Subaru Legacy BN/BS (2015-2019) Owners Manual: Rear Cross Traffic Alert (RCTA)

1) Operating range

The system notifies the driver of another vehicle approaching from either side when driving in reverse. This feature helps the driver check the rear and side areas of the vehicle when moving backward.

If the system detects a vehicle approaching from either side while moving backward, it warns the driver of dangers in the following way.

•  The BSD/RCTA approach indicator light(s) on the outside mirror(s) flashes.
•  A warning buzzer sounds.
•  An icon appears on the rear view camera screen (if equipped)

Limitations of the detectability of RCTA

Since the detectability of RCTA is limited, the RCTA may not operate properly in parking areas in which the parking spaces are drawn diagonally to the driving lanes.

Example 1

1) The detection range of the radar sensors
2) Area out of detection range of the radar sensors
