FUNCTION DESCRIPTION
- The Rear Cross Traffic Alert system can help alert the driver of approaching vehicles when the driver is backing out of a parking space.
- The RCTA system uses side radars installed near the rear bumper to detect approaching vehicles.
- The RCTA system operates at speeds below 5 MPH (8 km/h) whenever the vehicle is in reverse.
- The side radar can detect vehicles on either side of vehicle within the detection zone shown in the illustration.
- The radar sensors detect the approaching vehicle from up to approximately 20 m (66 ft) away.
- If the radar detects a vehicle approaching from the side, the system gives visual and audible warning.
- If the side radar detects an approaching vehicle from the side, the RCTA system sounds a beep (single beep), the Blind Spot Warning/Blind Spot Intervention indicator on the side of the approaching vehicle flashes.
REAR CROSS TRAFFIC ALERT SYSTEM OPERATION DESCRIPTION
- ADAS control unit enables Rear Cross Traffic Alert system.
- The ADAS control unit turns ON the RCTA system when the BSW system is turned ON by the integral switch.
- ADAS control unit starts the control as follows, based on a reverse gear signal and vehicle detection signal.
- Side radar detects a vehicle approaching, and transmits the vehicle detection signal to ADAS control unit via CAN communication.
Operation Condition of Rear Cross Traffic Alert System.
ADAS control unit performs the control when the following conditions are satisfied:
- BSW system: ON (Selected by integral switch)
- When the vehicle is moving in reverse at 5 MPH (8 km/h) or less.
