Nissan LEAF 2023 Owners Manual
9.12.4.2. RCTA system operation
The RCTA system can help alert the driver of an approaching vehicle when the driver is reversing out of a parking space.
When the shift position is in R (Reverse) and the vehicle speed is less than approximately 8 km/h (5 MPH), the RCTA system is operational.
If the radar detects an approaching vehicle from either side, the system chimes (once) and the side indicator light flashes on the side the vehicle is approaching from.
The RCTA system uses radar sensors (A) installed on both sides near the rear bumper to detect an approaching vehicle.
The radar sensors (A) can detect an approaching vehicle from up to approximately 20 m (66 ft) away.
