Automatic climate control
Cooling
Press this button. From ig-
nition key position 1 and
higher, the program switches to maxi-
mum cooling.
In ignition key position 0, pressing the
button activates the residual heat
mode. Refer to page 108.
Automatic recirculated-air control
(AUC)
You can respond to unpleasant
external odors by temporarily
stopping the flow of outside air. The
system then recirculates the air cur-
rently within the vehicle. Press the but-
ton repeatedly to run through the fol-
lowing control sequence:
> Indicator lamps off: Fresh air flows
into the vehicle
> Left-hand indicator lamp on – AUC
mode: The system detects pollutants
in the outside air and responds by
deactivating the outside air flow
when required. The system then re-
circulates the air currently within the
vehicle
> Right-hand indicator lamp on: The
flow of external air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.
If you have a multi-function steering
wheel with the AUC button (refer to
page 23), you can also switch between
"OFF" and AUC from there.
If the windows fog over in the re-
circulated-air mode, switch this
mode off and increase the air supply as
required.<
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
Temperature
You can make individual
temperature settings on the
driver's side and the front passenger
side. Your settings will be shown in the
display 7. The displayed temperatures
are reference values for the interior
temperature. We recommend 727
(226) as a comfortable setting,
whether the air conditioner is operating
or not. When you start the vehicle, the
system ensures that the selected tem-
perature is achieved as quickly as pos-
sible. It then maintains this tempera-
ture, regardless of the season.
You can set uncontrolled heater
output at up to 907 (326). Full
cooling output is available from the air
conditioner down to 607 (166).<
Air supply
The air flow is controlled
automatically in the "AUTO"
program. AUTO will appear in the dis-
play 7. Refer to the overview on
page 104. Use "+" and "–" to vary the
air flow. When your setting is displayed
by bars, the automatic air flow is
switched off. Automatic air distribution
maintains its setting. You can reactivate
the automatic air flow by pressing the
"AUTO" button.
When you press "–" during operation at
minimum blower speed, all displays are
canceled: The fan, heating and air con-
ditioner are switched off. The outside
air supply is closed. You can reactivate
the system by pressing any button of
the automatic climate control.
