Outer roof
The outer roof comprises two layers of fabric with a sealing layer in between. The sealing layer is used as a moisture barrier. Sewn along the sides is a drip molding to prevent water droplets falling onto the seats when the doors are opened.
The roof is folded over the edge of the first bow and is fastened with double-sided adhesive tape and riveted plastic rail. On the second, third and fourth bow, the roof is fastened with patches of fabric mounted with double-sided adhesive tape. This is kept in place by the plastic headlining rails, which are snap-fastened to the bows. The reinforcing bow is mounted between the third and fourth bows. It is not counted as one of the six main bows and is used only to support the outer roof and reinforce the two rear side frames.
Around the sixth bow, the fabric is folded over the edge with a sewn-on attaching profile, which is inserted into a groove and fastened with a sealing profile. The outer roof snaps into the rear rail with plastic fasteners sewn into the fabric. Along both sides of the outer roof run wires that maintain the shape and fit of the roof even at high speeds.
Between the outer roof and the headlining is a layer of insulating fleece material.
The electrically heated rear window is fitted with clips to a frame integrated in the outer roof.
