4-zone automatic climate control
Combination filter with
pollutant-sensitive air-recirculation
mode
The combination filter reduces pollutants
and unpleasant odors in the outside air.
The pollutant-sensitive air-recirculation
mode automatically switches off the
supply of outside air when pollutants are
detected in the air.

The pollutant-sensitive air-recirculation
mode is not possible if you have
switched off the air conditioning or if
the temperature falls below 41°F
(5°C).
Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.

Condensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
Warning!
If you turn off the cooling function, 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.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.
Press button 2 ( page 192)or
( page 193).
The indicator lamp on the button goes
out.
The cooling function is switched off.

Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press button 2 ( page 192)or
( page 193) again.
The indicator lamp on the button
comes on.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
!
If the air conditioning cannot be turned
on again, this indicates that the air con-
ditioning is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
