driver’s side( Y page 153)Notes on climate control system
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the retractable
hardtop closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode ( Y page 150) is
deactivated.
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.XKeep the air intake grille in front of the
windshield free of snow and debris.
When the retractable hardtop is closed, do
not obstruct air flow by placing objects on the
air flow-through exhaust slots below the rear
window.
i If the vehicle interior is hot, ventilate the
interior before driving off. The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
system
GWarning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time when the
retractable hardtop is closed. Otherwise the
windows could fog up, impairing visibility and
endangering you and others.

Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
Deactivating
It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.
XPress button Á.
The indicator lamp in the button goes out.
The cooling function switches off after a
short delay.Activating
Moist air can fog up the windows. You can
dehumidify the interior air with the air
conditioning.
XPress button Á.
The indicator lamp in the button comes on.
Automatic mode
Air distribution and air volume can be
adjusted automatically by the climate control
system. You can also adjust the settings for
air distribution and air volume manually.
When operating the climate control system in
automatic mode, the interior air temperature,
air volume and air distribution are adjusted
automatically.
In automatic mode, cooling with
dehumidification is switched on. This function
can be switched off if necessary.
GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

XOpening/closing: Turn thumbwheel =
upward or downward.
Ventilated glove box
The glove box can be ventilated, for instance
to cool its contents, when the climate control
system is activated. The level of airflow to the
glove box depends on the airflow and air
distribution settings. The temperature of the
air is approximately the same as that of the
air flowing from the center air vents.
! Close the glove box air vent when heating
the vehicle interior. Activate the air
conditioning (cooling function) when the
outside temperature is high. Otherwise,
temperature-sensitive items stored in the
glove box could be damaged.
iYou should keep air vent ; closed when
outside temperatures are low.
XOpening the air vent: Make sure air
vent ; is unobstructed.
XTurn thumbwheel : upwards.XClosing the air vent: Turn
thumbwheel : downwards.
AIRSCARF vent
GWarning!
When switching on the AIRSCARF neck-level
heating, the air streaming from the openings
may be very hot. When in close proximity to
the openings, you could be seriously burned.
To help avoid serious personal injuries, switch
the AIRSCARF to a lower heating level.
:AIRSCARF vent
You can switch on the AIRSCARF neck-level
heating with the AIRSCARF switch
