FUNCTION DESCRIPTION
  • The Rear Cross Traffic Alert (RCTA) 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 15 km/h (9.3 MPH) whenever the vehicle is in reverse.
  • The side radar can detect vehicles on either side of vehicle within the detection zone shown as illustrated.
  • 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 BSW indicator on the side of the approaching vehicle flashes.
 
 
OPERATION DESCRIPTION
  • Side radar enables RCTA system.
  • Side radar starts the control as follows, based on a reverse gear signal and vehicle detection signal.
  • Side radar detects a vehicle approaching.
 
 
OPERATION CONDITION
Side radar performs the control when the following conditions are satisfied:
  • RCTA system: ON
  • Vehicle speed: Approximately 15 km/h (9.3 MPH) or less
  • Selector lever: “R” position
 
 
CANCEL CONDITION
The side radar cancels the operation when the system is under any conditions of the operation cancellation condition.
  • When the system malfunction occurs.
  • When the area around the side radar is dirty.
