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 as illustrated.
The radar sensors detect the approaching vehicle from up to approximately 66 ft (20 m) away.
If the radar detects a vehicle approaching from the side, the system gives visual and audible warning.
