Rear Cross Traffic Collision-Avoidance Assist Malfunction and Limitations

Rear Cross Traffic Collision-Avoidance Assist Malfunction

If Rear Cross-Traffic Collision-Avoidance Assist does not operate properly, the "Check Rear Cross Traffic Safety System" warning message may appear, andthe warning light may illuminate on the instrument cluster. Have the system inspected by an authorized HYUNDAI dealer.

If the side mirror indicator does not operate properly, the "Check Side Mirror Indicator" warning message may appear andthe warning light may illuminate on the instrument cluster. Have the vehicle inspected by an authorized HYUNDAI dealer.

Rear Cross-Traffic Collision-Avoidance Assist Disabled

If the rear corner radar is blocked or obstructed, or if the rear bumper around the rear corner radar or sensor is covered with foreign material such as snow, rain, or mud, or when a trailer or towing hitch is installed, detection performance may decrease, and Rear Cross-Traffic Collision-Avoidance Assist may be temporarily limited or disabled.

The rear cross-traffic safety system is not functioning properly. The "Radar Blocked" warning message may appear on the instrument cluster.

The system operates normally when such foreign material, trailer, or carrier is removed and the engine is restarted.

If the system does not operate normally after anything covering or blocking the sensors is removed, have the vehicle inspected by an authorized HYUNDAI dealer.
