Climate control
Switching climate control system
on/off
Switching off
Set air volume control2 (page 174)
to position0.
Switching on
Switch on the ignition (page 37).
Set air volume control2 to any speed
(
page 174).
The previous settings are once again in
effect.
Setting the temperature
Use temperature controls1 and4
(
page 174) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).
The climate control will adjust to the set
temperature as fast as possible.
Increasing
Turn temperature control 1
and/or4 (
page 174) slightly
clockwise.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
Warning!G
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iIf the vehicle interior is hot, ventilate the in-
terior before driving off. 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.
When the retractable hardtop is closed, do not
obstruct air flow by placing objects 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
Ten blower speeds are available.
Use air volume control2
(
page 174) to adjust the air volume.
Basic settings
Heating (winter)
Turn temperature controls1and4
(
page 174) to the desired position.
Turn air volume control2
(
page 174) to level2 or higher.
Otherwise the windows may fog over.
Turn air distribution control3
(
page 174) to a position
betweenbandY.
Open the side air vents if necessary.
Close the center air vents.Heating (summer)
Turn air temperature
control1and4 (
page 174) to the
desired position.
Turn air volume control2
(
page 174) to level1 or higher.
Turn air distribution control3
(
page 174) to positiona.
Open the center and side air vents.
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 (page 174).
The indicator lamp on the button
comes on.
The air conditioning switches
automatically to the following
functions:

cooling on to dehumidify

maximum blowing and heating
power

air flows onto the windshield
and the front side windows
iKeep this setting selected only until the
windshield or the side windows are clear again.
iWhen you have activated the front defroster
using buttonP, no other settings are
possible.

Deactivating
Press buttonP (page 174) again.
The indicator lamp on the button goes
out.
The previous settings are once again in
effect.
Windshield fogged on the outside
Switch the windshield wipers on
(
page 56).
Turn air distribution control3 to
positionaorY (
page 174).
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 interior.
Activating
Briefly press button,
(
page 174).
The indicator lamp on the button
comes on.Deactivating
Press button, (page 174) again.
The indicator lamp on the button goes
out.
iThe cooling remains switched on.
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 180) is activated, or
press buttonP.
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 automatically
switched on.
A quantity of outside air is added after
approximately 30 minutes.
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)

181 Controls in detail
Climate control
Set air volume control2 (page 177)
to position5.
The ventilation operates with maximum
blower speed.
Turn temperature controls1and4
(
page 174) completely counterclock-
wise to their end stops.
The lowest temperature for both sides
is set.
Residual engine heat utilization
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.
Activating
Switch off the ignition (page 37).
Press button9 (page 174).
The indicator lamp on the button
comes on.Deactivating
Press button9 (page 174) again.
The indicator lamp on the button goes

iWhen the vehicle’s interior has cooled down
enough, reduce the air volume and increase the
air temperature to comfortable settings if
desired.
iHow long the system will provide heating
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 (page 37)

after about 30 minutes

if the battery voltage drops

Automatic climate control*
Nearly all dust particles, pollutants and
odors are filtered out before outside air
enters the interior through the air dis-
tribution system.
The air conditioning will not engage (no
cooling) if the A/Cmode is deactivated
(
page 184).Deactivating the climate control
system
Deactivating
Press button´ (page 184).

comes on.
Warning!G
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval.
A clogged filter will reduce the air volume to
the interior and the windows could fog up,
impairing visibility and endangering you and
others. Have a clogged filter replaced as
soon as possible at an authorized
Mercedes-Benz Center.
Warning!G
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
