    *1 Approx. 10 m
    *2 Approx. 14 m

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

      2. Check the tire pressure and adjust it if necessary Click here.

        *3 Bolt A
        *a FR
        *b LH

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

        OK
        Level's air bubble is within the 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°).

          Adjustment
          Adjustment Direction Adjustment Procedure Adjustment Angle
          Vertical adjustment Upward direction: Turn bolt A to negative (-) side For 1 complete turn of screwdriver, sensor moves about 0.12°
          Downward direction: Turn bolt A to positive (+) side

      *1 Millimeter Wave Radar Sensor

      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.

        SST
        09870-60000   ( 09870-60010 )
        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. A01FIRGE01

      Place the reflector.


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

        *b Extend String Through Front Center Mark

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

      3. 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 GTS:


        1. Connect the GTS to the DLC3.

        2. Turn the engine switch on (IG).

        3. Turn the GTS 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".

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

          Tech Tips

          A buzzer will sound for 1 second.

        9. Follow the GTS display, and continue with the adjustment.

          Note


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

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

      2. Check the following items on the radar cruise divergence data screen.

        Note

        While using the GTS beam axis adjustment mode, the actual direction and angle of the radar sensor may be different from the GTS data. In such a case, the deviation is displayed on the multi-information display in the combination meter.


        1. Confirm that the distance value is approximately 5 m (16.4 ft.).

          Tech Tips


          • A value between 0.0 m (0.0 ft.) and 6.3 m (20.7 ft.) should be indicated.

          • If the distance is 0.0 m (0.0 ft.), the sensor cannot detect the target. Reconfirm that there is no metal in the specified area in front of the vehicle (refer to the Notice at the beginning of this adjustment procedure).

        2. Confirm that the left/right side value is between 0.0 m (0.0 ft.) and 6.3 m (20.7 ft.).

          Tech Tips

          If the distance is 0.0 m (0.0 ft.), the sensor cannot detect the target. Reconfirm that there is no metal in the specified area in front of the vehicle (refer to the Notice at the beginning of this adjustment procedure).

    6. 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 screwdriver to adjust bolt B until the divergence of the radar beam axis is 0°.

        *1 Bolt B

        Based on the measured divergence of the beam axis, turn and adjust bolt B for horizontal adjustment of the millimeter wave radar sensor using a screwdriver.

        Adjustment
        Adjustment Direction Adjustment Procedure Adjustment Angle
        Horizontal adjustment Right direction: Turn bolt B to positive (+) side. For 1 complete turn of screwdriver, sensor moves about 0.07°
        Left direction: Turn bolt B to negative (-) side.

        Tech Tips

        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. Select "Next". The driving learning value is automatically reset.

        Tech Tips

        A buzzer will sound for 10 seconds or more.

      4. Disconnect the GTS from the DLC3.

    7. Recheck and readjust the vertical direction of the radar sensor.
