Decreasing air volume
With the help of a sun sensor, the automatic
climate control determines the relation of the
sun to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
The automatic climate control is operational
whenever the engine is running. It cools the
vehicle’s interior according to the angle and
intensity of the sun’s rays, the outside
temperature and the selected temperature.
You can operate the automatic climate
control in either the automatic or manual
mode.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.
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
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” (
page 127). The climate
control will then adjust the interior
temperature to the set value much faster.
