Check that there is the un-match display in any camera.
Is the un-match display visible?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK THAT AROUND VIEW MONITOR CONTROL UNIT IS REPLACED
Check that the around view monitor control unit is replaced.
Is the around view monitor control unit replaced?
YES >> GO TO 3.
NO >> GO TO 5.
3.RELEASE UN-MATCH DISPLAY (PERFORM ONLY WHEN THE AROUND VIEW MONITOR CONTROL
UNIT IS REPLACED)
1. Select “Camera Cont.” of Confirmation/ Adjust ment mode, and then set to “Calibrating Camera Image”
mode.
2. Press the “ENTER” switch of the multifunction switch on each screen of “Rear Camera”, “Front Camera”, “Dr-Side Camera”\
,
“Pass-Side Camera”.
CAUTION:
 Do never operate the center dial and up/down/left/right
switches. Only press the “ENTER” switch.
 Never perform “Initialize Camera Image Calibration”.
3. Display the around view monitor screen, and check that there is
no malfunction such as a difference between each camera
image.
Is there a malfunction?
YES >> Calibration end
NO >> GO TO 1.
4.PERFORM SIMPLIFIED CONFIRMATION/ADJUSTM ENT BY “FINE TUNING OF BIRDS-EYE VIEW”
1. Put target line 1 on the ground beside each axle using packing tape, etc.
2. Put target lines 2 equal to the vehicle total length + approximately 1.0 m (39.3 in) from the vehicle side
(right and left) at approximately 30 cm (11.8 in) away from the vehicle (make the line as parallel with the
vehicle as possible)

3. Select “Camera Cont.” of Confirmation/ Adjustment mode, and then set to “Fine Tuning of Birds-Eye View”
mode.
4. Select left and right cameras by pressing the “CAM ERA” switch, and perform the following confirmation.
- Check that target line 1 is aligned with the marker on the screen. Overlap the line aligned to the marker
with the upper/lower switches if necessary.
- Check if there is a difference between target lines 2 between cameras. Adjust target lines 2 to be straight
lines by operating the center dial and left/right switches if necessary.
CAUTION:
 Never adjust the front camera and rear camer a. Only adjust the right and left cameras.
 Operate the center dial slowly because the ch anging of the screen takes approximately 1 sec-
ond.
Simplified target line adjustment method
5. Adjust left and right cameras. Check that the difference between target line 1 and the marker on the
screen, and between target lines 2 is solved.
NOTE:
 It can be initialized to the NISSAN factory default c ondition with “Initialize Camera Image Calibration” of
“Calibrating Camera Image”.
 The adjustment value is cancelled on this mode by performing “Initialize Camera Image Calibration”.
Is the difference corrected?
YES >> Finish the writing to around view monito r control unit by pressing “ENTER” switch.
NO >> GO TO 5.
5.PERFORM “CALIBRATING CAMERA IMAGE”
Preparation of target line
1. Hang a string with a weight as shown in the figure. Put the points FM0, RM0 (mark) on the ground at the
center of the vehicle front end and rear end with white packing tape or a pen.
2. Route the vinyl string under the vehicle, and then pull and fix it on the point approximately 1.0 m (39.9 in)
to the front and rear of the vehicle through the points FM0 and RM0 using packing tape.

Perform “Calibrating Camera Image”
1. Select “Camera Cont.” of “Confirmation/ Adjustment” mode, and then set to “Calibrating Camera Image”
mode.
2. Overlap the target lines drawn on the ground with the calibration
marker on the screen by operating the center dial and upper/
lower/left/right switches of multifunction switch on each screen
of “Rear Camera”, “Pass-Side Camera”, “Front Camera”, “Dr-
Side Camera”.
3. “Writing...” is displayed by pressing the “ENTER” s witch, and then the adjustment result is written to the
around view monitor control unit.
CAUTION:
Check that “Writing...” is displayed . Do never perform other operations while “Writing...” is dis-
played.
>> GO TO 6.
6.PERFORM “FINE TUNING OF BIRDS-EYE VIEW”
This mode is designed to align the boundary between each camera image that could not be aligned in the
“Calibrating Camera Image” mode.
1. Select “Camera Cont.” of “Confirmation/ Adjustm ent” mode, and then set to “Fine Tuning of Birds-Eye
View” mode.
2. Operate the center dial and upper/l ower/left/right switch to over-
lap the marker on the screen and the target lines on the ground.
NOTE:
Move the “+”- mark on the camera position to adjustment by
pressing the “CAMERA” switch.
3. When the target line is overlapped on the marker, press the “ENTER” switch to write the adjustment result to the around
view monitor control unit.
CAUTION:
Check that “Writing...” is disp layed. Do never perform other
operations while “Writing...” is displayed.
