177 Controls in detail
Climate control
The climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent 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 AC
OFF
mode is selected
(
page 182).
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burns or frostbite to unprotected skin
in the immediate area of the air vents. Al-
ways keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary change the air flow
using the air distribution controls
(page 176) to direct the air away from the
footwell air vents.
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 fil-
ter 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.
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.

181 Controls in detail
Climate control
Deactivating
Press buttonO.
The indicator lamp on the button goes
out.
The air recirculation mode is deactivated
automatically:


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


after five minutes if the air conditioning
is turned off


after 30 minutes if the outside temper-
ature 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.
Deactivating the climate control sys-
tem
Deactivating
Press button M (
page 176).
Reactivating

Press button M again(
page 176).
or

Press any button on the climate control
panel (
page 176).
Warning!
G
Never operate the windows and
sliding / pop-up roof* or panorama
sliding / pop-up roof* if there is the possibil-
ity of anyone being harmed by the opening
or closing procedure.
In case the procedure causes potential dan-
ger:
Vehicles with sliding/pop-up roof: The pro-
cedure for the windows can be immediately
halted by pressing or pulling the respective
window switch. The procedure for the slid-
ing/pop-up roof can be immediately halted
by moving the switch for the sliding/pop-up
roof in any direction.
The closing of the side windows and the slid-
ing/pop-up roof can be reversed by again
pressing and holding theO button.
Vehicles with panorama sliding/pop-up
roof: The procedure for the windows and
panorama sliding/pop-up roof can be imme-
diately halted by releasing theO button.
iIf you keep buttonO pressed, the
side windows and sliding / pop-up
roof* or panorama sliding / pop-up
roof* will return to their previous posi-
tion.

182 Controls in detailClimate controlAir conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
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 button± (
page 176).
The indicator lamp on the button±
comes on.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press± again (
page 176).
The indicator lamp on the button±
goes out.
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
Turn the SmartKey in the starter switch
to position0or1, or remove it from
the starter switch.

Press buttonT (
page 176).
The indicator lamp on buttonT
comes on.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!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.

Setting the temperature
Use temperature control3 for the left
side or5 for the right side to separately
adjust the air temperature on each side of
the passenger compartment. You should
raise or lower the temperature setting in
small increments, preferably starting
at 72°F (22°C).

iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.
