Kia K4: Blind-Spot Collision-Avoidance Assist (BCA): / Limitations of Blind-Spot Collision-Avoidance Assist

Contents:

• This device complies with Part 15 of the FCC rules.

The Blind-Spot Collision-Avoidance Assist (BCA) system integrated into your Kia K4 is a sophisticated driver-assistance feature; however, it is subject to certain operational constraints. You may experience abnormal, unexpected, or limited performance under the following environmental and driving conditions:

• Adverse Weather: Heavy snowfall, torrential rain, or thick fog can obscure sensor visibility.

• Sensor Obstruction: The radar detection sensors are covered by mud, road grime, heavy snow, or other foreign materials.

• Extreme Temperatures: The ambient temperature surrounding the radar sensors is excessively high or low.

• Proximity Interference: Sensors are obstructed by nearby structures such as pillars, walls, or other passing vehicles.

• Complex Road Infrastructure: Driving on highway ramps, through tollgate facilities, or areas with dense metallic debris from construction.

• Fixed Object Interference: Driving near sound barriers, guardrails, tunnel walls, overhead signs, or street lights that may cause radar reflection issues.

• Roadside Vegetation: Driving on narrow roads where overgrown foliage contacts the vehicle.

• Open Environments: Driving in wide-open, featureless areas where the Kia K4 sensors lack sufficient reference objects.

• Wet Road Surfaces: Driving on surfaces that cause significant water spray or reflection.

• Traffic Dynamics: Situations where vehicles are passing at extremely high speeds, moving very close to your rear, or when you are actively changing lanes.

• Simultaneous Acceleration: When you and the vehicle in the adjacent lane accelerate at the same time.

• Complex Lane Maneuvers: When a vehicle in the next lane moves two lanes away, or a vehicle from two lanes away moves into the immediate adjacent lane.

• Aftermarket Attachments: Installation of trailers, bike carriers, or bumper stickers near the rear corner radar locations.

• Physical Damage/Misalignment: The front or rear bumper area is damaged, or the radar sensor module is physically out of its correct alignment.

• Vehicle Load/Geometry: Significant changes to vehicle height caused by heavy cargo, unevenly distributed weight, or incorrect tire pressure.

• Specific Object Detection: The system may have difficulty identifying specialized objects such as:

  • Motorcycles or bicycles.
  • Vehicles towing flat-bed trailers.
  • Large commercial vehicles like buses or semi-trucks.
  • Moving non-vehicular obstacles, including pedestrians, animals, shopping carts, or strollers.
  • Extremely low-profile vehicles, such as certain sports cars.

Furthermore, be aware that automatic braking control may be inhibited or limited under these conditions:

• Severe vehicle vibration (e.g., driving over deep potholes or extremely bumpy terrain).
• Driving on slippery surfaces such as ice, packed snow, or standing water.
• Low or improperly maintained tire pressure, or damaged tires.
• Unauthorized modifications to the original braking system of the Kia K4.
• Sudden, abrupt steering inputs by the driver.

WARNING

WARNING
