Overview of climate control systems
Important safety notes
GWARNING
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 blocked filter replaced at a Mercedes-
Benz Center as soon as possible.
GWARNING
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 controls 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 13
. Optimum
operation is only achieved if you drive with the
side windows and sliding sunroof closed.
You can also set some automatic climate
control functions via COMAND (Y page 239).
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature ( Y page 89).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter can filter out most
particles of dust, and completely filters out
pollen. 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 Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.
i It is possible that the 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.13 The residual heat function can only be activated/deactivated if the ignition is switched off.262Overview of climate control systemsClimate control

The service interval message informs you of
the next service due date.
The multifunction display shows a service
message for several seconds, e.g.:
Next service A Due in .. Days

The letter indicates how much time the
workshop will require to carry out the service
work. The letters displayed range from A for
a short service duration to H for a long service
duration.
The service interval display does not take into
account any periods of time during which the
battery is disconnected.
Maintaining the time-dependent service
schedule:XNote down the service due date displayed
in the multifunction display before
disconnecting the battery.
or
XSubtract the battery disconnection periods
from the service date shown on the display
after reconnecting the battery.
i The service interval display does not
provide any information regarding the
engine's oil level. Observe the notes on the
engine oil level ( Y page 421).
Information about Service
Resetting the service interval display
A qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, will reset
the service interval display after the
necessary service work has been carried out.
Further information, on maintenance for
example, can be obtained at an authorized
Mercedes-Benz Center or directly from
Mercedes-Benz.
! If the service interval display has been
reset unintentionally, have the setting
corrected at a Mercedes-Benz Center.
Have service work carried out as described
in the Maintenance Booklet. This may
otherwise lead to increased wear and
damage to the major assemblies or the
vehicle.
