Work Procedure (Rear Vi ew Camera Calibration)INFOID:0000000009464744
CAUTION:
Perform the calibration under the sp ecified vehicle condition (fuel full, no-load, specified tire pressure,
etc.). Refer to DAS-107, "Work Procedure (Preparation)"
.
1.CHECK REAR VIEW CAMERA HEIGHT
Measure the rear view camera height “H”.
>> GO TO 2.
2.REAR VIEW CAMERA CALIBRATION
1. Select “Work Support” on “AVM” with CONSULT.
2. Select “REAR CAMERA ITS”.
3. Select "OK". CAUTION:
• Perform the calibration after the ignition or en gine has been kept on for at least 10 minutes to
stabilize camera.
• Operate CONSULT outside the vehicle, and close al l doors to retain appropriate vehicle altitude.
4. Input the rear view camera height "H", and then touch "APPLY".
5. Confirm that the same value is displayed on the center display.
6. Confirm the following items:
- The target should be accurately placed.
- The vehicle should be stopped.
- The vehicle should be under the specified vehicle condition.
7. Select “Start” to perform calibration.
8. Confirm the displayed item.
- “Completed”: Select “Completion”.
