Notes on climate control
The climate control 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 is deactivated
( Y page 206).
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.
i If the vehicle interior is hot, ventilate the
interior before driving off, see "Summer
opening feature" ( Y page 127). The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
system
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.
