RCCA malfunction and limitations
RCCA malfunction
When RCCA is not working properly, the warning message will appear for several seconds and the 
warning light will appear on the instrument cluster. Have your vehicle inspected by an authorized Kia dealer.
When the warning light on the side view mirror (outside mirror) is not working properly, the warning message will appear for
several seconds and the warning light will appear on the instrument cluster. Have the vehicle inspected by an authorized Kia dealer.
RCCA disabled
When the rear bumper around the rear corner 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 RCCA.
The warning message will appear on the instrument cluster. It is not a malfunction.
RCCA will operate properly when such foreign matters or trailer, etc. is removed.
Always keep the rear view camera and rear ultrasonic sensors clean.
If RCCA does not operate normally after it is removed, have your vehicle inspected by an authorized Kia dealer.
RCCA may not properly operate in an area (for example, open terrain), where any objects are not detected after turning ON the engine.
Even though the warning message does not appear on the instrument cluster, RCCA may not properly operate.
Turn off RCCA to install a trailer, carrier, etc., and remove the trailer, carrier, etc. to use RCCA.
