What is Highway Driving Assist?

---

Hyundai's Highway Driving Assist (HDA) is designed to drastically reduce driver fatigue during long freeway trips or heavy stop-and-go traffic. It operates by combining the functionality of two core Hyundai SmartSense features: Smart Cruise Control with Stop & Go and Lane Following Assist.

When driving on a compatible highway, the system utilizes a front-view camera and radar sensors to automatically maintain a set distance from the vehicle ahead while providing gentle steering inputs to keep the sedan perfectly centered in its lane. For the everyday commuter, this means the vehicle handles the repetitive acceleration, braking, and steering micro-adjustments, allowing you to arrive at your destination feeling much more relaxed. For a broader look at all the safety technologies available across the lineup, review our comprehensive Elantra model overview.

When you encounter sudden rush-hour congestion, the Stop & Go functionality allows the vehicle to bring itself to a complete stop as traffic halts. If traffic begins moving again within three seconds, the Elantra will automatically resume your set speed and following distance. You can verify the specific radar and camera systems powering this technology on the Official Hyundai SmartSense Safety Page.
