Kia Rio: Forward Collision-Avoidance Assist (FCA) system (Radar type) / Limitation of the system

Kia Rio 2017-2020 YB Owners Manual / Driving your vehicle / Forward Collision-Avoidance Assist (FCA) system (Radar type) / Limitation of the system

FCA system is designed to monitor the vehicle ahead through radar signals to warn the driver that a collision is imminent, and if necessary, apply emergency braking. In certain situations, the radar sensor may not be able to detect the vehicle ahead. In these cases, FCA system may not operate. The driver must pay careful attention in the following situations where FCA operation may be limited:

Detecting vehicles

The sensor may be limited when:

- Driving on a curve

FCA system performance may be limited while driving on a curve. FCA system may not recognize the vehicle in front even if in the same lane. It may produce the warning message and the warning alarm prematurely, or it may not produce the warning message or the warning alarm at all. When driving on a curve, exercise caution, maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

FCA system may recognize a vehicle in an adjacent lane when driving on a curved road. In this case, the system may apply the brake. Always pay attention to road and driving conditions while driving. If necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance. Also, when necessary, you may depress the accelerator pedal to prevent the system from unnecessarily decelerating your vehicle. Always check the traffic conditions around the vehicle.

- Driving on a slope

FCA system performance may be limited while driving upward or downward on a slope, and may not recognize a vehicle in front in the same lane. It may produce the warning message and the warning alarm prematurely, or it may not produce the warning message and the warning alarm at all.

When FCA system suddenly recognizes the vehicle in front while passing over a slope, you may experience sharp deceleration.

Always keep your eyes forward while driving upward or downward on a slope, and, if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

- Changing lanes

When a vehicle changes lanes in front of you, FCA system may not immediately detect the vehicle, especially if the vehicle changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

When driving in stop-and-go traffic, and a stopped vehicle in front of you merges out of the lane, FCA system may not immediately detect the new vehicle that is now in front of you. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

- Recognizing the vehicle

If the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance, additional special attention is required. FCA system may not be able to recognize the cargo extending from the vehicle. In these instances, you must maintain a safe braking distance from the rearmost object, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.

WARNING - Testing FCA system

The FCA system may not operate in certain situations. Therefore, never test the operation of the FCA system using a person or object, as doing so may cause severe injury or even death.

WARNING - FCA system and Towing

Cancel FCA system in the User Settings on the LCD display, before towing another vehicle. While towing, the brake application may adversely affect your vehicle safety.

✽ NOTICE

In some instances, FCA system may be canceled when subjected to electromagnetic interference.
