    3. Method 3 (Manual operation method)
      1. Turn the power switch ON (IG).
      2. Turn the clearance sonar main switch ON.
      3. Turn the steering wheel to the full left and right lock position.
        NOTE: Make sure to completely turn the steering wheel to the left and right full lock position.
    4. Method 4 (Manual operation method)
      1. At an area with few turns and curves, and minimal traffic, drive at 20 km/h (12 mph) or more for 5 minutes or more.
  19. RESET (INITIALIZE) POWER WINDOW REGULATOR MOTOR 
    NOTE: Resetting the power window regulator motor (initializing the pulse sensor) is necessary if: 1) the battery terminal cable is disconnected; 2) the power window regulator master switch, wire harness, power window regulator switch, window regulator, and power window regulator motor are replaced or removed / installed; 3) the D/C CUT or MPX-B fuses are replaced. If resetting is not performed, the multiplex network (master) switch will not be able to operate the AUTO operation function and jam protection function; and the multiplex network master switch will not be able to operate the remote UP / DOWN function.
    1. Turn the power switch ON (IG).
    2. Open the power window halfway by pressing the power window switch.
    3. Fully pull the switch up until the power window is fully closed and continue to hold the switch for at least 1 second.
    4. Check that the AUTO UP / DOWN function operates normally.

      HINT:

      If the AUTO UP / DOWN function operates normally, reset operations are completed. If abnormal, perform the following 3 steps.

    5. Disconnect the cable from the negative (-) battery terminal for 10 seconds or more.
      CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
    6. Reconnect the cable.
    7. Perform initialization from the first 4 steps again.

      HINT:

      If a condition where an initialization is necessary occurs (see 1), 2) and 3) above), the initialization procedures above are performed, but the remote UP / DOWN function does not operate, the power window regulator master switch may have a malfunction.

  20. RESET SLIDING ROOF DRIVE GEAR 
    NOTE: When disconnecting the cable from the negative (-) battery terminal, or disconnecting the sliding roof drive gear or connector, the sliding roof drive gear requires initialization of the pulse sensor. If a reset is not executed, the following functions do not operate: auto operation, jam protection function, key off operation, key-linked open and close, and transmitter-linked open and close.
    1. Turn the power switch ON (IG).
    2. If the sliding roof is opened, close it fully.
    3. Push the SLIDE CLOSE switch or TILT UP switch, making the sliding roof operation as follows:

      Tilt up → Approximately 1 second → tilt down → slide open → slide close

    4. Sliding roof stops at the fully closed position.
    5. Finish the initialization.
    6. Check that the operation works normally with AUTO operation.
      NOTE: If the following conditions occur while operating, initialization will fail.
      • Power switch is turned OFF.
      • Pushed switch is released while sliding roof is operating.
      • Vehicle speed is 5 km/h (3 mph) or higher.
      • Battery of sliding roof ECU is 1 V or higher.
      • Communication is cut off.

      HINT:

      • If the sliding roof cannot fully close or its position has become misaligned, perform the initialization again.
      • If the sliding roof TILT UP switch or SLIDE CLOSE switch is pressed and held until the roof glass has either stopped moving or started moving in the opposite direction, and then the switch is held for another 10 seconds or more, perform the initialization again.
      • If the AUTO operation function and jam protection function do not operate after the drive gear has been reset, replace the sliding roof drive gear (sliding roof ECU).
