CAUTION / NOTICE / HINT
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.
NOTICE:
-
Make sure to read "Before Starting Driving Adjustment" before proceeding with work.

- Make sure to perform the transition to online axis alignment mode with the vehicle stopped.
- Transitioning to online axis alignment mode will erase the learning value, so make sure to complete the adjustment.
- Turning the engine switch off while in online axis alignment mode will cause the system to exit online axis alignment mode, so to continue with the adjustment, it is necessary to transition to online axis alignment mode again (for Gasoline Model).
- Turning the power switch off while in online axis alignment mode will cause the system to exit online axis alignment mode, so to continue with the adjustment, it is necessary to transition to online axis alignment mode again. (for HV Model).
- All of the driving support system functions will be inoperative while the adjustment is in progress.
- When driving the vehicle with the Techstream connected, be careful with how the wires are routed.
- If the adjustment does not complete within a total cumulative time of 15 minutes when the vehicle is driven with all conditions met, perform the adjustment on another route.
- If the adjustment does not complete within a total cumulative time of 30 minutes when the vehicle is driven with all conditions met, perform the adjustment using target recognition.
- After adjustment is complete, to start the various systems it is necessary to turn the engine switch off and then to on (IG) again (for Gasoline Model).
- After adjustment is complete, to start the various systems it is necessary to turn the power switch off and then to on (IG) again. (for HV Model).
- In situations such as when the online axis alignment terminates abnormally, to perform online axis alignment again, turn the engine switch off and then back to on (IG) and enter online axis alignment mode again (for Gasoline Model).
- In situations such as when the online axis alignment terminates abnormally, to perform online axis alignment again, turn the power switch off and then back to on (IG) and enter online axis alignment mode again. (for HV Model).
PROCEDURE
1. PERFORM MILLIMETER WAVE RADAR SENSOR OPTICAL AXIS LEARNING (When driving with Techstream connected to vehicle)
(a) Adjust the tire pressures to the standard values.

(b) Make sure the surfaces of the radiator grille emblem and millimeter wave radar sensor assembly are clean and have no dirt, snow, or other matter adhering to them.
(c) Clean away any foreign matter adhering to the surface of the radiator grille emblem.
(d) Check that there is no damage or deformation around the front exterior area of the vehicle.
(e) Check that the radiator grille and front bumper assembly are securely installed, and that there is no damage or deformation around the installation areas. If any abnormalities are found, repair or replace parts as necessary.

(f) Check that the millimeter wave radar sensor assembly is securely installed and if any abnormalities are found, securely install the millimeter wave radar sensor assembly and then perform optical axis learning. |
|
(g) Check the levelness of the ground.
(1) Check the levelness of the ground at the 2 points shown in the illustration.
|
Levelness Check Point |
(2) Place the level on each levelness check point and check that the air bubble of the level is centered.
(h) Perform Front Radar Acceleration Sensor Calibration.
(1) With the engine switch off, connect the Techstream to the DLC3 (for Gasoline Model).
(2) Turn the engine switch on (IG) (for Gasoline Model).
(3) With the power switch off, connect the Techstream to the DLC3 (for HV Model).
(4) Turn the power switch on (IG) (for HV Model).
(5) Enter the following menus: Body Electrical / Front Radar Sensor / Utility / Front Radar Acceleration Sensor Calibration.
