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 167).
G
Warning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
