Clean the BSI Radar Units
When mud, dirt, wet snow, leaves, or other foreign material sticks to the side of the rear bumper, the BSI system stops control and indicates in the MID that the BSI radar units must be cleaned. It also turns on the BSI indicator at the same time, and stores the DTC(s).
When the obstruction or contamination is removed, the indicator in MID goes off and the BSI system automatically returns to ON.
