Put the car in reverse and than press the BCI switch, it will tell you if it on or off!
The sales guy at the dealership was telling me how they were testing the BCI by backing up into a trash can and the JX would stop inches before it hit it (except for one time).seems like the BCI image on the center console when in reverse suggests that it only works for traffic coming from the sides. If there is a non-moving object behind you, I don't think it will stop...am I wrong?
