BLIS camera Indicator light BLIS symbol The Blind Spot Information System (BLIS) is an information system that indicates the presence of another vehicle moving in the same direction as your vehicle in the sideview mirror's "blind area." CAUTION The BLIS system should only be repaired by a trained and qualified Volvo service technician. WARNING BLIS is an information system, NOT a warning or safety system. BLIS does not eliminate the need for you to visually confirm the conditions around you, and the need for you to turn your head and shoulders to make sure that you can safely change lanes. As the driver, you have full responsibility for changing lanes in a safe manner. The system is based on digital camera technology. The cameras are located beneath the side-view mirrors. When one (or both) of the cameras have detected a vehicle in the blind area (up to approximately 10 ft. (3 meters) from the side of your vehicle, and up to approximately 31 ft. (9.5 meters) behind the side-view mirror), see the illustration, the indicator light in the door panel illuminates. The light will glow continuously to alert the driver of the vehicle in the blind area. NOTE The door panel indicator light illuminates on the side of the vehicle where the system has detected another vehicle. If your vehicle is passed on both sides at the same time, both lights will illuminate. BLIS has an integrated function that alerts the driver if a fault should occur with the system. For example, if one or both of the system's cameras are obscured, a message (see the table on page 185) will appear in the information display in the instrument panel. If this occurs, clean the camera lenses. If necessary, the system can be temporarily switched off (for instructions, see page 185).
