The sunroof fitted to some models incorporates an outer glass and inner cover.

The control handle operates lock latches located at the rear of the sunroof. The handle also operates a vacuum seal system which holds and seals the sunroof in any desired position.

The vacuum seal is operated by engine vacuum. With the handle shut, the vacuum valve is closed and the seal exerts pressure under the periphery of the glass. When the handle is opened, the vacuum valve opens and causes the seal to collapse, enabling the glass to be moved.
