Calibrating Camera Image
 Perform the calibration of camera image caused by the incorrect mounting position of each camera, etc. Always perform calibration
after performing the following work.
- When each camera or each camera mount (door mirror, front grille,
etc.) is removed
- When replacing around view monitor control unit
 When performing the calibration initialization, it can be set to the
NISSAN factory shipment condition.
Refer to AV-112, "
Work Procedure" for the calibration procedure.

CALIBRATING CAMERA IMAGE (AROUND VIEW MONITOR)
CALIBRATING CAMERA IMAGE (AROUND VIEW MONITOR)
DescriptionINFOID:0000000006216246
 Perform the calibration and perform the writing to the around view monitor control unit when removing and
replacing each camera, removing the camera mounting part s (front grille, door mirror, etc.) and replacing the
around view monitor control unit.
 Align the white lines on the road near the vehicle at the boundary of each camera image by this camera cal-
ibration. The white lines far from the vehicle may not be aligned at the boundary of each camera image. The
farther the line, the greater the difference is.
Work ProcedureINFOID:0000000006216915
Calibration flowchart
Following the flowchart shown in the figure, perform the calibration.
NOTE:
In the un-match display, the un-match camera position is indicated
as “ ” on the birds-eye view.
