BLIS

Blind Spot Information System (BLIS)
BLIS, (the Blind Spot Information System) is particularly reassuring in congested and fast-moving traffic situations. Using rear-facing digital cameras installed in the door mirrors, it monitors the traffic on either side of the car. As a vehicle enters your blind spot, the system helps alert you with a discreet lamp built in to the front door post on the approaching side of the car. Together with the door mirrors, this helps enable you to quickly assess the feasibility of a lane change. The system is activated once the car exceeds 10 km/h, and reacts to almost any type of motor vehicle. It works equally well, day or night.
