Spot the vehicles you might miss. Cross Traffic Alert is a part of the Blind Spot Information System (BLIS). It has been designed to warn you of vehicles that are approaching the rear of your vehicle from the side when your car is in reverse gear. When you are reversing out of a space and have limited visibility of the traffic around you, Cross Traffic Alert will sound a warning when detecting oncoming vehicles.
This technology will illuminate a light in the corresponding wing mirror (left or right depending on the direction of oncoming traffic), like the BLIS system, and a message will show in the information display. The system should never be used as a replacement for checking interior and exterior mirrors, this technology just enhances your safety to prevent collisions when reversing.
