Use the same procedure for RHD and LHD vehicles.
The procedure listed below is for LHD vehicles.

INSTALL MILLIMETER WAVE RADAR SENSOR ASSEMBLY
1. Install the sensor with the 3 bolts in alphabetical order.
  
  Torque:
  
  5.5 N*m { 56 kgf*cm, 49 in.*lbf }
2. Connect the sensor connector.

ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY

Text in Illustration
*a	Approx. 10 m (32.8 ft.)
*b	Approx. 14 m (45.9 ft.)

CAUTION:

Exposure to radio frequency emissions is hazardous to your health. It is hazardous to be within 20 cm (7.87 in.) of the radio frequency aperture of the device.

Note

This device complies with FCC radio frequency emission regulations.
Perform adjustment 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.

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.).

Check and adjust the vertical direction of the radar sensor.

*b	FR

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 level's air bubble is within the red frame.

Tech Tips

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

Result

Adjustment Direction	Adjustment Procedure	Adjustment Angle (Reference)
Vertical adjustment	Upward direction: Turn bolt A to positive (+) side	For every rotation of screwdriver, sensor moves approximately 0.12 °
Vertical adjustment	Downward direction: Turn bolt A to negative (-) side

*1 Millimeter Wave Radar Sensor Assembly

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 string that is more than 10 m (32.8 ft.) long with a sharp-pointed weight (plumb bob), and a 5 m (16.4 ft.) tape measure.

*a	Adjust Center by Moving String to Right and Left
*b	Extend String Through Front Center Mark

Place the reflector.

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

Place the reflector (SST) at the marked position.

Note

Perform the operation as precisely as possible.

Check the radar beam axis.

Tech Tips

If a screen indicating an error is displayed while performing this procedure, perform the procedure again from *1.
1. Connect the intelligent tester to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the intelligent tester main switch on, and turn the cruise control main switch on.
4. Select "Auto" from the intelligent tester display screen.*1
5. Select "Radar Cruise" from the display screen.
6. Select "Utility" from the display screen.
7. Select "Beam Axis Adjustment" from the display screen.
8. Follow the tester display and select "Next".
  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.
    
    CAUTION:
    
    Do not come within 20 cm (7.87 in.) of the radar sensor.
9. Check the following items on the radar cruise divergence data screen.
  
  CAUTION:
  
  While using the beam axis adjustment mode of the intelligent tester, the actual direction and angle of the radar sensor may be different from the data on the intelligent tester. In such a case, the deviation is displayed on the multi-information display of the combination meter.
  1. Confirm that the distance is approximately 5 m (16.4 ft.).
    Tech Tips
    - A value between 0.0 and 6.3 m (20.7 ft.) is indicated.
    - If the distance is 0 m (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 and 6.3 m (20.7 ft.).
    
    Tech Tips
    
    If the distance is 0 m (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).

Check and adjust the horizontal direction of the radar sensor.

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°.

Standard
0° (Both right and left)

*1	Screwdriver Insertion Hole
*2	Bolt B

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

Result

Adjustment Direction	Adjustment Procedure	Adjustment Angle (Reference)
Horizontal adjustment	Right direction: Turn bolt B to positive (+) side	For every rotation of screwdriver, sensor moves approximately 0.07 °
Horizontal adjustment	Left direction: Turn bolt B to negative (-) side

Tech Tips

If "LEFT SIDE: 1.0°" is displayed, the divergence is 1.0° in the left direction. Turn bolt B approximately 14.8 turns to the negative (-) side.
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.

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

Tech Tips

A buzzer will sound for 10 seconds or more.
Disconnect the intelligent tester from the DLC3.

Recheck and readjust the vertical direction of the radar sensor.
