Sunroof panel removal
1. Move sun visor to the back position.
2. Open sunroof in the slanted position.
3. Adjust the lower trim strip.
Loosen the front part of the lower trim strip in the direction
of car's interior to take the rear part off the hook.

Sunroof panel installation
The window panel must be installed at the initial position
(window panel is closed).
1. Window panel location
The mark (indicated by the arrow) on the top of rear guide

Insert six sheets of paper, each of about 0.3 mm thickness,
around the window panel to make sure that clearances
around the panel is symmetrical.
