoidance Assist and Limitations of Blind-Spot Collision-Avoidance Assist.

  • Traveling to a country where operation is not supported.

  • The map information differs from the actual road because the navigation system is out of date.

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

  • The infotainment system is overloaded due to simultaneously performing functions such as route search, video playback, voice recognition, and so on.

  • GPS signals are blocked when you drive in areas such as a tunnel.

  • You veer off-course, reset the navigation route by changing the destination (including changing the route according to real-time traffic information), or cancel the route to the destination.

  • Some lanes are temporarily restricted.

  • The middle of the road does not have a physical separation structure, such as a center median.
