2016 Audi A6 / S6 — Owner's Manual
The sunshade can be opened and closed by hand when the roof is closed. The sunshade opens automatically when the roof is opened. You can still operate the sliding/tilting sunroof for about 10 minutes after the ignition is switched off. The switch is deactivated once the driver's or front passenger 's door is opened.
If the sunroof detects an object in its path when it is closing, it will open again automatically. In this case, you can close the roof with the power emergency closing function. If you let go of the switch early, the sunroof will open again. You can activate various systems such as garage doors, security systems and home lighting from inside your vehicle using the garage door opener (Homelink).
There are three buttons for this in the vehicle headliner that can be in used in place of up to three hand-held transmitters. To operate systems using the garage door opener, the three buttons in the roof headliner must be programmed first.
