Blind Spot Warning (BSW) system/Blind Spot InterventionTM system (if so 
equipped)  - Starting and driving - Infiniti QX Owners Manual - Infiniti QX

The Blind Spot Warning (BSW) and Blind Spot InterventionTM systems can help alert the driver of other vehicles in adjacent lanes when changing lanes.

The BSW system uses radar sensors 1

The BSW system uses radar sensors 1 installed near the rear bumper to detect other vehicles beside your vehicle in an adjacent lane. In addition to the radar sensors, the Blind Spot InterventionTM system uses a camera2 installed behind the windshield to monitor the lane markers of your traveling lane.

The radar sensors can detect vehicles on

The radar sensors can detect vehicles on either side of your vehicle within the detection zone shown as illustrated. This detection zone starts from the outside mirror of your vehicle and extends approximately 10 ft (3.0 m) behind the rear bumper, and approximately 10 ft (3.0 m) sideways. The BSW system operates above approximately 20 MPH (32 km/h). If the radar sensors detect a vehicle in the detection zone, the BSW/Blind Spot InterventionTM indicator light illuminates. If the driver then activates the turn signal, a chime will sound twice and the BSW/Blind Spot InterventionTM indicator light will flash. The Blind Spot InterventionTM system operates above approximately 37 MPH (60 km/h). If the system detects a vehicle in the detection zone and your vehicle is approaching the lane marker, the Blind Spot InterventionTM system provides an audible warning (three times), flashes the BSW/Blind Spot InterventionTM indicator light and slightly applies the brakes for a short period of time on one side to help return the vehicle back to the traveling lane. The Blind Spot InterventionTM system provides an audible warning and turns on or flashes the BSW/Blind Spot InterventionTM indicator light even if the BSW system is off.

► The BSW and Blind Spot InterventionTM WARNING

► The BSW and Blind Spot InterventionTM systems are not a replacement for proper driving procedure and are not designed to prevent contact with vehicles or objects. When changing lanes, always use the side and rear mirrors and turn and look in the direction you will move to ensure it is safe to change lanes. Never rely solely on the BSW or Blind Spot InterventionTM system.
► Using the Blind Spot InterventionTM system under some road, lane marker or weather conditions could lead to improper system operation. Always rely on your own steering and braking operation to avoid accidents.
► The BSW and Blind Spot InterventionTM systems may not provide a warning or brake control for vehicles that pass through the detection zone quickly.
