If the turn signal is then activated, the system chimes (twice), the side BSW/RCTA indicator light flashes and the BSW indicator blinks (yellow) in the vehicle information display. The side BSW/ RCTA indicator light and the BSW indicator continue to flash until the detected vehicle leaves the detection zone.
