Hyundai Tucson: Blind-Spot Collision-Avoidance Assist (BCA)

Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Owner's Manual / Driver assistance system / Blind-Spot Collision-Avoidance Assist (BCA)

Blind-Spot Collision-Avoidance Assist is designed to help detect and monitor approaching vehicles in the driver's blind spot area and warn the driver of a possible collision with a warning message and audible warning.

In addition, if there is a risk of collision when changing lanes or driving forward out of a parking space, Blind-Spot Collision-Avoidance Assist will help avoid a collision by applying the brake.

Blind-Spot Collision-Avoidance Assist

Blind-Spot Collision-Avoidance Assist helps detect and inform the driver that a vehicle is in the blind spot.

CAUTION

The detecting range may vary depending on the speed of your vehicle.

However, even if there is a vehicle in the blind spot area, Blind-Spot Collision- Avoidance Assist may not warn you when you pass by at high speeds.

Blind- Spot Safety System Operation

Warning and control

Vehicle detection

  • To warn the driver a vehicle is detected, the warning light on the side view mirror and head-up display (if equipped) will illuminate.
  • The system will operate 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 will operate when the turn signal is turned on in the direction of the detected vehicle.
  • If 'Warning Only' is selected from the Settings menu, the collision warning will operate when your vehicle approaches the lane the blind spot vehicle is detected.
  • To warn the driver of a collision, the warning light on the side view mirror and head-up display (if equipped) will blink. At the same time, an audible warning will sound.
  • When the turn signal is turned off or you move away from the lane, the collision warning will be canceled and the system will return to vehicle detection state.

WARNING

  • The detecting range of the rear corner radar is determined by a standard road width, therefore, on a narrow road, the system may detect other vehicles in the next next lane and warn you. In contrast, on a wide road, the system 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 by the turn signal will not operate.

Information

If the driver's seat is on the left side, the collision warning may occur when you turn left. Maintain a proper distance with the vehicles in the left lane. If the driver's seat is on the right side, the collision warning may occur when you turn right.

Maintain a proper distance with the vehicles in the right lane.

Collision-Avoidance Assist (while driving)

  • To warn the driver of a collision, the warning light on the side view mirror will blink and a warning message will appear on the cluster. At the same time, an audible warning will sound.
  • The system will operate when your vehicle speed is between 40~120 mph (60~200 km/h) and both lane markings of the driving lane are detected.
  • Emergency braking will be assisted to help prevent collision with the vehicle in the blind spot area.

WARNING

Collision-Avoidance Assist will be canceled under the following circumstances:

  • Your vehicle enters the next lane by a certain distance
  •  Your vehicle is away from the collision risk
  •  The steering wheel is sharply steered
  •  The brake pedal is depressed

After system operation or lane change, you must drive to the center of the lane. The system will not operate if the vehicle is not driven in the center of the lane.

Collision-Avoidance Assist (while departing)

  • To warn the driver of a collision, the warning light on the side view mirror will blink and a warning message will appear on the cluster. At the same time, an audible warning will sound.
  • The system will operate when your vehicle speed is below 2 mph (3 km/h) and the speed of the vehicle in the blind spot area is above 3 mph (5 km/h).
  • Emergency braking will be assisted to help prevent collision with the vehicle in the blind spot area.

  • When the vehicle is stopped due to emergency braking, the 'Drive carefully' warning message will appear on the cluster.

    For your safety, the driver should depress the brake pedal immediately and check the surroundings.

  • Brake control will end after the vehicle is stopped by emergency braking for approximately 2 seconds.

WARNING

Take the following precautions when using Blind-Spot Safety system:

  • For your safety, change the Settings after parking the vehicle at a safe location.
  • If any other system's warning message is displayed or audible warning is generated, Blind-Spot Safety system's warning message may not be displayed and audible warning may not be generated.
