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 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

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 distri-
bution.

Defrosting windows and removing

condensation

Quickly removes ice and conden-
sation 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 condensa-
tion 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.

Rear window defroster

The defroster is switched off auto-
matically 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.
