Hyundai Elantra (CN7): Blind-Spot Collision Warning (BCW) / Function malfunction and limitations

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. 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 warning Vehicle detection To warn the driver a vehicle is detected, the warning light on the outside rearview mirror will illuminate. The system will operate when your vehicle speed is above 12 mph (20 km/h) and the speed of the vehicle in the blind spot area is above 7 mph (10 km/h).

    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.
