184 Controls in detail
Climate control
The climate control is operational when-
ever the engine is running. You can oper-
ate the climate control system in either the
automatic or manual mode. The system
cools or heats the interior depending on
the selected interior temperature and the
current outside temperature. Nearly all dust particles, pollutants and
odors are filtered out before outside air
enters the passenger compartment
through the air distribution system.
The air conditioning will not engage (no
cooling) if the
A/C mode is deactivated
(
page 189).
Warning!G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite on unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance
between unprotected pa rts of the body and
the air vents. If necessary, use the air distri-
bution control (
page 186) to direct the air
to air vents in the vehicle interior that are
not in the immediate area of unprotected
skin.
Warning!G
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility an d endangering you and
others.
iSevere conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (
page 193). The climate control will then
adjust the interior temperature to the set value
much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.

Climate control
Deactivating
Press button0 orP
(
page 183) once more.
The indicator lamp on the button goes
out. Defrosting is switched off.
Windshield fogged on the outside
Switch the windshield wipers on
(
page 58).
If the automatic mode of the climate
control is switched off:
Turn air distribution control 4
to a orY (
page 183).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment. Activating
Press button
, (page 183).
The indicator lamp on the button
comes on.
iThe cooling remains switched on.
iKeep this setting selected only until the
windshield is clear again.Warning!G
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window foggin g. If interior window
fogging persists, make sure the air
conditioning (
page 189) is activated, or
press button 0 orP .
iThe air recirculation mode is activated
automatically at high outside temperatures.
The indicator lamp on button , is not lit when
the air recirculation mode is switched on auto-
matically.
A quantity of outside air is added after approxi-
mately 30 minutes.
If you have turned off the air conditioning
(
page 189) or the outside temperature is
below 41°F (5°C), the air recirculation mode will
not switch on automatically.

Controls in detail
Climate control
Deactivating
Press button
, (page 183) once
more.
The indicator lamp on the button goes
out.
Air conditioning
The cooling function, only operational
when the engine is running, cools the
vehicle interior down to the selected
temperature. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up. 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
9 (page 183).
The indicator lamp on the button goes
out.
The cooling function switches off after
a short delay.iThe air recirculation mode is deactivated
automatically:

after 5 minutes if the outside temperature is
below approximately 41°F (5°C)

after 5 minutes if the air conditioning is
turned off

after 30 minutes if the outside temperature
is above approximately 41°F (5°C)
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 coo ling function, the inte-
rior air is not dried. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

Climate control
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press button9 (page 183) once
more.
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.
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 he at produced by the
engine. Activating
Turn the SmartKey in the starter switch
to position
0 or 1 (
page 39).
or
Remove the SmartKey from the starter
switch.
Press button 9 (page 183).
The indicator lamp on the button
comes on.
Deactivating
Press button 9 (page 183) once
more.
The indicator lamp on the button goes
out.!If the air conditioning cannot be turned on
again, this indicates that the air conditioning is
losing refrigerant. The compressor has turned
itself off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Light Truck Center.
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 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.
iThe residual heat is automatically turned off:

when the ignition is switched on

after about 30 minutes

if the coolant temperature is too low

if the battery voltage drops
