If a malfunction occurs within the Reverse Parking Collision-Avoidance Assist (PCA) system or any of its integrated components, a descriptive warning message will appear on the Kia K4 instrument cluster. If the system fails to resume normal functionality after a restart, we strongly advise having your Kia K4 inspected by an authorized Kia dealer to ensure all safety features are fully operational.

The performance of the Reverse Parking Collision-Avoidance Assist relies heavily on the accuracy of the wide-rear view camera and the rear ultrasonic sensors of the Kia K4. If these components are obstructed by environmental factors—such as accumulated snow, heavy rain, mud, or other foreign materials—the system may be temporarily limited or completely deactivated for safety reasons. You can identify which specific sensor is affected by reviewing the "Service Message" section located in the utility information view of your Kia K4 instrument cluster.

In most cases, the system will automatically return to its normal functional state once you carefully remove any contaminants from the camera lens and sensor surfaces. It is crucial to keep these detection points clean at all times. If the function continues to display errors after the sensors and camera are thoroughly cleaned, please contact an authorized Kia dealer to have your Kia K4 inspected by a certified technician.

TIP

You can monitor the real-time status of your Kia K4 Reverse Parking Collision-Avoidance Assist by checking the dedicated service messages within the utility information view of the instrument cluster display.
