BLIS
The BLIS function is designed to help provide assistance in heavy traffic with several lanes moving in the same direction by helping the driver to detect the presence of vehicles in the "blind spot" area behind and to the side of the vehicle.
Cross Traffic Alert
Cross Traffic Alert(CTA) is a supplementary driver support system to BLIS that is intended to help the driver detect vehicles crossing behind the vehicle while backing up. The auto-brake subfunction can help the driver stop the car if there is a risk of collision with an unobserved vehicle.
Cross Traffic Alert limitations
The Cross Traffic Alert (CTA) function with auto brake may have limited functionality in certain situations. Auto-brake is active at speeds under 15 km/h (9.3 mph).
