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 indicator lamp on buttonT
goes out.
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.
