Adjustment (One Time Recognition) [03/2017 - ]: Procedure

  1. SECURE APPROPRIATE AREA FOR PERFORMING LEARNING 
    1. Park the vehicle on a level surface.

      HINT: 

      • Make sure that the target recognition area of the pre-collision city sensor 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.

      *b 1 m (3.28 ft.)
    2. Check the levelness of the ground.
      1. Check the levelness of the ground at the 2 points shown in the illustration.

    3. Adjust the tire inflation pressure to the specified pressure.

      Refer to PROCEDURE - Step 1

    4. Clean the windshield glass.
  2. CREATE TARGET 
    NOTE:

    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 pre-collision city sensor and the target may not be recognized.

      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.

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

      Do not attach reflective materials, such as clear adhesive tape, to the target sheet surface as this may affect target recognition.

    6. Remove SST (reflector) from SST (base stand).
      • SST: 09870-60000 
        1. 09870-60010
        2. 09870-60020
    7. Align the center of the center target sheet with SST (reflector) and attach the target to SST (reflector) with double-sided tape.
    8. Install SST (reflector) to SST (base stand).
    9. Hang a weight with a pointed tip from the top center of the center target sheet and align it with the mark-off line of SST (base stand) as shown in the illustration.

      HINT: 

      • Make sure that the points (A), (B) and (C) of the target sheet are aligned with the string.
      • As SST may fall forward, make sure to place a weight on the base of SST.
    10. 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.

      HINT: 

      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.

    11. 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:

        *e 280 mm (0.918 ft.) or more - -
        1. Prepare a piece of cardboard with the dimensions shown in the illustration.

          HINT: 

          • 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.
      2. When blocking the background using a light colored plain cloth:

          HINT: 

          • 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.
  3. DETERMINE TARGET PLACEMENT POSITION
