Blind Spot Information System - Overview: BLIS®
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The BLIS® aids the driver in assessing whether another vehicle is present within a specific area (blind spot) to either side of the vehicle, extending rearward approximately 6 m (20 ft) beyond the rear bumper while driving on roads and highways. The system is not designed to prevent contact with other vehicles or objects. The BLIS® uses the exterior mirror BLIS® Light Emitting Diodes (LEDs) to alert the driver that a vehicle has been detected. The BLIS® provides alerts to the driver when the vehicle is in a forward gear and the vehicle speeds is greater than 10 km/h (6 mph).
