186 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the automatic climate control sys-
tem in either the automatic or manual
mode. The system cools or heats the inte-
rior depending on the selected interior
temperature and the current outside tem-
perature.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/Cmode is deactivated
(
page 193).
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
on unprotected skin in the immediate area
of the air vents. Always keep sufficient dis-
tance between unprotected parts of the
body and the air vents. If necessary, use the
air distribution control (
page 185) to di-
rect the air to air vents in the vehicle interior
that are not in the immediate area of unpro-
tected skin.
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.
i
Severe 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. The automatic 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 win-
dow.

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.
i
The cooling remains switched on.
i
Keep 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 193) is activated, or
press buttonP.

A quantity of outside air is added after approxi-
mately 30 minutes.
i
The manually selected air recirculation

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)
Warning!
G
Never operate the windows 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 windows
can be immediately halted by releasing
the, button or by pressing and pulling
the respective window switch.

Automatic climate control
Deactivating
Press and hold button,.
The indicator lamp on the button goes
out. The air recirculation mode is deac-
tivated. The windows will return to their
previous position.
Air conditioning
The air conditioning (cooling) function is
operational when the engine is running and
cools the vehicle interior down to the se-
lected temperature. In addition, the cool-
ing function dehumidifies the air in the
vehicle interior, thus preventing the win-
dows from fogging up.Deactivating
It is possible to deactivate the cooling
function of the automatic climate control
system. The air in the vehicle will then no
longer be cooled or dehumidified.
Press button 2 (
page 185).
The indicator lamp on the button goes
out. The cooling function switches off
after a short delay.
i
A window will only return to its previous po-
sition if it has not moved to another position us-
ing the respective window switch after it was
closed with button
,
.
i
Condensation may drip out from underneath
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.

194 Controls in detailAutomatic climate controlActivating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press button 2 once more
(page 185).
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 heat produced by the
engine.Activating
With the SmartKey:
Turn the SmartKey in the starter switch
to position1 or0, or remove it from
the starter switch.
Press button T (
page 185).
The indicator lamp on the button
comes on.
With KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, the starter switch is in posi-
tion 0, same as with the SmartKey re-
moved from the starter switch)
Press button T (
page 185).
The indicator lamp on the button
comes on.
!
If the 2 button on the automatic climate
control panel starts to flash, this indicates that
the air conditioning is losing refrigerant. The
compressor has turned off. The air conditioning
cannot be turned on again.
Have the air conditioning checked at the
nearest authorized Mercedes-Benz Center.
i
How long the system will provide heating de-
pends on the coolant temperature and the se-
lected temperature. The blower will run at low
speed regardless of the air distribution control
setting.

Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters re-
quired for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet, or con-
tact an authorized Mercedes-Benz Center.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
