Automatic climate control
Comfortable interior climate
AUTO program7 offers the ideal air distribution
and air volume for almost all conditions, refer to
AUTO program below. All you need to do is
select an interior temperature which is comfort-
able for you.
The following sections inform you in detail
about how to adjust the settings.
Most settings are stored for the remote control
currently in use, refer also to Personal Profile
settings on page28.
Adjusting air distribution manually
The air distribution can be
switched on and off manually. The
air is directed to the windshield, to
the upper body area and to the
footwell.
The automatic air distribution can be switched
back on by pressing the AUTO button. The
cooling function is switched on automatically
and the manual air distribution setting is
cleared.
Temperature
Turn to set the desired tempera-
ture.
The automatic climate control
achieves this temperature as
quickly as possible regardless of the season,
using maximum cooling or heating power if nec-
essary, and then maintains it.
Avoid rapid switching between different tem-
perature settings. The automatic climate con-
trol will not have sufficient time to adjust the set
temperature.
Maximum heating power can be obtained with
the highest setting, regardless of the outside
temperature.
The system cools steadily in the lowest setting,
regardless of the outside temperature.
Maximum cooling
Press the button.
The system is set to the lowest
temperature, maximum air volume
and recirculated air mode.
Air flows out of the vent outlets for the upper
body region. Open them for this purpose.
Air is cooled as quickly as possible
>Above an outside temperature of approx.
327/06
>When the engine is running
AUTO program
Press the button.
Air volume, air distribution and
temperature are controlled auto-
matically.
Depending on the selected temperature, AUTO
intensity and outside influences, the air is
directed toward the windshield, the side win-
dows, the upper body and the footwell.
Pressing the AUTO button automatically
switches on the cooling function.
At the same time, a condensation sensor con-
trols the program so as to prevent window con-
densation as much as possible.
The program is switched off when the air distri-
bution is set manually or the button is pressed
again.
Intensity of the AUTO program
With the AUTO program switched on, auto-
matic control of the air volume and air distribu-
tion can be adjusted:
Press the left side of the button to
reduce the intensity. Press the
right side of the button to increase
it.
The selected intensity is shown on the display
of the automatic climate control.
Convertible Program
The Convertible Program is active when the
convertible top is open and the AUTO program
is switched on. During the Convertible Program,

the automatic climate control is optimized for
driving with the soft top down. In addition, the
air volume is increased as vehicle speed
increases.
The effectiveness of the Convertible Pro-
gram can be enhanced considerably by
installing the wind deflector.<
Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left side of the button to
reduce the air volume. Press the
right side of the button to increase
it.
The air flow rate is lowered or switched off
entirely to reduce the drain on the battery. The
display remains the same.
Automatic recirculated air control
AUC/Recirculated air mode
You can respond to unpleasant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
>Right-hand LED on, recirculated air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated air mode and increase the air
volume, if necessary. Make sure that air can
flow onto the windshield.
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 page11.
ALL program
Press the button.
The current temperature setting
on the driver's side is transferred to
the front passenger side.
If the temperature setting on the driver's side is
changed, the temperature on the front passen-
ger side is changed as well.
The program is switched off when the setting is
adjusted on the front passenger side or the but-
ton is pressed again.
Defrosting windows and removing
condensation
Press the button.
Quickly removes ice and conden-
sation from the windshield and
front side windows.
For this purpose, also switch on the cooling
function.
Switching cooling function on/off
The passenger compartment can only be
cooled while the engine is running.
Press the button.
The air is cooled and dehumidified
and – depending on the tempera-
ture setting – warmed again.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
Pressing the AUTO button automatically
switches on the cooling function.
Rear window defroster
Press the button.
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.
