(A) Check Driver Assistance system

If the sophisticated Rear Cross-Traffic Collision-Avoidance Assist system on your Kia Sorento encounters an operational fault or fails to function correctly, the Master warning light (Kia Sorento master warning icon indicator) illuminates directly on the digital instrument cluster, accompanied by a descriptive diagnostic warning message that remains visible for several seconds to grab your attention.

To ensure your safety systems remain fully operational, have the function thoroughly inspected by an authorized Kia service professional or dealer as soon as possible.

Similarly, when the outside rearview mirror warning indicator light experiences an internal fault or stops working properly, the Master warning light (Kia Sorento cluster master warning indicator icon) lights up on your Kia Sorento instrument cluster along with a corresponding alert message lasting for several seconds.

Promptly schedule an inspection of this warning indicator system at an authorized Kia dealership to maintain full situational awareness on the road.

(A) Driver Assistance system limited. Radar blocked.

When environmental debris, heavy mud, rain, or packed snow accumulates on the rear bumper directly over the rear-side radar sensors, or if you attach a heavy towing trailer or cargo carrier, sensor detection performance can degrade significantly, temporarily limiting or disabling the Rear Cross-Traffic Collision-Avoidance Assist on your Kia Sorento.

Should this interference occur, a dedicated notification warning message appears instantly on the instrument cluster to inform you of the restricted capability.

The safety system automatically resumes normal operation once you thoroughly clean away any foreign buildup like snow, ice, or rain from the sensor zone, or detach obstructive accessories from the rear bumper.

If your Kia Sorento safety features still refuse to operate correctly after you completely clear away all exterior obstructions, foreign materials, or weather residue, please visit an authorized Kia service center for a professional diagnostic evaluation.

WARNING

  • Even when a formal warning message fails to pop up on the instrument cluster display, the Rear Cross-Traffic Collision-Avoidance Assist on your Kia Sorento may occasionally experience reduced functionality or fail to operate properly.

  • The system might occasionally experience initialization delays or limited performance when operating in wide-open outdoor areas devoid of reflective structures immediately after you power ON your vehicle.

TIP

Always manually deactivate the Rear Cross-Traffic Collision-Avoidance Assist function through your settings menu prior to installing or removing a towing trailer, luggage carrier, or other rear attachments on your Kia Sorento, and remember to reactivate it once finished.
