Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 25). Overview of climate control systems
Important safety notes
Keep 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 dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The air filter cleans the air, thus improving the inte-
rior climate.
The cooling with air dehumidification function is only available when the engine is running.
Optimum climate control is only achieved
with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 146).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 100).
This will speed up the cooling process and
the desired interior temperature will be
reached more quickly. i
The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odours. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve 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 acti-
vated automatically 60 minutes after the
key has been removed depending on vari-
ous factors, e.g. the outside temperature.
The vehicle is then ventilated for
30 minutes to dry the automatic climate
control. 136

Automatic climate control Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the Ã
rocker switch. The indicator lamp in the
à rocker switch lights up.
R Set the temperature to 22 †. R
Only use the windscreen demisting func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode.
R Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated with the ignition switched off. The 138
Overview of climate control systemsClimate control

residual heat function is deactivated when
the ignition is switched on.
ECO start/stop function During automatic engine switch-off, the cli-
mate control only operates at a reduced capa- city. If you require the full climate control out-
put, you can switch off the ECO start/stop
function by pressing the ECO button
(Y page 164). Operating the climate control system
Switching climate control on/off
General notes When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could mist up.
Therefore, only switch off climate control
briefly.
Switch on climate control primarily using theà rocker switch (Y page 141).

(see the separate operating instructions). Activating/deactivating the cooling
with air dehumidification function
General notes If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only switch off cooling with air dehumidifica-
tion for a short period.
The cooling with air dehumidification function is only available when the engine is running.
The air inside the vehicle is cooled and dehu-midified according to the temperature selec-
ted.
Condensation may drip from the underside of
the vehicle when cooling mode is active. This is normal and not a sign that there is a mal-
function.

Problem
Possible causes/consequences and
M
MSolutions Vehicles with auxili-
ary heating:
cooling
with air dehumidifica-
tion can no longer be
switched on using
COMAND Online (see
the separate operating
instructions).
Vehicles without aux- iliary heating: the indi-
cator lamp in the Á
button flashes three
times or remains off.
Cooling with air dehu-
midification can also no longer be switched on
using COMAND Online
(see the separate oper-
ating instructions). Cooling with air dehumidification has been deactivated due to a
malfunction.
X Visit a qualified specialist workshop. Setting climate control to automatic
mode
General notes In automatic mode, the set temperature is
maintained automatically at a constant level. The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If desired, cooling with
air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi- cle will also not be dehumidified. The win-
dows can mist up more quickly. Therefore,
only switch off cooling with air dehumidifica-
tion for a short period. Setting climate control to automatic
mode X

lock (Y page 159).
X Set the desired temperature using the
