186 Controls in detailAutomatic climate controlThe 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.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the ± mode is selected
(
page 193).
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents. Always keep sufficient dis-
tance between unprotected parts of the
body and the air vents. If necessary, use the
air distribution control (
page 185) to di-
rect the air to air vents in the vehicle interior
that are not in the immediate area of unpro-
tected skin.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iThe current climate control settings
(ON/OFF, temperature, air volume, ac-
tivated charcoal filter, etc.) are stored
for each SmartKey before it is removed
from the starter switch or when the ve-
hicle is locked using the SmartKey with
KEYLESS-GO* (
page 122).
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow, leaves, sticks,
and any other debris.
Do not obstruct air volume by placing
objects on the air volume-through ex-
haust slots below the rear window.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

can manually raise the air temperature for
the center and side air vents. The
thumbwheel4 is located between the
center air vents (

iWhen the air conditioning is switched
off, the outside air supply and circula-
tion are also switched off. Only choose
this setting for a short time. Otherwise
the windows could fog up.

188 Controls in detailAutomatic climate controlAdjusting air distribution

Automatic climate control
Deactivating
Press button, (
page 185).
The indicator lamp on the button goes
out.The air recirculation mode is deactivated
automatically:


after 5 minutes if the outside tempera-
ture is below approximately 41°F (5°C)


after 5 minutes if the air conditioning is
turned off


after 30 minutes if the outside temper-
ature is above approximately 41°F
(5°C)
At outside temperatures above 79°F
(26°C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
Charcoal filter
An activated charcoal filter markedly re-
duces bad odors and removes pollutants
from air entering the passenger compart-
ment.

was moved will remain in its current po-
sition if button, is used t o re-open
the remaining windows or tilt/sliding
sunroof.
iIf you press and hold buttone the
windows and tilt/sliding sunroof will

Automatic climate control
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 185).
The indicator lamp on the button
comes on.
Deactivating

Press buttonF (
page 185) again.
The indicator lamp on the button goes
out.
Air 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 185).
The indicator lamp on the button±
comes on.
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.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.

194 Controls in detailAutomatic climate controlActivating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press± again (
page 185).
The indicator lamp on the 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
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
Activating
Turn the SmartKey in the starter switch
to position1 or0, or remove it from
the starter switch.

Press buttonT (
page 185).
The indicator lamp on buttonT
comes on.Deactivating

Press buttonT (
page 185).
The indicator lamp on buttonT
goes out.
The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops
!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.
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.

195 Controls in detail
Automatic climate control
Ventilated storage compartment
Depending on vehicle model and configu-
ration, your vehicle is equipped with a stor-
age compartment under the front armrest
(page 232) 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 below the front armrest”
(page 232)

Push upper portion of switch.Switching ventilation off

Open the storage compartment in front
of the armrest, see “Storage compart-
ment below the front armrest”
(page 232).

Push lower portion of switch.!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.
