NOTICE:

• Before starting this operation, make sure that the guide rails are not deformed and there is no foreign object on the guide rails.
• When the sliding roof glass is adjusted or removed/installed, or the sliding roof drive gear sub-assembly is replaced, the sliding roof drive gear sub-assembly must be initialized (pulse sensor initial position setting). Failure to perform initialization could result in displacement of the roof glass set position, defects in the automatic system or the roof glass moving in the reverse direction.
