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

B í Single wipe/î to wipe the wind-
screen using washer fluid
X Switch on the power supply with the Start/
Stop button or the key (Y page 159).
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. 132

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

Problems with the "Cooling with air dehumidification" 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
Turn the key to position 2in the ignition
lock (Y page 159).
X Set the desired temperature using the
w rocker switch on the front control

ing instructions).
X To activate: press rocker switch Ãup

tion which has not been changed manually,
however, continues to be controlled automat- ically. When the manually set function
switches back to automatic mode, the indi-
cator lamp on the Ãrocker switch lights
up again. Setting the climate mode

Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heat-
ing can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can also temporarily deactivate the flow
of fresh air manually if unpleasant odours are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you switch on air-recirculation mode, the
windows can mist up more quickly, in partic-
ular at low temperatures. Only use air-recir-
culation mode briefly to prevent the windows misting up.
Activating/deactivating X
Turn the key to position 2in the ignition
lock (Y page 159).
X To activate: press thegrocker switch
up or down.

Air-recirculation mode is automatically acti-
vated at high levels of pollution or at high out- side temperatures. The indicator lamp in the
g rocker switch is not lit when automatic
air-recirculation mode is activated. Outside
air is added after about 30 minutes.
X To deactivate: press thegrocker
switch up or down.
