183 Controls in detail
Automatic climate control
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 190).
Setting the temperature
Use temperature controls aand8
(page 182) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).
Increasing / decreasing

Press button a or 8 repeatedly until
the display shows the desired tempera-
ture.
The automatic climate control system
will correspondingly adjust the interior
air temperature.
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 102).
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.

185 Controls in detail
Automatic climate control
Adjusting manually
Press left or right buttonU.
The button emerges and theh,
», d and csymbols become
visible.

Turn the marking on the regulator to

188 Controls in detailAutomatic climate controlDeactivating
Press button, (
page 182).
The indicator lamp on the button goes
out.The air recirculation mode is deactivated
automatically:


after five minutes if the outside temper-
ature is below approximately 41°F
(5°C)


after five 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.
Activating
Press buttone (
page 182).
The indicator lamp on the button
comes on.
iThe air recirculation mode is activated
automatically:

at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases beyond a
predetermined level, for example in
a tunnel.
Please note that the charcoal filter
must be activated (
page 188) for the
air recirculation mode to be activated
automatically.
If you have turned off the air condition-
ing (
page 190) or the outside tem-
perature is below 41°F (5°C), the air
recirculation mode will not switch on
automatically.
iIf you keep button, pressed, the
side windows and the sliding/pop-up
roof will return to their previous posi-
tion.
iIf you keep buttone pressed, the
side windows and the sliding/pop-up
roof will close.

190 Controls in detailAutomatic climate control
Deactivating the climate control sys-tem
Deactivating
It is possible to completely deactivate the
automatic climate control system. 
Press button M (
page 182).
The display shows “0”.
Reactivating
There are several ways to reactivate the
automatic climate control system:

Press one of the following buttons,
M, P, U, a temperature con-
trol switch (
page 182) or air volume
switch 9 on the automatic climate
control panel.
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 182).
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.

191 Controls in detail
Automatic climate control
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press± again (
page 182).
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 or 0, or remove it from the
starter switch.

Press buttonT (
page 182).
The indicator lamp on buttonT
comes on.Deactivating

Press buttonT (
page 182).
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 the± 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.

192 Controls in detailAutomatic climate controlVentilated storage compartment (except S 55 AMG)
The storage compartment under the front
armrest (
page 233) can be ventilated
when the automatic air conditioning is
switched on. 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 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 232).

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 232).

Push lower portion of switch. Rear passenger compartment adjust-
able air vents
Rear center console air vents
1Left center air vent, adjustable
2Right center air vent, adjustable
3Thumbwheel for center air vents with
adjustable booster blower
!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.
