Convenience opening
Press button: for approximately
2 seconds.
The windows and/or tilt/sliding sun-
roof* will return to their previous posi-
tions. You can release button:
once the opening procedure has be-
gun. The windows and tilt/sliding sun-
roof* continue opening until they have
reached their previous positions. The
indicator lamp on the button goes out.
The air recirculation mode is deactivat-
ed.
Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle down to the selected interior tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thereby preventing the windows from fog-
ging up.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 button9 (page 232).
The indicator lamp on the button goes
out. The cooling function switches off
after a short delay.
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press button9 again.
The indicator lamp on the button
comes on.
The air conditioning uses the refrigerant
R-134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iA window or the tilt/sliding sunroof* will
only return to its previous position if it has not
been moved to another position using the re-
spective window switch or tilt/sliding sunroof*
switch after it was closed with button:.
iCondensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.
Warning!G
If you turn off the cooling function, the
interior air is not dried. The windows can fog
up more quickly. Window fogging may
impair visibility and endanger you and
others.

Using driver-side settings for all tem-
perature zones
You can use the settings of the driver’s
side, such as temperature, air volume and
air distribution, for all temperature zones.
These settings only need to be made once
and the automatic climate control system
will automatically regulate the settings for
all temperature zones quickly and comfort-
ably.Activating
Adjust the temperature, air volume and
air distribution (
page 232).
Press button; (page 232).
The indicator lamp on the button

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.!If the air conditioning cannot be turned on
again, this indicates that the air conditioning is
losing refrigerant. The compressor has turned
off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Light Truck Center.
iIf you manually set the temperature, air vol-
ume or air distribution for the passenger side or
the rear passenger compartment when the
MONO setting is active, the MONO setting will
be switched off.
iHow long the system will provide heating
depends on
the coolant temperature
the battery voltage
Regardless of the temperature and air volume
set on the automatic climate control panel, an
interior temperature is aimed at by 72°F (22°C)
and the blower runs on low speed to protect the
vehicle battery.
