Hyundai Tucson: Blind-Spot Collision Warning (BCW) / Blind-Spot Collision Warning Operation

Vehicle detection

When a vehicle is detected in a blind spot, the warning light on the side view mirror illuminates.

  • Blind-Spot Collision Warning operates when your vehicle speed is above 12 mph (20 km/h) and the speed of the vehicle in the blind spot area is above 7 mph (10 km/h).

Collision warning

Collision warning may operate when the turn signal is turned on in the direction of a detected vehicle.

  • To warn you of a potential collision, the warning light on the side view mirror may blink and an audible warning may sound.
  • When the turn signal is turned off or you move away from the vehicle in the blind spot, the function returns to vehicle detection state.


  • The detection range of the rear corner radar is determined by a standard road width. On narrow roads, the function may detect other vehicles in the next lane and warn you. On wide roads, the function may not be able to detect a vehicle driving in the next lane and may not warn you.
  • When the hazard warning flasher is on, the collision warning initiated by activating the turn signal may not operate.


Blind-Spot Collision Warning may not operate in all situations.

To prevent serious injury or death:

  • Only change the settings after parking your vehicle at a safe location.
  • When other system’s warning message appears or audible warning is heard, Blind-Spot Collision Warning may not warn you.
  • You may not hear the audible warning of Blind-Spot Collision Warning if the surrounding environment is too noisy.
  • Control your vehicle at all times. Always maintain a safe distance from the vehicles ahead and adjust your vehicle speed depending on the road conditions.
  • Never attempt to activate Blind-Spot Collision Warning by intentionally driving toward people, animals, objects, or other vehicles.


The images and colors in the instrument cluster may differ depending on the cluster type or theme selected from the settings menu.
