Hyundai Elantra (CN7): Blind-Spot Collision Warning (BCW) / System 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 Blind-Spot Safety system.

If this occurs, the ‘Blind-Spot Safety system(s) disabled. Radar blocked’ warning message will appear on the cluster.

The system will operate normally when such foreign material or trailer, etc. is removed, and then the engine is restarted.

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, Blind- Spot Safety system may not properly operate.
  • Blind-Spot Safety system may not properly operate in an area (e.g. open terrain), where any substance are not detected right after the engine is turned on, or when the detecting sensor is blocked with foreign material right after the engine is turned on.

    Function malfunction When Blind-Spot Safety system is not working properly, the ‘Check Blind-Spot Safety system(s)’ warning message will appear on the cluster, and the system will turn off automatically, or the system will be limited.
