Blind-Spot Collision-Avoidance Assist malfunction and limitations

Blind-Spot Collision-Avoidance Assist malfunction

A: Check Driver Assistance system.

When Blind-Spot Collision-Avoidance Assist is not working properly, a warning message will appear on the cluster for several seconds, and the Master warning light () will appear on the cluster.

If this occurs, have Avoidance Assist inspected by an authorized Kia dealer.

A: Check side-view mirror warning light

When the outside rear-view mirror warning light is not working properly, a warning message will appear on the cluster for several seconds, and the Master warning light () will appear on the cluster. If this occurs, have Blind Spot Collision Avoidance Assist inspected by an authorized Kia dealer.

Blind-Spot Collision-Avoidance Assist disabled

A: Driver Assistance system limited. Radar blocked.

Covering the rear bumper around the rear corner radar or sensor with foreign materials, such as snow or rain, or installing a trailer or carrier can reduce the detecting performance, resulting in Blind-Spot Collision-Avoidance Assist temporarily limited or disabled.

A warning message and the Master warning light () are displayed on the cluster display, but it does not indicate a malfunction of Blind-Spot Collision-Avoidance Assist.

Blind-Spot Collision-Avoidance Assist will operate properly when such foreign material or trailer, etc., is removed, and then the vehicle is restarted.

If Blind-Spot Collision-Avoidance Assist does not operate properly after it is removed, have Blind Spot Collision Avoidance Assist inspected by an authorized Kia dealer.

WARNING
  • Even though the warning message does not appear on the cluster, Blind-Spot Collision-Avoidance Assist may not properly operate.

  • Blind-Spot Collision-Avoidance Assist may not properly operate in an area (for example, open terrain) where any objects are not detected right after the vehicle is turned on, or when the detecting sensor is blocked with foreign material right after the vehicle is turned on.

CAUTION

Turn off Blind-Spot Collision-Avoidance Assist to install or remove a trailer, carrier, or another attachment. Turn on Blind-Spot Collision-Avoidance Assist when finished.

NOTICE

You can check it in the service message of the utility information view of the cluster display window.
