201 Controls in detail
4-zone 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 A/C mode (
page 209) is
deactivated.Deactivating the climate control
system
Deactivating
Press button´ (
page 198) or
(
page 199) until the display4
(page 198) or (
page 199) is
cleared.
The climate control system is deacti-
vated.
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.
iSevere conditions (e.g. strong air pollu-
tion) 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 feature”
(page 217). The climate control will
then adjust the interior temperature to
the set value much faster.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
Warning!
G
When the climate control is switched off, the
outside air supply and circulation are also
switched off. Only choose this setting for a
short time. Otherwise the windows could
fog up, impairing visibility and endangering
you and others.

Adjusting air volume
Use buttonsU (
page 198) or
(
page 199) for automatic mode or air
volume buttons
orQ
(page 198) or (
page 199) to adjust air
volume manually.
Nine blower speeds are available.

Press button
to decrease or
buttonQ to increase air volume to
the desired level.
The indicator lamps on the
buttonsU go out.
AUTO
disappears
in the display4 (
page 198) or
(
page 199) and the automatic mode
is switched off. The selected blower
speed is shown in the display4.
Front defroster
You can use this setting to defrost the
windshield, for example if it is iced up.
You can also defog the windshield and the
side windows.
Activating
Press buttonP or 0
(page 198) or (
page 199).
The indicator lamp on the button
comes on. Display4 (
page 198) or
(
page 199) is cleared.The air conditioning switches
automatically to the following functions:


cooling on to dehumidify


maximum blowing and heating
power (depends on cooling
temperature)


air flows onto the windshield and
the front side windows


the air recirculation mode is
switched off
Deactivating

Press buttonP or 0
(page 198) or (
page 199) again.
The indicator lamp on the button goes
out. Defrosting is turned off.
The previous settings are once again in
effect.
iKeep this setting selected only until the
windshield or the side windows are
clear again.
iThe cooling remains switched on.

The indicator lamp on the button
comes on.
AUTO
appears in the
display4 (
page 198) or
(
page 199). The air volume and air
distribution are adjusted automatically.
If the automatic mode of the climate con-
trol is switched off:

Turn air distribution control1 and 7
to a or Y (
page 198) or
(
page 199).
Maximum cooling MAX COOL
If the left and right air distribution controls
as well as the airflow volume control are
set toU and there is a high need for
cooling, the display “MAX COOL” appears
in the front and rear display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof are closed).
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.
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 fogging. If interior window
fogging persists, make sure the air
conditioning (
page 209) is activated, or
press button0.

208 Controls in detail4-zone automatic climate controlDeactivating
Press button, (
page 198) or
(
page 199) again.
The indicator lamp on the button goes
out.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.
iThe air recirculation mode is deactivat-
ed automatically:

after 5 minutes if the outside tem-
perature is below
approximately 41°F (5°C)


after 5 minutes if the air condition-
ing is turned off


after 30 minutes if the outside tem-
perature is above approximately
41°F (5°C)
iPress and hold button, for approx-
imately 2 seconds. The side windows
and or tilt/sliding sunroof* will return
to their previous position. You can re-
lease button, once the opening
procedure has begun. The windows
and tilt/sliding sunroof* or tilt/sliding
panel* continue opening until they
have reached their previous position.
A window or tilt/sliding sunroof* will
only return to its previous position if it
has not been moved to another posi-
tion using the respective window
switch or tilt/sliding sunroof* switch
after it was closed with button,.
A window or tilt/sliding sunroof* that
has been moved will remain in its cur-
rent position if button, is used to
re-open the remaining windows or
tilt/sliding sunroof*.
iThe 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).

209 Controls in detail
4-zone automatic climate control
Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. 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 button2 (
page 198) or
(
page 199).
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 button2 (
page 198) or
(
page 199) 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.Residual heat and ventilation
(Canada only)
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.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.Warning!
G
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.
!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.iIf you switch on the residual heat
function when temperatures are high,
only the ventilation will be switched on.

Rear air conditioning
The rear climate control is adjusted via the
front climate control panel (
page 198) or
(
page 199) or the rear climate control
panel.
The rear climate control panel is located in
the rear center console.
iRegardless of the selected air volume,
the blower operates at low speed.iHow long the system will provide heat-
ing depends on

the coolant temperature


the temperature set by the operator
The blower will run at speed setting1
regardless of the air distribution
control setting.
iThe residual heat is automatically
turned off:

when the ignition is switched on


after about 30 minutes


if the battery voltage drops


if the coolant temperature is too
low
