Automatic air distribution and supply

The AUTO program adjusts the
airflow and distribution patterns
for you while also using your

preselected temperature setting as the
basis for adjusting the interior climate to
adapt to external influences – summer,
winter.

The air conditioner comes on automatically
when you select the AUTO program.

Temperature adjustment

You can turn to select the
desired temperatures for the
driver's and passenger sides.
Your settings appear in the
Control Display's status line.

The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains
this temperature, regardless of the season.

Defrosting windows and removing
condensation

This program quickly removes
ice and condensation from the
windshield and door windows.

Adjusting air supply manually

You can adjust the air supply by
turning. The automatic air
supply control is operational
whenever you see your selec-
tion represented by a bar in the

Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic
air supply mode with the AUTO button.

Switching air conditioner mode on
and off manually

The air conditioner cools and
dehumidifies the incoming air
before also reheating it as

required, according to temperature setting.
Depending on the weather, the windshield

may fog over briefly when the engine is
started.

The air conditioner comes on automatically
when you select the AUTO program.

Maximum cooling

This program quickly provides
maximum cooling.

The temperature display reverts
to 607 (166) while the

system switches to the recirculated-air
mode and starts to provide maximum air
supply through the vent outlets only. For
this reason you should ensure that these
outlets are open before selecting this pro-
gram.

Outside air/AUC Automatic recircu-
lated-air control/Recirculated air

You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-

rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.

Press the button repeatedly to run through
the following control sequence:

Indicator lamps off: outside air flows
into the vehicle

Left-hand indicator lamp on – AUC
mode: the system detects pollutants
in the outside air and responds by
blocking the supply of outside air when
required. The system then recirculates
the air currently within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes

Right-hand indicator lamp on – recircu-
lated-air mode: the supply of outside air
into the vehicle is permanently blocked.
The system then recirculates the air
currently within the vehicle.

If condensation starts to form on the
inside window surfaces during opera-

tion in the recirculated-air mode, you
