!
Vehicles with a rain sensor: if the wind-
screen becomes dirty in dry weather con-
ditions, the windscreen wipers may be acti- vated inadvertently. This could damage the
windscreen wiper blades or scratch the
windscreen.
For this reason, you should always switch
off the windscreen wipers in dry weather. 1

X Switch on the power supply with the Start/
Stop button or the key (Y page 161).
X Turn the combination switch to the corre-
sponding position.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord- ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wipers to wipe more frequently.
The washer fluid is fed through the wiper
blades; when the screen is wiped with washer
fluid î, the water is emitted directly from
the blades.
If you push the combination switch beyond
the point of resistance in the direction of
arrow Band hold it in this position, the man- ual wash programme is activated. If you
briefly push the combination switch beyond
the point of resistance in the direction of
arrow B, the automatic wash programme is
activated.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions. Replacing the wiper blades
Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Hold the windscreen wiper arm firmly when you change the wiper blade. If you release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
! Always position the windscreen wiper
arms vertically before folding them away
from the windscreen. By doing so, you will
avoid damage to the bonnet. 134

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 26). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R activate the "Cooling with air dehumidifica-
tion" function
R activate the windscreen demisting 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" func-
tion is only available when the engine is run-
ning. Optimum climate control is only ach-
ieved 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 147).
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. 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 166). Operating the climate control system
Switching the 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 142).
Activating/deactivating X
Turn the key to position 2in the ignition
lock (Y page 161).
X To activate: press thetor! rocker
switch up or down.
The COMAND Online climate control menu
opens.
X Activate climate control via the air-condi-
tioning setting bar in COMAND Online (see
the separate operating instructions).
X To deactivate: press thetor!
rocker switch up or down.
The COMAND Online climate control menu
opens.
X Deactivate climate control via the air-con-
ditioning setting bar in COMAND Online
(see the separate operating instructions). Switching cooling with air dehumidi-
fication on/off
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,
deactivate the "Cooling with air dehumidifi-
cation" function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of the vehicle when cooling mode is active. Thisis normal and not a sign that there is a mal-
function.
Activating/deactivating Vehicles with auxiliary heating
X Activate/deactivate the cooling with air
dehumidification function via COMAND
Online (see the separate operating instruc-
tions).
Vehicles without auxiliary heating X To activate: press theÁrocker switch
up or down.
The indicator lamp above the rocker switch lights up.
or
X Activate the "Cooling with air dehumidifi-
cation" function via COMAND Online (see

switched on using
COMAND Online (see

instructions).
Vehicles without aux- iliary heating: the indi-
cator lamp in the Á

Cooling with air dehu-
midification can also no longer be switched on
using COMAND Online
(see the separate oper-
ating instructions). The cooling with air dehumidification function has been deactiva-
ted 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
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,
deactivate the "Cooling with air-dehumidifi-
cation" function only briefly. Setting climate control to automatic
mode X
