- Turn the engine switch on (IG).
- If the sliding roof is opened, close it fully.
- Push the open switch of the slide switch or the up switch of the tilt switch on the personal light, making the sliding roof operation as follows:
Tilt up -> Approximately 1 second -> tilt down -> slide open -> slide close
- Sliding roof stops at the fully closed position.
- Finish the initialization.
- Check that the operation works normally with AUTO operation.
NOTE:If the following conditions occur while operating, initialization will fail.
- Engine 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).
