Buick Regal 2011 Owner's Manual page 45

The sunroof glass panel cannot be
opened or closed if the vehicle has
an electrical failure.
Dirt and debris may collect on
the sunroof seal or in the track.
This could cause an issue with
sunroof operation, noise, or
plugging within the water drainage
system. Periodically open the
sunroof and remove any obstacles
or loose debris. Wipe the sunroof
seal and roof sealing area using a
clean cloth, mild soap, and water.
Do not remove grease from the
sunroof.
Sunshade
The sunshade is manually operated.
Close or open the sunshade by
sliding. When the sunroof is
opened, the sunshade is
always open.
Safety Function
If the sunroof has any resistance
during automatic closing, it will
immediately stop and reverse.
To override the safety function,
press and hold the close sunroof
switch. The sunroof closes without
the safety function. To stop the
movement, release the switch.
Initializing the Sunroof
If the sunroof cannot be fully closed,
or the express open or close feature
does not function, the sunroof may
need to be initialized. This can
happen if the battery has been
disconnected or the sunroof has
been serviced.
