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 0058.

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.

MAX COOL is only operational when the
engine is running.
If the air distribution controls as well as the
air volume control are set to \000Z and there
is a high need for cooling, MAX COOL is
activated. “MAX COOL” appears in
temperature controls \000n and \000s
(Y page 148).
This provides the fastest possible cooling of
the vehicle interior (when retractable hardtop
is closed).

Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e. g. before driving through
a tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
GWarning!
Fogged windows impair visibility,
endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should
clear interior window fogging. If interior
window fogging persists, make sure the air
conditioning is activated, or press button
\000f.
XActivating: Press button \000t.

Rafter 5 minutes if the air conditioning is
turned off
Rafter 30 minutes if the outside
temperature is above approximately
41‡ (5†)
Residual heat and ventilation
With the engine turned off, it is possible to
continue to heat or ventilate the interior for
up to 30 minutes. This feature makes use of
the residual heat produced by the engine.
iIf you switch on the residual heat function
when outside temperatures are high, only
the ventilation will be switched on.
iHow long the system will provide heating
depends on the coolant temperature and
the selected temperature. The blower will
run at low speed regardless of the air
distribution control setting.

Safety notes
For safety reasons, the retractable hardtop
can only be opened and closed when the
vehicle is standing still.
GObserve Safety notes, see page 51.GWarning!
To prevent possible accidents, only drive the
vehicle with the retractable hardtop either
completely closed and locked, or fully lowered

If the retractable hardtop does not completely
open or close, the roof hydraulics will lose
pressure and the retractable hardtop is
lowered
R after approximately 7 minutes when the
ignition is switched on
R after approximately 15 seconds when the
ignition is switched off
Shortly before the retractable hardtop is
lowered, a warning will sound. In the
multifunction display you will see 0059 and
the message Retractable Roof Lowering .
Properly lock the retractable hardtop before
continuing to drive. Otherwise, the unlocked
hardtop could open while the vehicle is in
motion and cause you to lose control of the
vehicle. You or others could be injured as a
result.
GWarning!
Before operating the retractable hardtop,
make sure there is no danger of anyone being
injured by the moving parts (retractable
hardtop, roof frame, and trunk lid).
