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.
It can only function optimally when you are
driving with the windows, the tilt/sliding
sunroof or tilt/sliding panel closed.
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 (
deactivated.
Follow the recommended settings for
heating and cooling given on the following
pages. Otherwise the windows could fog
