System malfunction and limitations
System malfunction

When Rear Cross-Traffic Safety system is not working properly, the 'Check Rear Cross-Traffic Safety system' warning message will appear on the cluster, and the system will turn off automatically or the system will be limited. We recommend that you have your vehicle inspected by an authorised Kia dealer/service partner.

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 you have your vehicle inspected by an authorised Kia dealer/service partner.
Sensor blocked

When the rear bumper around the rear-side radar or sensor is covered with foreign matters, 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. It is not a malfunction.
The system will operate normally when such foreign matters or trailer, etc. is removed.
Always keep the rear view camera and rear ultrasonic sensors clean.
If the system does not operate normally after it is removed, We recommend that you have your vehicle inspected by an authorised Kia dealer/service partner.
