warning | Radio waves could adversely affect electric medical equipment. Those who use a pacemaker should contact the electric medical equipment manufacturer for the possible influences before use. |
caution | The system does not operate normally unless the radar alignment is performed. Always perform it. |

caution | If the radar alignment is adjusted with the target board in the incorrect position, the AEB/PFCW systems do not function normally. |
“A”–“E” (“C”–“F”) | : 2000 mm (78.7 in) |
note | Hang a string with a cone from the fender so as to pass through the center of wheel, and then mark a point at the center of the lateral surface of the wheel. |
note | Approximately 2 m (6.56 ft) or more from the front end of vehicle. |
note | Approximately 2 m (6.56 ft) or more from the front end of vehicle. |
caution | Make sure that “E” to “X” is equal to “F” to “X”. |
caution | For performing the radar alignment correctly, securely install (target board) to be parallel with the “E-F” line. |
L1 | : 2000 mm (78.7 in) |
L2 | : 0 mm (0 in) |
caution | Perform all necessary work for radar alignment until the adjustment completes as shown in the procedure. If the procedure does not complete, the AEB/MI-PILOT Assist/PFCW systems are inoperable. |
note | Confirm the following items;
|
caution | Never select “Start” when the target is not accurately placed. |
note | If the radar is in alignment at this time, “In progress” is displayed. It may take several 10s of seconds until the result is displayed. |

|
caution | Once “MILLIWAVE RADAR ADJUST” is started with M.U.T.-III SE, always continue the work until the horizontal radar alignment is completed successfully. If the job is stopped midway, the radar alignment is not adjusted and the AEB/MI-PILOT Assist/PFCW systems cannot operate. |

note | Tools 1–20–2721–1–IF, 1–20–2722–1–IF and J-50808 have been superseded and are no longer available, but may still be used for distance sensor alignment. |
note | Directional arrows and are shown to illustrate the direction of the laser assembly beams. |
caution | If the radar alignment is adjusted with the target board, wheel adapter, laser assembly, or rear stand in the incorrect position, the AEB/PFCW systems will not function properly or the alignment procedure may not be completed successfully. |
note |
note |
|
note | When the power switch is turned ON, the front laser signal will be emitted toward the front target board, and the rear laser signal will be emitted toward the rear of the vehicle. |
note |
|
note | Must be verify both horizontal and vertical adjustments anytime one adjustment is made. |
caution | If the radar alignment is adjusted with the target board in the incorrect position, the AEB/PFCW systems will not function properly or the alignment procedure may not be completed successfully. |
note | When adjusted properly, reflected laser beam must align with emitted laser beam and the two laser beams will be seen as one. |
