Highway Driving Assist (HDA)

HDA helps maintain a set distance and speed from the vehicle ahead while driving on a highway main section and helps center the vehicle in the lane.

  • Highway Driving Assist is available only on controlled access highways with limited entrances and exits that allow uninterrupted high speed traffic flow.

    • USA: Select Interstate Highway and U.S. (Federal) and State Highways

    • Canada: Select Provincial and Territorial Highways

  • Additional highways may be expanded by future navigation system updates.

  • Highway Driving Assist does not operate on interchanges or junctions.

  • Some Highway Driving Assist operations may change if Emergency Stop is equipped. Make sure to familiarize yourself with the Emergency Stop function. For more information, refer to Emergency Stop (ES).
