    *1 Approx. 10 m (32.8 ft.)
    *2 Approx. 14 m (45.9 ft.)

    CAUTION:

    Radiofrequency 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 pieces of metal 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 Click here.

      Check and adjust the vertical direction of the radar sensor.


      1. Remove dust, oil and foreign matter from the radar sensor level rack.

      2. Set a level on the radar sensor level rack.

        *c Bolt
        *d Vehicle Front
        *e Vehicle Left
        *f 0°

        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 screwdriver to adjust bolt A until the air bubble is within the red frame.

        Tech Tips


        • The adjustable range within the level's red frame is +/- 0.2°.

        • The target angle is +0.2° (upward angle of 0.2°).

      Adjust the reflector height.


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

        09870-60040

        Tech Tips

        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.

        Set one end of the 10 m (32.8 ft.) string on the vehicle rear center point. Run the string over the vehicle front center point to a position 5 m (16.4 ft.) beyond the vehicle front center point, as shown in the illustration. Mark the 5 m (16.4 ft.) position.

      4. Place the reflector (SST) at the marked position.

        Note

        Perform the operation as precisely as possible.

    5. Check the radar beam axis.


      1. When using the Techstream:


        1. Connect the Techstream to the DLC3.

        2. Turn the ignition switch on (IG).

        3. Turn the Techstream on and turn the cruise control main switch on.

        4. Select "Connect to Vehicle".

        5. Select each item on the display screen and proceed to the next screen.

        6. Under "System Selection Menu", select "Radar Cruise".

        7. Select "Utility" from the display screen.

        8. Select "Beam Axis Adjustment" and proceed to the next screen.

        9. Follow the Techstream display and continue with the adjustment.

          CAUTION:

          Do not come within 20 cm (7.87 in.) of the radar sensor.

          Note


          • Turn the cruise control main switch on before pressing "Next".

          • Make sure there is at least 20 cm (7.87 in.) between the millimeter wave radar sensor and any nearby individuals.

          • If "Error beam axis" is displayed on the screen, press the "Yes" button, and repeat again.

          • Check that there are no metal objects in the specified area in front of the vehicle (refer to the NOTICE at the beginning of this adjustment procedure).

      2. Press the "Exit" button to finish beam axis adjustment.

      3. Disconnect the Techstream from the DLC3.

    6. After adjusting the radar beam axis, return the vehicle to its original condition.


      1. Install the cool air intake duct seal Click here.

      2. If any heavy items were removed from the vehicle, return them (luggage, heavy objects, etc.).
