Climate Automatic recirculated-air control AUC/Recirculated-air mode Switch on the desired operating mode by pressing this button repeatedly: > LED off: outside air flows in continuously. > Left-hand LED on, AUC mode: a sensor detects pollutants in the outside air. If necessary, the system blocks the supply of outside air and recirculates the inside air. As soon as the concentration of pollutants in the outside air has decreased sufficiently, the system automatically switches back to outside air supply. > Right-hand LED on, recirculated-air mode: the supply of outside air is permanently shut off. The system then recirculates the air currently within the vehicle. If condensation starts to form on the inside window surfaces during operation in the recirculated-air mode, you should switch it off while also increasing the air flow rate as required. The recirculated-air mode should not be used continuously for lengthy periods, otherwise the quality of the air inside the car will gradually deteriorate.< > At an outside temperature below 77 7/ 25 6 The LED is lit when the function is on. As of radio readiness, you can set the interior temperature, the air flow rate and the air distribution. Defrosting windows and removing condensation Quickly removes ice and condensation from the windshield and front side windows. Switch on the cooling function as well. Switching cooling function on/off The cooling function cools and dehumidifies the incoming air before reheating it as required, according to the temperature setting. This function is only available while the engine is running. The cooling function helps prevent condensation on the windows or removes it quickly. Depending on the weather, the windshield may fog over briefly when the engine is started. The cooling function is automatically switched on along with the AUTO program. Via the button on the steering wheel You can switch quickly between the recirculated-air mode and the previous mode using a button on the steering wheel, refer to page 11. Rear window defroster The defroster is switched off automatically after a certain time. Depending on your vehicle's equipment, the upper wires serve as an antenna and are not part of the rear window defroster. Residual heat The heat stored in the engine is used to heat the passenger compartment, e.g. while stopped at a school to pick up a child. The function can be switched on when the following conditions are met: > Up to 15 minutes after the engine has been switched off > While the engine is at operating temperature > As long as battery voltage is sufficient 82 Online Edition for Part no. 01 41 0 014 960 - © 02/08 BMW AG

Automatic recirculated-air control
AUC/Recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
>
LED off: outside air flows in continuously.
>
Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently,
the system automatically switches back to
outside air supply.
>
Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air flow rate as
required.
The recirculated-air mode should not be used
continuously for lengthy periods, otherwise the
quality of the air inside the car will gradually
deteriorate.

Via the button on the steering wheel
You can switch quickly between the recircu-
lated-air mode and the previous mode using a
button
on the steering wheel, refer to page

.
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>
Up to 15 minutes after the engine has been
switched off
>
While the engine is at operating tempera-
ture
>
As long as battery voltage is sufficient
>
At an outside temperature below 77

bution.
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
