Automatic climate control*
The 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 interior through the air distribution
system.
The air conditioning will not engage (no
cooling) if the ±mode is selected
(
page 185).

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 on 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 to direct
the air away from the footwell air vents
(page 185).
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.

184 Controls in detailAutomatic climate control*
iWhen you turn the thumbwheels4
and9 upwards to the first stop, the
fixed center air vents3 anda and
the adjustable center air vents5
and8 are open.
When you turn the thumbwheels com-
pletely upwards, only the adjustable
center air vents5 and8 are open.
For draft-free ventilation, move the slid-
ers for the center air vents5 and8
to the middle position.
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.
When the retractable hardtop is closed,
do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
Keep the air intake grille in front of the
windshield free of snow and debris.

188 Controls in detailAutomatic climate control*Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.

Press air condition on/off switch±
(page 185).

Warning!
G
While driving, deactivate the air conditioning
only temporarily to prevent window fogging.iCondensation may drip from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
!If the indicator lamp on the air condi-
tion on/off switch± comes on
while driving and you cannot switch on
the air conditioning again by pressing
the air condition on/off switch±,
the air conditioning is losing

In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a
standstill and operate the system only when
road and traffic conditions permit. Always
pay full attention to traffic conditions first
before operating system controls while
driving.

(approximately 50 km/h), your car is
covering a distance of 44 feet
(approximately 14 m) every second.

Any alterations made to electronic
components can cause malfunctions.
The radio, amplifier, CD changer*, satellite
radio* and telephone* are interconnected.
When one of the components is not opera-
tional or has not been removed/replaced
properly, the function of other components
may be impaired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.
