There are seven basic areas of operating space around the vehicle. The diagram on next slide shows the six zones, areas, or spaces surrounding the car which are visible to the driver. A zone is an area of space around a vehicle that is the width of a lane and extends as far as the driver can see. The vehicle occupies the central area, or Zone 7.
BLIS is designed to aid in detecting vehicles that may have entered the blind spot zone, which is represented by the vehicles in position A of the diagram below. The detection area is on both sides of your vehicle, extending rearward from the exterior mirrors to approximately 10 feet (3 meters) beyond the bumper. The system is designed to alert you if certain moving vehicles enter the blind spot zone while driving. WARNING.
