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 9
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. G
Warning!
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 165) is
deactivated. G
Warning!
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.
X Keep 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
G
Warning!
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

Air volume and air distribution are adjusted
automatically. 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. G
Warning!
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.

G
Warning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold

(depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
X Keep the air intake grille in front of the
windshield

free of snow, leaves, sticks, and
any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from
obstruction.

MAX COOL is only available in U.S. vehicles
with automatic climate control.
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 à and there
is a high demand for cooling, MAX COOL is
activated. MAX COOL appears in display H
(Y page 163).
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. G
Warning!
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
¬.

i The manually selected air recirculation
mode is deactivated automatically:
R after 5 minutes if the outside
temperature is below approximately
41‡ (5†)
R after 5 minutes if the air conditioning is
turned off
R after 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.
i If

you switch on the residual heat function
when outside temperatures are high, only
the ventilation will be switched on.
i How long the system will provide heating
depends on the coolant temperature and
the selected temperature. The blower will
run at speed setting 1 regardless of the air
volume control setting.

Safety notes
For safety reasons, the retractable hardtop
can only be opened and closed when the
vehicle is standing still. G
Observe Safety notes, see page 45. G
Warning!
To prevent possible accidents, only drive the
vehicle with the retractable hardtop either
completely

closed and locked, or fully lowered
into its storage compartment.
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 K 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.
