Note: The Kia EV9 launched in the United States for the 2024 model year. Highway Driving Pilot (HDP) is Kia's Level 3 autonomous driving feature available on certain EV9 trims in specific markets. If you're experiencing HDP issues, this guide explains the system and troubleshooting approaches.
What Highway Driving Pilot Is
Highway Driving Pilot is a conditional hands-free and eyes-off driving system operating at SAE Level 3 automation. Unlike Level 2 systems that require constant attention, HDP allows the driver to divert attention under specific conditions. Availability varies by market and is subject to regulatory approval.
HDP uses lidar, cameras, radar, and HD mapping to enable automated driving on designated highways. The system monitors its operational boundaries and requests driver takeover when necessary.
Common Error Causes
Road compatibility issues prevent HDP engagement. The system only works on specific pre-mapped highways meeting certain criteria. Attempting to use HDP on unsupported roads produces errors. Check Kia's coverage map for compatible routes.
Sensor obstruction disables advanced automation features. HDP requires clear sensor data from lidar (roof-mounted), cameras, and radar. Rain, snow, fog, or dirt on sensors causes system unavailability.
System limitations trigger handback requests. Speed limits, weather conditions, construction zones, and complex traffic situations may exceed HDP's capabilities. The system alerts the driver to resume control.
Driver Monitoring
Even with HDP active, the driver must remain in the driver's seat and responsive to takeover requests. The system monitors driver presence and readiness. Failure to respond to takeover requests triggers escalating alerts and eventual emergency stop.
Error Response
When HDP shows errors, first ensure conditions support the feature (correct road, clear sensors, appropriate weather). Verify the system is enabled in settings. If errors persist on supported roads with good conditions, dealer diagnosis may be needed to check sensors and software.
