(1) Check that the steering wheel is centered (approximately +/- 5 degrees or less) and then select "Steering Center Memorize".

HINT:

When performing removal and installation of the rear television camera assembly, steering angle setting is not required.

(2) After performing the steering center memorize operation, turn the steering wheel to the left and right lock positions and select "Max Steering Angle Memorize". The maximum steering angle is then stored and the screen changes to the "Back Camera Position Setting D (*)" screen.

HINT:

The "Next" does not respond until the system memorizes the steering center and maximum steering wheel angle.
It is also possible to start by initially turning the steering to the right side.
When "Max Steering Angle Memorize" is selected, a beep will sound to confirm that the adjustment values have been stored.
The adjustment values will not be stored unless "Max Steering Angle Memorize" is selected after turning the steering wheel from lock to lock.
When "Back" is selected, the screen changes to the "Signal Check" screen without storing any values.
Even if no DTCs are detected, selecting "Max Steering Angle Memorize" may not cause the adjustment values to be stored if the steering sensor is malfunctioning.
If selecting "Max Steering Angle Memorize" does not cause the adjustment value to be stored after performing the steering angle setting procedure, replace the steering sensor.

(d) Back Camera Position Setting

*a	Target Bar for Back Camera Position Setting

HINT:

When the luggage compartment door is open, the "You can not calibrate the camera when the door is open. Please close the door." message will be displayed and camera position setting will not be possible.
If the "You can not calibrate the camera when the door is open. Please close the door." message is displayed even when the luggage compartment door is closed, perform inspections according to Problem Symptoms Table (When adjusting the camera optical axis, "You can not calibrate the camera when the door is open. Please close the door." is displayed even after the luggage compartment door has been closed).

(1) Perform vertical and horizontal position adjustment.

Move the circle (A) left, right, up and down by selecting the buttons (C), (D), (E) and (F) so that the left end of Target Bar for Back Camera Position Setting is positioned within the center of the circle (A) (center of the inner red circle).

(2) Perform roll angle adjustment.

Rotate the bar (B) by selecting the buttons (G) or (H) so that the bar (B) becomes parallel to Target Bar for Back Camera Position Setting.

(3) Select "Next" on the "Back Camera Position Setting D (*)" 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.
If (A) and the target adjustment bar are not aligned even if the tires are aligned straight ahead, perform the back camera position setting operation.

(2) Select "OK" to return to the "Function Check/Setting I" 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.
