196 Controls in detailAutomatic climate control (CLK 500/CLK 55 AMG)The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing 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 modeAC
OFF
is activated or
A/C is deactivated (
page 204).
Warning
G
When operating the automatic 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 frostbite on unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the foot-
well air vents. If necessary change the air
flow using the air distribution controls to
direct the air away from the footwell air
vents (
page 198).
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.
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.

Setting the temperature
Use temperature controls3 andd for
the left side or6 andb for the right side
(page 195) 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).
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 automatic climate
control system in automatic mode, you
will only rarely need to adjust the
temperature, air volume and air
distribution.

Maximum cooling MAXCOOL
If the left and right air distribution controls
as well as the airflow volume control are
set toU (
page 195) and there is a
high need for cooling, the display
“MAXCOOL” appears.
This provides the fastest possible cooling
of the vehicle interior (when side windows
and tilt/sliding sunroof* are closed).
iThese settings should only be selected
for a short time.

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.

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).

The closing of the rear side windows can be
immediately halted by releasing the switch.
The door windows are equipped with the ex-
press-close and automatic reversal func-
tion. If a door window encounters an
obstruction that blocks its path in a circum-
stance where you pulled the switch past the
resistance point and released it to close the
window, the automatic reversal function will
stop the window and open it slightly.
If a door window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pulling and
holding the switch, by pressing and holding
button
‹
on the SmartKey, or by press-
