The climate control system is operational
whenever the engine is running. You can
operate the 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.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.

G Warning!

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.

The air conditioning will not engage (no
cooling) if the

A/C mode (

page 184) is

deactivated.

G Warning!

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.

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.

If the vehicle interior is hot, ventilate the

interior before driving off. The climate

control will then adjust the interior
temperature to the set value much faster.

G Warning!

When the climate control system is
switched off, the outside air supply and
circulation are also switched off. Only
choose this setting for a short time.
Otherwise the windows could fog up,
impairing visibility and endangering you
and others.
