Another new feature of the 2011 Ford Edge is BLIS, Blind Spot Information System. Ford has yet again come up with another way to keep drivers safe on the road. The reasoning behind BLIS is simple, alert drivers to unseen vehicles. If you see a light pop up on your side view mirror beware there is a vehicle near. The light indicates when a vehicle has entered your blind spot. According to Ford.com, the cross-traffic alert feature uses blind spot monitoring sensors to audibly and visually alert you to impending traffic while you are slowly backing out of a driveway/parking spot and another vehicle is approaching from either side.
