ClimateVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it alsodescribes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.

Direct the flow of air to the win‐
dows
, to the upper body area
, or to the knee area and foot‐
well
. Intermediate positions are
possible. In the 6 o'clock position, a
small amount of air is also directed toward the
windows to keep them from fogging over.
Recirculated air mode If the air outside the car has an un‐
pleasant odor or contains pollu‐
tants, shut off the supply to the interior of the car
temporarily. The system then recirculates the air
currently within the vehicle.
The recirculated air mode can also be activated/
deactivated, refer to page 12, via a button on the
steering wheel.
Only use recirculated air mode for a limited
period
If condensation starts to form on the inside win‐
dow surfaces during operation in the recircu‐
lated air mode, you should switch it off while also
increasing the air flow rate as required. The re‐
circulated air mode should not be used contin‐
uously for lengthy periods; otherwise, the qual‐
ity of the air inside the car will gradually
deteriorate.◀
Air volume Press the corresponding button.
The higher the rate, the more ef‐
fective the heating or cooling will
be.
The air flow rate may be reduced or the blower
may be switched off entirely to save on battery
power.
Switching the system on/off Press the left button at the mini‐
mum fan speed. The blower and air
conditioner are completely
switched off and the air supply is cut off.Seite 90ControlsClimate90
Online Edition for Part no. 01 40 2 609 184 - 09 11 500

To switch on the air conditioner, set the desired
air flow rate.
Switching cooling function on/off The cooling function cools and de‐
humidifies the incoming air before
reheating it as required, according to the tem‐
perature setting. This function is only available
while the engine is running.
The cooling function helps to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
Rear window defroster The defroster switches off auto‐
matically after a certain time or
when the hardtop is opened.

For almost all conditions, the AUTO program 7
offers the optimum air distribution and air flow
rate, refer to AUTO programs below. Select a
comfortable interior temperature only.
The following sections contain more detailed in‐
formation on the available setting options.
Most of these settings are stored for the remote
control currently in use, Personal Profile set‐
tings, refer to page 21.
Air distribution, manual
Depending on the selected setting, the air is di‐
rected to the windshield, to the upper body area,
to the knee area and into the footwell.
Adjusting air distribution manually Press the button repeatedly until
the air distribution is set as re‐
quired. The corresponding LED lights up.
The manual air distribution is also switched on
when the AUTO program is deactivated.Temperature
Set the desired temperatures indi‐
vidually for the driver's and passen‐
ger sides.
The automatic climate control ach‐
ieves this temperature as quickly as possible re‐
gardless of the season, using maximum cooling
or heating power if necessary, and then main‐
tains it.
To give the automatic climate control enough
time to achieve the set temperature, do not
switch between different temperature settings
in quick succession.
Maximum heating power can be obtained with
the highest setting, regardless of the external
temperature.
The lowest setting effects continuous cooling.Seite 92ControlsClimate92

Switching the cooling function on and
off
The cooling function cools and de‐
humidifies 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 to prevent conden‐
sation on the windows or to remove it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.
The cooling function is switched on automati‐
cally with the AUTO program.
Maximum cooling The air is cooled as quickly as pos‐
sible with the engine running.
The automatic climate control goes into recir‐
culated air mode at the lowest temperature. Air
flows at maximum rate from the vents for the
upper body area. You should therefore open the
vents for maximum cooling.
AUTO program
The AUTO program automatically adjusts the air
distribution to the windshield and side windows,
toward the upper body area, and into the foot‐
well and knee area.
The air flow rate and air distribution, in addition
to your temperature specifications, will be
adapted to outside influences as a result of sea‐
sonal changes, e.g., sunlight or window conden‐
sation.
The cooling function is switched on automati‐
cally with the AUTO program.
Switching on/off Press the button.Manual air distribution and air flow rate are acti‐
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the in‐
tensity when the AUTO program is switched on.
For example, air flow is adjusted automatically
to optimize climate control.
When the AUTO program is
switched on, the climate level of the
AUTO program can be selected us‐
ing the buttons for controlling the manual air
flow rate.
The selected climate level is displayed by an
LED.
Convertible program
When the hardtop is open, the convertible pro‐
gram is activated as well. In the convertible pro‐
gram, the automatic climate control is optimized
for driving with the hardtop open. In addition, the
air flow rate is increased as vehicle speed in‐
creases.
The effectiveness of the convertible program
can be enhanced considerably by installing the
wind deflector.
Adjusting air flow rate manually Press the left side of the button to
reduce air flow. Press the right side
of the button to increase it.
The air volume may be reduced automatically to
save battery power. The display remains the
same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the automatic
climate control. All displays are cleared except
for the rear window defroster if it is switched on.Seite 93ClimateControls93
