186 Controls in detailClimate control (CLK 320)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 en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the modeAC
OFF
is activated or
A/C is deactivated (
page 191).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burns or frost-
bite on unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary,
change the air flow using the air distribution
controls to direct the air away from the foot-
well air vents (
page 188).
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.

Deactivating
Set air volume control1 (

to position0.
Reactivating

Set air volume control1 (
page 185)
to any speed.
Setting the temperature
Use temperature controls2 and3
(page 185) 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).
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
“Opening (Summer opening feature)”
(page 253).
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing
objects on the air flow-through exhaust
slots below the rear window.
iWhen the air conditioning is switched
off, the outside air supply and circula-
tion are also switched off. Only choose
this setting for a short time. Otherwise
the windows could fog up.
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside. This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment.
Activating
Press button, (
page 195).
The indicator lamp on the button
comes on.
Warning!
G
When the outside temperature is
below 41°F (5°C), only switch to air
recirculation mode for short periods to
prevent window fogging.
Window fogging may impair visibility and
endanger you and others.
iIf you keep button, pressed, the
side windows and tilt/sliding sunroof*
will close.Warning
G
Never operate the side windows and the
tilt/sliding sunroof* if there is the possibility
of anyone being harmed by the closing
procedure.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by
releasing the, button or by pressing or
pulling the respective window switch. The
closing of the tilt/sliding sunroof* can be
immediately halted by releasing the,
button or by moving the tilt/sliding sunroof*
switch in the overhead control panel in any
direction.
iThe air recirculation mode is activated
automatically:

at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel (charcoal filter must be
activated for the air recirculation
mode to be activated automatically)
The indicator lamp on the, button
is not lit when the air recirculation
mode is automatically switched on.
After approx. 30 minutes, outside air is
added to the air inside the vehicle.
If you have turned off the air
conditioning (
page 204) or the out-
side temperature is below 41°F (5°C),
the air recirculation mode will not
switch on automatically.

202 Controls in detailAutomatic climate control (CLK 500/CLK 55 AMG)Deactivating
Press button, (
page 195).
The indicator lamp on the button goes
out.
The air recirculation mode is deactivated
automatically:


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


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside
temperature is above
approximately 41°F (5 °C)At outside temperatures above 79°F
(26 °C) the system will not automatically
switch back to outside air. A quantity of
outside air is added after approximately
30 minutes.
Charcoal filter
An activated charcoal filter markedly
reduces bad odors and removes pollutants
from air entering the passenger compart-
ment. The charcoal filter can be activated
or deactivated.
The system switches automatically to the
air recirculation mode, if the

carbon monoxide (CO)
or


nitrogen oxide (NO
X)
concentration of the outside air increases
beyond a predetermined level.
iIf you keep button, pressed, the
side windows and tilt/sliding sunroof*
will return to their previous position.
iThe automatic air recirculation mode
does not function if theAC
OFF
(indica-
tor lamp on button° illuminated)
mode is activated orA/C (indicator
lamp on button2 not lit) mode is
deactivated, or if the outside tempera-
ture has fallen below 41°F (5°C).
