Emergency sun roof operation
If, because of an electrical fault (e.g. a blown fuse), it is not possible to operate the sun roof electrically,
then it is manually.
First, using a small screwdriver, remove the two screws that secure the sun 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 open the roof as desired.
