switch (A) to close it.
To express-open the sunroof, fully
press and release the rear of
switch (A) until the sunroof
reaches the desired position. To

The sunroof also has a sunshade

opened and closed manually.
If an object is in the path of the
sunroof while it is closing, the
anti-pinch feature will detect the
object and stop the sunroof.
