Side Distance Guideline CorrectionINFOID:0000000003533545
This mode is used to modify the side distance guidelines if they are dislocated from the rear view monitor
image, because of variations of body/camera mounting conditions.
SIDE DISTANCE GUIDELINE CORRECTION PROCEDURE
1. Create a correction line to modify the screen.
Draw lines on the rearward of the vehicle passing through the
following points: 200 mm (7.87 inch) from both sides of the vehi-
cle, and
• *1: 0.5 m (1.5 feet)
• *2: 1 m (3 feet)
• *3: 2 m (7 feet)
• *4: 3 m (10 feet)
and from the rear end of the bumper
2. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn igni-
tion switch ON. Touch “REARVIEW CAMERA” on “SELECT
SYSTEM” screen.
CAUTION:
Stop engine for safety when correcting side distance guide-
line.
