* If the "Back door is open. Do not use the rear view monitor when the back door is not completely closed." message is displayed even when the luggage compartment door is closed, perform inspections according to Problem Symptoms Table (When adjusting the camera optical axis, "Back door is open. Do not use the rear view monitor when the back door is not completely closed." is displayed even after the luggage compartment door has been closed.) Guide Lines and Buttons are not Displayed for All Display Modes.

(1) Perform roll angle adjustment.

* Use switches A and B to rotate C so that it is parallel to the target adjustment bar.

(2) Perform vertical and horizontal position adjustment.

* Use the directional switches D, E, F and G to move C so that the target adjustment bar is centered in C.

(3) Select the "Next" button on the "Back Camera Position Setting" screen.

(e) Back Verify Mode





(1) Check that A and the target adjustment bar are overlapping.

* If the lines are not aligned, perform the "STEERING CENTER MEMORIZE" and "MAX STEERING ANGLE MEMORIZE" operations.

(2) Selecting "OK" will return to the "Service Menu" screen and complete the adjustment.

HINT
* The update is not completed until "OK" is selected.
* When "OK" is selected, a beep will sound to confirm that the adjustment values have been stored.
* The adjustment values are not stored until the beep has sounded.

(f) Finish diagnostic mode Audio And Visual System (with Intuitive Parking Assist System).

(g) Confirm steering angle adjustment.

HINT
If the steering angle has been adjusted, confirm the steering angle adjustment on the parking assist monitor screen after finishing diagnosis mode.

(1) Check on the parking assist screen that the predicted path line moves until the steering wheel is fully turned to either the left or right.

HINT
If the predicted path line stops moving before the steering wheel is fully turned to either the left or right, the steering angle adjustment values have not been stored correctly. In this case, perform "STEERING CENTER MEMORIZE" and "MAX STEERING ANGLE MEMORIZE" again.

3. BACK CAMERA POSITION SETTING (PROCEDURE 2)

HINT
Be sure to check for DTCs before performing this procedure Parking Assist Monitor System.

(a) Preparation for adjustment

(1) Park the vehicle with the steering wheel centered.

(2) Set a target bar behind the vehicle for optical axis adjustment of the rear television camera assembly (back camera position setting).

HINT
Create a target bar for adjustment only when adjusting the optical axis of the camera.
