Hyundai Tucson: Rear Cross-Traffic Collision-Avoidance Assist (RCCA) / Rear Cross-Traffic Collision- Avoidance Assist Malfunction and Limitations

Rear Cross-Traffic Collision- Avoidance Assist malfunction

When the Rear Cross-Traffic Collision- Avoidance Assist is not working properly, the "Check Rear Cross-Traffic Safety system" warning message may appear, and the warning light may illuminate on the instrument cluster. Have the vehicle inspected by an authorized HYUNDAI dealer.

When the side view mirror warning light is not working properly, the "Check side view mirror warning light" warning message may appear, and the 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 covered, or when the rear bumper around the rear corner radar or sensor is covered by any foreign material, such as snow, rain, or dirt, or when a trailer or hitch mounted carrier is installed, the detecting performance may reduce and temporarily limit or disable Rear Cross- Traffic Collision-Avoidance Assist.

The "Rear Cross-Traffic Safety system disabled. Radar blocked" warning message may appear on the instrument cluster.

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

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

WARNING

• Rear Cross-Traffic Collision-Avoidance Assist may not operate properly even if there is no warning message or warning light on the instrument cluster.
• Rear Cross-Traffic Collision-Avoidance Assist may not operate properly in open areas where no objects are detected (e.g. empty parking lot) or when the detecting sensors are blocked right after turning on the engine.
• Always turn off Rear Cross-Traffic Collision-Avoidance Assist when towing a trailer or using a hitch mounted carrier.
