Automatic climate control panel
The automatic climate control is operation-
al whenever the engine is running. You can
operate the automatic 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.Item

Warning!G
When operating the automatic climate
control, the air that enters the passenger
compartment through the air vents 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 air vents. If necessary, use the
air distribution control (
page 190) to di-
rect the air to air vents in the vehicle interior
that are not in the immediate area of unpro-
tected skin.

191 Controls in detail
Automatic climate control
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 198).Deactivating the automatic climate
control system
Deactivating
Press button ´ (page 190).
The indicator lamp on the button
comes on.Warning!G
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval.
A clogged filter will reduce the air volume to
the interior and the windows could fog up,
impairing visibility and endangering you and
others. Have a clogged filter replaced as
soon as possible at an authorized
Mercedes-Benz Center.
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.
iIf the vehicle interior is hot, ventilate the in-
terior 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.Warning!G
When the automatic climate control system
is switched off, the outside air supply and
circulation are also switched off. Only
choose this setting for a short time when the
retractable hardtop is closed. Otherwise the
windows could fog up, impairing visibility
and endangering you and others.
