200 Controls in detailAutomatic climate controlCharcoal filter
An activated charcoal filter markedly re-
duces bad odors and removes pollutants
from air entering the passenger compart-
ment.
Activating
Press buttone (
page 193).
The indicator lamp on the button
comes on.
Deactivating

Press buttone (
page 193).
The indicator lamp on the button goes
out.
iPress and hold buttone for approx-
imately two seconds. The side windows
and tilt/sliding sunroof will close. You
can release buttone once the clos-
ing procedure has begun. The windows
and tilt/sliding sunroof continue clos-
ing until they are fully closed.
Warning!
G
Never operate the side windows and the
tilt/sliding sunroof if there is the possibility
of anyone being harmed by the closing pro-
cedure.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by pressing
the respective window switch. The closing of
the tilt/sliding sunroof can be immediately
halted by moving the tilt/sliding sunroof
switch in the overhead control panel in any
direction.
The closing of the side windows and
tilt/sliding sunroof can be reversed by again
pressing and holding buttone.
iPress and hold buttone for approx-
imately two seconds. The side windows
and or tilt/sliding sunroof will return to
their previous position. You can release
buttone once the opening proce-
dure has begun. The windows and
tilt/sliding sunroof continue opening
until they have reached their previous
position.
A window or tilt/sliding sunroof will
only return to its previous position if it
has not been moved to another posi-
tion using the respective window
switch or tilt/sliding sunroof switch af-
ter it was closed with buttone. A
window or tilt/sliding sunroof that was
moved will remain in its current posi-
tion if buttone is used to re-open
the remaining windows or tilt/sliding
sunroof.

201 Controls in detail
Automatic climate control
The system automatically switches to the
air recirculation mode if the carbon
monoxide (CO) or nitrogen oxide (NO
X)
concentration of the outside air increases
beyond a predetermined level, for example
in a tunnel.
The automatic air recirculation mode does
not function if ± is selected or if the
outside temperature has fallen below
41°F (5°C).
The activated charcoal filter should be
switched off when windows fog up on the
inside, or if the passenger compartment
needs to be quickly heated or cooled
down.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep battery drain to
a minimum, switch off the defroster as
soon as the rear window is clear. The de-
froster is automatically deactivated after approximately 6 to 17 minutes of opera-
tion depending on the outside tempera-
ture.
Activating

Press buttonF (
page 193).
The indicator lamp on the button
comes on.
Deactivating

Press buttonF (
page 193) again.
The indicator lamp on the button goes
out.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

202 Controls in detailAutomatic climate controlAir conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.
Press button± (
page 193).
The indicator lamp on the button±
comes on.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press± again (
page 193).
The indicator lamp on button ±
goes out.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Residual heat and ventilation
With the engine switched off, it is possible
to continue to heat or ventilate the interior.
This feature makes use of the residual heat
produced by the engine.
Activating
Turn the SmartKey in the starter switch
to position1 or 0, or remove it from the
starter switch.

Press buttonT (
page 193).
The indicator lamp on buttonT
comes on.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If button± on the automatic cli-
mate control panel starts to flash, this
indicates that the air conditioning is
losing refrigerant. The compressor has
turned itself off. The air conditioning
cannot be turned on again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.

The residual heat is automatically turned
off:


when the ignition is switched on


after approximately 30 minutes
(15 minutes when residual heat and
ventilation in the rear* are also
switched on)


if the battery voltage drops
Ventilated storage compartment
Depending on vehicle model and configu-
ration, your vehicle is equipped with a stor-
age compartment under the front armrest
(page 244) which can be ventilated
when the automatic air conditioning is
switched on. If so equipped, the switch is
located inside the storage compartment in
the front. The air temperature is about the
same as that of the center air vents.
The air volume is dependent on the setting
of:


air distribution control


air volume control


air vents in the dashboard
The air temperature is about the same as
that of the dashboard air vents. It cannot
be regulated separately.Switching ventilation on

Open the storage compartment in front
of the armrest, see “Storage compart-
ment in front of armrest” (
page 244).

Push upper portion of switch.
Switching ventilation off

Open the storage compartment in front
of the armrest, see “Storage compart-
ment in front of armrest” (
page 244).

Push lower portion of switch.
iHow long the system will provide heat-
ing depends on the coolant tempera-
ture and the temperature set by the
operator. The blower will run at speed
setting 1 regardless of the air distribu-
tion control setting.
!Do not obstruct the air vent in the stor-
age compartment.iThe compartment can get very warm
due to its confined space. When storing
heat sensitive objects in the compart-
ment, close the air vent while heating
the passenger compartment.

Automatic climate control
Rear passenger compartment climate control*
The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
The automatic climate control system is
adjustable individually for the rear passen-
ger compartment.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.The control panel is located in the rear cen-
ter console.
