SynchronisationSynchronisation  - Deluxe automatic air conditioner plus - basic settings - Heating and cooling - Controls - Audi S5 Owner's Manual - Audi S5

The air conditioner settings can be synchronised for all passengers.

When the synchronisation function is on, the driver's settings are also applied to the front passenger or vice versa. Any subsequent changes to the air conditioner settings (except for the seat heating*) are also applied to the other occupant.

You can still change the setting on the “synchronised” side (this will deactivate the synchronisation function).
