What does sync mean on an Audi car?

[MilesRose]

Sync in the car refers to the synchronization button of the dual-zone automatic air conditioning. The relevant introduction about sync is as follows: Principle: It is achieved by controlling the left and right mixing air doors in different positions or the left and right hot water tanks. Pressing the sync button once makes the temperature of the air outlets on both sides of the car the same and synchronously adjusted; when the air conditioning is turned on, setting different temperatures on both sides will automatically turn off the sync. Features: Models with dual-zone automatic air conditioning can meet the different requirements of passengers in two different positions in the car for the air temperature inside the car. The independent temperature zones allow for free adjustment and conversion between different temperature differences.
