    *a Approx. 10 m (32.8 ft.)
    *b Approx. 14 m (45.9 ft.)
    WARNING:

    Radio frequency. radiation exposure information:

    • This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
    • This equipment should be kept with minimum distance of 20 cm (7.87 in.) between the radiator (antenna) and your body at all times during adjustment.
    • This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
    NOTE:
    • Perform measurements on a level surface.
    • Make sure that no large metal objects are within a 10 m (32.8 ft.) x 14 m (45.9 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.).
      3. Remove the cool air intake duct seal (Refer to PROCEDURE - Step 1 ).
    2. Check and adjust the vertical direction of the radar sensor.

        *b Air Bubble
        *c Bolt
        *d Vehicle Front
        *e Vehicle Left
        *f 0°

        OK

        Level's air bubble is within red frame.

        If the bubble is not within the red frame, use a screwdriver to adjust the bolt until the air bubble is within the red frame.

        HINT: 

        • The adjustable range within the level's red frame is +/- 0.2°.
        • The target angle is +0.2° (upward angle of 0.2°).

          Adjustment Direction Adjustment Procedure Adjustment Angle
          Upward Turn screwdriver to positive (+) side When screwdriver is turned once, adjustment changes by about 0.14°
          Downward Turn screwdriver to negative (-) side
    3. Adjust the reflector height.

      *1 Millimeter Wave Radar Sensor
      1. Adjust the reflector so that the center of SST (reflector) is the same height as the millimeter wave radar sensor.
        • SST: 09870-60000 
          1. 09870-60010
        • SST: 09870-60040 

        HINT: 

        Prepare a 10 m (32.8 ft.) string, a string with a sharp-pointed weight (plumb bob) and a 5 m (16.4 ft.) tape measure.

    4. Place the reflector.
      1. Hang the string (with weight) from the center of the vehicle rear emblem. Mark the vehicle rear center point on the ground.
