BLIS® with Trailer Tow (BTT)
The BLIS® with Trailer Tow is designed to aid the driver in detecting vehicles that may have entered the detection area zone (A). The detection area is on both sides of the vehicle and trailer, extending rearward from the exterior mirrors to the end of the trailer. When a trailer is attached with Blind Spot Trailer set up through the message center, the BLIS® with Trailer Tow becomes active when driving forward above 10 km/h (6 mph).
