PROCEDURE
1. SECURE APPROPRIATE AREA FOR PERFORMING LEARNING
(a) Park the vehicle on a level surface. HINT:
|
|
(b) Check the levelness of the ground.
(1) Check the levelness of the ground at the 2 points shown in the illustration.
Levelness Check Point |
(2) Place the level on each levelness check point and check that the air bubble of the level is centered.
(c) Adjust the tire inflation pressure to the specified pressure.

(d) Clean the windshield glass.
2. CREATE TARGET
NOTICE:
Do not laminate the target or attach reflective materials, such as clear adhesive tape, to its surface. If there are reflective areas on the surface of the target, they will appear white to the forward recognition camera and the target may not be recognized.
*a | Actual Target | *b | Target as Seen by forward recognition camera |
Reflective Object or Surface | - | - |
(a) Print 3 copies of the illustration.
(b) Check that the dimensions are within the values shown in the illustration.
*a | 12 mm (0.472 in.) | *b | 60 mm (2.36 in.) |
*c | 120 mm (4.72 in.) | *d | Blurry |
*e | Distorted | - | - |
NOTICE:
HINT:
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.
(c) Prepare a piece of cardboard and draw lines on it as shown in the illustration.
*a | Cardboard | *b | 130 mm (5.12 in.) or more |
*c | 730 mm (2.39 ft.) or more | *d | 297 mm (11.69 in.) |
*e | 65 mm (2.56 in.) or more | *f | 90° |
(d) Place the 3 target sheets on the cardboard with the black area of each at the top right and align the borders of the black and white areas with the lines as shown in the illustration.
*a | Border of Black and White Area | *b | Line |
(e) Securely attach the target sheets to the cardboard using double-sided tape.
*a | Border of Black and White Area | *b | 297 mm (11.69 in.) +/- 3 mm (0.12 in.) |
NOTICE:
Do not attach reflective materials, such as clear adhesive tape, to the target sheet surface as this may affect target recognition.
(f) Remove SST (reflector) from SST (base stand).
SST: 09870-60000
09870-60010
09870-60020
(g) Align the center of the target sheet with SST (reflector) and attach the target to SST (reflector) with double-sided tape.
(h) Install SST (reflector) to SST (base stand).
(i) 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. HINT:
|
|
(j) Move SST (reflector) up or down so that the center of the 3 target sheets is at the height shown in the illustration, and secure SST (reflector) in place. HINT: If the center of the target sheet is not within +/- 6 mm (0.24 in.) of the height specified, adjust the position of SST (reflector) so that the height is as specified. |
|
(k) 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.)
(1) When blocking the background by holding cardboard behind the target:
*a | Cardboard | *b | 1160 mm (3.80 ft.) or more |
*c | 560 mm (1.84 ft.) or more | *d | 580 mm (1.90 ft.) or more |
*e | 280 mm (0.918 ft.) or more | - | - |
HINT:
(2) When blocking the background using a light colored plain cloth:
*a | Light Colored Plain Cloth | *b | Whiteboard or Equivalent |
*c | 1160 mm (3.80 ft.) or more | *d | 560 mm (1.84 ft.) or more |
*e | 580 mm (1.90 ft.) or more | *f | 280 mm (0.918 ft.) or more |
HINT:
3. DETERMINE TARGET PLACEMENT POSITION
(a) 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 | *d | Bilateral Symmetry |
HINT:
Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.
(b) 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 | *d | Bilateral Symmetry |
HINT:
Lightly flick the string with your fingers several times to confirm that the string is perpendicular to the ground.
(c) Using tape and a string, create a line that connects point B to point A and extends at least 200 mm (7.87 in.) beyond the front center point of the vehicle (target position line).
*a | String | *b | Tape |
HINT:
