Automatic recirculation

If the outside air is polluted, an air purity sensor in the vehicle will automatically switch on the air recirculation.

To prevent fumes, etc. in the outside air from entering the interior, we recommend that the automatic air recirculation should be switched on at all times.

If the air purity sensor in the air conditioner system detects a certain concentration of fumes in the outside air, the control unit will either pass the incoming air through the pollution filter or automatically switch on the air recirculation. If there is a high concentration of pollution in the outside air, the air conditioner automatically switches to air recirculation and cuts off the supply of air from the outside. As soon as the level of pollution decreases, air is fed into the vehicle from the outside again.

If the windows mist up when the automatic air recirculation is on, press the Audi A4: Deluxe automatic air conditioner plus - basic settings. The automatic air recirculation can switch itself off in certain conditions. button immediately.

The automatic air recirculation can switch itself off in certain conditions. If the outside temperature is less than about +10 ∞C, the automatic air recirculation will only operate for 30 seconds. If the air conditioner is switched to the ECON mode, or if the outside temperature is less than about -1 ∞C, the automatic air recirculation will only operate for 15 seconds.

Synchronisation

The air conditioner settings can be synchronised for all passengers.

When the synchronisation function is switched on, all subsequent air conditioner settings made on the driver's side (except for the seat heating*) are also applied to the front passenger's side.

The synchronisation is cancelled as soon as any adjustments are made on the front passenger's side.

Supplementary heater

Ц Set the Supplementary heater to auto or off.

Models with a diesel engine are equipped with a supplementary heater to help warm up the interior more quickly. At outside temperatures below about +5 ∞C the supplementary heater is switched on (and off) automatically when the engine is running, depending on the coolant temperature, the temperature in the vehicle interior and the temperature the heater is set to.
