How blind spot warning works

Blind spot warning (BSW) systems use a combination of cameras, radar, or ultrasonic sensors mounted outside your vehicle. The detect vehicles that are next to or behind your car. The system provide a visual warning, usually on the side view mirror or the front A pillar. When drivers activate the turn signal, some BSW systems give an audible and/or tactile (shaking steering wheel, for example) alert to indicate that it’s unsafe to merge or change lanes.

Blind spot warning systems are available in two versions

Blind Spot Warning (BSW)

Visual signal when another vehicle enters the blind spots. Audible signal if the driver activates the lane change to turn signal.

Blind Spot Warning With Automatic Emergency Steering (BSW w/AES)

If the system detects a vehicle in the blind spot area and the turn signal is activated, the system automatically steers and/or brakes if the driver attempts a lane change into the blind spot area.
