Turn the combination switch to the corre-
sponding position.
In the Ä or Å position, the appropriate
wiping frequency is set automatically according
to the intensity of the rain. In the Å position,
the rain sensor is more sensitive than in
the Ä position, causing the windshield wip-
ers to wipe more frequently.
Vehicles with MAGIC VISION CONTROL: the
washer fluid is fed through the wiper blades and
when wiping with washer fluid î the washer
fluid is emitted directly from the blades.
Vehicles with MAGIC VISION CONTROL: if you
push and hold the combination switch beyond
the point of resistance in the direction of arrow
B, the manual wash program is activated. If you
briefly push and hold the combination switch
beyond the point of resistance in the direction of
arrow B, the automatic wash program is acti-
vated.
If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.
Replacing the wiper blades
Important safety notes
G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!
To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.
!
Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield, the windshield
may be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
!
Always position the windshield wiper arms
vertically before folding them away from the
windshield. By doing so, you will avoid dam-
age to the hood.

Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.

workshops (

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging 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 defrost windshield 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 interior cli-
mate.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
only available when the engine is running. For
hybrid vehicles, the "Cooling with air dehumidi-
fication" function is also available via the elec-
tric refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Y
page 164).
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Y
page 152).
i
Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Y
page 95). 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 odors. 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 Book-
let.
i
It is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.

Notes on using automatic climate
control
Climate control system
Below, you can find a number of notes and rec-
ommendations to help you use climate control
optimally.
R
Activate climate control using the Ã
rocker switch. The indicator lamp in the Ã
rocker switch lights up.
R
Set the temperature to 72 ‡ (22 †).
R
Only use the "Windshield defrosting" function
briefly until the windshield is clear again.
R
Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up,
since 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 deactivated
with the ignition switched off. The residual
heat function is switched off when the ignition
is switched on.
If you are controlling the rear-compartment cli-
mate control using the front control panel, note
the following:
R
If you set rear-compartment climate control
using the front control panel, the Y sym-
bol appears in the rear-compartment control
panel display.
R
If the rear-compartment climate control is set
using the front control panel, it cannot be set
at the same time using the rear control panel.
After completing the settings for the rear-
compartment climate control using the front
control panel, wait five seconds. You will then
be able to control the rear climate control
using the rear control panel.
R
After selecting the rear compartment set-
tings, the front climate control can be con-
trolled automatically again via the multimedia
system after five seconds.
Alternatively, you can select "Cancel rear
compartment" in the multimedia system air-
conditioning function bar.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Y
page 167).

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
available when the engine is running. For hybrid
vehicles, the "Cooling with air dehumidification"
function is also available via the electric refrig-
erant compressor when the engine is not 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 it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
