Emergency moon roof operation
If, because of an electrical fault (e.g. a blown fuse) it is not possible to operate the moon roof
electrically, then it is possible to operate it manually.
First, using a Phillips-head screwdriver, remove the two screws that secure the moon roof motor cover to
the headliner. Then using a screwdriver, depress the white plastic clutch pin in the center of the motor
screw (see illustration) and turn the screw to close or to open the roof as desired.
