CAUTION:
Exposure to radio frequency emissions is hazardous to your health. It is hazardous to be within 20 cm (7.9 in.) of the device's radio frequency aperture.

NOTICE:
  1. This device complies with FCC radio frequency emission regulations.
  2. Perform measurements on a level surface.
  3. Make sure that no large pieces of metal are within a 10 m (32.81 ft.) x 14 m (45.93 ft.) area in front of the vehicle. If possible, the surrounding area should also be free of large metal objects.

  1. Before adjusting the radar beam axis, prepare the vehicle as follows.

    1. Check the tire pressure and adjust it if necessary.

    2. Remove all excess weight from the vehicle (luggage, heavy objects, etc.).

  1. w/ Air suspension:
    Adjust the vehicle's height to the standard height.

      3. B108717E02

    3. Check that the level's air bubble is within the red frame.

      OK:
      Level's air bubble is within red frame.
      If the bubble is not within the red frame, use a hexagon wrench to adjust screw A until the level's air bubble is within the red frame.

      HINT:
      1. The adjustable range within the red frame of the level is +- 0.2°.
      2. The target angle is +0.2° (upward angle of 0.2°).

    I041811E01

  1. Adjust the reflector height.

    1. Adjust the reflector so that the center of the SST reflector is the same height as the millimeter wave radar sensor.

      SST
      09870-60000  

      HINT:
      Prepare a 10 m (32.81 ft.) string, a string with a sharp-pointed weight (plumb bob), and a 5 m (16.41 ft.) tape measure.



    B108718E01

  1. Place the reflector.

    1. Hang the string (with weight) from the center of the vehicle rear's emblem. Mark the vehicle rear's center point on the ground. Repeat for the front of the vehicle.



      2. B108719E01

    2. Set one end of the 10 m (32.82 ft.) string on the vehicle rear's center point. Run the string over the vehicle front's center point to a position 5 m (16.41 ft.) beyond the vehicle front's center point, as shown in the illustration. Mark the 5 m (16.41 ft.) position.



    3. Using a tape measure, measure 12 mm (0.47 in.) to the left of the 5 m (16.41 ft.) position. Place the reflector at that position.

      NOTICE:
      Perform the operation as precisely as possible.



      B108720E01



    B111086E01

  1. Adjust the radar beam axis.

    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).



    3. Turn the intelligent tester main switch ON, and turn the cruise control main switch ON.


      B087889E05



      B087890E03



  1. Check and adjust the horizontal direction of the radar sensor.

    1. Check that the divergence of the radar beam axis is 0° .

      Standard:
      0° (Both right and left)
      If the axis is not as specified, use a hexagon wrench to adjust screw B until the divergence of the radar beam axis is 0°.



      2. B108721E01

    2. Based on the measured divergence of the beam axis, turn and adjust screw B for horizontal adjustment of the millimeter wave radar sensor using a hexagon wrench.

      Result:

      1. Right direction: Turn screw B to positive (+) side.
      2. Left direction: Turn screw B to negative (-) side.
      		Approx. 0.33° per turn

      HINT:
      1. If "LEFT SIDE: 1.0°" is displayed, the divergence is 1.0° in the left direction. Turn screw B approximately 3 turns to the negative (-) side.
      2. If the value does not change to 0°, it is possible that the sensor is aiming at something different. Reconfirm that there are no reflective materials in the surrounding area.



      3. B108722E01

    3. Reset the radar sensor's driving learning values. Prepare a type of metal that can block radio waves, such as aluminum foil. Cover the radar sensor's left half with the metal for 10 seconds.

      NOTICE:
      Be sure to keep the reflector in place and make sure that there is nothing between the sensor's left half and the reflector.
