PROCEDURE

SECURING OF ADJUSTMENT ENVIRONMENT
1. *a 3 m (9.84 ft.)
  
  Park the vehicle on a level surface.
  Tech Tips
  - Make sure that the target recognition area of the forward recognition camera is free of objects which may be misrecognized as a target, such as overhead lights, windows, reflective objects, etc.
  - If there are any objects which may be misrecognized as a target behind the area where a target will be placed, prepare an appropriate object to block the background.
2. Check the levelness of the ground.
  1. *a 2.2 m (7.22 ft.)
    
    Levelness Check Point
    
    Check the levelness of the ground at the 3 points shown in the illustration.
  2. Place the level on each levelness check point and check that the air bubble of the level is centered.
3. Adjust the tire inflation pressure to the specified pressure.

4. Clean the windshield glass.

CREATE A TARGET

Print the illustration.

Check that the dimensions are within the values shown in the illustration.

*a	18 mm (0.709 in.)	*b	90 mm (3.54 in.)
*c	180 mm (7.09 in.)	*d	Blurry
*e	Distorted	-	-

Note

Make sure that the black areas of the target sheet are not glossy.
Make sure that the borders of the black and white areas on the target sheet are straight, and are not warped or blurry.

Tech Tips

If the dimensions of the created target sheet are not within +/- 5 mm (0.197 in.) of the specified values, adjust the printer settings and reprint the target sheet so that the dimensions are as specified.

Cut a piece of cardboard to be slightly larger than the target sheet.

*a	Target Sheet	*b	Cardboard
*c	180 mm (7.09 in.)	*d	190 mm (7.48 in.) or more
*e	95 mm (3.74 in.) or more	-	-

*A	Back of Target
*a	Target Sheet
*b	Cardboard

Prepare a piece of cardboard and draw lines on it as shown in the illustration.

Tech Tips

The lines on the back of the target can help with aligning the target with SST (reflector).

Place the target sheet on the cardboard with the black area at the top right as shown in the illustration, and securely attach the target sheet using double-sided tape.

Note

Do not attach reflective materials, such as clear adhesive tape, to the target sheet surface as this may affect target recognition.
Remove SST (reflector) from SST (base stand).

SST

09870-60000 ( 09870-60010, 09870-60020 )

Align the center of the target sheet with SST (reflector) and attach the target to SST (reflector) with double-sided tape.

*a	Mark-off Line	*b	Equal Distance to Center
	Reflective Surface	-	-

Apply masking tape to the reflective surface of SST (reflector) to cover it.
Install SST (reflector) to SST (base stand).

*a	String
*b	Weight
*c	Mark-off Line

Hang a weight with a pointed tip from the top center of the target sheet and align it with the mark-off line of SST (base stand) as shown in the illustration.

Tech Tips

Make sure that the points (A), (B) and (C) of the target sheet are aligned with the string.

*a 1350 mm (53.15 in.)

Move SST (reflector) up or down so that the center of the target sheet is at the height shown in the illustration, and secure SST (reflector) in place.

Tech Tips

If the center of the target sheet is not within +/- 6 mm (0.236 in.) of the height specified, adjust the position of SST (reflector) so that the height is as specified.

Prepare an object to block the area behind the target. (If there are any objects which may be misrecognized as a target behind the area where a target will be placed.)

When blocking out background by holding cardboard behind the target:

*a	Cardboard	*b	840 mm (33.07 in.) or more
*c	420 mm (16.54 in.) or more	-	-

Prepare a piece of cardboard with the dimensions shown in the illustration.
Tech Tips
- Do not use cardboard that is bent or has a pattern or image on it.
- Do not use cardboard which has a reflective surface or reflective objects attached to it.
- Make sure to hold the cardboard in such a way that fingers are not within the target recognition area.

When blocking the background using a light colored plain cloth:

*a	Light Colored Plain Cloth	*b	Whiteboard or Equivalent
*c	840 mm (33.07 in.) or more	*d	420 mm (16.54 in.) or more

Cover a whiteboard or equivalent with light colored plain cloth and secure it.
Tech Tips
- Make sure to stretch the cloth to remove wrinkles before securing it.
- Make sure that the target recognition area is free of clear adhesive tape, reflective surfaces and reflective objects.

TARGET PLACEMENT POSITION

Determine the target placement position.

*A	Target Placement Positions	-	-
*1	Placement Point 1	*2	Placement Point 2
*3	Placement Point 3	-	-
*a	forward recognition camera Position	*b	3000 mm (118.11 in.)
*c	550 mm (21.65 in.)	-	-

Hang a weight with a pointed tip from the center of the rear emblem, and mark the rear center point of the vehicle (point A) on the ground.

*a	String	*b	Weight
*c	Center	-	-

Tech Tips

Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.

Hang a weight with a pointed tip from the center of the front emblem, and mark the front center point of the vehicle (point B) on the ground (placement position).

*a	String	*b	Weight
*c	Center	-	-

Tech Tips

Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.

Using tape and a string, create a line that connects point B to point A and extends at least 2300 mm (7.54 ft.) beyond the front center point of the vehicle.

*a	String	*b	Tape
*c	481 mm (1.58 ft.)	*d	2151 mm (7.06 ft.)

Tech Tips

Make sure the string is taut when securing it with tape.
Lightly flick the string with your fingers several times to confirm that the string is aligned with point B.

Mark point C at a position 481 mm (1.58 ft.) in front of point B.
Mark point D at a position 2151 mm (7.06 ft.) in front of point B.
Using a string, mark line E at a position 1000 mm (3.28 ft.) from point C.
Using a string, mark line H at a position 1000 mm (3.28 ft.) from point C.
Using a string, mark line F at a position 1000 mm (3.28 ft.) from point D.
Using a string, mark line I at a position 1000 mm (3.28 ft.) from point D.
Mark point G (placement point 2) at the point where line E and line F intersect.
Mark point J (placement point 3) at the point where line H and line I intersect.

Using tape and a string, create a line that connects point G and point J (target position line).

*a	String	*b	Tape
*c	Target Position Line	-	-

Tech Tips

Make sure the string is taut when securing it with tape.
Lightly flick the string with your fingers several times to confirm that the string is aligned with points G and J.

Mark point K (placement position 1) at the point the string connecting points C and D and the string connecting points G and J intersect.
Confirm that the distance between points K and G (placement positions 1 and 2), and K and J (placement positions 1 and 3) is 550 mm (21.65 in.).

*a String *b 550 mm (21.65 in.)

Note

If the distance between either pair of points is not within +/- 3 mm (0.118 in.) of the specified value, start over from the marking of point A.
