Overview of climate control systems
Important safety notes
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.
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.
Automatic climate control regulates the
temperature and the humidity in the vehicle
interior and filters undesirable substances
from the air.
Automatic climate control is only operational
when the engine is running
operation is only achieved when you drive
with the side windows and tilt/sliding
sunroof/panorama roof with power tilt/
sliding panel closed.
Some functions of automatic climate control
can also be set via COMAND (
19 The "residual heat" function can only be switched on/off if the ignition is switched off.

Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
The integrated filter can remove most
particles of dust and removes pollen
completely. A clogged filter reduces the
amount of air supplied to the vehicle
interior. For this reason, you should always
observe the interval for replacing the filter,
which is specified in the Service Booklet.
As it depends on environmental conditions,
e.g. heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
It is possible that the interior blower may
be activated automatically 40 minutes after
the SmartKey is removed. The vehicle is
then ventilated for 30 minutes to dry the
air-conditioning system.
