Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only briefly
R switch on the cooling with air dehumidifica-
tion function
R switch on the windscreen demisting function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The cooling with air dehumidification function is
only available when the engine is running. Opti- mum climate control is only achieved with the
side windows closed.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience opening feature (Y
page 75). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odours. 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 this
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the engine
has been switched off depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry the automatic climate control. Control panel for THERMOTRONIC automatic climate control (2-zone)

due to a malfunction.
X Consult a qualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature of the dispensed air, the airflow and the air dis- tribution.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.

Important safety notes G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the navigation system.
General notes Correct functioning of the navigation system
depends, amongst other things, on GPS recep-
tion. In certain situations, GPS reception may be
impaired, there may be interference or there
may be no reception at all, e.g. in tunnels or
multi-storey car parks.
