Hyundai Elantra: Rear Cross-Traffic Collision Warning (RCCW) / Function malfunction and limitations

Function malfunction

When Rear Cross-Traffic Safety system is not working properly, the ‘Check Rear Cross-Traffic Safety system(s)’ warning message will appear on the cluster, and the system will turn off automatically, or the system will be limited. We recommend that the system be inspected by an authorized HYUNDAI dealer.

When the outside rearview mirror warning light is not working properly, the ‘Check side view mirror warning light’ warning message will appear on the cluster. We recommend that the system be inspected by an authorized HYUNDAI dealer.

Function disabled

When the rear bumper around the rear corner radar or sensor is covered with foreign material, such as snow or rain, or installing a trailer or carrier, it can reduce the detecting performance and temporarily limit or disable Rear Cross- Traffic Safety system.

If this occurs, the ‘Rear Cross-Traffic Safety system disabled. Radar blocked’ warning message will appear on the cluster.

The system will operate normally when such foreign material or trailer, etc. is removed.

If the system does not operate normally after it is removed, we recommend that the system be inspected by an authorized HYUNDAI dealer.

  • Even though the warning message does not appear on the cluster, Rear Cross-Traffic Safety system may not operate properly.
