OverviewControlsMaintenanceRepairsDataIndex
Air conditioner Temperature
The graduations on the dial
provide general reference
values for the interior temper-
ature. We recommend
+70 7/+22 6 as a comfortable
setting. When you start the vehicle, the
system adjusts the air to the selected
temperature as quickly as possible, and
then maintains that temperature
constantly.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation.
Air supply
You can adjust the air supply
through an infinitely-variable
range. The heating and venti-
lation become more and more
effective as the air supply settings are
increased. In the 0 setting, the blower
and climate control are switched off
and the outside air supply is blocked.
Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
Air conditioning
The air is cooled and dehu-
midified and Ñ depending on
the temperature setting Ñ warmed
again. Depending on the weather, the
windshield may fog over briefly when
the engine is started. You can reduce
condensation forming on the windows
by switching on the air conditioning.
During air conditioning condensa-
tion forms, which then exits under
the vehicle. Traces of condensed water
of this kind are thus normal.<
Recirculated-air mode
You can respond to unpleas-
ant odors outside the vehicle
by temporarily switching off the outside
air supply. The system then recirculates
the air currently within the vehicle.
If you have a steering wheel with multi-
function buttons with the button for the
recirculated-air mode, you can also use
this button to switch to the recirculated-
air mode, refer to page 23.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<

Maximum cooling
You will get maximum
cooling capacity using this
program if the engine is running and
the outside temperature is above
approx. +41 7/+5 6.
The temperature display 9 jumps to
+60 7/+16 6, the system switches
over to the recirculated-air mode, and
the air streams out of the ventilation grill
with the maximum air supply. That is
why you need to keep these open if you
select this program.
Automatic recirculated-air
control AUC
If there are unpleasant
odors or pollutants in the
outside air, you can temporarily block
the air supply from the outside. The
system then recirculates the air
currently within the vehicle. Press the
button repeatedly to run through the
following control sequence
>Indicator lamps off: outside air supply
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air
currently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right-hand indicator lamp on: the
outside air supply into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a steering wheel with multi-
function buttons with the button for
recirculated-air mode, refer to page 23,
you can also use this button to switch
between Off and the recirculated-air
mode or AUC and the recirculated-air
mode.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air 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.
