What does the SYNC button mean on the air conditioner?

More and more vehicles have automatic climate control and often a button labeled “Sync”. We explain what the button does and how useful the sync button is in everyday life!

More and more manufacturers are offering the “Sync” function for air conditioning. Its purpose is simple: With the Sync button, the temperature set on the driver’s side can be synchronized with that on the passenger’s side! If you have had a freezing passenger who has set the temperature to 25 degrees, you can quickly and easily transfer the 22 degrees from the driver’s side to the passenger’s side, for example.

Permanently adjust the temperature synchronously

But the real point is the permanent synchronization of the temperature: If you often drive alone, you can transfer the set temperature on the driver’s side to the other climate zone with the activated sync function. It will then be accepted automatically. If a passenger changes his temperature again, Sync is deactivated again.

Only for vehicles with automatic air conditioning

Tip: The sync function is only available for vehicles with at least two climate zones, i.e. cars with automatic climate control. Sometimes all three or four climate zones can be synchronized. Older Volkswagen models with automatic climate control without sync buttons also have a hidden sync function: Here you can synchronize the temperatures on the driver’s and passenger’s side by pressing and holding the “Auto” button!

In another article we already explained the function of the button with the snowflake / AC button. In addition, we have already explained in another article how best to set the air conditioning system when it is very hot. If you use the air conditioning, you should also keep the windows closed. Incidentally, the automatic air conditioning should always be operated in automatic mode if possible. This way the panes don’t fog up either!
